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.

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.

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.



Evelo Delta X Review – 2021

Summary Review: Evelo Delta X

The Evelo Delta X is a capable, aggressive commuter bike. Evelo has taken a lot of time developing this ebike, which shows in its design and performance. The Delta X provides excellent handling, quick acceleration, smooth shifting, and a powerful mid-drive motor, all of which will add up to an impressive ebike.

With 120N.m of torque from the motor and adjustable top speeds up to 28mph, there isn’t a route that’s too steep or too difficult for the Delta X. If you want a commuter that gets you quickly from A to B with relative comfort and ease, then the Delta X should be on your radar.

Overall, the Evelo Delta X is a unique bike that’s designed for the hardcore commuter. If you encounter hills on your daily route, this bike will have you feeling like a superhero as you effortlessly fly up hills. Coming in around $3700, there is no compromising on components or performance, and we appreciated the experience the Delta X provided us with.

Other ebikes we’ve tested from Evelo have all been high-quality and provided us with a great ride. The team here at Electric Bike Report has waited with much anticipation to ride the Delta X after hearing Evelo describe this bike as “the perfect blend of power, comfort, and performance – the Delta X is our fastest model.”

Performance Review: Evelo Delta X

Acceleration / Speed

The first thought I had when I was riding the Delta X was “wow, this thing is really quick!”. The tire width and powerful motor complemented each other nicely, and I held speed around corners a lot better than I have on past ebikes.

When discussing the Delta X we all agreed upon the major fun factor this bike provides, and we felt a big factor in this was the speed and acceleration that this bike is capable of. We all were able to ride with a high average speed on the Delta X, and we agreed that the mid-drive motor was a great choice for the bike.

Shifting / Gear Range

It’s easy to enjoy the Nuvinci Shifter and Enviolo Transmission; they complement the ebike perfectly. The Nuvinci shifter provides smooth, seamless gear shifting. The Enviolo transmission offers a wide range of gearing, and because of this, no hill felt too steep while riding Delta X.

We always felt like we were in the right gear regardless of where we were riding, which ultimately kept us riding longer because of how comfortable it made us.

The shift indicator is also really cool, as it visually shows the grade of steepness for each gear. Not only was the shifting high performance, but the drivetrain itself also had an effortless, clean look to it.

In summary, we think that Evelo chose a great transmission setup for the Delta X.

Handling (Cornering, slow speeds, etc…)

The Delta X is on the easier end of the spectrum when it comes to handling. Whether you are riding tight turns or straightaways, this ebike does a phenomenal job. The Delta X’s wide tires, suspension fork, and wide handlebar all keep the ebike stuck to the line you put it on.

We noticed that we were hitting corners with more speed than some of the other ebikes we have tested, and this is mainly due to the “stuck to the ground” feeling the Delta X has. That feeling was confidence-inspiring because we didn’t feel like we would slide out or get bucked off line when cornering.


The Delta X was pretty standard on the comfort side of things. The saddle and grips were more performance-oriented than comfort-oriented, so comfort-based riders may want to consider swapping those items out for something a little softer and more plush.

That said, we believe that Evelo made the right decision with the grips and saddle they chose. Still, the ebike falls closer to the performance side of things rather than the comfort.

The Delta X has a very comfortable geometry that feels similar to a trail-oriented mountain bike. It is aggressive enough to get through the rough stuff, yet nimble and quick enough to climb and maneuver through just about anything.


Range Test: Evelo Delta X

We rode as far as we could on our range test on max assistance to see how long the battery would last. With how powerful the Delta X is, we suspected it would burn itself out quickly. Thankfully that wasn’t the case, and the Delta X went over 26 miles before it finally died.

Not only did it go quite far for how powerful it is, but it also held a high average speed the whole time with ease. Our test rider weighs 170lbs and was pedaling above 20mph nearly the entire time. So, it’s safe to assume that you’ll go up in battery range and speed as you go down in weight.

Evelo Delta X Range Test

SPECS/FEATURES: Electrical Components


The Delta X is equipped with a 48v 750w Bafang Mid-drive Motor with an astounding 120N.m of torque. During our testing, we immediately felt the torque and acceleration that the Delta X is capable of.

