This is a set of the left pedal and crank arm for the Haiger fitness bike. It is not the main unit. The screw wouldn't fit, so I bought the parts new, but they became unnecessary because they couldn't be used due to a defect in the main unit. Pedal / Left / HG-QB-J917B Crank arm / Left / HG-QB-J917B I tried to install it once but couldn't, so it's almost unused, but it's not new, so please understand that point. To prevent trouble, we decline price reductions and dedicated holds.
