E-bike Servicing and Repair in London

Back to Blog

E-bikes are transforming London commuting, and they need a workshop that understands both the bicycle and the electrics. At Cycle Fix London we service e-bikes daily, from motor diagnostics to the mechanical wear that assistance quietly accelerates.

Why e-bikes wear faster

Motor torque is hard on drivetrains: chains, cassettes and chainrings wear noticeably faster than on an unassisted bike, and the extra weight and speed work the brakes harder too. If your e-bike is your daily transport, plan on more frequent chain checks and brake pad changes than a regular bike would need.

What we can do

  • Standard e-bike servicing: gears, brakes, wheels and safety checks, same day
  • Brake overhauls with pads and rotors matched to e-bike loads
  • Drivetrain replacement with e-bike rated chains and cassettes
  • Bosch drive unit service: a full strip down and rebuild of the motor, £365
  • Battery contact, wiring and connector checks alongside any service

Diagnostics before guesswork

If your motor cuts out, shows an error or loses assistance, we diagnose before we replace. Many faults turn out to be a worn speed sensor magnet, a damaged connector or a firmware issue rather than a dead motor, and finding that first can save you hundreds.

Book it in

Standard e-bike services are same day. Motor rebuilds are quoted and booked in advance so the bike is back on the road as quickly as parts allow. Book online in two minutes, or call the shop on 0207 820 0028 and we will talk it through.
