Performance Review: SURFACE604 QUAD

Acceleration / Speed

The Surface604 Quad felt very smooth, and stable when accelerating. It also accelerated fast enough to get back up to speed within a matter of seconds. The Quad maintained its speed quite well too, and it never felt like it was overworking itself to keep moving.

One of the big factors that make the Quad so smooth is its torque sensor, because of it we always had the right amount of power whether we were on flat ground, or going up a steep hill.

Shifting / Gear Range

The Surface604 Quad comes with the SRAM X5 9spd drivetrain and shifter, which felt great! The shifting was quick, smooth, and crisp which we really appreciated especially when offroad. Because of the snappy shifting we were able to hold our speed up hills, and around corners without having to worry about shifting in time to do so.

Having 9 gears to choose from was also very convenient and made the Quad that much more versatile and capable. The less you have to focus on shifting the more fun you’ll have, and we really felt that when riding the Quad.

Maxxis Rekon 27.5+ Tires

Handling (Cornering, slow speeds, etc…)

We tested the Quad on every type of terrain we could find, from singletrack, to gravel, to slickrock, to paved trail, and the Quad handled it all, and really shined once off road.

The Quad handled like a regular hardtail mountain bike with a little bit more weight on the rear end because of the rear hub motor. The motor placement kept the rear tire stuck to the ground, which helped a lot with traction on corners. Because of the motors power and the 9 speed gear range we were able to climb the steepest of hills, and keep our speed regardless of the terrain we were on.

The torque sensor also gave us the right amount of power and engagement the second we needed it which helped out loads with the steep climbs, and managed technically challenging terrain that we experienced from time to time when riding our local light trails.

The Maxxis Rekon 2.8 inch tires kept us stuck to the ground, and prowled over rocks and dirt with ease, and the 100mm Suntour XCM 32 Suspension Fork helped us stay in control, and comfortable when things got tough.

Because of mountain bike geometry, 100mm of suspension, and 2.8 inch wide tires, the Quad handles great, especially if you’re looking to do all terrain biking.

Overall, we think you’ll find that the Quad handles nicely on a wide variety of trails – from paved city paths, to light off-road single track. We were even able to ride some pretty technical rocky sections, even though this bike isn’t designed for and won’t perform as well on rocky or rooty technical trails.


The Surface604 Quad is really comfortable, especially for being a mountain bike. We attribute a lot of the comfort to the Velo Saddle, and the leather lock on grips Surface604 equipped this bike with.

These are the two biggest contact points on the bike aside from the pedals, and because of this we really value comfort at these points. After plenty of miles on the Quad all our riders agreed that the saddle is a great median between being comfortable, and still being performance oriented for off-road riding. We felt the grips were comfortable, but weren’t quite performance oriented enough for the style of bike the Quad is.

The 100mm SunTour XCM 32 suspension fork also helped us out with comfort, it smoothed out chatter in the trail and allowed us to ride farther because of reduced fatigue. In short, the SunTour XCM 32 helped us stay fresher, for longer, leading to more time spent hitting the trails.


Mountain Bike Geometry

Range Test: Surface604 Quad

We already had a good idea of how far the Quad would get on max pedal assist from our recent review of its brother, the Shred. The Shred has the exact same 500w motor, and 14ah battery as the Quad . They also both possess the same tire width and wheel size.

Given how similar the bikes are, we decided to range test the Shred using power assist level 5 (i.e. use the highest assist level) and then range test the Quad using power assist level 1 (i.e. use the lowest assist level).

On our max power range test, we ended up getting 36.73 miles over 2 hours and 16 minutes, with an average speed of 16.1. I did this test, and weigh right around 170 lbs, and climbed 1,340 ft in elevation.

For our minimum power range test, Josh (5’11 and 125 lbs) ended up riding 63.74 miles over 4 hrs and 24 minutes, climbing 3,144 ft.

In summary, we ended up getting between 36-63 miles, which easily backs up Surface604’s stated claim that the Quad can travel up to 45 miles on a single charge.


Surface604 Quad Range Test

Specs/Features: Electrical Components


The Quad comes with a Bafang 500w rear hub motor that’s designed to be vibration free. Combine that with Surface604’s torque sensor, and controller and you’ve got yourself a smooth consistent motor setup that feels like a mid drive motor when it comes to engagement.

