Owuru propulsive module

MORE THAN JUST A MOTOR

Taking inspiration from the automotive world, the OWURU power unit combines intelligent assistance and gear change functions into a single unit. But more than in a traditional motor and gearbox, the two functions form an inseparable whole to provide a new kind of riding experience. In perfect symbiosis with the effort of your legs, the system continuously adjusts the gear ratio, optimising the delivery of power to the wheel. The result? A fluid, jolt-free driving sensation and a response adapted to all types of terrain.

AN INFINITE RANGE OF GEARS

Unlike traditional gear changes, OWURU offers a continuously variable transmission (CVT): you never find yourself between two gears, as there are an infinite number within a certain range. This feature becomes all the more interesting because the system is capable of automatically shifting gears for you—transparently and naturally. Your effort, combined with that of the electric support, is transferred to the wheel as efficiently as can be.

BYE BYE DERAILLEUR

OWURU puts an end to derailleurs and the limitations they impose. With the gearshift function integrated into the central module, the derailleur is replaced by a simple, robust chain line with one fixed sprocket. OWURU shifts gears smoothly in any situation, whether you’re at standstill or under load. Thanks to the continuity of the gearshift and intelligent assistance, you can seamlessly accelerate with full power. What’s more, the internal gearshift system is protected from external impact.
That means both carefree and maintenance-free journeys.
CADENCE SETTING CONTROL

3, 2, 1… MOUNT, SET UP, DRIVE!

On a derailleur bike, you have to constantly manipulate your gear control to maintain the cadence that suits you—the number of crankset rotations per minute. With OWURU’s Cadence Setting Control, you choose your personal cadence once and the system takes over: it will smoothly adjust the gear ratio according to the speed of the bike and the pedalling torque.

A little extra: the level of assistance and cadence can be adjusted via the same interface on the handlebar. A simplified dashboard for a full-on comfortable riding experience.

technology:

mechanics
+ cutting-edge
electronics
Dual belt drive
Internal transmission between the various components goes via two synchronous belts, specifically designed for smooth, quiet operation.
Planetary gearset
This is the heart of OWURU technology: the planetary gearbox intelligently combines human power with that of the two electric motors to produce a continuously variable transmission.
Dual Motor
The propulsion module uses two brushless electric motors, each connected to a part of the planetary gearbox. One handles the speed ratio, while the other handles the level of assistance. Both motors supply power to the output.
SINGLE PCB
The two electric motors and eight sensors are connected to a single control board for clean, efficient integration. The board incorporates a powerful microcontroller that modifies motor commands 20,000 times per second.
