Pictured is a BionX e-conversion on a Norco Indie 4 professionally tuned up today with new derailleur, controller, and brakes installed. The controller has a throttle to operate the motor in addition to moderate pedal assist. The frame is 55 cm, the ebike motor is 350 watts, the battery is 48V (6.6 Ah). (I am willing to sell this older battery for $100 on its own). I also have a second identical battery I bought last year from bx-legacy for future use (pictured on the bike). I am willing to sell this batter for $150. Conversion, maintenance, and cost of electric bike and parts to date is well over $2000. Selling the ebike and both batteries for $500. Price is firm.