We also found the motor was quick to engage and very smooth when assisting us. It also flattened every single hill with relative ease.


The juice behind the Delta X is a lithium-Ion 48v 11.6ah battery designed with advanced battery management software. From our impressions, this software provided us with a genuine 100% to 0% charge. When we were at 5%, we had just as much power and torque as at 50%, which we appreciated from Evelo.

This was a great feature because sometimes Lithium-Ion batteries begin to “cut out” when they are nearing full depletion, but that wasn’t the case with this one. The battery is also uniquely integrated into the frame while still being an external setup.

Overall, A+ on the battery quality.

Integrated Battery Pack.

Bright LCD Display.

Front Headlight


In our opinion, Evelo always has excellent displays, and they continue to impress with their display quality on the Delta X. The Multi-Color 3.2” IPS Display Comes with a USB Charger and provides a very wide array of colors and brightness. The display shows a wide array of information, including your speed, assist level, wattage use, time, trip miles, and total mileage.

While many displays include the same features, it’s how Evelo displays these things that make a difference. It’s cleaner, brighter, and overall just more visually appealing than your average ebike display setup.


The Delta X has an Integrated Aluminium Headlight with Cree LED and a Tobest EB04 Rear Tail Lamp. The headlight and taillight add to the overall looks of the ebike and are great for visibility in low-light conditions.

If you plan on doing a lot of night riding at higher speeds, a secondary brighter light might come in handy. Given that this bike is so powerful, you’ll need to increase your rider profile if traveling quickly by night.

Overall, the lights add to the look of the ebike and will help you be seen in low-light situations.

Pedal Assist

The Delta X has five total assistance levels, and let me just say this bike can move! For a longer range, we rode the Delta X in the 20mph mode with throttle most of the time. When we rode in the 28mph setting, we immediately saw the Delta X’s true power and capability, which we thoroughly enjoyed experiencing.

We liked having two variations of class levels on the Delta X. Because of this, it almost felt like two ebikes in one. Regardless of the class you decide to ride the Delta X in, you’ll find yourself accelerating out of corners and holding speed uphill.

The Class Two setting is better suited for longer mileage rides, and the Class Three setting is better for high speeds and riding with time in mind.



The throttle adds another level of fun and efficiency when riding the Delta X. It reminds you of how powerful this ebike is every time you use it.

We found the placement of the throttle to be very convenient and easy to find when riding. The lever throttle design is a lot easier to use than grip shift throttles when it comes to hand fatigue.

Components and Accessories


Evelo has stocked the Delta X with Tektro 180mm Hydraulic disc brakes with brake cut-off switches. These brakes provide extreme stopping power, which is essential for how fast this bike can move.

We loved the hydraulic disk brakes’ modulation and feel and would like to see more ebikes use the hydraulic setup. These brakes are one of the stand-out features on the Delta X and are just as high performance as the rest of the ebike.

The Evelo Delta X has more than enough stopping power, and we were impressed by how easy it was to slow down on this ebike. The stopping power is mainly due to the hydraulic disk brakes, which provide a consistent feeling of engagement and a powerful set of calipers to grab the rotor.

Tektro Hydraulic Disc Brake.

100mm Suntour XCM Fork


We had a ton of fun riding this thing through puddles and mud. To our pleasant surprise, we stayed clean enough that we didn’t wear any of the water or mud home.

We believe the main reason these fenders work so well is because of the rubber guard at the base. It seems to cover the area of the tire that flings up the most grit.


The 100mm SR Suntour XCM adds an element of a mountain bike to the Delta X. It also keeps it stable and in control on corners and through less smooth surfaces.

We loved how much travel they went with on the Delta X’s suspension fork as it makes higher speeds more controllable and comfortable. The XCM fork also comes with a stiffness adjustment dial that adds to the Delta X’s overall versatility.


The frame is Hydroformed 6061 High Strength Aluminum Alloy, which felt lightweight and stable below us. The frame is unique because it has been formed to fit a battery within the downtube without the battery being internal.

Because of this, you have the best of both worlds, an easily removable battery and a battery that looks sleek that doesn’t “piggyback” off the down tube.


