  • Nice. Could be a little longer
Size: SHORT
This is a nice lock and chain. My wife recently purchased a $3500 electric trike and we really don't want it stolen. I would like the chain to be a few feet longer in order to have more choices how to secure the trike. She recently took the trike to a store. There was nothing to lock the trike to. What she did was lock the basket on the front to the front tire. At least with that the front tire won't spin. If the cable was longer she could lock two of the three tires together to make it more difficult to push away. Overall I'm very happy the the lock and chain. It appears well built and I especially like the cover over the chain. It helps prevent scratching of the paint. I would purchase again. ... show more

  • Lots of options with this large lock and mounting kit.
Size: Long
Review for NDakter Motorcycle Locks Anti Theft, Heavy Duty Bike U Lock with 4FT Chain and Bracket,15mm Shackle Electric Bicycle Lock for Scooter, 3 Keys Motorcycle Wheel Lock for Ebike, Moped, Tricycle I like this lets me hook into a rim and the body and chain around something. I'm using this for a bicycle and just want to deter thieves at this price point. If I could I'd get one like this that has a coating to make cutting it take longer but what I'm securing isn't that expensive and isn't going to be out of my sight for that long. I prefer a chain like this, but I'd rather have a thicker one, to coated steel cables, really wish the chain was thicker. ... show more

  • good for layered security but has no third party security validations
Size: Long
Seems to be a heavy, sturdy, reasonably well made lock. Nice that it comes with an added chain. The fact that the lock comes with no added security validations like Sold Secure or ART makes me unwilling to rely upon it as a sole security mechanism. As an additional layer(s) of security to more tested and validated solutions, I think this lock only enhances the protection you'd get there. ... show more