We were all really satisfied with the motor setup on the Quad, it really tied together the bike for us and gave us stellar performance. Because of the quick, consistent engagement the torque sensor provides we were able to maneuver through technical terrain noticeably better than we could using bikes with a cadence sensor. The torque sensor also allowed the motor to give the right amount of power needed which added to the overall performance of the bike.


The Quad is powered by a 48v 14ah Samsung Lithium Ion battery. This Samsung Lithium Ion battery is sleek, and low profile. It takes more than one glance at the Quad to tell if it’s even an electric bike because of how the battery fits into the frame, which definitely adds to the looks department of the Quad.

The battery holds its charge quite well, as we discovered in our range test where we nearly got 64 miles on a single charge while riding at the lowest level of pedal assist. For us, this inspires longer rides and riding at a higher assist level. It was great to know we had a solid, high quality battery below us.

Pedal Assist

The Surface604 Quad comes with 5 total pedal assist levels, which is more than enough especially when paired with the 9 speed SRAM X5 drivetrain. We loved having a wide assortment of assistance levels on the Quad, and because of it we were always able to find the perfect difficulty and speed combo when riding.

We spent most of our time in assist levels 4 and 5 because of the speed and power they provide. With 45 total variations of gear/assist combos the Quad proved to be highly versatile and ready for anything, at any speed.


When it comes to ebike throttle there isn’t a lot of variation in design, however there is loads of variation in performance. While the push thumb throttle looks quite standard, it feels a lot smoother than a lot we have tested. This is likely because of the high end controller, and rear hub motor that Surface604 uses on the Quad.

The throttle was great for getting back up to speed, and accelerating from a stand still. It also came in handy on off road trails, as we were able to accelerate on parts of the trail that were difficult to pedal on.


The Quad comes with Surface604’s 3.5” Colored LCD Display. This display is not only visually appealing, but also gave us all the necessary information we needed when riding. The display allowed us to see our total miles, trip miles, current speed, and current wattage use which gave us a good idea of how the Quad was handling the ride. Thanks to the wattage meter, we were able to see which gears and pedal assist levels conserved the battery, and which ones drained it.



The Surface604 Quad comes with a Buchel Headlight that mounts to the stem. We honestly could have done without the light, as it’s not particularly bright or focused. With the Quad being a mountain bike, we don’t feel the light fits in with the rest of the bike.

The light feels more cruiser oriented to us, and if you plan on doing night rides we would suggest considering picking up some higher performance lights to emit your path.

If Surface604 decides to put lights on their future models, we would like to see a fork crown mounted light instead, as the lower light position will emit the path more, and be less distracting when riding.

Components & Accessories


The Surface604 Quad comes with Tektro Dorado Hydraulic Disc Brakes and 180mm rotors front and rear. If there is one component on the Quad that gets an A+ from our team here at Electric Bike Report, it would be these brakes.

These Dorado brakes performed as good as we could have asked for, as they were extremely responsive, powerful, and consistent. These brakes also provide a wide array of modulation when it comes to how hard you brake.

With the Quad being heavier and capable of higher speeds than a standard hardtail, quality brakes are critical to the overall performance of the bike, and Surface604 delivered with the Tektro Dorados.

Tektro Dorado Brakes

100MM Suntour XCM 32 Fork


The Quad comes stocked with a 100mm SunTour XCM 32 Spring fork, which from our experience is solid, but isn’t spectacular in any particular way. The XCM 32 helped smooth out chatter on trails and absorb impacts, but not quite as much as we would have liked to see.

We would have liked to see an air fork on the Quad, as air forks provide more adjustment and a softer more plush feeling, plus overall better performance than spring forks do. With the Quad being an upgrade from the Surface604 Shred, it only makes sense to have upgraded suspension too.

We think most riders will be just fine with the XCM 32 that comes on the Quad, but those who like to ride rugged terrain may feel the fork is lacking some performance.


The “X-Wing” Style 6061 Alloy frame is what really makes the Quad stand out in a crowd, in fact we wouldn’t be surprised if it’s why you clicked on this review in the first place! When we were testing the Quad we received plenty of questions and comments about the frame, wondering who made it was and how it felt. In short, the frame felt great.

The frame felt stiff and sturdy below us, and it also has standard mountain bike geometry. On top of that, the frame is relatively lightweight, and the welds are clean. Overall, the Quad’s frame performed just as good as it looked when riding.

Surface 604 Quad Frame

Sram X5 Drivetrain

Velo Saddle


The Quad comes with the SRAM X5 9 Speed Drivetrain, and a unique gold paint job that fits nicely with the rest of the bike. It also has a 38 tooth chainring to keep things moving. The X5 shifter is crisp, consistent, and it performed just as we’d hope it would. Surface604 made the right choice when it comes to the drivetrain in our eyes.

