The INMOTION RS III brings together dual-motor power, Samsung 50S cells and adjustable handling in a high-performance electric scooter. Its speed story starts with the drivetrain, but braking and chassis control complete the picture.
Experienced riders seeking strong acceleration and adjustable handling who are comfortable managing a 58kg scooter.
Not for:Beginners or commuters who need a lightweight scooter to carry upstairs or onto public transport.

1. Performance: What Makes It So Fast?
The RS III pairs two 2200W-rated motors with 8800W of combined peak power. The US version has a rated top speed of 75 mph (120 km/h), with a stated 0–30 mph acceleration time of approximately 3.5 seconds.
Top speed and acceleration describe different aspects of performance, while rated and peak power are distinct output measures. Together, these figures establish the scooter's performance focus; actual results depend on riding conditions and regional configuration.
2. Battery: Why 2880Wh and Samsung 50S Cells Matter
A 72V, 40Ah battery pack combines 2880Wh of capacity with Samsung 50S high-discharge cells to support the motors' power demand during acceleration and climbs.
Rated maximum range is 100 miles (approximately 160 km), not range at maximum speed. Actual range varies with rider weight, speed, terrain, temperature and tyre pressure. The BMS monitors charging, discharge, current, temperature and cell balancing.
3. Handling: Putting the Power to Work
Selectable single- or dual-motor drive and four riding modes let riders adjust power delivery. The scooter ships in Parking mode, with riding settings released progressively through app activation. Release the throttle or stop before changing modes.
The four-position chassis offers ground clearances of 183mm, 213mm, 253mm and 303mm. It works alongside 13-position adjustable hydraulic suspension and an external steering damper designed to suppress handlebar oscillation.
Front and rear four-piston hydraulic brakes use 160mm discs and work with regenerative motor braking. These systems support braking and handling; they do not remove the risks of high-speed riding.
4. Cockpit: A Cleaner, Touch-Based Interface
A 4.3-inch colour touchscreen brings speed, battery level, mileage and drive settings together. A thumb throttle and swept riser handlebar complete the controls, while the app provides activation, locking and adjustments for acceleration response, zero-start, cruise control and lighting.
5. From Unboxing to Your First Ride
Follow the manual to assemble the scooter, check the fasteners, wiring and folding safety catch, then complete app activation. Keep the original packaging for at least 30 days. Begin in Eco mode in an empty practice area with someone present, wearing a helmet and full protective equipment; do not start in X mode.
6. Safety: The Limits That Matter
Reserve high-speed riding for permitted closed courses. Do not ride in motor-vehicle lanes, on highways or on main mountain roads. Avoid abrupt steering, one-handed riding, passengers, headphones and phone use; do not ride while pregnant, on stairs or over kerbs.
Do not ride through standing water, regardless of the stated IP56 rating, or touch the motors immediately after riding. If the scooter tips over, return it upright and follow the manual before restarting.
7. Everyday Care for the Long Run
Use the original charger and follow the manual's charging-location guidance. Never charge with moisture in the port, and close the dust cover afterward. Check tyre pressure before every ride; the stated range is 2.5–3.5 bar. During extended storage, avoid leaving the battery fully discharged and recharge every three months. Consult the manual for fault-code diagnosis rather than continuing to ride with a warning.
8. RS III vs. the Previous RS: What's Changed?
The key performance changes are concentrated in motor output, battery cells, braking and steering:

9. Questions and Answers
Q1: What Is the Rated Top Speed of the US-Version INMOTION RS III?
The US version has a rated top speed of 120 km/h, approximately 75 mph.
Q2: What Battery Does the RS III Use?
It uses Samsung 50S cells in a 72V 40Ah battery pack with a capacity of 2880Wh.
Q3: Is the RS III Stable to Ride?
Yes. Its external steering damper reduces handlebar oscillation, while 13-position hydraulic suspension and a four-position chassis support stable handling.
Q4: Is the RS III Suited to Closed-Course Performance Riding?
Yes. Its dual motors and four-piston hydraulic brakes suit experienced riders on closed courses. Full protective equipment is essential.
