    • Solid lightweight U-Lock
Style: Lite_mini
This is a good lightweight U-Lock. It's not perfect, but it's pretty good. A few notes. - The "LITE" label seems very silly. Why advertise that it's lightweight. Luckily this came off instantly with a tiny bit of acetone / nail polish remover. - This is on the small side of U-locks. I've found that I can generally lock to most things by going around my rim and tire through the rear triangle and to a solid object (Sheldon Brown's method) with my large 55mm wide tires, but on some objects it's a bit awkward. If I just go around my steel frame tube, then I can lock to many things easier. - My wide tires (55mm wide) press the two legs of the "U" apart when I put it over the tire and it is difficult to install the crossbar. Once I figured this out, it is not a big deal and I can gently squeeze the legs back together with my hand to install the crossbar. But it was very frustrating before I figured this out and I just couldn't get the crossbar on. ... show more

    • Still going strong after 4 years, and has never let me down. Ignore the other reviews.
Style: Standard
I bought this lock when I first got my ebike, and came back to write a review after 4 years and was shocked to see all these 1-star reviews with people that can't seem to get their heads around: a) the limits of ANY U-lock (such as the fact it's rigid and thus not great for things like power poles) b) How to unlock the lock (hint: you push the key all the way in, and turn it) c) All bike locks are deterrents. If you park your bike in a dodgy place, or if someone *really* wants your bike, no lock will stop an angle grinder. At least this one will make it a pain in the ass. With those things in mind, here's a brief pro/cons on this lock after 4 years of use and 6000km of commuting on my bike. I haven't babied it, I've thrown it around and used it like a lock. It's been on the back of my rack all the time, and I've locked it up in some pretty sketchy places to find it always back and working, in the pouring rain, sleet and overnight. The key and locking system are still buttery smooth after 4 years, and although it's beaten up there is physically nothing wrong with it. PROS: + Beefy security. It's heavy and hefty and a great deterrent. I've come back to see obvious scratches where people have tried to pick the lock, hack at it with some kind of saw and generally try to bend it (which left marks on my frame). I still have my bike 4 years later. I think the other reviews made the mistake of either parking their bikes not next to other bikes (always a good chance the bike next to you will be easier), or expecting this to stop a blowtorch and last for eternity. Locks are deterrents! + Durability. I have locked my bike in and out of cover, under tarps and in the open rain for weeks on end. I also live near the sea, so I do get a bit more corrosion (I've been through two chains on my bike, for context). No issues with any part of the lock at all, including the key/locking system. + Length - no, it won't wrap around telephone poles like a folding lock can. But as long as you understand that, it's a great size and length for most poles, bike racks and metal fences. It can be annoying give it isn't a folding/cable lock, but again the U-locks will be more secure than the former. CONS: - Hefty - this lock is a chonk. It's hefty and the frame mount is crap, so it has to live on my back rack. Honestly it doesn't bother me since I prefer the security but it does have to be said. - It's a U-lock - which means that it is rigid and it can't wrap around or through objects. I personally commute around the city where there are plenty of bike racks, metal fences or narrow sign poles for me to lock this up to. If you don't have that luxury, then get a chain or folding lock. - Key system was fiddly on first use: I remember when I first got this lock and I accidentally seized up the lock trying to unlock it. Turns out, it's really easy to half unlock the lock if you don't push the key all the way in *before* turning it. After a few months I got used to it, and I haven't had ANY of the durability issues I've seen from others in the past 4 years. I've always made sure to close the keyhole protector, and push the key all the way in before turning. No issues, but it was a slight curve - Not indestructible - All the photos and 1-star reviews I see are from people whose locks were cut through with an angle grinder or a very, very determined thief and a metal saw. Nothing will stop a determined thief. It's common logic to try and park in a very public, well-lit place, preferably next to some other bikes with crappier locks that are easier to steal. Thiefs are opportunistic, and so if the nice bike next to you has a shitty lock that takes less time to steal, they'll take it. I totally get it, people are mad that their bikes are stolen, I would be too. But that isn't the lock's fault - if you want a near-indestructible lock, get the NYC Kryptonite lock and carry an extra tonne of metal around, or get a frame lock too and multiple U-locks. For me, I just park in a sensible spot, locked to something metal and with the frame lock in my bike too. I've had several attempts on the bike, but no one got even CLOSE to cracking it. Remember kids, angle grinders aren't subtle or quiet. But if you park in a place with no one else around you, it will be. ... show more

    • Great lock
Style: Mini_7_w_cable
Review Image by JCark JCark
We have high hopes for this lock. Unlocking and locking started out as a challenge but once we got used to it/figured it out, all is well. The steel cable is too short for beginners to maneuver. Especially if your beginner is a teenager. Bike has yet to be stole, so we’re doing good.

    • Would be 5 if not for…
Style: Mini_7_w_cable
The location of the mounting bracket on the U lock make it difficult to place this in an easy to use location. Would be nicer if it was rotated 90 degrees so it could be side mounted instead of the way it is.

    • Seems like a nice bike lock
Style: Mini_7_w_cable
Seems like a nice bike lock. Only time will tell if it truly is a secure one. For now, it's good for removing temptation and keeping honest people honest. LOL! I had a higher end model son my last eBike but it weighed a ton so I opted for this smaller one. Fingers crossed it was not a mistake.

    • Useless for fat tire bikes
Style: Mini_7_w_cable
If you own a fat tire bike, read the specs carefully and confirm the lock will fit around a rear tire and the frame. I didn't and it's pretty well useless, except as a lock for a cable. My bad. The lock itself is Kryptonite quality.

    • Solid but heavy
Style: Mini_7_w_cable
Hard to add much to the extensive reviews for the product. Seems solidly made and locks smoothly enough. Very heavy but there's probably nothing the manufacturer can do about that while preserving the security features.

    • Nice finish
Style: Mini_7_w_cable
Great size (not bulky) and good rubber cover. The size is great and it also has a cover to avoid any water entering the lock when the key is inserted
