Goal was to create a (somewhat) stealthy commuter bike that could break 30mph when i felt the urge to. The "before" is my commuter bike from college...i used to be cool and could ride fixed gear on the flat roads of Ft. Collins, but have afterward changed over to the freewheel. (30MPH in fixed gear makes for a steep gear ratio or very fast feet
). Nice 4130 frame with solid front fork dropouts. https://www.statebicycle.com/collection ... te-black-6
The components came from http://www.ebikes.ca/shop/electric-bicy ... basic.html
-9C 2706 hub motor on a 700C Alex rim
-35amp sinewave controller
-"T" thumb throttle
The battery is a beast of my own creation. Essentially dismantles qty 6 "20v" 4ah Dewalt Chinese knockoffs assembled into a 18560 15S 4P configuration arranged to accept fully balanced charging from the 8amp 4.1V dewalt charger (approx 4 hr total charge time).
The advantages of this are fairly obvious (cost effective ($200 for 56V 8ah) and supposedly long lasting)...the one disadvantage is that you have to change the charging plug 3 times to achieve a full charge (1 charge cycle per 5s stack). https://www.amazon.com/FirstPower-Repla ... FIRSTPOWER
The other nice feature is that the batteries come pre-spotwelded with nice solder tabs on them.
Nice and simple cockpit