9 total gears gave us a wide range with plenty of variation in difficulty. We had a gear for steep hill climbs, straight aways, and everywhere in between the two. And no, this isn’t a SRAM XX1 Eagle Drivetrain, although it looks like it!

Grips and saddle

The leather grips, and Velo Saddle both add to the looks of the bike, and are quite comfortable. When riding off road, the leather grips felt a bit slick when holding on to them and we believe a tackier, more rubber based grip may benefit the performance of the Quad overall.

As far as the saddle goes, it’s plenty soft to ride on for hours at a time, and it’s also pretty good looking! We think most riders will be just fine with these components, and they are both easy to replace if that doesn’t end up being the case.


Surface604 has put Promax aluminium handlebars on the Quad, these bars have 60mm of rise with 9 degrees of back sweep and are 720mm wide. The rise was great for riding in an upright, yet performance oriented position. Our test riders that prefer mountain biking all would have liked a wider bar for stability and control, but agreed that it wasn’t too thin to be an issue. Riders who aren’t used to modern mountain bikes will likely be just fine with the 720mm width.


Surface604 has selected Gold Wellgo Platform Pedals for the Quad. These pedals match the color scheme of the rest of the bike nicely. These pedals have shown to be quite sturdy, and can withstand large pedal strikes too, the Wellgo Platform Pedals were grippy enough to keep our feet on the pedals through chatter and rough sections of the trail, which was definitely appreciated. Not only are these pedals good looking, they are also high quality in their build, and performance.


The Quad’s kickstand is a heavy duty aluminum kickstand, that they’ve placed far enough back on the chainstay that you’re still able to pedal with the kickstand down (not that we would recommend that). This kickstand tucks up next to the chainstay nicely and is sturdy enough to stay in place when up, and down.


One of our favorite features of the Surface604 Quad was definitely the Maxxis Rekon Tires (27.5 x 2.8) . These tires have a wide, blocky tread pattern that’s perfect for off road riding. We were able to climb extremely steep and loose hills without sliding out, and were able to corner with more speed and traction than we are used to.

Because of the 2.8 inch width we noticed improved balance and control at low speeds, and increased stability at high speeds – The Rekon’s 2.8 inch width felt like a happy median of rolling speeds, and traction.

The tan sidewalls of the Rekon tires was also a nice touch, as it fits the scheme of the Quad perfectly.

Summary Review / Where to Buy

The Surface604 Quad proved itself worthy on all the light to intermediate trails we rode it on, and showed that it was well engineered by the team at Surface604. We really liked having the torque sensor hooked up to the vibration free rear hub motor. The motor was quick to engage and consistent in feeling, and performance. This setup also was great at flattening hills, we got one of our fastest hill climb test time on the Quad.

The Quad always seemed to know how much power to give us when riding, and because of this we were able to tackle moderate technical off road terrain far better than we could have on a cadence/speed sensor bike. The Quads ability to mediate power output also allowed the bike to hold on to battery life for far longer than we were expecting.

You can purchase the Surface604 Quad directly from the manufacturer’s website, or use their dealer locator tool to find one near you.

We were very impressed with the maximum range of the Quad’s 48v battery. Knowing the Quad can get over 60 miles on a charge was definitely confidence inspiring to us, and we did some crazy voyages because of it.

The whole Electric Bike Report team agreed that the Quad felt just as good as it looked, and that the bike is a great value for the price you pay. With a quality frame, motor, sensor, tires, and more it’s hard not to love what the Quad has to offer. It’s unique, and can hang with the competition.

If you want to progress your riding, and knowledge of the area you live, a bike like the Quad is a great option. Those looking to adventure, and tackle off road trails and roads will surely like what the Quad offers. Surface604 has put lots of time, and engineering into the Quad, and we were able to see and feel. All in all, The Surface604 Quad proved to be a great adventure bike, and we enjoyed the unique experience the Quad offered us.



Surface604 Shred Review – 2021

Summary Review: Surface604 Shred

Surface604’s “Shred” is designed to live up to its name, and from our experience testing it, it does just that. With standard mountain bike geometry, an advanced torque sensor, and a powerful rear hub motor, the Shred prowls through light trails with ease.

