Repair or replace your e-bike? How to decide

Most broken e-bikes and scooters can be fixed. Many common faults are wear parts or plug-in parts, and keeping a bike running keeps its battery, motor and frame out of the waste stream.

Usually worth repairing

• Brakes, tires, chains and cables. These are wear parts on any bike. Bosch lists the chain among wearing parts and has dealers check brakes and tire tread at service (Bosch owner guide). Replacing a chain on time also saves the far pricier cassette and chainrings (Park Tool chain wear).
• A throttle, sensor or display fault. Bafang's code list, for example, treats a failed throttle, speed sensor or display as a part to swap (Bafang C271 manual).
• A charger. If a known-good charger from the maker charges the battery, you only need a new charger. Use the maker's own model, never a universal one (CPSC charger warning).
• A worn battery on a bike whose frame and motor are fine. Batteries are wear parts (Bosch battery FAQ). Replace it with a pack the maker has approved for your bike (CPSC micromobility center).

Harder calls

• A failed motor. Ask the maker or a shop what replacement parts exist for your model before you decide.
• Damage to the frame. CPSC lists the frame in its pre-ride damage check. Don't ride a cracked frame, and have a shop inspect it (CPSC micromobility center).
• A battery the maker no longer supplies. Don't fall back on a pack rebuilt from used cells or reworked by someone unqualified, which CPSC warns against (CPSC micromobility center).

Check for recalls first

If a recall covers your bike or battery, the maker may repair or replace it. Search CPSC's recall list and follow the maker's instructions in the notice (CPSC recalls, Battery Network rider guide).

If it can't be saved

Never put a lithium-ion battery in the trash or general recycling. Take it to a battery recycler or hazardous waste site (CPSC micromobility center). Bosch says your bike dealer takes back used Bosch batteries, and The Battery Network's e-bike program lists drop-off points for participating brands (Bosch battery safety, Battery Network e-bike program). Wheels, brakes, racks and displays can often go to a shop or another rider.
