Re: 1980 Pedal Power front friction drive 1HP 12v
I have still have one in a box which came on a three wheeler I once had (and wish now I had kept for a gas project bike). It ran off of a garden tracker battery which of course was quite heavy. It would have been adequate for running a three wheeler to the store for groceries and that sort of thing. Not very fast, in other words. It is a Bosch starter motor and I don't know what would happen if you tried to give it more juice, say like 24 volts. The newer batteries would certainly weight a lot less than a garden tractor battery. Considering what is available today in electrics, this is a pretty primitive rig, but it worked. I think this would be 1960s or 1970s. I can dig mine out to see how it mounted if you want. I don't remember now.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
