Peloton bikes are wonderful exercise machines that bring interactive workouts to your home. With the SHIFT Smart Trainer, you can use Zwift on your bike. It fits on the resistance knob of your bike and connects via Bluetooth to adjust your resistance to simulate the grade changes of the route you are taking.
The SHIFT Smart Trainer has a convenient display for resistance calibration. It goes on and comes off easily. This project is getting funded on Kickstarter at this time.
