The Internet Collaboration Electric Bike
I was riding my Project #001 bike this morning and on the way home I spotted a nice 24" wheel bike that was out on the curb ready to be picked up by the garbage men. I quickly grabbed it and saved it from the sad fate that would have befallen it 15 minutes later.
So here's what I'm going to do. Since I have a welder and can make design changes to the frame I'm going to modify this frame and I'll be taking input from people online. This might be the first collaboratively developed electric bike (at least to my knowledge) ever done online.
First let me set some ground rules:
1. The bike was free, so don't suggest expensive solutions... this will be an inexpensive bike.
2. As a design goal I'd like to keep this closer to a normal bike than my other complete "from scratch" projects. Ideally the frame alone will be changed and everything else from the old bike is used. (brakes, derailler, etc)
3. I'd like to keep this one within the "pedals/750 watt/20 mph" rule or at least close enough that it could be crippled so as to obey that format.
I could make more rules, but people will start breaking them from the beginning. Maybe "suggestions" are a better way to put it. :wink:
So here's the frame and it's dimensions: (roughly from left to right)
17.5", 16.5", 13.5", 20", 22", 4.25", 14", 1.5", 39.5"
You can assume that the fairings that I make for the Project #002 bike will be also used on this one. (I'll be making a mold that can produce multiple final copies) It's going to be a "Road Racer" style... that has to be more a less a given for anything I build.
