Diagonal Drive

[bicycleguy]

I built a diagonal drive (retro direct) bike, the forward gearing is 44-16 and when you backpedal you get a forward gear of 44-22. It's pretty weird to ride at first while your backpedaling and going forward but then it seems normal, I still need to figure out how to wheelie while pedaling backwards

Huh?? :?

wait wait wait, so you figured out how to make the bike go forward by pedalling backwards?

I could ask why? but whats the point in that! lol

Awesome! but it hurts my brain :lol:

I like it. I saw Retro Direct a couple of years ago but never got into making one. Good to see you were able to get the chain figured out with out having to change the chainstay. Is your 22t a stock freewheel?

i pulled a muscle in my head.

The 22T is a Dicta BMX freewheel, I tried other brands (ACS, Shimano) but they had a lip on the end to for the freewheel tool to remove them, Dicta freewheels don't have a lip and they're threading all the way through so you can thread a bottom bracket cup into one side then thread the rest of the freewheel on to the hub.

Did you consider doing the fabrication to put a larger cog on? You have some hills in Portland that a 27 or 34t would be handy on.

For those whose mind is bending, here is a diagram.

The gearing is pretty good but I did think about fabing a larger cog on to the freewheel for more of a difference between the two gears.