The Nuvinci N380 Continuous Variable Transmission is up there for one of our favorite components on the Delta X. It has smooth shifting, a unique feeling, and provides a wide gear range. The Nuvinci C8 cable-actuated shifter also makes shifting the ebike easy to understand.

The Continuous Variable Transmission eliminates the space in between gears, providing a seamless feeling. Because of the CVT drivetrain, the Delta X has a near-infinite gear ratio, quiet shifting, and a maintenance-free setup. You also don’t have to be moving when shifting the CVT, which isn’t the case for conventional drivetrains.


Grips and saddle

The Velo Rubber Grips are more on the performance end of the spectrum than the comfort side and provide a tacky feeling that’s easy to hold. The Selle Royal Astro Saddle feels like a hybrid saddle that’s a median between comfort and performance.

The saddle felt great on shorter rides, and on longer rides, the saddle kept our sit bones happy.


The 740mm FSA Comet Handlebar is another component that dips into the mountain bike world. The Comet Handlebar is wider than your standard commuter bar and helps with stability in general.

We also felt this handlebar adds to the stylish look of the ebike. For me, the bar makes the Delta X look ready for anything. The bar comes with a 9 degree back sweep and a 4-degree upsweep. In simpler terms, it puts you in the perfect riding position for good handling and comfort.


The Delta X’s VP-565 pedals are plenty grippy and come with reflectors to increase your visibility to others. We were confident in the make of these pedals, and they felt very stable below us even when pedaling out of the saddle.

Most riders will like these pedals just fine, as they have a good grip, durability, and visibility.


Evelo stocked the Delta X with 27.5″ x 2.8″ Schwalbe Super Moto-X tires, and we liked this choice for a couple of reasons. The Super Moto-X tires are puncture-resistant, nearly 3 inches wide, and have a fast-rolling tread pattern.

From the thrill-seeking riders to leisure-cruisers, we all agree that these tires smooth out rougher surfaces and that these are the right tires for the Delta X.

Bike Size

The Evelo Delta X is designed to fit rider heights 5’6” to 6’2”. We liked the fit and geometry of the Delta X quite a bit. It feels more aggressive than your average commuter, and it’s easy to maneuver and handle.

If you are close to the height range on either side, you’ll probably fit the bike decently. Just keep the intended height range in mind. For smaller riders, we recommend checking out our review of the Evelo Galaxy 500, which is designed for riders 4’10” to 5’10”.

Frame Geometry

Summary review / where to buy

If you read everything above this section, you can already tell we had a great time test riding the Evelo Delta X, and we think anybody who values speed and performance when riding will like it. The Delta X’s whopping 120N.m of motor torque made us feel like we unlocked a superpower when pedaling uphill, and it helped us accelerate up to speed quickly on flat ground.

We appreciated the amount of engineering that went into the battery design on the Delta X. The battery-saving technology is convenient, and the battery’s integration into the frame is unique. Evelo has created a quicker commuter than most and one that feels nearly as capable as a mountain bike.

The tier of components on the Evelo Delta X are quite high, and they all seem to fit the bike’s purpose quite well. A couple of examples include the Tektro hydraulic disk brakes w/180mm rotors, the Suntour XCM 100mm fork, and the 740mm FSA comet handlebar. These components felt like they were meant to be on the ebike and perform just the same.

Evelo operates under a direct-to-consumer business model where they mail the bike of you directly. Evelo does a great job of assembling most of the ebike (95%), so the remaining steps are easy for consumers. Evelo also offers a wide variety of accessories for their ebikes, and because of this, we are confident that you’ll be able to set up your Delta X precisely the way you like it.

If you are looking for a commuter/trail bike that’s quick, strong, and good-looking, the Delta X is a highly viable option. The Delta X is seemingly ready for any commuting-related task, no matter how difficult. Thanks to the mudflap-equipped fenders, we were riding the Delta X regardless of the weather.

We view the Delta X as more capable than a standard commuter ebike, and after tons of testing and discussion, we all agreed this ebike falls somewhere between a commuter bike and a trail rocket. Thanks to the modifiable top speed (from 20mph class two to 28mph class three), you get to decide which end of that spectrum you want to lean towards.
