Lilypelle Adult Tricycles 7 Speed 20/24-26 Inch Three Wheel Bike Cruiser Trike

I purchased this bike for my uncle who doesn’t drive but likes to ride the bike to get around and in his older age he needed the third wheel . It took an extensive amount of time for me to put this bike together only to find out that it’s missing pieces! Now reading the reviews I’m concerned that the seller may not even respond to my request for a refund. I don’t think I have the patience to try and put another bike together like this and it’s just not working. I’m not even sure what parts might be missing. I just would not make this investment with this seller again. It was not worth it.
