Ridstar Q20 – Urban Muscle Meets Off-Road Grit.
The Ridstar Q20 blends moto-inspired styling with
everyday practicality. A punchy peak 1 500 W brushless rear-hub
motor and removable 48 V 15.6 Ah (720 Wh) lithium

30 mph / 48 km h⁻¹, while dual suspension lets you float over
potholes, sand, snow or single-track. Go 30 mi / 48 km on pure
throttle—or up to 75 mi / 120 km* in PAS mode—and recharge in
just 4 – 6 h.
Hydraulic dual-disc brakes, a back-lit LCD dash and an integrated
head-/tail-light system keep you in control day or night. With a rugged
aluminium frame rated to 330 lb / 150 kg, the Q20 is
built for commuters who play hard on the weekend.
