So what do 2 bored engineering students do to fill up their time on summer break?
They build 2 motorized bicycles.
In May MJ and Greg bought 2 Schwin bicycles and modified them to fit a 50cc 2-stroke engine onto the frame. I was thankful to see that they bought new bicycles for this little project and not modify their existing bikes.
They spent about 4 hours on each bike installing the engine, sprocket, gas tank and controls. The rear wheel sprocket and engine sprocket were a bit of a pain to line up. They also had to fiddle with the brake controls so the clutch control worked.
The engines need to be pop started by pedalling the bikes and slowly releasing the clutch. After assembling the bikes, it took another 2 hours to tune the carbs and get everything working smoothly.
The bikes will run at 25mph with a 75 mile range.
It’s pretty cool to watch the bikes go.
