Grommy’s motor is all-new, specifically designed and produced to be neat, small, lightweight and reliable, and putting out just the right amount of power to make Grommy fun, safe and the best way for kids to learn balance and handling.

The slim, brushless, max 250W output motor’s low, centrally-mounted position is an important element of Grommy’s handling. Our integrated approach with e-bikes – including the super-lightweight Carbon Crafty RR SL – informs the design and positioning of the motor, drivetrain and battery which are shared across both size Grommy models.

Mastering the three-speed controls is child’s play. The learning starts on the first setting, ‘Balance’ (max speed 8.1km/h) and the grins get broader on 2, ‘Fun’ and and 3, ‘Advanced’ (max 17.7km/h). Or you can turn off Grommy’s motor and kids can use it like a traditional balance bike. 

For Grommy we also decided to make our own bespoke batteries. They’re lightweight and we designed them to be really easy and safe to swap over. Because each battery unit delivers a run time of up to 60 minutes (depending on which power mode the kids ride in!) with a full charge taking just 60 minutes, a simple swap-over keeps the Grommy going as long as your youngsters can. The motor and battery are IPX4-rated water-resistant and there’s a custom plastic protector for the motor and drivetrain to keep little feet safe.
