Is there any advice I can get on my quingo sport. Batteries are fine. Replaced fuses to the Batteries but won't come to life. I was out on it 3 months ago and come down a dropped curb and it just gave up and died. Help me, I'm a 51 year old disabled man with osteoarthritis and rheumatoid arthritis also asthma. I use it as my one mode of getting out the house. I'm going stir crazy not getting any fresh air in my lungs.
