Dynamic Bicycles’ chainless bikes combine two innovative technologies to create a new generation of bikes that are smoother to ride, easier to operate, and simpler to maintain than traditional chain bikes. The first of these technologies is our patented shaft drive for smoothly transferring power from the pedals to the rear wheel; the second is Shimano’s advanced internal gear hubs, whereby all the gearing is neatly tucked away inside the rear wheel. By integrating our shaft drive with Shimano’s internal hubs, our bikes not only have a sleek, modern look, but they deliver an incredibly smooth ride, great performance and eliminate the number one complaint people have always had about their bikes – the chains and derailleurs. With our shaft drive bikes, there is no more grease; no more mess; no more cuts on fingers or tears in clothes; and no more chain and derailleur maintenance. Just pure, worry-free riding fun.

The shaft drive uses two sets of spiral bevel gears and a shaft rod to smoothly transfer power from the cranks to rear wheel. The bevel gears are made of heat treated cromoly and paired with high quality sealed cartridge bearings coupled to a steel shaft rod – all sealed inside lightweight, durable aluminum alloy. Our shaft drive, now in its third generation, has been in production since 1991, and is already on tens of thousands of bikes all over the world. To see the shaft drive in motion.
