Front Coaster Brake Mad Scientist Crazy (wear a helmet)

[gone_fishin]

thank you!

it does look doable, i found this with your lead: http://www.free-coaster.com/index.html

i have to "block" travel at the driver-end, and now i know where to start

Edit - nevermind, I'm thinking the pic was the left-side of the wheel.

Okay, I don't know what happened--I meant to delete the second post I made, not the first one.

Oh well.

You guys are amazingly brilliant. I'm having a blast watching you build stuff. My mind races to fast to stop and think like you all.

Fantastic design Augie! I know there must be a way to make it work smoothly.

I did the free-coaster thing with my deviate back wheel
it worked fine
good luck !!!
I have never seen a coaster on the front before
another first for MBc !!!

i'm hoping it will be a budget upgrade that anyone could do...

anyone notice i'm beefing up S-2.1 to be the strongest bicycle i can build, regardless of drivetrain?

Long Pull Brake Levers

Long Pull Brake Levers do Exist we call them V-Brake Levers. Sheldon Brown has some really good data/info on this subject at http://www.sheldonbrown.com/gloss_bo-z.html#brakelever The key to all of this is mechanical advantage and to steal a quote from Sheldons web site "Long pull levers pull the cable twice as far, but only half as hard."

another huge breakthru! thanks!!!

we purposely want to reduce mechanical advantage of power, coaster-lock being a real concern.

Augi, would it be possible to frame mount a foot pedal to actuate the brake?

 

[gone_fishin]

possible, yes...but no way I go to a foot-front-brake...i'm crazy but not crazy

just making light, Jim H...i appreciate the input
