The Look & Feel of the Haibike Radius Tour
The Haibike Radius Tour has a unique look and ride style with its compact 20″ wheels and relatively low step frame.
A 6061 aluminum frame with hydroformed tubes is designed with a relatively low step over area near the center of the frame.
Getting on and off the Radius Tour is pretty easy which is nice when running quick errands around town.
The hydroformed aluminum tubes have a variety of interesting shapes ranging from triangular, rectangular, to the standard round tubes.
Frame flex is not very noticeable with the large tubes and solid design.
The extra triangle created by the top tube reinforcement tube adds to the style of the bike and offers a nice handle hold for picking the bike up.
The central battery location on the downtube combined with the mid drive motor creates a very centered weight distribution for the bike. This is good for overall handling of the bike in addition to making it easier to pick up.
The Haibike Radius Tour comes in 1 size that can fit a pretty wide range of riders from 5′ to around 6′ tall.
There is a lot of adjustability in the handlebar and seat post height so you can fit the bike to your size and preferred riding position.
It is currently equipped with a 450mm seatpost that does a good job of fitting many riders. I am 5′-11″ with a long inseam and at the maximum extension of the seatpost I am not able to get the full leg extension.
There may be a 550mm seatpost option in the future for the Radius Tour that will fit taller riders.
The stem angle can also be adjusted to provide more height and changes to the reach.
Another interesting feature is that the handlebar can be quickly turned 90 degrees (while keeping the front wheel straight) for storing in narrow areas and/or for portability.
In addition, the pedals are foldable which helps to keep the overall profile very narrow.
While the Haibike Radius Tour is not technically a folding eBike it can become very compact by dropping the seat and handlebar, turning the handlebar, and folding the pedals.
Its overall small footprint is good for storing in a small living space or for transporting in a car, truck, or van.
In addition to being compact for storage and portability its relatively small size has some benefits for the ride feel.
Getting on and off the bike is easy with its low step area and 20″ wheels.
Smaller 20″ wheel eBikes can make maneuvering crowded areas easier than full size bikes.
The Haibike Radius Tour corners quickly and the compact size works well in congested areas. In some ways it has the feeling of a BMX bike that can accelerate quickly while being very agile in the corners.
Compared to some folding bikes the Radius Tour frame feels very solid with minimal flex.
Smaller wheels do require more a bit more attention because they are not as forgiving as larger wheel bikes.
Bumps, crack, and potholes in the road are more abrupt because they don’t roll over or through those obstacles as well as larger 26″ or 29″ wheels.
To help take the edge off of rough roads Haibike spec’ed the 20″ x 2.15″ Schwalble Big Ben tires that have a stable ride feel and some built in suspension with their large “ballon style” air volume.
Schwalbe describes it well, “The Big Apple started off the Balloonbike trend ten years ago: Comfortable cycling without using complicated technology! Air cushion tires are used as natural suspension.”
When you run these in the lower pressure range (~30 psi) they have that suspension effect and it does help quiet a bit with the small bumps and cracks in the road.
The Big Ben tires are also capable of easy going dirt road riding which can be nice for exploring new routes around town or fun adventure rides.
Flat tires from thorns, glass, etc. are minimized with the RaceGuard puncture resistant liner built in to the tires.
Now let’s take a closer look at the ride position of the Haibike Radius Tour.
As mentioned before there is a lot of adjustability to the dial in the best fit and ride position for you with the highly adjustable stem and seat post.
You can set up the Radius Tour in a comfortable upright position that also helps for seeing everything around you. Or you can set it up for more of a hunched over performance riding position that is more efficient for longer rides.
The handlebar is fairly wide for a stable ride feel and they also have a couple inches of rise built in.
The Haibike saddle has a mid-width profile with a center relief section that is pretty comfortable for performance style rides.
Now let’s take a closer look at how the Haibike Radius Tour eBike system and drivetrain performs.
While the Radius Tour may have a compact look to it, the Yamaha PW mid drive motor really gives this bike some kick!
At 500 watts of power with up to 80 Nm of torque the Yamaha PW provides solid sustained power for maintaining near 20 mph on moderate climbs.
