I'm gathering the components for a build, just wanted to put my ideas out there to see if I'm on the right track. I'm starting out with a schwinn heavy duty http://www.americasbikecompany.com/2009_Schwinn_Heavy_Duty_Yellow_Black_Bike_p/209heavyduty.htm I bought used (planning on upgrading the brakes obviously). What's nice is the bike already has rear dual racks for mounting everything.
Only thing I have so far is the motor, did a little research on Heinzman motors and they seemed well made (the price was right too):
looking at controllers on ebay, would this work?
and of course, batteries. I'm probably going to go the SLA route (3x 12v 10AH) just because it's the cheapest at this point, hoping to upgrade as new stuff comes out. My daily commute is going to be 4 miles one way, max. I usually take my fixed gear road bike, but it sucks riding to work when it's hot out, and I can't carry much. I've been building bikes (mostly mountain) for a few years so I'm pretty handy on that end, just starting out with the electric stuff. Any input is appreciated!
