Transform your bike into a lightweight e-bike with this clip-on electric assist. Skarper adds power as you pedal, responding instantly to how you ride. Push your fitness, ride further, or take on tougher routes without changing how your bike feels.

Description

Turn the bike you already love into a capable e‑bike in seconds. The Skarper eBike Drive System clips to a dedicated DiskDrive rear rotor to deliver smooth, quiet assistance when you want it, then pops off just as quickly when you don't. No frame mods, no messy wiring, just simple clip‑on power that keeps your bike feeling like your bike.

Climb with a lower heart rate, push into headwinds without grinding, and arrive fresher on big days out. Keep the pure ride feel for training or group rides by removing the drive in moments. Charge it off the bike, throw it in a bag, and you are set for the ride home.

Skarper is a smart solution for riders who want extra assistance without changing the bike that already fits, handles, and looks right. For weekday commutes, weekend loops, and everything between, Skarper adds real‑world range and confidence without compromise.

*Compatibility note: Skarper does not work with SRAM Apex or Shimano UR-300 disc brake calipers.
