Details
 

The light, warp resistant hand-bike, with a deep twisting aluminium frame offers a multitude of various sitting positions which are possible through three various fork and crankshaft positions:
Position 1 Position 2 Position 3 kniend Position 3
Through accessories selected by yourself, the bike can be used according to your needs. All is possible starting from the pure, first-class performance racing-bike, the everyday-bike, up to the tracking-bike with mountain-bike profile wheels. You decide about the limit. The weight, beginning with 10 kg, is dependent on individual wishes (it is dependent on the size, the use of the bike and the amount of equipment). Different derailleur gears, `Rohloff Speedhub´, and several brake systems (mechanical and hydraulic, on the wheel-rim or using brake discs) are all available.

The use of an extreme warp resistant aluminium construction using the substance - 7020 T6 makes our hand bike extremely light. This substance is also used in the bike industry for production of special high quality frame constructions. All 3-layered heat priming that is put on after all welding has been completed leads to a tremendous improvement in quality and protects the frames from breaking.

Every hand-bike is equipped with special light manufactured crank-arms; these are extremely light and stable and are available in Individual lengths (150-200mm) and widths (150-500). These cranks are also individually available for all possible crankshafts systems (square, octagon and ISIS). Through a high precise ball-bearing system, power loss is reduced to a minimum. Precision ball-bearings guarantee an accurate and play-free function.

The discs have the rim size of 571 (from Triathlon); a high number of high-quality tires with low resistance to rolling can be used. Mountain bike rims (559) are also possible; thus, a high number of tire treads (from City-Slicker to coarse-tread), for the ordinary forest path can be used.

Our new absolute play-free and warp resistant systems with quick-locking mechanisms and 25mm diameter hollow axels from high strength 7075 T6 are available at an extra charge. If you wish, you can also receive ½" shafts and 'grab tire' as well as a mounting system for your wheelchair.
