Benchmark Drives, a developer of high-end drive systems, has added the 'Protanium Shaft Drive' to its portfolio just in time to debut at Eurobike.
At present, Benchmark Drives has secured exclusive sales rights to the shaft drive system for Germany, Austria and Switzerland from Protanium.
Offering various technical advantages, the completely sealed system offers the benefits of a motor and shaft drive, combined with a double planet gear capable of torque of up to 63Nm. An optical speed and tortque sensor manages the output and gives the rider nine 'support modes'. The rider does not feel anuy resistance when the motor is shut off.
An additional highlight is a removable display, allowing the rider to see their progress and level of assistance.
The first e-bikes with the shaft drive will be available in stores in 2013.
For additional information visit our fair booth at the Eurobike in Hall A2-209 or test the e-bike in the open exhibition grounds east – Booth 500.
