The EFB bike is identical to a conventional bike. Maintenance/repair operations are carried out in the same way as for a conventional bicycle (change a cable, a tire, brake, lubricate the chain, etc.). You can do it yourself or get in touch with the nearest bicycle dealer.In relation to specific elements (battery, motor), you should get in touch with a specialist or get in touch with us to study together the best solution and solve your problem as soon as possible. We have a partnership with a bicycle workshop.
