"A brilliant motor system that could render the lightweight ebike redundant"
"The clever part is the gearbox contained within Skarper’s ‘DiskDrive’ replacement rear brake disc."
״This partnership with Skarper demonstrates how F1 expertise can help to improve everyday technology for the benefit of the public״
Skarper is designed to fit disc brake bikes and has been tested on a wide selection of bicycle frames. The current Skarper unit fits bikes that can accept a 160mm disc rotor. If your bike has a 140mm rotor and you would like to use the Skarper eBike drive unit, a bike shop should be able to adapt your bicycle to Skarper’s 160mm rotor using an off-the-shelf 140mm to 160mm calliper adaptor – which can be purchased online or in most bike shops.Skarper’s eBike drive system is designed to work with 26-29” wheels. If you are unsure about your bike, send us your bike model or your question, and we would be happy to help. If your bike does not have a disc brake and you would like to use Skarper, please reach out to our partner Poshbikes. They can check your bike and if applicable, provide a solution through their network of installers by changing the rear hub of your bike to one that can accept a centerlock adapter. More information can be provided by Poshbikes and select members of our installer network.
If your Skarper doesn’t fit, you can contact us for technical advice. If after receiving advice you still cannot fit it on your bike and your Skarper is unused, you can return it for a full refund within 14 days of receiving your product. We strongly recommend checking your bike’s compatibility before ordering. If you ordered Skarper and realised that your bike does not fit before delivery, you can simply contact us to cancel your order and receive a full refund. Full details about our returns policy can be found in our Terms & Conditions.
Skarper is purpose-built and has been rigorously tested for city commuting, road cycling, light off-road trails, and gravel riding. Our eBike drive system is designed to fit any bike with a 160mm rear disc rotor including gravel and hardtail mountain bikes. If you have a mountain bike with a 180mm rotor, it may be possible for a bike shop to change your rotor size to160mm. We do not recommend using Skarper for full-suspension bikes, or riding in extreme downhill or cross-country mountain biking. In the future, we will be developing an MTB specific version – this will be a 180/200mm rotor size so as to be compatible with the vast majority of mountain bikes and cross-country bikes.
