Motor Overhaul Pricing

Our motor servicing is carried out in house in Bristol by our trained mechanics. As a process this generally entails : removing motor from the frame, splitting motor, removing and replacing any worn bearings or seals within the motor and resealing to factory specifications with fresh manufacturer grease and gaskets.

Some motors require a greater labour charge due to either the complexity of the design itself or the complexity of the e-bike surrounding it, which is why we have chosen to split the servicing into tiers, if you do not see your motor listed or are unsure what motor your ebike may have, feel free to enquire by phone or email.

Prices exclude parts and apply to out-of-warranty motors only. Service charges shown are inclusive of VAT. Any additional parts will be quoted prior to commencement of work, unless a pre-agreed limit is set at drop-off.
