If you use a bike for transport, securing it when you park it can be a problem. A length of chain and a padlock might do the trick, but an enterprising thief, with a set of bolt cutters in his back pack could take off with your bike in seconds flat.
The problem with bike locks, they are big and bulky, or if they are small and compact, then often they do not have the capacity to go around a stationary object like a bike rack or fence, and secure the frame and both wheels.
It was the reason the design of this lock pictured above had me taking a second look.
It folds up small when not in use, and when opened up its effective length is 32 inches. (81.3 cm.) Made up of 6 separate flat steel bars, jointed by rivets, the device folds up to measure 7 ¼ in. x 2 1/8 in x 1 ¼ in. (18.4cm. x 5.4cm. x 3.4cm.)
There is a built in lock, with what the makers call a “Class B” key, (See picture left.) making the lock difficult to open by usual lock picking methods.
In order to try the lock out and to take these pictures, I secured my bike to a nearby chain link fence.
The flat steel bars threaded easily through the wire fencing, and around the steel fence post.
I removed my front wheel and placed it alongside the rear wheel.
There was ample length to go around the fence post, frame and both wheels. (See picture below.)
The steel bars have a heavy duty powder coat, and are nicely rounded at the edges so they won’t scratch your paint. The rivets too are countersunk below the surface so they won’t scratch and also making them difficult to file or grind off.
Where the flat bars are riveted together, there is a loose washer in between, which would simply spin if any attempt was made to hacksaw through the rivets.
The lock fits neatly into a carrying case when not in use.
This is supplied with the lock and attaches to a set of standard water bottle mounts.
If you can’t afford to lose a water bottle, you could carry it in your back pack.
It would be too heavy for a jersey pocket. Weighing in at 1lb. 10oz. the weight is the one drawback.
But I don’t see a way round this. If a lock is to be effective as a theft deterrent, it has to be strong.
If this lock was made lighter by using less metal, it would be no better that a length of chain, and vulnerable to bolt cutters.
The lock comes with 3 separate keys.
