Reach out, and we’ll confirm whether your bike is Skarper-compatible.
Learn more about compatibility with rim brake
There are special wheel hubs designed for rim brake bicycles that can fit Skarper and can convert your rim brake bike into an electric bike. The best way to find out if your rim brake bike can work with Skarper’s kit is to contact us and we will link you to a local bike shop who will gladly make all the arrangements. This way, you can enjoy the bike that you love while adding an electric motor when you want it.
REAR TRIANGLE FEATURES
Skarper has been designed to fit almost all bikes
but does require certain clearances
Some features make Skarper difficult to fit.
If your bike has a geometry similar to the one shown, Skarper should fit.
However, if your frame has additional elements or a more complicated design, Reach out, and we’ll confirm whether your bike is Skarper-compatible.
Dropout Geometry
We’ve designed Skarper to fit most bike frames on the market. However, some frames with more complex geometry may pose a challenge. When checking if Skarper is compatible with your bike, please pay close attention to the chainstay and rear triangle
If your bike has a geometry similar to the one shown, Skarper should fit.
However, if your frame has additional elements or a more complicated design, Reach out, and we’ll confirm whether your bike is Skarper-compatible.
Kickstands on your chainstay
Will need to be removed
Chainstay Mounting plates
If your bike has a welded mounting plate on the chainstay then this may potentially prevent Skarper mounting to the disk.
Reach out, and we’ll confirm whether your bike is Skarper-compatible.
Panniers, Racks, and Mudguards
If you have panniers, racks, or mudguards mounted low at the same height as the wheel’s axle, they may interfere with attaching Skarper and could need to be removed in order to use Skarper.
SPECIFIC CONSIDERATIONS
Skarper fits standard rear wheel hubs
Skarper was designed to fit all standard rear wheel hubs. However, with some specialist hubs such as Rohloffs, Skarper may not fit.
Reach out, and we’ll confirm whether your bike is Skarper-compatible.
Skarper’s disc rotor is 160mm only
Skarper currently comes with a 160mm rotor only. Even if your bike has 140mm or 180mm disc, most bikes can fit a 160mm rotor with simple adaption. A bike mechanic should be able to check and adjust your rear caliper to accept a 160mm rotor or confirm in the unlikely event that your rotor is not compatible.
Reach out, and we’ll confirm whether your bike is Skarper-compatible.
Skarper designed for wheels 26”-29”
If your wheels are below 26”, feel free to reach out and we will check if your bike is compatible.
SKARPER WILL NOT FIT PROPERLY
IF ANY OF THE FOLLOWING APPLY:
Chainstay length under 415mm
This is because Skarper will clash with the pedal. If your chainstay is shorter – measure the distance from the axle to the edge of the crank in its rear horizontal position. If it is more than 220 mm, Skarper should fit.
Fixie bike
As Skarper is pedal assist, attaching Skarper to a fixie bike can be dangerous. As long as the wheel keeps on pedalling the modor will continue to provide assistance
eBike
Skarper has been designed to work safely when connected to normal bicycles and not been tested with eBikes.
Rohloff hubs
Rohloff hubs are wider than the industry standard and therefore DiskDrive disk brake rotors cannot be installed on bikes with Rohloff hubs.
Tricycle
Skarper was not designed to fit with tricycles with two wheels in the back. It was designed for a bike with single rear wheel. If your tricycle has two wheels at the front Skarper may fit. As long as the rest of the conditions above applies, and the rear of the bike behaves like a normal bicycle.
Wheels over 29’’
Skarper was designed for wheels from 26”-29”. As the speed controller measures speed at the wheel, using Skarper will wheels above 29” will result in Skarper providing assistance above the speed limit, making your eBike not road legal and therefore it is forbidden to do so unless on private roads.
