Compact, solid and easy to use – the Trelock BC 280 is a practical 5 mm chain lock with an integrated padlock, designed for everyday city protection.
Looking for a reliable chain lock that doesn’t feel bulky or overcomplicated? The BC 280 strikes the right balance between convenience and security. Its 5 mm hardened steel chain links create a durable structure ready for daily urban use.
The integrated padlock is made of hardened steel and features a cylinder protected against drilling, adding an extra layer of resistance where it matters most. No separate lock to carry, no unnecessary parts – just a clean, practical solution.
A resistant neoprene cover protects your bike’s paintwork from scratches, so you can secure your frame, seat post or rear triangle without worrying about cosmetic damage. With an 85 cm length, you get enough flexibility to lock your bike to racks, railings or fences.
Rated 6/18 in the Trelock security scale, the BC 280 is an excellent choice for everyday protection in urban environments. The set includes 2 keys, and if needed, you can order additional keys via the official Trelock website.
At 710 g, it’s light enough to carry comfortably, yet solid enough to give you real peace of mind.
