What is the minimum resistance that is supported by the machine?

Our motor's total weight range is 8-220 lbs. Therefore, you can only operate within this weight range in any mode. For example, in eccentric mode, the concentric phase weight cannot be less than 8 lbs, and the eccentric phase weight cannot exceed 50% of the concentric phase weight.

How have you ensured the longevity of the pivot points?

We use 304 stainless steel and bearings of sufficient strength, plus durability tests show that there is no damage to the folding structure.

What kind of metal and finishing is the frame made of?
