Perfect for children between 5 and 8 years old, the GROMMY 16 has a saddle height range of between 43cm and 58cm. This is the bike to help your budding groms (little riders) to gain balance and begin to master riding a bike. Weighing in at only 8.5kg, thanks in large part to its 6061 aluminum frame, its motor and battery are good for an hour’s fun flat out. Of course the power can be easily controlled at all times.
