    Electric GSXR 750 Project

    C Savaria and me are starting a electric motorcycle project. We already have are motorcycle, a 1992 gsxr 750 in working condition. We are entering the second third week of the project, and we need some information about the electrical standards we need to respect. Also, we are both students in mechanical engineering, and we are trying to find information that could help us with the engineering of the electrical system (formulas) .

    We are running on a very limited budget, so a 48 volt, deep cycle lead batteries would be are choice. We know that the motor we are probably going to buy need 150 amps.

    If you have any suggestions for us, don't hesitate to contact us.

    do more than 48V if you want the thing to go a decent speed, and with 150A that motor might be a little small.

    What motor is it?

    It's a 48v EMC-R. it comes as a kit with a Alltrax 4834 controller.

    A bit small IMHO.

    Maybe something larger like this:

    It'l be a bit slow otherwise, but if you just wanna get it running, get a large gear reduction, like 6 or 7:1 ratio.

    the plan is at least 70 km/h (40-45 mph). we were planing for a big gear ratio.

    For just a bit more money, the ME0709 with Alltrax 7234 is a much better package. It will handle 72V, but you can run it at 48V until you can afford more batteries (actually, only two more 12V lead acid).

    See kit #4C

    The bike only has kmh on the speedo. My guess is somewhere outside of the states or the UK.

    I guessed wrong Welcome to elmoto. I agree with the others, you will probably be disappointed with 48 volts. Upgrading is not as simple as buying more batteries. I would suggest looking at more of the conversions on here and doing more research before spending any money.
