Algupära

Dualtron is the flagship line of Minimotors, a South Korean manufacturer (Minimotors Co., Ltd., founded in Seoul) that helped define the modern high-performance e-scooter category. The Dualtron family — 'dual' for its signature twin-motor drivetrain — earned a cult following among enthusiasts for building genuinely fast, long-range machines out of aviation-grade aluminium at a time when most scooters were flimsy last-mile toys. The Ultra arrived in 2017 as a purpose-built off-road monster: where the earlier Dualtron III leaned commuter, the Ultra bolted on beefier 2700W-class motors, a larger 2072Wh LG pack, and huge 11-inch knobby tyres, making it one of the first mainstream scooters you could genuinely take off the tarmac. It became the reference point for 'off-road beast' e-scooters, and Minimotors kept the name alive across a 72V Ultra II (2021) and a 40Ah Ultra 2 UP (2024).

Aku: 60V 34.5Ah 2072Wh, LG Li-Ion cells
Sõiduulatus: ~74 mi / 120 km manufacturer quoted; realistically ~50-90 km depending on speed/terrain (single-wheel eco extends it)

Max koormus: ~150 kg / 330 lbs (some sources ~120 kg)

Verdikt

+Tugevused

Genuine off-road capability — wide 11in knobby tyres plus torsion suspension eat bumps and loose surfaces
Strong dual-motor acceleration and ~80 km/h top speed with a big 2072Wh LG battery for long range
Aviation-grade aluminium build is famously durable, yet lighter than many comparable Dualtrons

−Nõrkused

No kickplate and reported stem/handlebar wobble when folded/locked — control suffers at speed
Braking and lighting feel underwhelming for the price; original Ultra has no ABS
Very long ~20h charge on the stock charger (fast charger is a paid extra) and heavy to carry up stairs
