Product overview
The 48V 500W 6.5/B50 rear motor is a spare part designed to restore driveability to your Smartgyro electric mobility machine. Ideal for replacing a worn or damaged motor, or one with a loss of power, it restores operation consistent with the original 48V configuration, while providing traction on the rear wheel.
Concrete benefits for the user
By replacing the rear motor, you restore the propulsion capacity of your machine, with a rated power of 500W suitable for everyday use. This type of rear motor improves the feeling of thrust on acceleration, and enables you to drive more smoothly when the original motor shows signs of fatigue (noise, loss of torque, intermittent operation), without modifying the vehicle's 48V architecture.
Technical specifications
- Type: rear motor (mounted on rear wheel)

Recommended applications
This 48V 500W motor is recommended for maintenance or repair work to replace a defective rear motor on a compatible electric scooter. It is suitable for users wishing to refurbish their vehicle for urban use, commuting or regular travel, as long as the original configuration is 48V.
Known compatibilities
Compatibility indicated: Smartgyro Speedway and Smartgyro Rockway (rear engine).
Installation and points to watch out for
Replacing a rear motor generally involves dismantling the rear wheel and checking the mechanical and electrical integration (cable routing, state of connectors, alignment). To avoid any errors, we recommend checking that the 48V and 6.5/B50 designation correspond to your exact model before fitting. In case of doubt, a diagnosis by a specialist soft mobility workshop is recommended.
Expert advice
Switch off the power supply and disconnect the battery before carrying out any work. Take advantage of the replacement to check the condition of the motor cable, connectors and controller (traces of overheating, oxidation, damaged pins), as motor failure can sometimes be linked to damaged connectors or a faulty controller. After installation, carry out a test on the stand/wheel and then a progressive test at low speed to confirm correct operation before normal use.
