There are just somethings you don’t see often when it comes to motorcycles, 2 wheel drive and tank tracks. Well, [jeep2003] has combined both those oddities into one project he calls the Track-Powered 2×2 MiniBike.
As his descriptive project name suggests, this minibike has tracks instead of wheels. The track assemblies originally came off a snow blower. As if just having tracks wasn’t difficult enough, both sets are powered. The back has a straight forward chain and sprocket setup while the front ads in a clever jack-shaft and universal joint contraption which is shown in the video after the break around the 3:08 mark.
[jeep2003] doesn’t say where the tubing for his custom made frame came from, but from the photos available it appears they were once old bicycle frames. The powerplant is a 6.75hp vertical shaft Briggs & Stratton engine. The output shaft connects to a Peerless 5 speed transmission that also has reverse. This transmission usually outputs to two rear drive wheels of a riding lawnmower. [jeep2003] dedicates each axle output from the transmission to power one of the two track systems.
Although this minibike won’t be breaking any land speed records anytime soon, we here at HaD still think it’s a pretty rad build.
