Electric Balance Bikes — HP126E (20″) & HP125E (16″)
Powered balance bikes with hub motors and two riding modes — the factory's documented pair, published with both specification tables.

The HP126E is the larger of the pair: a 20-inch electric balance bike with a 500W 36V BLDC hub motor (800W maximum power), a 36V5Ah lithium battery, a 6061 alloy frame, aluminium one-piece wheels, front and rear hydraulic disc brakes (160mm front, 140mm rear), and a Manitou J-Unit Machete front fork with 80mm of travel listed in its table. Its speed listing is modal — a high/advanced mode of 40 km/h (25 mph) and a low/training mode of 20 km/h (12.5 mph) — with a range per charge of 12–17 km, an adjustable 580–680mm seat height and a 17 kg net weight.
The HP125E is the 16-inch step down: a 350W 36V BLDC hub motor (500W maximum), the same 36V5Ah lithium battery format, a rear mechanical disc brake (140mm), high mode 30 km/h (20 mph) and training mode 15 km/h (10 mph), a listed range of 30 km per charge with the manufacturer's own note that mileage is affected by rider weight, speed and venue, a 540mm seat height and an 11 kg net weight.
The two-mode speed listing is the commercial heart of both models: a training mode for learning and an advanced mode for progression, on the same machine. Both tables follow in full — note that several rows in the source tables (gears, maximum load capacity) carry no value and are omitted here rather than filled in.
