Welcome to eBike Motor Centre, where eBike Motors get a Second Life

At eBike Motor Centre, we believe in more than just repairs. We believe in sustainability, circularity, and keeping ebike motors on the road for longer.

We’ve proudly become the go-to destination for ebike motor repairs, parts, and servicing, trusted by leading bike shops across the UK and supported by a growing international network of repair partners. From our workshop nestled in the heart of the New Forest, we provide expert services that extend the life of your ebike motor and reduce unnecessary waste or cost.

Originally founded as Performance Line Bearings in 2018, our mission remains clear: empower riders and shops to repair, not replace. Our commitment to sustainability means helping you avoid costly replacements by restoring motors that others might deem “unrepairable.”

“Throwing something away just because it stops working is wasteful, not sustainable.”

Peter Collard, Founder, 2018

 Trustindex verifies that the original source of the review is Google. I am super grateful to Dave and his colleagues.

I live in Australia and I have a Kalkhoff with a series 1 Impulse motor that was beginning to play up. There are Kalkhoff agents here but I had little luck with them looking at a "vintage" motor (the bike is only 13 years old!!).

I tripped over the centre when looking on Youtube for ideas to maybe fix it myself. I found a great interview on Youtube with eBike Motor Centre which impressed me.

I was planning a trip to London and I contacted the centre to enquire whether they would look at a series 1 motor. Dave replied to me immedeately assuring me that they refurbished them all the time and that they would be happy to sort it out while I was in London.

Process was super professional from start to finish as others have mentioned.

Just back in Oz last weekend and I fitted the motor yesterday and it is BRILLIANT!!! I'm over the moon that my vintage steed is back on the road and that I have another 13 years (maybe more after an expert refurb) service out of it.

Thanks again to eBike Motor Centre, really, really grateful.

 Trustindex verifies that the original source of the review is Google. Excellent service from start to finish. I sent my yamaha pw x2 motor in because it was feeling a bit jerky and noisey at high cadence in lower assist modes. I was given very good advice about it not needing a full overhaul. To me that shows a company comitted to their customers. Rather than wanting to make money.
The motor had an interim service with a couple of bearings replaced and 2 missing motor case bolts. I have to say after it's maiden voyage today. It is quieter, smoother and I can actually feel that in eco mode the motor is providing assist. From new I often wondered if eco was actually doing anything.
Any questions I asked during phone calls were always answered in full.
If you have any concerns for your motor you can trust these guys to be perfectly honest with you.

 Trustindex verifies that the original source of the review is Google. I purchased a new Specialized levo turbo in 2020 and up to July 2026 I had 3  motors replaced under warranty and now the bike is out of warranty and only covered 6300 miles from new I had another motor fail. I could have purchased an exchange motor from Specialized for £950 from my local bike shop but decided to send  the motor to eBike Motor Centre as I had seen various You Tube clips and reviews on the company .I was not disappointed with in a week of recieving the motor its was stripped down and I was sent pictures of the damaged parts which could of been repaired but having spoken to David Cousins who was very helpful decided to go for a exchange unit which is a gen 3 upgraded motor for £595 .Excellent service from start to finish would highly recommend .

 Trustindex verifies that the original source of the review is Google. I highly recommend E-bike Motor Centre. I’m absolutely over the moon. I requested a full overhaul, and sent my Bosch Gen 2 Performance line CX motor off for repair as the bearings/crank had seized, I honestly thought there was no hope for the motor. I was then told by EMC that they had received my motor and it was in the workshop. Within 10 working days they contacted me again and sent me an invoice telling me my motor had been repaired, WOW, very impressed with the service. Once I had paid the invoice the motor was sent back to me recorded delivery. Within 48 hrs I had it back and it looked brand new with the new seals fitted. With a slight adjustment to the chain guide fitted to the motor, I had it back on the bike with everything Working perfectly and no noises. I tried a few places in the North East to get it repaired and had no joy. Thank you so much for fixing my motor, I will definitely send my motor away again for that 2 year service.
