      The scooter was very easy to assemble. We are so pleased with this product. We would highly recommend it to our friends.

      Got my life back

      Took my initial outing on my EV Rider yesterday. It was so liberating! I was out and about for over 3 hours and still had lots of battery life left. Comfortable and compact, easy to operate. I'm 5'2" and 130# and it's the perfect compact size for me. Not for a bigger person though.

      Met and exceeded my expectations.

      Easy To Assemble

      Very east to assemble (less than 1 minute--- I am a 68 year old woman and i do it entirely by myself! The chair is small and comfortable. My mother is 100 and feels she has NEW FREEDOM with this new chair. I, too, feel like there is new freedom. She has adapted very well with the joy stick,, which is very sensitive. This chair can move in a circle on a dime! I would highly recommend this as a chair that can be used in a facility to get around, but also very easy to load in the car and go to another destination!
