First I made my own, while braking, rubber roller broke off and decided to get the real deal. Great construction, light, easy to work and balanced for optimal performance. Great exercise for the whole body. I'm 52 years old and find that the combination of upper, lower and core work is very balanced and provides a cardio on long rides (.3 miles) and great anaerobic workouts going up steep hills For us old guys, the stick provides great braking power to keep you in your own personal comfort zone (slow for us old guys).

Got my kids the sticks and they love it.
