How old are the bike and battery?
The battery may have been replaced more recently than the bike. Ask about both ages and a receipt for any replacement.

Before you leave
Ask these questions first.
A serious seller can answer most basic questions directly. Ask before arranging a viewing.
How has the bike been used?
Daily commuting wears a bike differently from occasional leisure rides. Also ask where the battery was stored.
What maintenance has been done?
Ask for workshop receipts and repairs to the motor, display, brakes, chain, gears or electronics.
Why is it being sold?
The answer is not decisive, but should fit the age, condition, mileage and advert.
Biggest financial risk
The battery deserves
extra attention.
A full display gauge only proves the battery is charged. It does not show how much energy it can still store.
Ask for a battery test
A bike shop report is more useful than a promised range. Without one, allow for greater uncertainty.
Inspect battery and connection
Look for cracks, moisture, corrosion, damaged contacts and poor casing fit. The battery must click in without force.
Use the original charger
Check that plug and cable are intact and charging starts without errors. A plug that fits does not prove it is the right charger.
Ask about replacement
Check whether a compatible replacement battery is still available. Older or uncommon systems may make this difficult or expensive.
Inspect the whole bike
Six areas that reveal a lot.
Frame & fork
Look for cracks, dents, unusual welds and paint damage around joints. Crooked handlebars may indicate a fall.
Wheels & tyres
Lift and spin each wheel. It should run straight. Check hubs and headset for sideways play.
Brakes
Levers should not touch the handlebars. Discs should be straight; rims, pads and cables should not look worn out.
Chain & sprockets
Look for rust, sharp teeth and skipping. Heavy e-bikes can wear out the drivetrain faster.
Display & controls
Test buttons, lights and all modes. Warning codes or intermittent power while moving need investigation.
Keys & accessories
Check battery keys, frame lock, charger and spare keys. Agree exactly what is included.
The test ride
Ride further than
one quick lap.
Start without assistance and build up gently. This makes unexpected behaviour easier to feel and hear.
- 01
Start without the motor
The bike should roll, steer and brake normally. Electric assistance does not fix mechanical problems.
- 02
Try every assistance mode
Assistance should engage smoothly and stop when you stop pedalling. Watch for interruptions or errors.
- 03
Test under load
If possible, ride up a slope or bridge. Listen for clicking, scraping, knocking or an uneven motor sound.
- 04
Brake firmly and change gears
Test each brake separately somewhere safe. Try all gears and check the chain does not skip.

This check helps you inspect carefully but is not a technical inspection or guarantee. If unsure, ask a bike shop to assess the e-bike.
