You can now send or bring your ebike motor to us for service, bearing replacement or full overhaul. Although a fairly quick job to remove these motors, if you don’t have the tools, you can always ask your local bike shop to remove it for you. Our address can be found on our contact page.
A full service consists of fitting your motor to our test rig and ensuring everything is working correctly and sounding as it should. Next we open the motor, removing the drive train and all gearing. We inspect the wiring, bearings, bearing surfaces and gears. If all is ok? We clean and re-grease all gearing. The motor is then re-assembled with new O-rings and seals. Fitted to our test rig and then sent back £65.00 Inc VAT + Shipping Is it really worth it!?
Overhaul prices may vary depending on exactly which bearings require changing? If you’re unsure we will remove the right hand engine cover, inspect all bearings and contact you before commencing any work. If you don’t wish to proceed, we will replace the motor cover, send your motor back and just charge postage.
You’re also welcome to send in components like the clutch bearing assembly and we will change the
bearings and ship it back to you.
We have a basic guide to pricing below for the Bosch motors. Yamaha, Brose, Shimano, Impulse, Panasonic etc. to be added soon!
