Poor Theft Protection

Ordinary cable locks can be cut within seconds using small pocket cutters, which leaves your bike exposed.

Brilliant security! I ride across Central London daily, and it's the first lock that never drags me down yet feels incredibly solid. Being able to deploy it in 3 seconds is a lifesaver whenever I'm rushing.

Cycling is a family activity for us, and we appreciate that a single lock secures two bikes at the same time. I've stopped lugging several bulky D-locks in my panniers. It's compact and quiet, and the kids can use it easily too.

I've tried plenty of locks, but ViosChain copes with our wet climate better than any. The ABS housing genuinely keeps rust at bay, and the coating hasn't left a single scratch on my carbon frame. Highly recommend!

Answers to the main things owners ask about the lock

How can I set my combination?

Choosing a code takes only moments. Turn the internal dials to pick your own 4-digit number. With 10,000 possible combinations, cracking it is extremely hard, and you need never fret about misplacing a key at the train station.

Does it truly resist cutting?

Hardened military-grade steel forms the links, and it has been specially treated to withstand cutting, sawing and tampering. Ordinary chain locks cannot equal the added structural strength that comes from the seamless rivets.

Could it rust in the rain?

Absolutely. ViosChain features a durable anti-scratch coating plus an ABS housing. Together these shield the steel from rust and corrosion, which suits the unpredictable British weather very well.

Does it fit my road bike?

Yes, it suits almost all bicycle frames up to 6.5cm. Recyclable mounting straps are supplied so the lock can be attached to the frame or seat post in several positions, making it easy to carry.

How quickly can I secure my bike?

Speed is the purpose of the folding mechanism. Once you reach your destination, you can deploy it and lock up in about 3 seconds, making it the quickest option for a short stop at the shops or a commute.

Can two bikes be secured together?

Yes! Fully extended, it is long enough to tie two bikes to a single fixed post, so families or couples who ride together will find it ideal.

What's the return policy?

Every UK cyclist deserves to feel secure.
