NDakter Bike Locks Heavy Duty Anti Theft 18mm Thick, Motorcycle U Lock with 4FT x 6mm Moped Chain, 3Keys Large U-Shape Electric Bicycle Wheel Lock for Ebike, Escooter, Fat-Tire Dirt-Bike, Tricycle

Very sturdy and secure, no complaints. I love that it comes with 3 keys and the fact that it's big enough for my fat tire e bike. The chain is a plus too.

This lock is secure and easy to use. I use it to secure my mobility scooter. It has weight to it, giving it the stability it needs to keep my scooter in place. Fits perfectly around the wheel spokes and is very durable.

All I can say is this is an outstanding bicycle lock for our e-bikes.

very strong, functional bike lock that can fit around a frame has been very helpful.

Sturdy enough, hopefully it won’t ever be tested. Chain seems a little skinny but the U shaped wheel lock seems very thick and durable. If you have a bigger CC bike you’ll only be able to install it around the front wheel, my rear wheel was too wide and it’s a 600

Good lock, arrived fast, so far so good.

this works fantastic for my motorcycle..very secure fit..love it..

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!
