From One Off Titanium
This all-terrain handcycle is the first to bridge the gap between today's road only hand cycles and the chair-lift dependent downhill racers. With bicycle cranks for propulsion and a steering similar to the downhill racers, this vehicle can climb Mt. Snow and descend at speed with safety.
With unbeatable maneuverability and a rider position designed for great climbing traction and power delivery, the One-Off Handcycle is an arm-powered vehicle that is analogous to the modern mountain bike. It has exceptional high-speed cornering capabilities, and a three-wheeled braking system, so that it meets the 'moose test' for safety with ease. A handcycle with serious attitude!
Frame Material: all tubes 4130 chrome moly steel.
Vehicle Weight: 50 lbs. This varies widely depending on tires, seating, and component choices
Wheelbase: 50 in.
Overall Length: 70 in.
Overall Width: 34 1/2 in.
Ground Clearance: 6 in. Knees, toes, and hands are all approximately this high
Overall Height: 28 in. to top of seat back
Brakes: all three wheels disk
Transmission: two Schlumpf Mountain Drives and an 8 speed derrailleur gives 24 widely spaced gears with no overlapping ratios ranging from 3.7 to 55 gear inches.
Turning Radius: 9 feet
Remember, it's not the number of gears that matters as much as the range of ratios. Our 24 speed transmission system offers a far wider spread than a regular mountain bike with 27 gears. The gearing can be easily changed up or down by changing sprocket sizes. The stock gearing gives a low of 3.7 gear inches (about 5 revolutions of the cranks for one revolution of the rear wheel) and a high of 55 inches, that's equivalent to the normal gear for a BMX bike.
Being experts at bicycle components, we can offer any conceivable gear ratios. We have gone as low as 3/4 gear inches (this is really only useful for climbing up the side of a building with one hand).
