This is by no means an adult bike. It seems to be a knock-off. If you want some quality electric trike with real power than it is NOT your choice. I am so disappointed by this because I thought this would be a good way for me to get exercise without impact. We spent all the time putting it together only to have to take it apart to send it back. I feel like the description of this bike is not remotely accurate. Also within 3 blocks the tire went flat. Bpimports is impossible to get in touch with in case you need help. Beware!
