Full suspended 40cc chainsaw mountain bike

Hey guys, here is my first motorised bike build, made from plywood, threaded rod, nuts and washers, and a 40cc chainsaw engine. Pretty good, had 60kmh/37mph top speed with it. The whole part on which the chainsaw is mounted is able to move up and down, there is a pedal that pushes it up (like a clutch) and large rubber bands pulling down. The engine shaft has a 30mm diameter friction drive. Kinda loud, good gas mileage, around 2L/100km (#metric #France #Europe)

After I made this bike I purchased a China crap kit s**t. Less power than a 40cc chainsaw! Slower! And the tank studs broke off when riding! Chain too broke when riding!

The Chinese engines are garbage, they need lots of help.
Nice work on the saw-bike. I love it!