As a casual or intermediate rider, you’ll appreciate the performance of the Shred right away. Although it took some time, Surface604 developed the Shred to be a quality trail bike that is affordable for the average customer.

The team at Electric Bike Report includes many avid mountain bikers who were looking forward to trying out Surface604’s Shred. Knowing the pride Surface604 has in its finely-tuned motor, we were very excited to see what the Shred could do on our local trails.

Video Review
  • The hub motor and torque sensor set up feels well-engineered and responds how we want. It engages smoothly and with the right amount of power regardless of the scenario. It’s also very quiet.
  • The Tektro Dorado Hydraulic Disk Brakes give a confident feel on the Shred because of their stopping power and modulation.
  • The Shred is playful and easy to move around despite being 50lbs and having most of the weight on the bike’s rear side.
  • The Shred has a good riding position, comfortable for longer rides but still feels “performance” oriented.
  • It performed well on diverse terrain and thrived on hardpack singletrack and gravel.
  • The Shred handles damp riding conditions very well. Everything performs correctly even when wet.
  • The battery readout isn’t very precise for a percentage based readout. However, it’s accurate enough to know when you’re close to complete depletion.
  • Repairing rear flats at home can be quite tedious as rear hub motor axles can be tough to drop out. This shouldn’t be much of an issue for your local bike shop mechanic if you can’t figure it out.

Performance Review: Surface604 Shred

Acceleration / Speed

The Shred has solid, stable acceleration and is decently fast when it comes to speed. During our “100 yard dash,” we clocked 12.16 seconds on the max pedal assist and 13.86 seconds on throttle only. These results are around the average times we clock with similarly spec’d ebikes.

The 500w motor accelerates how we would expect it to and has a very smooth, consistent feel once engaged. It was great to have a predictable hub motor, as some can be jolty and inconsistent. Because of this consistency, we were able to ride the Shred confidently on a wide variety of terrain.

Some ebike motors “flaunt” their wattage and accelerate too quickly and inconsistently, which results in you feeling like you’re going to fall off the back of the bike. That isn’t the case with the Shred, though. The engineers at Surface604 took some time fine-tuning the motor specific to the bike.

Shifting / Gear Range

The number of gears that come on the Shred provides an excellent range (9 gears). This gear range is optimized for off-road riding, which makes sense considering it’s a mountain bike. It does just as good of a job riding around town and paved trails. I wouldn’t mind slightly harder gearing, but I also ride my mountain bike (non-ebike) 3-4 times each week, plus 50-100 miles a week while I test ebikes. Unless you are pushing really hard, the gearing is going to work great for you.

The SRAM 9 speed shifter also has a crisp, quick feeling when shifting, which helps when shifting up or down multiple gears quickly.


Performance Review



Handling (Cornering, slow speeds, etc…)

The Shred handles quite well, and it seems to be because of its mountain bike geometry and a few of the key components.

From our test rides, we all noticed the 27.5 x 2.8 CST Patrol tires helped with cornering and handling, regardless of if we were on the road or off-road. These tires also helped dampen some of the chatter when riding over bumps or cracks, ultimately keeping us in control.

When off-road, the suspension fork absorbs the bumps and chatter well enough to keep the bike steady on its path. The Surface604 Shred is stable and well balanced, and after our testing, we believe most people will think the same.


For a trail bike, the Shred is quite comfortable. The handlebar sweep and rise keep the rider upright enough to be comfortable for long distances while still being in a good position to handle and maneuver.

The saddle feels good too. Surface604 is going for a more performance-oriented saddle here, and for what the bike is intended for, it makes sense. The saddle provided proficient softness during our testing, and we had no complaints about it. Overall we think most riders will find the Shred plenty comfortable for its intended purpose.


Made In Canada.

Range Test: Surface604 Shred

We put the Shred through its paces on our standard range test. We tested the Shred at max PAS 5 to see how far you can expect to ride on this battery/motor combo.

After over two hours of saddle time, the Shred finally gave out at just under 37 miles. We also had an average speed of 16.1mph on the ride.

The Surface604 Shred did a great job staying within its comfort zone when it came to max wattage and motor engagement. Sometimes eBikes will burn themselves out on steep hills or pedaling in the highest assist level, but that wasn’t the case at all with the Shred.

Surface 604 Range Test

SPECS/FEATURES: Electrical Components


The 500w rear hub motor from Bafang is an excellent installment to the Shred. The motor stays within its limits and doesn’t overwork itself – something we hope and expect to see with trail-oriented bikes.

