The all new twohubs TUmotor eGravel is our revolutionary build of all the latest greatest components currently in the cycling market. We partner up with RockManDo, a 30 year old company based in Essen, Germany. They're an industrial generator power supply company, but the rise of the cycling division started in 2008. The owner is a true bike enthusiast, who designed the TUmotor over 2 decades ago. Many generations later, this is one of the most simplest, cleanest looking and reliable eBike motor system.
The global patten TUmotor uses a 6,000 RPM brushless motor and combined with a turn-in geared transmission that spins down to 100 RPM to the cranks. The 90 degree turn-in gears feature in the transmission allows you to pedal the crankset like a regular bicycle bottom bracket with no motor drag, but allows the motor to assist your pedaling with smoothness and ease. The transmission is made in the same factory as certain popular US electric car company transmission, to ensure the highest quality and reliability. The transmission also has multiple torque and cadence sensors which the motor to be able to become torque base at low cadence and allow cadence base pedaling with higher cadence.
