Re: Bike Pusher

My experience you need traction but get a lot of bounce, you need to spring load it down, or add some weight, like batteries, but then add a suspension frame (to hold batteries), a tire with a lot of rubber/air is a bouncing ball, on a rough road it will spend a lot of time in the air, not road.

The only way that I have been able to cool motors is with air flowing through the internal guts was to use a pressure type blower, what I found works well is a brush less motor fan (if you can't find one, a air bed inflate type will do but with brushes will have a short running life) that will push ...

On a trike using 16 inch front wheels, there is not much rubber, and at air pressure almost no shock absorption with that size tire. My thought is to take a 20 inch wheel rim, remove the spokes, lower air pressure in 16" tire, insert into 20" rim with contact cement, or epoxy, inflate 16"tire only e...

Re: how do i fit this sprocket in this shaft of the magnet?

That motor shaft was meant to slip fit into a planetary gear box, if there is enough shaft left after the sprocket is on the shaft (with motor running) you could use a mototool type grinder with a cutoff wheel to grind a retaining ring groove into the "d" shaft