The motor provides quick engagement, consistent acceleration, and plenty of power when needed. Because the motor feels like it stays within its limits and has a max output of 750w, the battery charge lasts longer than other similar ebikes.

As mentioned earlier, some ebikes will “flaunt” their max wattage output, but in some cases, those bikes burn themselves out relatively quickly, while the Shred does not.


The 48v 14Ah battery provides a sleek look to the ebike and plenty of long charge range. From our experience, you are likely to get above 25 miles on this battery on full throttle/assist before it depletes.

Like I showed above in our range test, I got nearly 37 miles on full pedal-assist!
This shows that Surface604 has paired and optimized a great motor and battery combo that work well together, and we have no complaints about the quality of the battery.

The only thing we would change is having a slightly more consistent, accurate battery readout on the display. The display reads out how much charge the ebike has left on a scale of 0%-100%. However, the numbers can be unpredictable when changing.

Sometimes the battery goes from 80% to 79%; other times, it will go from 80% to 71%. A more accurate battery readout would bring peace of mind to us when riding, as we would truly know how much charge we have left.


Pedal Assist

The Surface604 Shred comes with five total levels of pedal assist. The different levels are distinguishable from each other to the point where we could see which one we were in without looking down at the screen.

Thanks to the torque sensor on the Shred, the engagement on the assistance is relatively smooth when pedaling. Less expensive ebikes conventionally use a cadence sensor, which can tend to create motor lag when pedaling. This lag can be unpredictable and dangerous.

That’s not the case with the Shred, though. The Shred felt predictability and consistency when pedaling, which we appreciated, especially when climbing and riding off-road. We were pleased to see that Surface604 went with the torque sensor and would like to see more bikes utilize them.


The Surface604 Shred comes with a lever throttle on the handlebar’s left side and has a large range in how much it engages. We found this to be very useful because we didn’t need to go full throttle all the time. Sometimes we only needed a little boost here and there, and the wide range of engagement allowed us to do that.

The throttle helped immensely with hill climbs, technical terrain on trails, and keeping speed around tight corners and steep grades. After extensive testing, we believe that Surface604 has done a great job with its throttle to motor setup, and it only takes a few rides to notice that.

Shred Display

Integrated Battery

Front Buchel Light


Surface604 has their own 3.5inch colored display, that provides the rider with plenty of data about their ride and bike. The display is pretty standard, and offers slightly more vibrant colors than most ebikes around this price point.

Overall, we all were happy with the performance and quality of the display.


The light is visually appealing, and helps the rider be seen. However, we would love to see Surface 604 go with a fork crown mounted design, and maybe add an option for an upgraded light. I can see a lot of people wanting to ride off the beaten path with the Shred so a better light system could be useful.



The Tektro Dorado Hydraulic Disk Brakes are some of the better brakes we’ve ever had on an ebike of this price point. The consistency and stopping power when braking on the Shred is phenomenal. Because of this brake setup, we could brake later into corners and handle steep terrain with confidence. We all agreed that Surface604 did a great job with the brake selection for the Shred.

Braking was a category where we felt the Surface604 Shred excelled. The quad piston Tektro Dorado eMTB Specific 180mm Hydraulic Disc Brakes can stop on a dime and provide a wide variety of braking power.

To test these brakes, we reached 20mph and then stopped as quickly as we could five total times. Our average stopping distance was 15’11”. These are really solid results for how fast we were going.

These are higher-end brakes than some other sub $2,500 ebikes, and they provided us with plenty of confidence at higher speeds. Our test rider, Pierce, reached over 33 miles per hour on a descent and “was able to slow down to 0 in a matter of seconds.”

The Shred’s brakes check all the boxes in safety and performance.


The 100mm SR Suntour XCM 32” spring fork adds decent comfort and control to the Shred, and comes with a lockout adjustment. This fork gets the job done but can be a tad unforgiving on rougher terrain. It’s best suited for lighter trail riding, not for higher intensity trails. All in all, it might leave you wanting a little bit more.

We feel an air fork upgrade option for the Shred would be ideal for those doing more off-road or intense trail riding, as it’s more plush and provides fine-tuned adjustments when it comes to rider weight and rebound. We understand that Surface604 has a specific price range in mind, so having the spring fork makes sense. However, adding the air fork as an optional upgrade would be great to see.


Lockout Fork

Suntour XCM 32


The Surface604 Shred’s frame is made out of 6061 Aluminium Alloy. Surface604 designed the frame to have a Tapered Headtube, Custom Reinforced Battery Mounts, and Internal Cable Routing.

