    Hello Everyone, Starting work on my 1989 Mini. Thinking of keeping the original gearbox and mounting a Hyper9 motor directly on top of it. Using SilentSync sprockets and belt as a drive system. Have something similar to bdrive.ch ´s conversion in mind. But interested in using the Hyper9 9 and...
  2. Converting 2002 VW Golf

    All EV Conversions and Builds
    Hello! I am considering converting my 2002 Golf to electric. For my daily commute, I need a range of at least 60 miles and a top speed of at least 75 mph, although I would prefer a range closer to 90-100 miles if I can make it work with my budget, which should probably max out around $13000...

  4. FS: Genuine GM EV1 / S-10E Drive Unit - AC Motor, Gearbox, Differential & Wiring

    Classifieds
    Yes you read that right and this drive unit didn't get crushed, in fact it is new and un-used as it was purchased many years ago from someone who knew a GM dealer that had one! I've been saving it for a special project of my own but decided that I have too many projects and too much stuff in the...

    These E560 Gearboxes were custom built for 3-phase Siemens Motors.

    Technical Discussion
    Hi Everyone, I am new to this forum and am yet to build my first EV. I have a general question about transmissions so please forgive me if it has been addressed before. Most builds I have seen on the Internet have connected the motor directly to the gearbox as a direct drive. The Flywheel...
  8. New Conversion-Ford Transit Van

    All EV Conversions and Builds
    Hi all, Im looking to convert a rear wheel drive transit van to battery power. My plan is to do this as simply and inexpensively as possible, I 'only' need a 14 mile range and 30 mph top speed, although I do have to negotiate the occasional hill. My theory (feel free to comment!) is that by...
  9. '78 Vespa Bravo conversion: Use old gear reduction unit?

    Electric Bikes
    Hi y'all. I'm considering an electric conversion for a engine-less Vespa Bravo I just acquired. I'm in the very initial brainstorming stage, so I haven't chosen a motor but this is just for fun and I want to go cheap. (So no hub motor--that way I can use the old brakes) Anyway, the original...
