If you can see Cadence, Output, Calories, Speed, and Distance changing in the app while you are in a ride, but Resistance stays at 1 in the app, even through you can feel Resistance changing physically on the bike, you likely have a defective encoder wheel. This goes for the Connect Bikes ( EX-1, EX-3, EX-4s, EX-4s+, EX-5, EX-5s, EX-7s, EX-8s, EX-Pro ).
Please contact Customer Service and provide your serial number and a picture of your proof of purchase.
Manufacture warranties last a year from the original time of purchase from an approved retailer / vendor.
If you can see Resistance along with all other stats changing within the app, but you cannot feel the resistance changing physically on the bike, then use this FAQ article to make sure your motor arm is still attached:
How to Reattach the Motor Arm of a Connect Bike EX-1, EX-3, EX-4s, EX-5, EX-5s, EX-7s
If you have checked and the motor arm is attached, then we need to know when you are looking at the motor and turning the resistance knob all the way to the right, if you see the motor moving the magnet closer to the fly wheel. If you do not, then your motor may be defective. Please send in a short video along with the serial number and a picture of your proof of purchase.
If you have an EX-1, EX-3, or a bike with the serial number beginning in ECH01, then check the wires going into the console of the bike. Unplug the bike, unplug the wires going into the bottom of the console, and plug them all back in. Then, check the resistance on the app again.
If your EX1 or EX3 serial number starts with ECHEX-1 or ECHEX-3 then this last paragraph does not apply to you.
