Long enough, good thickness, if they really want your bike, the will get it. This ia a good deterrent in a well watched area, great for a quick lock up outside a coffee shop, with eyes watching .
The cable is a little thicker than the average cable lock. The mount is handy and I particularly like the velcro strap that keeps the loops together when it is mounted on the bike.
I use it for locking up a beach cruiser. Can go around a variety of objects for locking the bike up easily. Fits on the handlebars when riding to the beach or around town.
Coils small,mounts w adapter on frame.Seems really strong for a frame lock-up.
Ive used this lock for several months now. heavy duty and easy to use. it coils up around the top tube of my bike when I'm not using. I would recommend if you need a bike lock.
With its coil up style it fits well under the seat or on the down tube with the clamp that comes with it. This lock may not stand up to the pro theives out there but it will keep your bike safe for short term stops and high traffic areas.
