The Green Speed concept is an air-fueled concept bike that features a zero pollution effect on the environment through greenhouse gas emissions and especially being cheap and willingly available. The rotary air engine is lightweight, compact and powerful and is powered by compressed air from the two compressed air tanks. Because of its 3000 RPM of the engine, this bike can run only on one gear which is actually a sprocket bolted to the engine axis and chained with the rear wheel. The carbon fiber tanks of the bike stores the compressed air, when mass is produced, the solar panel generated energy will compress air and amass them in the tanks. The bike doesn’t contain any kind of lightening like headlight, indicator light or brake lights; instead, it contains three tiny cameras.
The engine that used is a rotary air engine. It is the invention of the Melbourne engineer Angelo Di Pietro. The engine is compact, lightweight and powerful and runs on compressed air from two compressed air tanks on the bike. It revs up to 3,000 RPM, and because of this, the inventors didn’t need any gear box on the bike. There is only one gear, which is just a sprocket bolted directly to the axis of the engine and chained to the rear wheel.
