What to check when buying used
Inspection
Drivetrain wear
Check chain stretch, cassette teeth, chainrings, and shifting under load before negotiating price.
Inspection
Wheel condition
Inspect rims, hubs, spokes, and bearing play; ask about the tire age and any prior wheel rebuilds.
Inspection
Service history
Ask for service records covering bearings, brakes, drivetrain, and any frame or fork warranty work.
Inspection
Battery health
Request battery cycle count and any diagnostic report; older packs lose range and capacity.
Inspection
Motor warranty
Verify motor warranty status and any firmware updates from the manufacturer dealer.
