Hi NormK,

I saw the bike lift also a double scissors. Looking on the scaling and based on my calculation at 60 degrees, max height of 87cm and min height of 35cm, with vertical travel of only 52cm, the arm is only 30cm long. When you use 60cm arm with 55cm between pivots, at 50 degrees angle, the vertical travel is 84cm plus minimum height of 10cm-16cm (for castor wheels and base frame), the total height would be 94cm-100cm. Good choice of arm length. You only need the car scissor jack to push by at least 15cm to raise to 1m height.

Cheers,
