A real WILD idea: A rear wheel up front?
I was looking at some old parts in my shop, and saw this old rear wheel stashed in the corner. (I don't have a frame for it, so it's been sitting awhile.) Then I saw a picture of a bike with a wild looking large-hubbed front wheel, and thought, "Could I mount my old (120mm) spacing rear hub up front on a new fork (aren't they 120mm spacing)???"
Then I really started thinking weird - could I make the coaster brake work from a brake lever cabled to a piece of chain on that "front" wheel???
Just thinking. I like to try different things.
I know - I have way too much time on my hands.

Most front hubs are 100mm. But don't let that stop your thinkg.

You probably saw a bike with a front drum brake. Anyways, you need to look up the Surly Pugsley.

As far as getting the coaster brake to work, I suspect that the cable pull would be too long and coaster brakes require a lot of force be applied to get much stopping power. Made that way as back pedaling can provide a lot of force and you would not want a rear brake that was too sensitive.

Coaster brake on the front wheel is a bad idea. Those things are pretty cumbersome and you need good brake pressure modulation on the front if you want to avoid going over the bars...

The only way I can think of to actuate a coaster brake by cable is through the driver, and I Think the amount of cable pull required to do this while still getting any kind of leverage would be well beyond the capacity of any available brake levers.

I thought MTB forks were 120mm??
You're right - I'd need a stronger brake lever than is available. I guess I'd have to make some heavy duty steel lever. Even then, though, I'm sure the front brake won't win any stopping distance awards!
But the thought of having something like this! I'll have to cogitate on it for awhile.
