Gravity biking is one the most adventurous sports that increases the adrenaline rush of not only the participant but also the spectators indulged in the event. There is no scope for error, as it may cost you the title or sometimes life. Making gravity biking a bit safer and superior for the rider, Mexican designer Andrés Alvarez has come up with an improved version of a gravity bike named the “Mamba” that helps the rider keep his/her body closer to the ground and experience the sensation of flying over the pavement. Made using lightweight materials, possibly carbon fiber, the velocycle is easy to control and carry on a car truck. Designed to be extreme, the Mamba simply enhances the biking experience of the rider.
