Guides

This guide is compiled from manufacturer manuals and well-known bike care sources; it has not been reviewed by a mechanic. You can confirm the information with reliable sources and with our store. When in doubt about safety, don’t ride.

Stop riding if…

In these cases bring the bike to our store without riding it and don’t try to repair it yourself. Don’t charge a damaged e-bike battery. This list is not a diagnosis; if you are unsure, don’t ride.

  1. The brakes don’t stop the bike safely, or a brake lever reaches the handlebar.
  2. A wheel has play, is loose, or the rim wobbles noticeably.
  3. The handlebar or fork is loose, crooked or has play.
  4. You see a crack, dent or break in the frame, fork or handlebar — especially after a fall.
  5. An e-bike battery is damaged, swollen, overheating or smells.
