Answer for Going up steep hills is that hard to do with this product

Can you ride the GlideCycle uphill or up a really long, steep mountain climb?
Yes you can! When the rider shifts the saddle into the climb position. You will be slower than a bike — sometimes a crawl, depending on your fitness level. But, nothing stops a GlideCycle.
Going uphill does require proper technique, a little practice and like any exercise, more effort for hills (gravity is never free). The basic approach for short hills is to lean forward in the seat, while extending your legs back and pushing off with your toes in a driving motion. For longer hills loosen the lower front strap completely allowing you to rock forward in the seat and resting your chest on the front strap. Your arms also help to support your weight. In this position you can climb longer hills. If your fitness level is really low, you can always simply stand up in the seat and walk up the hill. With a little practice and as you get into shape you can go anywhere you want. Athletic riders will find it possible to glide up any mountain. Even climb the Rocky Mountains, for miles and miles and monster workouts.