In the higher assist levels the bike has a sporty, punchy feel because of the motor power and the small wheels that are agile and can accelerate quickly.
In the lower assist levels the Yamaha PW system offers a mellow cruising ride feel which is good for riding in crowded areas or for fun easy going rides.
The Yamaha system does a nice job of blending the electric assist with your pedal power. It uses 3 sensors (torque, cadence, speed) to monitor your ride style and then provide you with the proportional assist based on the assist level you have selected.
The assist starts and stops as soon as you start pedaling and the transitions between no power to full power are very smooth.
All of this adds up to a very intuitive ride feel that follows your lead. If you are pedaling hard the system gives you a lot of assist and if you are just going easy the system gives you a similar mellow assist. And there is everything in between.
There are 4 different levels of pedal assist: Eco+, Eco, Standard, High. The pedal assist levels are adjusted with the up or down arrow buttons on the control pad.
The Eco+ and Eco levels give you a moderate amount of assist for an easy going ride around the neighborhood and/or if you want to get more of a workout. They are good modes for getting the most range out of the bike.
Standard and High give you a much more noticeable amount of “kick” and they have a fun and sporty ride feel. These levels are good for getting to work quickly with minimal sweat.
There is a walk mode button on the bottom of the control pad but it is not active for US models. So far it is only available for the European market.
Like a lot of mid drives, the Yamaha PW motor does some noise. At the lower speeds and higher pedaling cadences you can hear a whirring noise that tends to fade away as wind noise overtakes it at higher speeds.
One interesting component of the Radius Tour is the Chainrunner chain guard that rotates with the chain. It consists of a slotted casing made of highly flexible corrugated tube that protects your pant legs from getting greasy.
It works well and there doesn’t seem to be any noise when using it.
The Chainrunner is intended to keep the dirt out which should reduce the lubrication cycles. It is recommended that the cover be removed for lubrication and then reinstalled.
The combined pedal power and motor power is transmitted through the chain and back to the Shimano Nexus 8 speed internally geared rear hub.
Internally geared hubs consolidate all of the gearing with the rear hub for a very clean system compared to a cogset with derailleur.
The Shimano Nexus 8 speeds cover the gear range well for many riding conditions including steep hills. A benefit to the Nexus hub is that you can shift the gears when you are not pedaling.
This is good for when you want to get into the best gear ratio for accelerating from a stop or when transitioning quickly from a decent to a climb.
Some internally geared hubs don’t shift very well under power and that is true of the Nexus.
When climbing hills under substantial power it hesitates shifting to an easier gear. Once the power is reduced it will make the shift but that is difficult when you really want to maintain as much momentum on a climb.
There is a grip shifter on the right side of the handlebar that allows you to quick shift through multiple gears in one twist. A gear level indicator is located on the grip shifter.
The Yamaha PW system and the front and rear lights are powered by the 36V 13.6ah 500 Wh lithium battery that is well positioned in the main frame of the bike.
The battery weighs 6.60 pounds and it is removed by unlocking it with the supplied key and sliding the battery to the side.
With the battery removed the bike weighs 42.65 pounds. Removing the battery makes it a little easier to load into a car, RV or boat.
The battery can be fully charged from empty in about 4 hours with the included charger that is a little larger than a laptop charger.
Now let’s take a closer look at the Yamaha display that is located in the center of the handlebar.
It is very easy to see the info at a quick glance because the display is large and center on the handlebar. There is a backlight in the display for seeing it while riding at night.
The power level is interesting to watch because you can see how much the motor is contributing based on how much you are pedaling and the pedal assist level used.
The control pad on the left side of the handlebar is positioned well and the buttons are large enough and well laid out for easy adjustments while riding.
There is also has a small USB charging port that you can use to charge a smartphone when you are out and about.
Slowing the Haibike Radius Tour down is handled by the Shimano M445 hydraulic disc brakes with 160mm rotors front and rear.
These hydraulic brakes have a high quality feel with their extremely solid engagement. The stopping power is impressive and they modulate well between just a little braking to full braking for a quick stop.
