Buying a used e-bike: the 10-point checklist

Updated 9 October 2026 · 5 min read

A good used e-bike can save you thousands. A bad one can cost you a battery — the most expensive part of the bike. Take this list with you.

  1. Check the serial number. It is usually stamped under the bottom bracket, where the cranks meet the frame. Check it matches the ad, then check it on the EbikeMate register. If it has been ground off or scratched out, walk away.
  2. Battery health. Ask to see the battery’s state of health in the maker’s app or on the display, or a shop’s diagnostic report. Above 85% is good; under 70% means a replacement is getting close.
  3. Kilometres. The odometer is on the display. Compare it to what the seller told you.
  4. Ride it in every assist level. The motor should pull smoothly with no grinding, clicking or cutting out. Try the throttle if it has one — it should stop helping at walking pace.
  5. Brakes. Squeeze each lever hard: it should feel firm, not spongy, and stop the bike quickly. Look at how much pad is left.
  6. Chain and gears. A worn chain on an e-bike wears out the cassette and chainring fast. A shop’s chain checker tells you in seconds.
  7. Look for damage. Cracks near welds, dents in the down tube (where the battery sits) and bent derailleur hangers. Any crack in the frame is a no.
  8. Charger, keys and accessories. Most batteries lock with a key. A missing charger can cost $150 or more to replace.
  9. Compliance label. In Queensland an e-bike ridden in public needs an EN 15194 or Legacy EPAC label from 1 March 2027. Read about the rules.
  10. Paperwork. Ask for the receipt and any service records. Pay at handover — never a deposit by bank transfer, gift card or crypto.

Meeting the seller

  • Meet in daylight, somewhere public.
  • Bring a friend if you can.
  • Ride it somewhere safe, away from traffic.
  • If the price looks too good to be true, it usually is.
On EbikeMate every used e-bike shows its kilometres, battery health and a measured condition grade, and the seller records the frame serial. Shops are ABN-checked by a person.

Where are you?

Your postcode decides what you can see. Batteries are pickup only, so they only show to buyers near the seller, and some items are not shown in every state.
