A super thick, core hardened steel chain with a heavy, top quality lock is perhaps the most secure way to lock your bike. However these chains are so heavy and cumbersome, that they generally work best as a second, stationary lock which you leave wherever your bike is regularly secured for long periods of time.
Investing in a suitable bike lock should be given nearly as much consideration as the bike itself, as insurance companies will take a dim view of a Â£1000 bike locked up with a Â£7.99 chain. The advice given by most insurers is to get a lock worth around 10% of the total bike cost. The bare minimum lock should go round the frame and bike rack, but ideally you should secure both wheels, too. Most bike locks are rated with Sold Secure levels, with bronze being the weakest and gold the strongest. So, whether youâre after a chain or a D-Lock or a cable, the range, weight, and width of locks out there can be a challenging affair. Here are some of the best.
