New Chainless Bicycles Deliver on the Promise of Fun, Worry-Free Riding


Medway, MA, January 21, 2005 -- Dynamic Bicycles , Inc. this month unveiled its innovative line of chainless bicycles that promise to make riding more fun for more people.

Chainless bikes eliminate the biggest complaint riders have always had about bicycles – greasy, maintenance-prone chains and derailleurs. Instead, Dynamic Bicycles“ sleek mountain bikes and road bikes use a fully enclosed shaft drive and all-internal gearing so there are no exposed, moving parts – meaning no grease to get on hands or clothes and no more ”chain bite" More importantly, these chainless bikes deliver an incredibly smooth ride, exciting performance and are virtually maintenance-free.

The End of Bicycling As You Know It
Dynamic Bicycles“ chainless system replaces chains and derailleurs with a clean, maintenance-free shaft drive and Shimano ”s self-lubricating internal gearing technology. Instead of external, fully exposed chain and derailleur gear components, Shimano “s advanced internal gearing compresses all of these components into a compact, highly efficient rear axle (hub) that looks as great as it performs. Controlled by Shimano”s smooth and responsive twist grip shift, Dynamic Bicycles chainless bikes deliver a full range of gearing with a few simple twists of the wrist. In addition, unlike traditional bikes , chainless bikes do not require movement to shift gears, so the rider can change gears at a stand still or while on the go, ensuring that the rider is in the correct gear for any situation. The rugged, aluminum shaft drive and Shimano"s internal gear hubs are each designed to require very little maintenance and are sealed to safely protect them from dirt, debris and damage.

“ Shaft drive bicycle technology has been around for a while and is recognized as a rugged and reliable system,” said Patrick Perugini, founder of Dynamic Bicycles. “However, only now – by combining our proven shaft drive with Shimano”s newly advanced internal gearing technology – can Dynamic Bicycles chainless bikes offer levels of performance, reliability and versatility that surpass those of chain bikes"
