Imagine transforming your traditional bike into an eBike using just one tool. Fortunately, Skarper is here to provide just that. This particular tool attaches to your bike and converts it into an e-bike. Skarper is designed to provide assistance to cyclists on the road or uphill. The prop offers a top speed of 20mph (or a limited speed of 15.5mph in “affected countries”), and all thanks to its 250W motor. It is powered by a 202Wh battery which can be fully charged in 2.5 hours. Skarper says his accessory has a maximum range of 37 miles and the system adapts to the disc brake bikes ranging from 160mm to 180mm. There is also a small caliper adapter for 140mm disc brakes.
