Frame designed for mountain biking

Our engineers have designed a new strong, light, dynamic frame made from aluminium. It's designed for tackling any obstacles when out mountain biking. Hydroformed 6061 aluminium tubes.

Changing gear

Changing gears: A SINGLE CHAINRING LIKE THE PROS!The single chainring is easy and efficient to use:

1 chainring (32 teeth) and 8 speeds (cassette 11/34 teeth): 11-13-15-18-21-24-28). With just 1 shifter on the handlebar, changing gear is child's play. The trigger lets you shift up and down between gears with just one finger.

The gear ratios let you accelerate on the flat and tackle climbs more easily, without compromise.

Don't be scared of riding downhill!

Effective, progressive braking thanks to the front and rear hydraulic disc brakes.

The disc brake acts on the wheel axle to deliver powerful braking under any conditions (dry, wet, muddy, etc.).TEKTRO Junior 160 mm disc brakes

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).
