Hey. I just converted my Schwinn S-30 full suspension mountain bike to an ebike. I took the cheap route at the time cause i didnt know any better but i bought a brushed WE 600w motor. I ran it fine at 36V. Ran it fine at 48v. Ive been running it at 60V for about two months. Has a pretty good assisted range of 15 miles. It has an unloaded free wheel speed of 67mph. Not sure what the loaded speed is havent paid attention... just added a cheap schwinn speedo today. Im currently running (5) 12v 12ah SLA in a MTX trunk bag. Im running the stock 36v controller @60v unmodified. Im thinking its a 20A controller. I havent had any trouble whats so ever. The motor does get a tad bit warm. Im wanting to use this as a daily commuter. My current batteries wont take me the full lenght of my trip and back to to work. Im willing to spend some money prob in the battery department. I wanted to get two ping ping Lithium packs off ebay a 36v and a 24v 20ah pack and wire them in series to get the 60v. Or possible get 5 (18ah) SLA. Im satisfied with the controller performance. Im a robust fellow i dont need the super torque i can pedal. Most of the hills where i live... speed and momentum is all i need to get through them. Im thinking i need some battery monitoring device. Im asking for any suggestions at all on what i should do. A new hub motor is out of the question for the most part. I want to go up to 72v possibly higher but i dont want to modify a controller and clueless on where to find one in the US.
