And curiously, the Easy Rider bikes were never associated with any particular builder." Whose hands turned the wrenches? Who welded the steel? Most of the time, d'Orleans says, choppers are associated with their builders, "because they are an artistic creation. I mean, suddenly people were building choppers in Czechoslovakia, or Russia, or China, or Japan." The bikes in Easy Rider, d'Orleans says, "did more to popularize choppers around the world than any other film or any other motorcycle. The "Captain America" bike is an unmistakable and legendary chopper, and has made an enormous impact on the world of motorcycling. I mean, suddenly people were building choppers in Czechoslovakia, or Russia, or China, or Japan. They did more to popularize choppers around the world than any other film or any other motorcycle. And the man who designed and coordinated the building of the motorcycles, Clifford Vaughs, says he and the other bike builders have not received proper credit for their work. (The three other bikes used in the production were stolen prior to the film's release.)Īccording to Brian Chanes, acquisitions manager for the auction house, the bike's estimated value is between $1 million and $1.2 million.īut despite the bike's fame, the history of the creation of the bikes used in Easy Rider has for many years been largely unknown. The bike currently for sale was partially destroyed in the film's finale, the auction house says, and then rebuilt by actor Dan Haggerty. Peter Fonda, who played Wyatt in the Dennis Hopper-directed film, rode the so-called "Captain America" bike, named for its distinctive American flag color scheme and known for its sharply-angled long front end. 18, the Calabasas, Calif.-based auction house Profiles In History will auction off what it says is the last authentic motorcycle used in the filming of 1969's Easy Rider, and what some consider the most famous motorcycle in the world. He is obsessed with keeping up to date with all the latest tech, is fixated with the smallest details and is known for his unique opinions.Peter Fonda rides the "Captain America" chopper in Easy Rider. Oscar prefers lightweight road and gravel frames with simple tube shapes, rather than the latest trend for aerodynamics and full integration. He is particularly fond of workshop tool exotica and is a proponent of Campagnolo groupsets. Oscar has a BA degree in English Literature and Film Studies and has close to a decade of cycling industry experience, initially working in a variety of roles at Evans Cycles before joining Carbon Bike Repair. His favourite rides are epic road or gravel routes, and he has also caught the bikepacking bug hard after completing the King Alfred’s Way and West Kernow Way. He’s since been indoctrinated into gravel riding and more recently has taken to the dark art of mountain biking. He has been an avid cyclist since his teenage years, initially catching the road cycling bug and riding for a local club. Oscar Huckle is a technical writer at BikeRadar. Presta valves will close automatically, but the sprung Schrader valves are usually held open by a pin in the pump valve attachment (this means you don’t need any extra effort when pumping to overcome the pressure exerted by the spring). If it wasn’t there, the pump would just shoot open again. To prevent the pressure in the tyre leaking back out, the second check valve at the base of the pump closes. You extend the pump again, the check valve opens to refill the chamber with air and you repeat the process. That pressure increases until it exceeds that inside the tyre.Īt this point, a second one-way valve will allow air to flow from the pressurised pump chamber into the tyre. On a pump’s downstroke, a check valve (that allows air flow in one direction) seals the piston chamber, resulting in air being pressurised as the pump is compressed. This ‘overpressure’ forces air into the tyre, increasing its pressure too.Ī pump is just a manually actuated piston. The operating principle is simple you increase the pressure inside the pump until it exceeds that inside the tyre. Nick Clark / Our MediaĪ pump gets the air into your tyre. Some pumps feature rubberised handles for improved grip.
