I have owned a Terratrike Rover back in 2011 and my daughter is riding it now. They make great, low cost trikes with high seats (above 16") which I need. I have since switched to Sun Seeker Electro-tad which has motor assist and a throttle. I'm getting older and the hills sometimes kill me. Also, if I experience a problem, I can go full motor. Range is around 30-50 miles on a charge depending on how you use it. Terratrike also makes a head rest, but it does lack in cushion. Terra Cycle makes one as well that is a lot softer, but they have been out of stock recently. Working on getting their pad replacement that fits on the Terratrike mount by going through Laid Back Cycles out of Sacramento. They made one for the owner. Trikes are the best. I bought mine from Utah Trikes which is the largest trike dealer in the world. They do a lot of custom work and can fit anyone. Check out their website @ utahtrikes.com
