Riding all my unicycles on my DIY Uni-Roller, from 19" trials to Schlumpf to 36er. Great workout when there’s no time to go out for a ride. It’s a modified bike roller with the front single roller removed. A secure, stationary structure is required to hold on to, since the rollers are free-spinning, and balance cannot be corrected or maintained by peddle pressure or body position.
Cool idea! Always nice seeing your videos!
