Chain Innovations

Dynamic's chain bikes are the first internally geared bikes built specifically for performance, including the world's first internally geared drop bar road and commuter bikes. These bicycles offer a unique blend of performance, verstility and low-maintenance not available on any other chain-driven bikes. They are the perfect complement to our chainless bikes, delivering a new level of performance, yet still retaining the inherent simplicity and ease of maintenance that you've come to expect from Dynamic.

At the heart of all of Dynamic's bicycles are the Shimano family of advanced Internally Geared Hubs. These are the world’s best performing and most reliable family of internal gear hubs. We combined these hubs with innovative shifting and frame components and fresh ideas to create bikes that will keep pace with your riding ambitions.

Road Riding

Dynamic's internally geared road bicycles combine the Shimano Alfine hubs with the Versa road shifter and crankset components and a purpose-built aluminum/carbon frame into a highly efficient, versatile and speedy road bike. Our Synergy Road Bike offers 95% of the gear range of a compact double crankset, and 92% of the range of a full triple crankset, without all the overlapping and redundant gears needed on a externally geared bike. Dynamic's road bikes offer fast, smooth, precise shifting as well as responsive handling and crisp braking to make distance riding, fitness riding or commuting a pleasure.

Commuting

Dynamic's internally geared commuter bicycle, called the Beantown, combines the Shimano Alfine hubs with the Versa road shifter and crankset components, dual disc brakes, puncture-resistant tires and a custom-designed steel frame into a highly efficient, versatile and weather-resistant commuter bike. Our Beantown model offers 95% of the gear range of a compact double crankset, and 92% of the range of a full triple crankset, without all the overlapping and redundant gears needed on a externally geared bike. The Beantown also offer fast, smooth, precise shifting to match its confidence inspiring dual disc braking in all weather conditions. For all-season, any weather commuting or touring, the Beantown will never let you down.
