Nature BIKES
Range GROMMY
Season 2022

A unique ebike that will allow you to see your children enjoy themselves like never before.

Ideal for children between 5 and 8 years old, the Grommy 16 has a saddle height range of between 43 and 58cm. It will help your little ones gain balance and begin to manage a bike perfectly. Weighing in at only 8.5 kg thanks to its 6061 aluminum frame, its motor and battery allow for up to hour’s use at full speed. Of course, that doesn’t mean that the power can’t be easily controlled at all times
