Kurt Kinetic's Road Machine Trainer features an automatic resistance unit that adjusts as you change speeds so you get a true outdoor simulation. With a 6.25 lb. flywheel and a sealed fluid chamber pushing back, you get a natural resistance feel and a lower operating temperature for consistency. When it's time to store or transport the unit, simply fold up the legs and tuck it away. And, thanks to the 2 1/8-inch roller, tire wear is reduced significantly.
-Compatible with wheels measuring 16-29 inches, 700c, 650c, and tandems
-Wheel sizes less than 22-inches require Kurt's Small Wheel Adapter (sold separately)
-Folds easily for storage
You need a trainer that runs smooth, no herky-jerky pedal motion. This one glides smooth. Nice heavy stable base. Not the cheapest, but why buy a cheap one that will barely get used? This one is a joy to ride and is very comparable to riding outside. I am asking 150 or best offer for the bike trainer. It is in great condition.
