I have been planning this build for quite a while. I statrted dreaming of a race bike when the first death race bike was announced. I have slowly been gathering the parts to do so. Some I have held off as I have been awaiting their arrival to the general public. Matt was going to make a 4" astro motor and I know how powerful a single 3220 is, so figured the 4" would be able to handle the riggors of racing. So far it's not available. Then the Colasus was announced, and still no real availability, plus no control that can realease the beast. I did buy a 24 FET from Steveo in anticipation, but so far it has only seen some use in testing. I bought some front forks, and a rear shock thinking I wanted a full suspension bike. My goal has been to build the bike from scratch, so I also bought a bottom bracket tube and cartridge, and head tube bearings.
So while awaiting the arrival of my dream brushless motor, an Etek brushed motor shows up on the forum for a really good price. I have one of these in my electrathon and at 1000 watt average draw and bursts up to 3000 watts on only 24 volts it reamains barely above ambient. Seems to me this could make a nice race motor at 72 volts, although a bit heavy. I have also been playing with the devolper kit Nuvinci and am really impressed with it, so I picked up another of these. I also have a crap load of the Sony 18650 v batteries coming (another great to hard to pass up deals here on the sphere), but would prefer to use the turnigy nanotechs.
While dayreaming of my bike one day I come to the conclusion that building a frame from the ground up may be more work than I want to do, not to mention the lack of a frame jig. I come up with the idea of buying a steel mountain bike that has a 1 1/8 headset and 3 piece crancks cut the rear end off and just make the extended rear end. This assures a straight frame, and removes a whole lot of work. I start searching Craig'slist and after just a few days come accross this for $75
It weighs 41 lbs as pictured. Steel is heavy!
