Analysis
The V9 Ultra runs a 48V 20Ah battery (roughly 960Wh) that fully charges in 5 hours and, per the manufacturer, delivers 60 to 75 km of range. The motor produces a notably high 150Nm of torque, with four riding modes: pedal-assist, cruise, throttle, or pedal-only.
It has dual suspension, hydraulic disc brakes and a smart LCD screen showing charge level, speed and status in real time. At 50 kg, this is one of the heaviest bikes in the comparison, fitting its rugged, off-road-oriented character.
It arrives roughly 90% pre-assembled and carries a 1-year warranty. With 9 reviews and a 4.5 average, this is one of the better-reviewed models in this part of the comparison.
