No hub motor. No middle motor. 
Protanium makes a revolution for electric bicycles
with a completely new motor concept!
A shaft drive motor system. The Protanium shaft motor.
Protanium shaft motor is based on a shaft drive. Shaft drive propulsion has existed since 1890. Among the many benefits of a shaft drive bicycle is that it eliminates the chain, chain wheel and sprockets all of which require regular service and replacement. The shaft drive requires no maintenance and is much stronger than any chain. A shaft drive is in contrast to a chain: without any oil and dirt.
