  • Great product!!!!
Color: Black
IF YOU HAVE A E-BIKE or ANY BIKE, GET THIS LOCK!!!! Easy to use, wasn’t worrying about someone cutting into it and it has a strong hold.

  • Sturdy and compact
Color: Black
Bought two of these for two new mopeds. My partner and I were a little nervous, as we had previously had two bike locks cut and bikes stolen. Not sure if anyone has tried to cut these yet, but they are still intact - which is a win! It’s been about 6 months and these have held up great. The chain portion is also long enough to help navigate any weird parking situations. The best part: it’s compact enough to fit inside our mopeds’ little seat trunks! ... show more

  • Key hard to fit
Color: Black
Great product, durable, only probably is the key is hard to fit in the lock takes some finagling, other than that super big and fits the whole frame of the bike around the railing. Chain is heavy and durable and able to wrap my back tire to the frame.
