It seems to me that a rear direct drive hub motor would give you everything you want, and weigh less too.
Direct-drive motors and less weight! Maybe a first.
So is your argument that because you are disabled you should be allowed to operate an ebike above the mandated maximum speed of an ebike?
That was not what the OP was advocating.
At the end of the day, an ebike traveling over 28mph utilizing motor power is not a legal ebike.
As far as the over 60 thing: you're doing long posts mid-week. Fits the profile of someone who's not pulling the plow. But the actual reason for my throwing that into the post was that a high speed...
For the riding that you do you make a great argument for an electric motorcycle. And over sixty was in reference to age.
Motorcycles with pedals are stupid.
People do get balance problems and can't ride two-wheelers. Many kinds of disabilities.
As far as going 35mph on an ebike when you're over sixty: vaya con dios.
If you're not doing the hard stuff, any bike will do. We were trail ridding our ten speeds before the invention of the mountain bike, so I'm rather casual in that regard.
