Sunny Health & FitnessIndoor Intensive Cycling Exercise Bike, Adjustable Cardio Training Exerciser w/Emergency Brake for Home, Optional Free SunnyFit App Bluetooth Link + Electromagnetic Resistance

As soon as I put it together the resistance would not change. It is adjusted electrically with the led display knob, so there nothing I could do to try and fix it. I’m sending it back.When I took it apart I found the connector wires crushed, I can’t believe the company sent it to me this way. Very disappointed.
