Was thinking of doing some barebones ebike builds to sell on craigslist that would reduce my install/setup time and the cost/maintenance to buyers...
My idea is a rear 900w MAC 8T freewheel motor kit with a single speed cog and one of these or something similar: https://paulcomp.com/shop/components/melvin-chain-tensioner/
This way, I don't have to worry about the customer's drivetrain, just dump the rear cassette and keep the two or three chainrings up front for flats/hills/self-power. This also frees up the right side of the handlebars for controls and existing finger-pull brake handles since no shifter levers will interfere with spacing.
From my testing the clutch will be just fine with dead starts at 48V/25A with a milder initial torque bump in software. I think if I did a bulk kit purchase from MAC and use a battery connection I have I could get this down to about $800 per conversion for the customer, and have the install done in less than an hour.
So what do you folks think? Has anyone done it? Pros/Cons?
