WOWSPORT Bike U Lock with Cable, Heavy Duty 19mm Anti‑Theft D Lock
Both Ends Locked, So Both Sides Must Be Cut
- Both Ends Locked, So Both Sides Must Be Cut — The shackle locks into the body at both ends. A thief has to cut through each side separately before the lock opens: double the time and double the noise of a single-lock design. A 19mm alloy steel shackle with a full silicone sleeve over the bar.
- Silicone Sleeve Protects Your Frame And Rims — The whole shackle is wrapped in a soft silicone cover, so the lock cannot scratch your frame, rims or paint while it is fitted, carried, or rattling on the move. The smooth cover also gives you a comfortable grip when you carry it.
- Copper Core With Serrated Double-Groove Keys — A copper lock cylinder paired with dual-groove serrated keys, which are harder to pick or bump than a plain flat key. Two keys included - keep one on your everyday ring and one in your bag as a spare.
- 120Cm Steel Cable Adds Reach — The included 12mm braided steel cable loops through a second wheel, a second bike, a helmet or a rack, so you are not limited to what the shackle alone can reach. Use the U-lock as the anchor and the cable as the extension.
- Compact To Carry, Mount Bracket Included — The lock body measures about 20 x 12.2cm and weighs about 1160g, small enough for a backpack or pannier. A mount bracket is included so you can carry it on the frame instead of in your bag. Also suits e-bikes, scooters, gates and ladders.

Frequently Asked Questions
Fitment, maintenance and shipping — the questions we answer most often for this product.
What is the WOWSPORT Bike U Lock with Cable, Heavy Duty 19mm Anti-Theft D Lock designed for?
Both Ends Locked, So Both Sides Must Be Cut — The shackle locks into the body at both ends. A thief has to cut through each side separately before the lock opens: double the…
Which bike lock is hardest to cut?
A U-lock with a 19mm hardened steel shackle. Both ends lock into the body, so an angle grinder or bolt cutter has to defeat two points instead of one, and the shackle cannot be twisted against the ground the way a chain can.
How long should a bike lock be?
65cm suits a frame plus a fixed rack. 100 to 103cm is the all-rounder: frame, one wheel and a post with a little slack. 120cm is for two bikes, or a thick post plus both wheels. Length costs weight and money, so buy for where you actually park.
Can a cable lock be cut?
Yes. A braided steel cable stops someone walking off with an unlocked bike, not someone with cable cutters and thirty seconds. Treat a cable as a second lock that secures the wheels, and use a U-lock or chain as the primary lock on the frame.
What if I forget my combination?
There is no master key and no recovery code, by design — a master key would open every lock we sell. A locksmith can cut the cable or chain, but the lock will not survive it. Set the code somewhere you will find it that is not your phone.
Will a U-lock scratch my frame?
Our U-lock ships with a full silicone sleeve over the shackle, and the cable is PVC coated, so the parts that touch the frame are soft. The bracket mounts to the frame with rubber shims. Any lock will mark paint if it is rattled around loose, which is why the bracket matters more than the coating.
