I've built hundreds of hub motor wheels and it STILL takes a long time. The only way I saved some time was to use a power drill to install the nipples to an almost tight position :lol:
If this keeps up, I may end up like others here with an assortment of wheels and tires cluttering up the bedroom!
Women love that!
At 95 volts, an 18" x 2.5 will see almost 50 mph and will still give me my target 38 mph cruise speed on my 2 lane, 40 mph country roads.
But by what JRH just said, it sounds like aluminum motorcycle wheels like the Prowheel 36 hole are almost too much hassle to mount a hub motor properly to. Certainly more labor intensive. Something like this:

Or buy a 22" BMX rim, drill out the holes slightly for 12g, lightweight, easy build and tough?
richdeloup said:Well, I doubt if a 22" BMX rim is as sturdy as an ally scooter type, however I've found that they do fit 18" motorbike/scooter tyres perfectly.
They are 36 hole, double wall construction and pretty industrial strength, as meant for taking huge jump impacts.
I'm not talking about using 22" bike tyres, although the F22 bmx tyre is amazing, built to take 100psi and is 2.29" width.
So there is a fairly large range of tread patterns etc. Easy to build onto any bicycle hub as they are a bike rim.
This pic show a 3" wide tyre which is the maximum the rims will take. Ive also fitted a 2.5" and a 2.25" with no problems.
I can supply these rims in the UK and Europe, however anyone nearer the US would be able to buy basically the same from S&M bikes.
I have a load of other pics of various other tyres but am away from my personal pc until tomorrow when ill try to upload them.

They fit in theory, i.e 20inch bike wheels take 16inch motorbike tyres, so its pretty logical stuff that 22inch bike wheels will take an 18inch Motorbike/scooter tyre.

Do you think 18" M/B rims are probably still the way to go if using fat hub motors?
Here's a pic of another 22" rim (completely different manufacturer) with a 2.25 scooter tyre, showing bead fitment. This set up is cheap, however 2.25 is the max this rim will take.
Could be good for narrow hub motors/lightweight builds?
