I have not used my bike yet but I trust tanga because the trac life car booster that I bought works fine they even sent one better than I ordered, I guess because it was a replacement I like tanga.

I'll glad I bought this. It was easy to put together and is much sturdier than I expected. Ever since I retired, I've find I'm sitting too much, especially since my hobbies are things like crochet. I can sit and pedal this while working on a project or watching TV. When my arms get stiff from the repetitive motion, I use the bands to loosen up. I will admit that my shoulders don't really like the hand cranks but I'm going slow and working on improving my mobility. It is light-weight, and easy to store in an easily accessible space.