The brake levers can be adjusted to fit the size of your hand so that the brake levers are easily within reach.
Haibike equipped the Radius Tour well with a full assortment of accessories for commuting and longer tour rides.
The front (Spanninga Kendo, 15 lux) and rear (Busch & Müller Xeltec) lights are built into the bike and they are powered by the eBike battery so you don’t have to worry about charging separate batteries for the lights.
The SKS plastic fenders have a solid structure and they blend in well with the overall bikes look.
An aluminum rear rack provides a platform to carry bags or baskets. The stated max cargo weight is 55 pounds (25 kg). It features a spring clip on top to easily carry some small cargo like clothing or a small box.
To round out the accessory package there is the bell on the right side of the handlebar and a solid kickstand.
Okay, let’s see how the Haibike Radius Tour did out on the open road!
Haibike Radius Tour Range Test Results:
Here is the real world information on how the Haibike Radius Tour electric bike performed on a riding circuit that includes hills, flats, traffic, wind (when available) etc.
While testing these bikes I like to put them through the toughest conditions to see where their bottom line is in regards to range and speed. I tested the Haibike Radius Tour the highest pedal assist level (High) with average pedaling on paved roads.
Range: As you can see from the GPS info that I recorded, the Haibike Radius Tour traveled 33 miles and did a total elevation gain of around 2,700 ft. Considering that I weigh 190 lbs and I pedaled at an average pace this is very good range for a 36 Volt 13.6 ah battery pack (500 Watt Hours) with a 500 watt motor assisting up to 20 mph.
Watt hours are the total energy in a battery pack and it is based on the volts x amp hours of a pack. This is a way to compare the size of the “gas tank” of electric bikes.
Please keep in mind that if you pedal more, weigh less than me, ride slower and/or you use the bike in terrain that is not as hilly you will get more range. These results are from tough testing.
Weight: The Haibike Radius Tour tips the scales at 49.25 lbs which is a moderate weight for a compact electric bike. Removing the battery brings it down to around 42.65 pounds which makes it a little easier to carry or load into a vehicle.
The weight distribution of the Haibike Radius Tour is very good because the battery is in the front part of the frame and the mid drive motor is centered on the bike. All of that weight is low which is great for overall bike handling.
Powerful & Sporty Ride Feel with Impressive Range: The powerful 500 watt Yamaha PW mid drive motor and the nimble 20″ wheels with a solid frame gives the Haibike Radius Tour a very sporty performance ride feel in the higher assist levels. It is impressive that the Radius tour went 33 miles with 2,700+ ft of climbing in the highest assist level. More moderate riding will provide more range.
Easy Riding: The Radius Tour is a very approachable eBike with its low step frame for ease of getting on and off the bike. The 20″ wheels are agile with wide tires for a stable ride feel. It’s highly adjustable stem and seatpost will fit many riders and the bike can be dialed in to fit your preferred riding position.
Portable & Storable: Even though the frame doesn’t fold the Radius Tour can become quickly compact and narrow for storage at home, work, or in a vehicle for easy storage and transport.
Shifting Under Power: When shifting to an easier gear under power the Shimano Nexus internally geared rear hub hesitates. Once the power is reduced it will make the shift but that is difficult when you really want to maintain as much momentum on a climb.
Motor Noise: Like a lot of mid drives, the Yamaha PW motor does some noise. At the lower speeds and higher pedaling cadences you can hear a whirring noise that tends to fade away as wind noise overtakes it at higher speeds.
Overall the Haibike Radius Tour is a nimble, sporty, and compact eBike that is good for everyday commuting and longer fun rides.
The powerful Yamaha PW 500 watt mid drive motor system and agile smaller wheels makes the Radius Tour an impressive performance eBike that is comfortable to ride.
Its adjustability helps with dialing in the fit of the bike and it is also helpful for creating a compact bike for storage and/or transport.
The Haibike Radius Tour features a high quality mix of components from Yamaha, Shimano, and Schwalbe for the price of $3,000 USD.
Please keep in mind that this is a relatively short term test. This testing can’t really give you the long term review of durability and reliability.
