|completed motorized bicycle|
Every year my car club The Road Lords, puts on Scarlett Fever. Scarlett Fever is a benefit car show/concert/art auction for our girl Scarlett who is battling Rett Syndrome. During the show we raffle off items to help raise funds for Scarlett's medical expenses. This year, I offered to build a motorized bicycle for the raffle. I have always wanted to build a motorized bicycle but it wasn't until I saw an article in Make magazine that I realized there were relatively inexpensive kits available that should make it a pretty easy process. I really couldn't justify building one for myself, but the raffle gave me the perfect excuse. Now I could satisfy my urge to build and ride one without incurring the expense or worrying about storing it in my overcrowded garage afterwards.
|1903 by Felt|
I could have used any bike but I have been enamored by the Felt cruisers ever since I first saw them. They aren't cheap, but they are built with quality parts and the styling can't be beat. Their 1903 was just begging for a motor! With the springer front fork, large leather seat, huge top tube, pinstriping, and fat white tires, it looked like one of the early Harley's. I was fortunate to find one locally at Cags Cycles.
|Grubee Skyhawk motor kit|
Just a word or warning. IF you have a bicycle with standard geometry the motor kit could install in a few hours by anyone with moderate mechanical skills. But because of the unique styling of the Felt 1903, nothing fit out of the box. There was a significant amount of machining involved to get the motor to work with bike. This motor, with this bike, is not a project for a beginner. There is a lot to this build, so I have broken it up into parts. Click on the links below to view the build.
