A Gravity Bike is a specialised two wheeled bicycle propelled by nothing other than gravity. Without pedals or a chain, Gravity Bike riders rely on steep gradients and gravity to reach incredibly fast speeds.

Historically, Gravity Bikes evolved from modifying a traditional BMX where a rider would add weight, alter seating and handlebar positions and change a bikes aerodynamic characteristics in the pursuit of greater speeds. More recently, Gravity Bikes have evolved to become highly specialised and purpose built machines capable of reaching speeds over 130kph from a standing push start.

Gravitybike HQ should extend your ability to share information, exchange ideas and make the Gravity Bike community more open, connected and professional.
