"A scooter built for its low price, with a range claim that appears to defy physics."
The 'Powerful 350W Motor' is standard entry-level power. It's adequate for flat ground and light riders, but will labor on hills and feel sluggish for heavier adults.
This scooter is for someone needing a 'last-mile' vehicle for a very short, flat commute who values an extremely low initial cost above all else. If you need to get from the train station to the office 2 miles away, it is a functional, disposable-class tool.
Anyone needing to travel more than 5-6 miles reliably on one charge should look elsewhere. Riders in hilly areas or those weighing over 200 lbs will find the motor frustratingly weak. The solid tires make it a poor choice for anyone riding on imperfect pavement.
