A very good idea.

You could use one of these with some sillsons/adjustable spanner/water pump pliers:

I tried all that and what Sturmey said, with a lot of help from Thor's 1.6kg lump hammer. If it would be that easy, it would be done. If you remember, the last Argos folder I did had the same problem, and I successfully got it off using those methods. It's extremely difficult to hold a stilson or monkey wrench onto the thin metal while you try to turn it, and the metal is starting to distort. That's why I need a tool that's 100% the right shape:

That tool is pretty cheap.

I have had some bad experience with cheap tools which are supposed to remove tight things like you are describing. I had a problem on my old car with a windscreen wiper mechanism and the repair required that I pull the wiper arm off a taper. I bought a universal wiper arm puller and it broke first use. I worked out a way to get it off with old motorbike tyre levers and that worked. There were other failures too. One was a crank arm puller that stripped the threads on the arm and caused me to abandon the task. I gave the bike away to a ragamuffin.

Yeah, I think it's a very satisfying feeling having exactly the right tool for the job. But what a stupid design of a bottom bracket.

But I would still like to hear you've tried to fit the motor wheel with a 9 speed cassette fitted.

My plan is that tool and a bit of heat. If it doesn't work, I'll weld a 3 foot bar to it directly. If that doesn't work, it'll be chucked in a skip.

Been there, done that. I will now only ever use a Park Tool crank arm puller.

Amaxon - Bike Bottle Holder Mount Adapter

These are worth a try - rubber coated with rubber straps


Thanks everybody for ideas. I think some of those things are OK if you're scared to drill. personally, I wouldn't be happy to have a 3.5kg battery held on by any of those bodge methods. 20 mins work and two 5 pence rivnuts got me this. Now I have three strong rivnuts to fix the battery base to:
