This is the most dangerous crazy jet bicycle created by 35 years old British plumber Colin Furze. He decided to give a new-life on this old bicycle who can reach speed up to 50 mph by homemade jet engine. At speed up to 40 mph it seem okey but from 40 mph to 50 mph is so hard to control and start shaking. At speed more than 50 mph you are on high risk level and have been lucky to stay on two wheels for about 5 minutes. However if you need more adrenaline take a ride.
