What we do
We first establish what is really wrong. You then hear what is needed and what it costs. We only start after your approval. We use only genuine parts available from Bosch, Bafang and Brose or their official suppliers.
Honest advice
Not every motor is worth overhauling. If a new motor is the better choice, we tell you honestly. Is your motor still under factory warranty? Please contact your bike shop first.
