Hate to break it to u but technicly its only 3 speed

But nice job all the same

@edwardmusaev yes your right 2 x 2 = 4, however...

Ok so you have 4 positions A B C and D. A) both sticks up obviously 1:1 ratio, B) left up right down lets say 1:4 ratio C) left down right up 4:1 ratio D) both down 1:1, but wait why is it a 1:1 ratio there different size gears as both being up?

because the speed gained by the gears on the right is equivalent to the speed lost on the left, hence 1 turn input = 1 turn output or a 1:1 ratio.

@ZaSuTeN Hating eachother because you don't have dick? ;( Cry baby. Cya.

[ZaSuTeN]

Put your dick in it.

@geekymgee no, if you look closely up up and down down has the same speed transfer ratio. i would love to tell you why but i really don't want to sit here typing all of this up, look i learn this in my manual trans class 1, 2 and 3 and i still remember how confusing all that info is about gears and gear ratios so either take my word for it or don't

[geekymgee]

@lordlong up up

down down

down up

up down

all four of these have a different ratio, however slight they may be, and thus he has four speeds, regardless of difference in mph

[lordlong]

@geekymgee he's talking about the gear speed ratio, not math. if you only get 3 ratios for the 4 different gear combos it is only a 3 speed since 2 ratio are the same, it's like how a transmission in your car work.

now I don't know if the gear set gives him 4 ratio or not, but regardless of how many gear combos he has, the amount of ratios he can produce is his gear speed

[geekymgee]

@wolgran20 wrong, 2 levers w/ 2 positions.

2x2=4

your math must be fucked up

[KatzOhki]

Awesome! Great job. Now just invent a Lego Technic synchromesh and we're good to go.

OMG it has an optical illusion from 0:25 to 0:49 that broke my brain at first few moments. It seems that the gears on the second rod from left rotating in different directions

[wolgran20]

@dilster97 Its explained above ^^

sure there is 4 stick positions but there is only 3 different gear ratios because 2 of the positions have the same ratios

[dilster97]

@wolgran20 how is it 3 speed please explain to me
