This Sunny recumbent bike just fits me perfectly. I am 5'4" and have had back surgery with continued pain. This bike I can ride with no pain! The back is very supportive, and the seat very comfortable! I also ordered via Angi the option to have the bike put together for me, and this was wonderful! My guy arrived early and had it totally together in 1 hour!! I put my previous Sunny bike together (had it for years - I rode it to death) and sitting on the floor to do it with my back almost killed me, and it took me a couple days to get it done. What a wonderful thing to offer buyers! My guy was so polite and so neat, he was exceptionally talented to put it together so quickly! THANKS, Walmart! I'm going to enjoy my bike for many years I'm sure, with no pain!! WONDERFUL! Would recommend this bike to everyone!! Get one, you'll love it!!
