They need to nip this kind of wheel hanger design in the bud. The better way is to have an arm that grabs the saddle and pushes the bike against the tray

Oh wow I love that! Need more in the city. Although "Exclusively for everyone" is kind of funny.

To circle back to the thread title, which no one seems to have addressed: you don't even need an angle grinder to defeat a U-Lock; I've cut through one with a hacksaw (5 mins, lots of sweating) and with a very long bolt cutter (10 seconds, lots of muscle).

I’ve been locking bikes on the mean streets of Philly and Pittsburgh with a u lock for over 40 years. And I’m not talking beaters. Never had a bike stolen. What am I doing wrong, or right?

And they don't work with fully faired recumbents, either! WTF??!!???

For those, just go to a pawn shop and pawn it for $30, you can leave it for a month and they store it safely for you. My favorite pawn shop only charges $5 on the pawn.

Store a bike for a month for $5.00. You're welcome...

your lock is cooler than your bike

I bought this lock in 1977 and used it to lock various bikes for the next ~30 years. YMMV.

so that explains why you have so many bikes.

Ha ha! No.

I used to run a bike rental program on a college campus, and occasionally a student would lose the keys for the U-Locks we provided.

Looks like you'd catch tetanus from that. Good theft deterrence!

I have that exact model sitting in my garage, never used. Bought it in 1998 for a tandem trip to Italy. Probably should donate it to a local charity. The thing probably weighs 5 lbs.
