No doubt I might have missed one, but so far I've only seen one RC motor setup that worked and that was Thud's race bike that used a 2 speed transmission in order to match the RC's motor strengths. It only had to survive a few laps too (which Thud's failed to do).
I would be very worried about heat as they don't have much thermomass. Maybe with water cooling like the big RC boats use. Not a lot of air goes past at bicycle speeds either.

any idea on what this is, with the transmission and all. says he messed around with astro motors and yachiting motors, but decided on a motor thats only ip54, although the transmission is ip67. The bafangs seem more waterproof, driving thru swamps and all lol. but a yachting motor could be sweet. Whole system is only 7lb but also requires a special rear hub. I thought about buying this bike actually but its like 5,500$ and might not support schwalbe MPlus 24x1.75 with the custom hubs and all, runs 24x3, guy never really replied to me or w/e
As far as a brompton goes, are there any ultra narrow 750w+ rear hub motors that would fit within a narrow triangle or even modified
theres a couple of rear 250w systems, the former requires a whole new rear triangle, this boost one is like 36v 250w and maybe has a proprietary BS battery and isnt out yet so no torture testing. 2,500$ and 600$
putting a good 750w+ into the rear wheel without having all that hub wheel weight would be so fun
maybe some alibaba chaps could make a scaled down clone system and hubs to fit different bikes, i guess the chimera system as-is requires a custom frame space mount but im sure that could be worked around with a smaller motor and transmission. the chimera is like 1000w minimum 3800w max and has pretty terrible range. but it does do backflips!
Are you forgetting (our old friend now passed), Ozzie Jesters self built cruiser with the big Turnigy 80100 ?
got a link?
the brompton seems like the safest option for gettin' rad but i've tried their 250w front hub motor and it's ass , literally broke down on me as it has with tons of people. maybe the GRIN saw20 500w is better. They said it only does 52v but i think theres an adapter that lets you run it with their 72v controller up to 800-900w. But front motors are goofy, Sadly the Saw20 has no rear hub option, although they said maybe a mount on it could be adapted to run rear hub. Not sure if it would even fit the standard triangle.
i guess some adapters exist or DIY is possible
Converting a front hub motor to a rear?
i just shot an email to Crystalyte too

Some aftermarket kit promos. (Hey people are paying 2500$ for new titanium rear triangle to shoehorn in a crappy 250w Internal battery hub)
