Using Amuro’s calculated circumferences and the gear ratios of the EVO drive it is not that difficult to complete the post above:
[size=120]Strida EVO with 16" wheels
(tyre size 16 x 1,5)[/size]
Gear inches:
in low gear: 16" x 100 x 0,787 ÷ 30 = 42"
in middle gear: 16" x 100 x 1 ÷ 30 = 53,3"
in high gear: 16" x 100 x 1,257 ÷ 30 = 67"
Metres of development
in low gear: 1,185m × 100 x 0,787 ÷ 30 = 3,11m
in middle gear: 1,185m × 100 × 1 ÷ 30 = 3,95m
in high gear: 1,185m × 100 × 1,257 ÷ 30 = 4,97m
[size=120]Strida EVO with 18" wheels
(tyre size 18 x 1,25)[/size]
Gear inches:
in low gear: 18" x 100 x 0,787 ÷ 30 x = 47,2"
in middle gear: 18" x 100 x 1 ÷ 30 = 60"
in high gear: 18" x 100 x 1,257 ÷ 30 = 75,4"
Metres of development
in low gear: 1,315m × 100 x 0,787 ÷ 30 = 3,45m
in middle gear: 1,315m × 100 × 1 ÷ 30 = 4,38m
in high gear: 1,315m × 100 × 1,257 ÷ 30 = 5,51m
