| May 9th 2009 Breaking News! | I am starting a new motored bike project using a kit from this company. http://www.ezmotorbike.com/ other than the small 4 stroke motor, I like the way the drive and clutch is constructed, it is very simple and efficient. Go to this website for photos. | |
| http://motorbicycling.com/ | These forums are a great place to learn about what it takes to start, and successfully complete a motorbike project. Lots of helpful people and information here. | |
 |
The inspiration for this project comes from a couple of directions. Shown on the left is a 1903 Harley Davidson, the first model produced. Notice that it is a moped so, this project goes back to he simplicity of this first Harley so that it, the historical look and the simplicity. | |
|
This is the Felt 1903 Model bike. It is
no doubt a take-off of the 1903 HD. When I saw a Felt
frame like this on another bike model, I thought the top
frame looked like a natural to convert into a fuel tank.
|
Someone did a real nice conversion on the Felt 1903.

|
This is the model of Felt bike I thought would be cool to convert to
a motored bike. It's the MP bike.
|
After I tested for leaks with air and found that it leaked like a
sieve, I decided to open the top frame and here is what I found, large
holes on both the front steering tube and also the seat tube.

This is what the frame/tank looked like after the
bungs for the filler and the fuel petcock were
installed, and the section was re-welded.

Probably the most innovative thing I have done on this project so
far, was to use a stainless steel clamp for the front motor mount. This
clamp is rubber coated on the inside and is used to stop leaks in pipes.
I could not use the spacer and clamp that came with the motor, because
of the larger than standard diameter of the tube. I merely made a simple
"T" shaped bracket which bolted to the motor. So far, it seems to be
working.
