This mechanism is a life altering device for some. It’s the GlideCylce. And for some people who have been wheelchair-bound, are obese, or otherwise injured, this cycle has given them a way to use their legs again. Body weight is supported by an ergonomic saddle that holds the pelvis is a specific position that allows the rider to walk, run, or glide. It’s kind of awkward-looking in these photos, but there is a demo video that shows how it works and what it looks like in motion. Their website shares stories of many people who have used the GlideCylce to loose weight, reduce medications for pain, and improve balance, strength, and posture. They are set to release smaller sized models for smaller people and kids.
