Please recommend a way to do this. Where can you buy mounts or clamps that will hold a heavy U lock to the side of one's rear rack? Or is there another option? Ease of mounting/removing the lock and secure mounting of lock obviously important. Thanks.

If it's not in my panniers or trunk bag, I just lock mine around the head tube. Secure, and no fussy mounting clamps.

TwoFish Lock Blocks will mount to pretty much any part of a bike frame. I'm not sure about your rack, though.

+1. The velcro tie-down is a nice touch.

That looks excellent. I emailed'em to find out where to buy their products. Thanks.

I'd love to see a photo of how you do that. Thank you.

That's a great way for times without a trunk bag. Thanks.

Tidiest is the right rack, Tubus Locc, and the Abus U lock,
that it was designed to carry , on the inside of the left leg,

so quickly removed, to deploy, even when panniers,
and top of rack are packed.

I do the same everyday, but skip the velcro. It makes some noise over bumps but no big deal.

I have a cheap lock and renters insurance. 60 dollars a year so I don't have to cram a rack on my bike for a lock that sucks. I hate U locks...

This is how I do it, I found a small laptop bag at a thrift store for two dollars and lashed it down with a couple of leather straps (milsurp I had laying around) with a little (probably unnecessary) assistance from one of my bungee nets:



The other leather strap is hidden by the bag behind where my Road Morph pump is poking out of the top of the outer pocket.

My girlfriend is no fan of used things and often raises her eyebrows to some of my solutions to things, but in this case she actually expressed that she was envious of this one and that it looked like it had been specifically designed for what I was using it for! I love that my lock makes no noise and is quick and easy to stow now (it's in the zipper pocket along the top). Of course when I need to run two panniers I need to pull this off, but that takes just a minute to unbuckle the two straps and I slip the lock (& pump & bungees) into the back of an Ortlieb.

I stow my bungees and my other bungee net in the outer pocket (under the webbing), and when I go on tour, I remount this bag outboard my starboard side bucket. It also gives me another accessible pocket.

Most days I run this, and an Ortlieb on the other side with my work clothes, toiletry bag, and lunch in it.

The reply from TwoFish said their Lock Blocks for U locks are designed only for use on the handlebar.

Yo también. However, I actually prefer the noise; half the time it gets people ahead of me to move over to the right without me having to ring my bell or shout "On your left!"

Bicycles can be pretty scary on MUPs if they're completely silent, so I get to kill two birds with one stone with this solution.

I often throw my lock in the rack like this (with a velcro strap) but usually put the lock through the tie down straps on my panniers.

Secure a bunjee chord across the top of the rack.
Put the lock under the bungee chord.
Jamb the curved end of the shackle under the raised front loop of your rack.
If you rack has a solid top plate and no open loop (as in Medic Zero's rack) then change it for one that does.
This fitting is totally secure with no rattling, provides instant access to the lock for locking or anything else and does not interfere with bags. You do have to lock before removing bags and attach bags before stowing lock, but this is the natural order of things.

I placed my U lock inverted from the way you have it, with the curved part of the lock resting on one of the cross bars of the rack. Then used your idea and placed velcro straps at two points to keep the lock attached to the inside of. my rack and away from my fender stays. And this leaves room for placement of my Ortlieb waterproof panniers. Thank you!

Look at their Bikeblock or Megablock. I use the Bikeblock for my U-locks without any problem. I have attached them to the top tube and the seat tube. I don't know how well they will work on a rack though. You might be able to connect a portion of seatpost or PVC to the rack, then the Bikeblock to that.

I have small bikes, so often the U-lock won't fit inside the triangle if I have a water bottle. What I do is place the Bikeblock on the seat tube with the U-lock facing backwards, resting on the seat stay. I then velcro the lock to the stay. It's kind of difficult to place it correctly, but once done, it stays in place and no foot interference.

I tried that, but even with the velcro it jumped around too much for my taste (roads here aren't what I'd call good). Now I just put it on top of my rack and use a bungee cargo net to strap it down. I've got Wald folding baskets bolted to the sides of my racks so lots of places for the net to hook.

I'd be curious to hear recommendations of racks as sturdy as the Jannd Expedition that like it, minimize heel-strike issues.

How long does it take to secure like that? Seems like it would be cumbersome and annoying to do.

[QUOTE=Medic Zero;13367759]The bags come off with a pull of the handle. Then maybe 10 seconds. Easy peasy.

Both Trelock and Abus make mounts for racks. I use the Trelock ones, and am very happy with them.