The frame felt sturdy regardless of where we were riding. The welds are low profile, and it’s apparent to us that the Surface604 design team put a lot of time and effort into the Shred’s frame design. The internal cable routing was appreciated as well.


Surface604 went with SRAM’s X5 9-Speed cassette and derailleur setup gave us proper gearing for every situation. This drivetrain gives the Shred the perfect gear range for climbing steep hills, and sprinting on straight aways.

The larger cassette on the Shred we nice because we never had to “mash” on the pedals to keep the bike moving.

Lockout Fork

Nebula Saddle

Grips and Saddle

Surface604 put Velo Grips and a Selle Royal Nebula saddle on the Shred. The grips are tacky and provide the rider with ample grip. The saddle is the right mix of performance and comfort.

After many miles on the Shred, it was obvious that these are useful additions to the ebike and that most people will like the feeling of them. The nice thing about grips and saddles is that they are easy to change and adjust should you want to try something else..


The Surface604 Shred is stocked with the 720mm Promax Aluminium handlebars with 30mm of rise and a 9-degree backsweep. In simpler terms, the handlebar is designed to be wide enough for stability and angled up and back enough to feel natural when riding.

From our testing, it did just that. The 720mm width was wide enough for stability, and the 30mm rise helped loads with comfort on off-road terrain.

Surface 604 has put the right bar on the Shred for width, height, and backsweep.


The Shred comes with Wellgo Platform pedals. These pedals are very standard and get the job done. If you are looking to do casual on and off-road riding, they’ll be just fine.

If you are looking to do more off-road riding/mountain biking, we recommend a more mountain bike oriented set of pedals, like the RaceFace Chesters.

Pedals like the Chesters add more traction and support over the Wellgo platform pedals for off-road riding. From our tests, the Wellgo Platform pedals can be slick if you are riding off-road terrain but are just fine for on-road/ paved path rides.


The Surface604 Shred comes with an adjustable heavy-duty aluminum kickstand. We were skeptical of having a kickstand on a mountain bike at first, but after testing the Shred we hardly noticed it was there.

The kickstand has a strong enough spring to keep the kickstand from bouncing around when riding and is far enough back on the chainstay that it doesn’t interfere with your pedals. The heavy-duty kickstand ended up being nice to have, and we are glad that Surface604 decided to add one.


The CST Patrol 27.5” x 2.8” tires on the Shred are the perfect size to have a good time and have plenty of grip.

The 2.8” width is a happy median between rolling speed and traction. We like that Surface604 went with an aggressive tire like the Patrol. Since the Shred is an ebike, you don’t have to worry about the knobby tires rolling too slowly. Instead, you get to experience all of their grip and cornering capabilities that they possess.

CST Patrol Tire


Summary Review / Where to Buy

Our experience testing the Surface604 Shred was a great one. We had a lot of fun seeing how the Shred performed as a mountain bike, as a commuter, and everything in between.

The Shred is an excellent example of how a hub motor can perform well on trails if set up properly. Typically mid-drive motors are the way to go on eMTB bikes, but this particular Bafang 500w hub motor puts up a good fight.

We enjoyed seeing how steep the Shred could climb and how it could handle different styles of terrain. After taking the Shred all around Southern Utah, we found that the Surface604 Shred is right at home on light trails (smooth hardpack singletrack), gravel roads, and around town on streets and paved trails. The CST tires do an outstanding job on this terrain, and we can see why Surface604 chose the tires they did.

We were also very impressed with the battery life on this ebike. The Shred has 27.5 wheels and tires that are nearly 3 inches wide, plus it’s an eMTB with a hub motor, and because of this, we weren’t expecting to get as far as we did on our range test. The battery holds its juice exceptionally well, and you’ll get more than enough mileage in before it finally dies.

You can purchase the Shred directly off of Surface604’s website here, or you can check an electric bike dealer near you.

Surface604 designed the Shred “to be able to handle all the terrain in the 604 area code “(British Columbia), and while we tested it, it handled the 435 area code too! We were happy to see the Shred prove itself worthy on even rougher terrain. We feel that this bike thrives in the Pacific Northwest, and it’s easy to see why.

In conclusion, if you are looking for a well-priced, well-engineered ebike to explore and adventure on, then the Surface604 Shred is a great option. As mentioned earlier, the Shred has lived up to its name, and we think anybody looking for a versatile bike will agree.
