Default 3 Speed Trek

I finally finished my 3 speed bike that hopefully will be my daily rider. I started with a mid 90's Chromoly Trek Mt. bike frame. Laced up my own double wall Rims since I wanted something very reliable for the 3 speed Sram I Motion hub and the pricey Michelin tires. Installed the RS Jett front fork I found on e-bay. Had to modify the head tube for the 1 1/8" threadless fork, since it was originally a 1' fork. Also has modified expansion chamber from pocket bike.* I built the entire jack shaft set up, since I wanted to try my own version. The bike is all wired for 12 volt SLA battery which will set on the small machined rack in back. It will have working 12 l.e.d. headlight, twin l.e.d. tail lights and 12 volt Motorcycle horn.* All brakes, cables and add on parts are new. The only thing I have left to do is install the Stewart Warner "old style" speedometer, and add another small tensioner for the pedal chain.** John

I like the jack shaft design, I have not seen it done that way yet.

I have to put in a Big thanks to Jeff (Toker ace) for prodding me to build this bike. He kept on me about building a shift kit, multi speed bike. He said if I ever ride one I will be hooked and won't care to ride another single speed.
I guess I will find out as soon as some of this Fricken snow melts and I can get it out in the street.
If thats the case I will have several single speed MB's to sell.

Thanks again Jeff

John
