Here's what people say about Zize Bikes


"Thanks so much for offering bikes like this! I am so glad that you are providing these bicycles. My son, who the bike is for, is mentally challenged and he loves to ride his bike. Bikes were never big enough so we would go through lots of tires, rims, and frames. Again I thank you."

― J.L​​​​​​​.


"Buying a bike that was able to support me was a major step in getting more exercise and living a better life, plus it's also helped me get to places without walking or taking a bus. I've lost over 100 pounds since I purchased my bike."

― Aprille Morrison


“I just had my first ride on mine. The bike performed beautifully. And it was a thrill to be able to ride again after many years of not being able to. I can't properly express the degree of my gratitude to Joan and the community Zize serves.”

― Sean Gallagher
