S2 Kids Electric Dirt Bike — 250W / 450W / 600W, 13–25 km Range
The S2 is the kids platform: one frame and a 51 cm seat in three drive levels, so a rider from four to eight years old — 100 to 120 cm tall — fits it from a first bike to a first competitive season. Parent-set speed modes (6 / 10 / 15 km/h on the entry build, 10 / 16 / 25 km/h above it) cap the bike as confidence grows.
All three builds share the chassis and the 510 mm inverted front fork. Moving up buys a brushless motor (450 W or 600 W instead of the 250 W brushed entry), hydraulic brakes, a larger pack and, on the 36 V / 7.8 Ah flagship, 14-inch wheels, a 55 cm seat and a 75 cm wheelbase. Range runs 13 km to 25 km.
Modular by design — drivetrain, braking, wheels, battery and branding can be specified to your market, up to full private-label customization.
