Best For electric Bike: Joytutus U shaped Lock

Buy on Amazon

We would, of course, be remiss if we didn't mention joytutus u shaped lock for regular usage. This lock set that is made for a reputable manufacturer (Joytutus) is well made and will do a good job in helping to prevent theft or at least discouraging a thief from targeting your bike. It slides down the frame, the lock jiggles and wobbles on the frame. It works well when holding it level right in front of you, but when reaching to lock the bike through a rack etc., the dial seems to jam. It is easy to throw around anything.

The lock itself looks solid built with good quality material. The cable is plenty long to reach from the hitch to around the frame and/or through a wheel. It’s easy to also store it on your bike without taking up too much space. The combo slides can be a little tough to spin.
