The big news here will of course be the motor. On a traditional e-MTB the motor is an assist. This means that as you pedal, it adds power on top of what you priovide. On a balance bike, no pedal input is possible so instead Mondraker have designed a 250W brushless motor with a throttle input. The throttle is controlled by a grip shift and has three power modes – ‘Balance’ (max speed 8.1km/h, 5mph), ‘Fun’ (max 12.1km/h, 7.5mph) and ‘Advanced’ (max 17.7km/h, 11mph). Yes, that’s right, 3-year-olds with a throttle powering themselves along at 11mph. It can also be turned off it riders want to use the Grommy without the power. The motor has a 40-60 minutes run time and a 60-minutes full charge time.

The kids riding these bikes won’t be as strong as their adult counterparts so Mondraker have tried to make the Grommy as light as possible. They have a good previous record here with their Carbon Crafty RR SL e-MTB coming in at under 20kg. Using mostly components designed in house, these bikes tip the scales at 8.5kg (18.7lb) for the Grommy 16 and 7.5kg for the Grommy 12 (16.5lb).
Grommy will be available to buy from regular Mondraker dealers starting from an estimated retail price of 749€ and comes with a 2-year warranty. More info, here.
