As well as being the ultimate in bike security, Abus locks are always designed with ease of use and thoughtful design – after all, no matter how strong a lock is, you’re less likely to use it at all if it’s a fiddle.

Whilst not as portable as a u-lock or a disc lock, for a leave-at-home or leave-at-work security devise you can’t go wrong – if you park in the same spot with any frequency, thieves know where to go to find your bike, so an Abus chain is a good idea if you want them to leave your bike and try their chance elsewhere.

Covering a whole range of bike security devices from high-quality U-shackle locks to lock-chain-combinations, steel-o-flex to frame locks; Abus has you covered for every situation.

Abus locks are tested and acknowledged by independent experts in numerous countries, including Thatcham and Sold Secure in the UK.

Great all year round jacket
Had this jacket through the year, differing weathers and conditions. The removable layers help to prepare for all situations, whilst still providing great protection and comfort.

Awesome jacket, bone dry and comfortable
This is the best motorcycle jacket and trouser I have ever owned and I’ve had a few, some of which cost 3 times more then this! It’s super comfortable on both my touring and sports bike. You can’t go wrong.
