One of the main reasons for this purchase was a combination lock dont like to carry keys around

I appreciated that the lock was based on numbers rather than a key because if i lost the key which i most likely would i wouldnt be able to get my bike back

All i can say is that ive been using this for two months now and the bike hasnt been stolen

My bike unfortunately was stolen at the campus a while back by thieves who cut through my cable lock

The shackle is too short to lock the frame of my bike to the wheel and too short to lock two bikes together on my rack because there is a gap of a few inches between them

Also no means to mount it on bike while riding

A little big but it does the trick just a little difficult to ride the bike while the lock is resting on the bike

I suspect that the 4digit model would also be sufficient for most cyclists
