Why convert your bike?

Converting your bike to electric gives you a more powerful system than most new e-bikes from shops – at a more affordable price.

More motor power

A mid-drive motor offers more torque than motors on most factory e-bikes. Reliable even on the steepest hills.

Longer range

With batteries up to 1260 Wh, range can reach 200 km – depending on terrain, riding style and battery choice.

Lighter bike

The motor weighs only 3.5 kg, the battery as well. Total weight of a converted bike averages around 20 kg – less than most new e-bikes.

Low maintenance costs

Every component can be serviced and replaced individually. While competitors often replace the entire motor or battery on failure, we only replace the part that's needed.

Longer warranty

2 years warranty on the motor and 3 years on the battery. With regular maintenance, the system serves reliably long-term.

Save money

A conversion costs €800 to €1,200, significantly less than a new e-bike – and you get a more powerful system on a bike you already know.
