Home Made Electric Bicycle

Here’s a short video of someone who modified his bicycle to go electric. He used a brushless motor and a pack of several Li-Ion batteries of 36V capable of 30A (about 1kW). You’ll, see, he uses two, four, six, or eight of these batteries. That’s 8kW = about 5hp. That’s more than a regular motoscooter can do! I don’t know if I haven’t done any miscalculations, but this thing could get you to 100km/h easily! The batteries can be recharged in about 30 minutes. Watch the video and pull your own conclusions. After you did that, leave me a reply using the form below!

    I think you may want to re-evaluate your conclusions. Batteries are the potential power available. The motor is only a 300W Brush less DC motor. Thats about 0.4 Hp. Which would work out to maybe 35 – 40 Km/h depending on driver weight. You could put 100 Kw worth of batteries on there and it wont make it go any faster.

    wrong
    motor is limited to 400 w input
    about 300 w output if you are lucky, to the wheel
    = about 19 mph on flat ground
