Preserving evidence after an e-bike crash

Don't repair, sell or return it. Store it somewhere dry and photograph it from every side, including the class label and serial number.

Don't charge or open a damaged battery. Store it away from living areas, ideally outdoors in a non-flammable container. After a fire, keep the remains — investigators can often find the cause.

Screenshot and export data from the bike's app, Strava, fitness watches, Citi Bike or delivery apps: speed, route, assist level and time. Request it before it's deleted.

Keep it, even if cracked. Damage shows how hard the impact was and that you wore it.

Receipts, product listings, manuals, warranty and any recall notices. Screenshot online listings now.

Nearby cameras, doorbells and dashcams overwrite footage quickly — often within days. Ask for it right away.
