Nitrous for under $30! (Motorized Bikes) 

In the video we used an Anbull 66/80cc 2 stroke engine and an older Huffy Cranbrook with mountain bike front forks and 24 inch wheels (The bike came with 26 inch wheels). With the 8 second shot of nitrous it has about a 50% hp increase. With the bike in the video the shot makes the bike push about 5 hp and has a top speed of 50 mph.
