What's the difference between this kids' e-MTB and an adult one?
This electric mountain bike has a special frame designed to fit kids aged 9 to 12. It's equipped with the same motor and battery as the adult E ST 100 bike, but the assistance modes have been adjusted to be smoother and more progressive. The 26" wheels make clearing obstacles easier while keeping the bike comfortable and easy to handle. Last but not least, the positioning elements are designed around the size of kids' bodies (handlebar width, saddle, and crank length).
