The Bike came in unassembled kit form, which required several hours to assemble. I followed the instructions precisely, but I was unable to release the tension on the pedals, which are very stiff to rotate. The manual tension controller does not work.
I dis-assembled the upper support arm and checked everything was connected. Everything was connected correctly, but the pedals are still very stiff.
I hope you can come to my house and solve the problem, or replace the machine.
