You are 2.5 times more likely to have your bike stolen than your car. And as tools such as cordless angle grinders – which can quickly slice through metal – become easily available, a sturdy steel shackle or chain may no longer be enough.
Fortunately, lock design has come a long way in the last few years. Brands including Abus, Litelok, Kryptonite and Hiplok have introduced stronger materials, smarter mounting systems, and locks designed specifically for the fatter frames of e-bikes. You can now choose from ultra-tough U-locks, wearable chain locks, and compact folding models with real-world resistance to power tools. A good bike lock won’t make your bike theft-proof, but it can buy you time and give a thief enough reason to walk away.
