Yesterday I volunteered at a club sponsored ride and one of the club members brought her Kickbike. After registration was over and we were waiting for the riders to start returning she let all of us take a spin on her bike. Wow! Does that thing ever use different muscles. I'm glad I was wearing sandals and couldn't go too far.
She said she uses it for cross-training and her longest ride to date is 15 miles. Anyone else had a chance to give this things a try?
