Shaft Drive Transmission System (SDTS)

The Sussex Shaft Drive Transmission System (SDTS) has been in production since 1991. Our latest generation of shaft drive uses bevel gears made of heat treated cromoly, paired with high quality sealed cartridge bearings coupled to a steel shaft rod – all sealed inside a lightweight, durable alloy housing. Our patended design delivers a smooth, consistent power transfer from the pedals the to rear wheel, while giving the bike a sleek, modern look. Click Here to View the Shaft Drive Animation.

To work with the SDTS, Sussex has developed a wide range of frames made specifically for the SDTS, including 700C city/hybrid frames, 26" Cruiser frames, 26" mountain bike frames, and 20" folding bike frames. See Example Bicycles Using the SDTS. 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.
