Dynamo Lights

Megashim! Megashim! Megashim!

Multipack coke can shim

Ha, I would shim but its actually not possible. Once you come to fit it, you realise its an awful design where you have to clear your bars of everything and slide it on from the end - a two part clamp like an out front garmin mount would be so much better.

TL;DR can't shim cos I can't slide it on the tubing.

Pretty sure this another light model, but nicely done.

Better option is probably to lose the mount altogether. Looks like the bar mount is bolted on. Undo that and replace with a flattened pipe or piece of sheet metal

People on here have made little clampy things out of an old film canister that is approximately handlebar diameter. I think maybe @spotter did it?

Edit: @mashton did it also

I would try to bodge something like that onto your rack somehow.

This is my thought - bolt is rounded off (possibly made of cheese) so will require a bit of work, but yes this is good thinking.

Best bet is probably attaching to rack strut like above, meaning a can slide something on. Some kind of sleeve over rack strut with an arm which then fixes to the bolt.

Hmm, a little more 'agricultural' than I was hoping for, but yeah it is an option.

P clip no?

I made mine by from a piece of steerer cut off. Popped a star nut in to get some to thread a bolt through and put some inner tube over the outside to make it grippy.

If you can CNC/machine stuff I'm sure you could make a much neater thing that does the same job.

Of course, P clip is so obvious. Great shout.

A colleague has made a light mount in work on his 3d printer so will take advice from him first too.

Oh, wow! Slow off the mark. That's got to be up there in the top 10 bodges of all times!

Update - Took a second look at the toolbox through the lens of just a bolt attachment, then took another look at the rack mountings. Realised that all I needed was a right angle, and I could hang the light off one of the bolts going through the bed of the rack.

Never throw away the mudguard mounting spares, that's all I'm saying.

Sorry - dark photos that I can't be bothered to edit this moment.

Nice! Very neat!

Nice work.

Thanks, surprised how simply it came together in the end

I'm honoured.

I'm considering setting up a dynamo system but I'm wondering if they're liable to be stolen if left on the bike when it's locked up. I remove my battery lights when locking my bike at the moment but it looks like that might not be so straightforward with dynamo lights?

dude, dynamo lights are connected via cable, and usually bolted to frame/rack. Lots of faff to steal, and as far as I'm aware no one has had them taken, at least in this thread.
Dynamo lights are fit and forget. If your bike is there when you return after locking it, your lights will be there..

It is a worry that one day some thieving gets will realise just how much cash we're all spunking on dynamo lights. I would imagine, like mudguards used to be, that in the perception of your average parts stripping thief, bikes that have bolted-on lights must be some kind of old-fashioned rubbish and not worth looking at. Let's hope so anyway.

If you're really concerned, and I don't blame you on that, you could maybe fit it to the mounting using a pitlock.

Or a shitload of threadlock just to make it at least difficult to remove.

ok, good to know. I might make it look crap with sellotape or paint etc

A nutted axle or locking skewer is a good idea.

Lots of faff to steal

Taking the wheel is no harder than a non-dynamo wheel.

Was responding to original posters question about loss of lights, and removal of them.
On wheels, none of the dynamo hubs I’ve got are quick release which automatically is making it more of a faff for whoever wants to steal them.

Anyone tried these:

They do some pretty cheap lights which seem well made
