Im 58, fairly active. Was looking for something different than my bike. I get numbness and soreness from seats and started using an elliptical instead of Peloton. But need something for outdoors. Elliptical and standup bikes are expensive and then I stumbled onto Halfbike. Decided to give it a try after reading the reviews. Im writing this after day 2. I learned to ride straight pretty quickly, like within an hour. Im now practicing and getting down turns. Its a great bike, great way to exercise. I feel it in my legs and arms….but I feel another big benefit not discussed too much is balance. It really requires balance and helps you improve your balance. I like to ski and definitely can see how it will benefit me in that activity. I really love this little bike.
