"Hank : Hand Bike"
High-performance “Direct –Joint Crank - Bike”
Another project of ours was to develop a cycle “Direct-Joint Crank- Bike” that uses the lever effect to enable riding using less power than existing cycles. While some riders enjoy extreme uphill riding that leaves them short of breath, for the casual rider, uphill climbs are a formidable foe that discourages them from long-distance tours and the daily commute on their bikes. To save the energy when riding, riders want to use the longest crank possible. To equip our cycles with cranks much longer than in any existing products, we devised a joint crank device where the crank is connected directly to the rear hub. Through endless hours of design, production and testing, with countless trials and errors, we developed the “Direct -joint crank- Bike.” The device embodies the best in 'internal hub gear' expertise, and does away with the chain, as well as the chain ring, sprockets, and derailleur associated with the chain. We continue to upgrade the product in preparation for its scheduled launch in the first half of 2014.
