How the Vivax Motor Works
A very light cylindrical-shaped motor, gearbox and free wheel unit slides down and is fixed inside the seat tube.
The bevel gear on the end of the motor protrudes inside the bottom bracket.
This bevel gear drives a gear fixed to the axle of a Shimano Hollow Tech II crank axle.
When the button is pressed on the handlebars it powers the motor, helping the rider to turn the cranks, making pedalling easier or faster.
There are 3 ways to turn off the motor when cycling –
1. Pressing the button a second time will switch off the motor.
2. Applying the brakes and stopping. Once the motor is displaced (stopped) it will automatically switch the power off to it. just press the button again to re-introduce the power.
3. The rider can create resistance against the motor by physically stopping the cranks from turning with their legs, this will also displace the motor.
