    Talking Building a electric bike!

    Hi everyone,

    I've been working on a design in Design Workshop Lite (A Macintosh CAD application) for a custom built electric bike.

    The entire bike will be custom made, custom fabricated and built.

    The hardware store will be where I will get the tubing for the frame. I haven't decided on a specific electric motor yet. I will be using a standard sized bike tires for the tires. (27 inch or a little smaller)

    Other than that and the motor everything will be custom made.

    Cool, I have a hand drawn design I should snac. It has an "A" type frame. Think of the letter "A" and tilt it about 60 degrees to the right. The batteries, 30 X 1.2V Nimh = 36V are mounted inside the frame. They can be easily removed and since they're regular "D" cells (Matched BTW) they're easily replaceable.

    The motor is a crank motor. Think of the Bionx hub motor but instead you're pedaling the the shaft and the motor casing has a gear cog on the outside which goes to the rear derailleur.

    The only downside is the lack of regen braking. But that's what happens when you have a freewheeling rear hub and a freewheeling crank.

    FS... what kind of specs and technical details does your design have?

    Reply to Zeuser - Technical Specs and drawing

    Zeuser -

    The attached image is drawing 1.0 design of the motor bike.

    It's pretty simple at the moment, but im still working on it.

    Currently it is powered by a 12-Volt battery and a 12-volt electric motor, Belt-driven to the rear tire.

    Currently the design is 4 lets say "w" shaped copper or other metal tubing makes the frame. (top and bottom). The design is made specifically for me, since I am VERY lightweight person (122lbs) Im using the less-expensive copper tubing which dosen't hold as much weight. The drawing will improve with time, still working on it. The battery and the motor sit in the mid-center of the frame, your legs sit on a top of the frame where (not added yet) there is a seat and foot rests. Adding more as I go, like blinkers, lights etc.
