Sussex Enterprises Co., Ltd. is the world's most experienced manufacturer of shaft drives for bicycles, recognized around the world for it's premium quality product. Sussex has been manufacturing the shaft-drive transmission system for Chainless Bicycles since 1991. We have developed and patented this system to add unique functionality to bicycles. The shaft drive transmission system uses specially-made spiral bevel gears and sealed bearings to rotate a carbon-steel shaft rod inside the precision machined aluminum housing. This shaft drive system replaces traditional chain/derailleur systems with a super smooth, clean, efficient, durable way to transfer power from the pedals to the rear wheel without the grease, mess and maintenance of chains and derailleurs. Our shaft drive transmission system is protected by patents in many countries and our chainless bicycle has achieved a worldwide recognition as safe, smooth, and high quality bicycles.

In addition to manufacturing the shaft drive transmission system, Sussex is also a full-service bicycle company. We are experienced in specifying, sourcing, purchasing, and assembling complete bicycles using our shaft drive system and a broad variety of components and accessories.  

Sussex is currently looking for distributors in select regions. Please contact us regarding distribution availability in your area.
