Shaft Drive Transmission System

The Sussex Shaft Drive Transmission System (SDTS) has been in production since 1991. Our latest generation of shaft drive uses an innovative combination of precision machined spiral bevel gears, shaft rod, sealed bearings and a patented bottom bracket design to deliver a smooth, consistent power transfer from the pedals the to rear wheel, while giving the bike a sleek, modern look. This results in many advantages versus traditional chain-driven bikes.

To work with the SDTS, Sussex has developed a wide range of frames made specifically for the SDTS, including 700C city/hybrid frames, 700C road bike frames, 26" mountain and comfort frames, 20" folding bike frames, and 20" BMX-style kids frames. Sussex has also developed specialized components to integrate the shaft drive with Shimano's advanced 7-speed and 8-speed internally geared hubs. Our unique design minimizes weight and increases efficiency and performance far beyond any other shaft drive on the market. By combining our SDTS with the Shimano hubs, our bikes deliver a uniquely smooth ride, high performance and low maintenance. We have also developed high quality crank arms made specifically for our shaft drive in multiple lengths and color finishes.
