3.1FT Heavy Duty Chain Lock - 10mm/0.42inch Thick Bike Chain with 16mm/0.64inch Disc Lock for Motorcycles, Scooters, Gates and More, Blue

This product is in a good quality and brings safe to my electric bike

It took me a few tries but this lock fits perfectly around the main tube of a Seqway Ninebot Max. The actual lock is darn near a perfect fit, so much so that it was tricky figuring out how to get the actual chain locked too. The trick seems to be fitting the lock and chain higher up on the tube and not at the base. It's a tight fit, but it was exactly what I was after.Oh yea, this thing weighs a good bit and the locking mechanism seems to be fairly consistant. Not for those loooking to save weight. My wife has a sit down scooter with basket in the back so that's where this will be going. Might be too heavy for solo rides. We will see...

I unfortunately lost my brand new beach cruiser because I WAS NOT using a lock like this. My boyfriend so kindly got me a new bike and so I wanted to invest in a better lock. I purchased this lock and I am really happy with it. Its very sturdy and heavy duty. Its pretty heavy and makes a lot of noise which makes me happy that if someone does try to snap it they will have a hard time doing so. So far I've had this lock and my bike has not been stolen so its great!

Im buying this just for the chain. Those locks might be fine in an average community, but bike theft is huge where i live. And i ride my bike everywhere so naturally i have a good reliable bike. Two of my bikes have been stolen with locks like these, and many other locks that are reported to be the best are no match for the thieves out here. The only lock they havent yet broken is an ABUS lock. Paired with this chain, should be unstealable

I use 2 of these chains to lock up my $1500 electric bike in downtown Cincinnati overnight. So far no one has stolen it or attempted to so I guess it’s working. I thought it was a good price for both a chain and u bolt style lock. I seen other brands sell the chain alone for the same price.

We had some attempted mc thefts recently, at the time my bike wasn't locked up, as a result they tried to hot wire my bike even tho the fork lock was engaged and the keys got an rfid system that requires the right tagIt cost me 700 to get it moved to a mechanic and get it fixed.This lock is so big and solid and visible it immediately becomes way less appetizing to idiot would be thieves.The key is complex and the whole thing weighs something around 7 or 8 lbs. The shackle is huge, chain long enough I can easily wrap it around the park structure.I wish I'd had this year's ago

I had a 3/8" $30 steel wire lock on my bike, I thought it was hard to break. One day the lock didn't open and I had to use a grinder to cut the wire... It was soooooo easy to break it. That night I ordered this chain, it looks sturdy, it's heavy (8 lbs) and I know it's difficult to cut. I know my bike is secured

Lock worked perfectly until today locking mechanism is not working i can not get lock off my bike i cannot get in contact with seller i paid 50 dollars for a lock just for it to stop working after 4 months use
