Looking to sell Megawheels S1 E-scooter (weight limit 150 lb) so ideal for kids/teens

It is this one:

I bought it for my wife few months back and she used it a few times and once lost balance on it so is scared to use it. The scooter works fine otherwise.

Few pics are attached.

Can give it for $150 along with a new helmet.
