It's the same principle as standing a bike upright by positioning one pedal so that it's (1) rotated down and slightly back from bottom dead center and (2) resting on a curb. Many of us learned to do that for decades. The ACC pedal kickstand just eliminates the need to use a curb. |

Yes, but wouldn't a slight bump or even wind topple the bike without a locking crank? It does not appear stable enough to trust a carbon bike with.
The best kickstand is the double old-school-motorcycle kickstand. Anything short of that is going to be a compromise. Just a question of how much risk the rider is willing to tolerate. |
Difference being, from a traditional bike kickstand, the ACC is attached to an unlocked crank.
it does offer more surface area but without a locking crank, it appears to me that it is a poor design. |

Sure, but with an incorporated locking crank mechanism, it may be as stable and functional as a traditional kickstand.
dunno. But if I get time off this summme I’ll attempt a build. |
I have to hand it to Mike, that he actually discussed the prototype idea versus the watch-band guy and the bike-lane separator guy (may be one in the same) who just teased us with an idea but never even hinted at a design. The teasing thing does remind me of a couple of short lived relationships in high school. :D

If? was under the impression that citizens of Canada were entitled to a minimum of two weeks off. Or did that move to TX actually happen after all? :lol:

Way too complicated. Even the ultra simple and cheap pedal thing in post #15 is not already on every commuter.
|
Why reinvent the wheel, so to speak? Why not just buy a conventional, bolt on kickstand, which attached to chain stay/s, like we had as kids?

Also a bad idea for carbon, which is probably obvious to all. And even for chro-mo steel chainstays, as someone at Surly explains very entertainingly on the company's website. |

Im not interested in how to improve a kickstand on aluminum bikes, I want one on my carbon that works as efficiently. |

What we want and what the market will accept is often conflicting. |

The reason it’s not on every commuter is more likely due to the fact that it doesn’t work well since the mechanism is not tied to a locking crank.
But we’ll be eagerly awaiting your finished product, Fiddy, if you get some time off, that is. |

Whatever. You might or might not have known. Plenty of people here who consider themselves knowledgeable about bikes don't know better. Spelling it out for them doesn't harm the rest of us.

Look, ma! No kickstand, and no locking crank. (And no lock.)

Sounds like a poor idea. I mean loads of extra complication to replace a $15-30 part and won't actually work without more parts and more stuff to fail. I will just stick to my rear wheels rubber or a normal kickstand. All companies need to do is put a 18 or 40mm bolt spacing at the rear and you can mount a whole lot of kickstands that are out of the way.

First, do a search for similar ideas on USPTO.gov (US Patent and Trademark Office); My dad had an idea and was going to spend money to patent it, I said hold on, the next day I handed him printouts on a half-dozen different versions of the same thing already patented. He thanked me for saving him the money.

If I just had to have a kickstand, i might give this a try.
