Ouch! bad design.

I plan to fit a Rolling jackass on my dummy, and wondered if it were possible to rig it with a lock? I had been thinking to do something myself, when I got one, but given my budget, and my procrastinating tendencies, that might be a while. So I suggest it here to see if anyone can come up with something? Val, are you listening? Feel free to ship me a sample for testing!

I got an AXA lock and a cable today. It will work on the back of the fork. I have to figure out a way to mount it. I don't think the supplied straps are long enough to mount to the fork. I think the cable I got is long enough to go through the frame and around a rack or post so even if I had to resort to cable ties to hold the lock to the fork it would be pretty secure with the cable.

I mounted the lock on the fork with cable ties. I may do something different in the future. The cable is long enough to go through the frame and wheel and around a post or rack.

I don't know how I feel about the fork mounting. You can just cut that cable and drop the front wheel, and the bike is yours. The reason for back triangle mounting is that even if the lock is dismounted, it cant leave the seatstays.

Off topic, love your pedals. I have the same pedals, and I won't be changing them until they are dust.

I really like the lock on my fork. I added lots of heavy cable ties and I'm going to leave it at that. My previous lock was a heavy combination lock with a cable. It was not convenient and less secure than the AXA with the cable. If I'm making a quick stop I just pull the key, if I'm going to be awhile I'll use the cable.
My bike weights a good 110 pounds. The rear wheel locks electrically with the motor. Yes, someone could cut my cable ties and fight the lock past the fender and drag 90 pounds of bike with the rear wheel sliding to a waiting truck. Then they just need to steal two wheels to use it. If someone wants your (enter item name here) it doesn't matter what it's locked to or locked with.

You allmost always find a so called "ring lock" or a similar lock on a bike bought here in Sweden. They are integrated from the start. Good as a complement for my U-lock!

Thing is on the rear , even if you take the lock off the frame,
being on the inside face of chainstays, Ring is still captive in the rear triangle

How? Unless it's bigger than the dropout spacing it can still come out there.

If it's mounted in the rear triangle you couldn't just drop the rear wheel out. The lock wouldn't fit through the frame if it's locked to the wheel, at least that's my understanding.

We have 3 different ring lock types in our bikes. The idea is the same as with Sheldon's u-lock method: rear wheel with a ring lock cannot be removed from the rear triangle, unless you cut through something (triangle, rim or lock).

This is the type of lock I use on my bike. It is always attached to the bike and has an alarm built in should anyone try cutting the wire.

I got mine from ebay, you can pick one up pretty cheap.

I spent a lot of money on my bike and the last thing I want is some bugger nicking it.



Here you can see the cable looped through my front spokes and around my fence. I also just bought a motion alarm padlock that I put through the front disc brakes n' spokes - (hard to see in this pic).

There are pinlocks out there that you would be able to use if it was mounted on the head tube with it's receiver on either the lower fork or stem. Think of one of those sliding pinlocks. That should be a simple mount. I'd weld it on both.

Thin or small frame locks can come through the triangle. Am I the only one who finds it amusing that these things are ziptied on?

When I first saw a ziptied lock (this was years before I heard of Sheldon's locking method) I definitely went "wut." All my earlier locks were welded on, so it took some time for me to figure out the lock isn't going anywhere even if the zipties are cut.

I have a U-lock that spends the week on the rack at work unless I know I'll spending time somewhere with high theft potential where I can't see my bike. That way I don't have the problem I used to have of riding my secondary bike to work and realizing that I forgot to grab the lock off of my main ride. The rest of the time I carry an OnGuard looped cable and feed one end into my ring lock after looping the other end around something stationary and through the front tire. It still requires me to carry something, but it provides enough security for me for 90% of my riding.

Metal man may consider a pair of steel P clips , around the fork blades ,
and bolting thru' the mount holes on the lock , get them good and tight,

but since the V brake bosses are there , the wheel wont slide out even if P clamps got loose..

lots better than the plastic Zip-ties.

I thought the same, I tried a thick handcuff about the size of a pinlock (masterlock street cuff). All a thief has to do is let the air out of the tires and that lets the lock twist enough to get it out of the rear triangle......

But then again it is not a theft prevention item, it's to stop the guy from casually jumping on it and riding away. If he tries he'll break some spokes and then will screw you up just as much if you're far from home.
