Hi All,
I have for a while been thinking of building myself another ebike. I want to try to get both better hill climbing ability and better top speed than the Torq, and building rather than buying seems the obvious way to do it. And of course it would need a on-road/off-road switch.
I was trying to work out what bike to start with - debating between a fast road racer type and a MTB - but in the end I decided to get what was most different from what I've already got. So I've just got this..
Its a 26" wheel and I want a rear hub motor system. Its as much an experiment as anything, and by choosing 26" I get something that could be transferred to another bike later.
Now the technical bit. I was planning on a Crystalyte motor, and that would certainly do the job. But if I work out what I need in the way of controller, battery voltage and current to make a Crystalyte in a 26" wheel climb hills, then its so much that it would do over 40 mph on the flat.
The Crystalyte is a direct drive motor, so maybe a geared one is needed instead. Maybe even an eZee hub motor. They don't come with fittings for rear wheel use, but flecc has done it, and I've got a lathe too..... So that's one option.
flecc, what's the overall width of your eZee hub with freewheel?
What other geared hub motors are available? Any ideas?
