# Best heavy-duty locks for e-bikes Source: https://pedalandvolt.co.uk/best/best-ebike-locks Publisher: Pedal and Volt. Picks are based on what the Amazon listings state, not on hands-on testing. Method: https://pedalandvolt.co.uk/how-we-pick An e-bike is a bigger target than an ordinary bike, so the lock deserves real thought. The Sold Secure rating is the clearest guide in the UK: Gold and Diamond are the top grades, and there is a separate powered cycle scale for e-bikes and motorbikes. Insurers often name a minimum grade, so check your policy first. After the rating, compare shackle or chain thickness, weight (you will carry it every ride) and the internal size, which decides whether the lock fits round a fat down tube and a stand. No lock is theft-proof; a good one only buys time. This guide compares seven heavy-duty D-locks and chains using the ratings and figures each maker lists. Where a listing does not state a Sold Secure grade, we say so. ## Products ### 1.
