Yeah. It's fun because you can choose trails all around the world and the resistance adjusts to the terrain. Sometimes i ride around a lake near our house. Sometimes, when i want to get more miles than my husband, i ride down a mountain in France and i can get up to 43 mph! Without the app you can shift gears and it adjusts. There are a bunch of available apps for phone or tablet, some free and some pay. I downloaded about 5 free trials to choose the one i liked best.
