Anyone tried one of these??

I’m jumping the gun here as I know I need to update my last build, and I will I promise.
The next build is for my wife and a bit of a challenge which I’m looking forward to.
So the question is has any one tried this...
Q85 36V250W Roller Brake Front Driving Hub Motor

I've tried the normal Q85, but not the roller brake one. Why do you want a roller brake?

Ah d8veh, I guessed you would be first on this!!! It’s for a pashley poppy, she loves the bike but finds it v heavy. I was thinking of this motor or bbs01 as it’s drum brakes. What do you think?

Iinstalled my Q85 in a 16" wheel. It was the 328 rpm one, so spinning fast in a small wheel meant a lot of power and totque. The Q100s are a bit bigger. When in a 26" or 700c wheel, they're OK, but not the most powerful motors. I would say that the Q85 in a big wheel would be OK as long asthe rider isn't too heavy, say 75kg max. You need the 36v 201 rpm version.

Thanks d8veh, appreciate your advice on this again
