Hey guys, I'm very new to the world of e-bikes. I built a gas powered bike last year with my roommate (Which was a PITA) and now I want my own powered bike but without the mess of a gas motor. I am looking to spend less than $400 for a kit because I can't afford much on a college student budget. I have a very nice bike already and I think I want an electric front wheel to power it. From what I understand, a rear wheel would be better for traction and whatnot, but my bike goes through quite a bit, and I've bent my share of rear rims. The front wheel just seems to take less impact and therefore less of a chance to bend/break. Anyway, I could use some information. For example, Is there a difference in the motor of the 24v, 36v, and 48v hubs? They all look identical. Obviously there would be speed differences between the different voltages, but are they substantial? I only need the bike to get me around a university campus so I don't need to fly, but I still enjoy a bit of speed. Last question, what is the difference between the wattage of the hub motors? (i.e. 36v 250w vs 36v 500w) Does more watts = more electricity used = faster/more torque?
Thanks in advance, guys and girls!
