Hey don't take offense, I singled no one, majority means over 50%, which means bigger than either your or my one butt, America is up to 63.2% at last count, stats are used in predicting monetary return, if there's more fat people you HAVE to take that, and their behaviors into account.I am neither fat nor lazy, but due to a disability, I can no longer pedal a bike very far. I still ride motorcycles, both dirt and street. And I still love riding bicycles, as long as I don't have to pedal them.
Syphonza is partly on to it.You have to remember, we all are WAY into this, but the majority of Americans aren't even WAY into bicycles, better put, just because you're jazzed about something doesn't mean anyone else is, or ever will be regardless of how cool.Examples in other fields, musical fields look at the Yamaha G10C and the Zeta Mirror-6, unbelieveable things, ultra cool, ended up costing the end user $10,000 for one unit, few sold, many pissed investors.
Do you gamble?That's what's it's about, for the most part you'll see add-ons but no innovation-invention, it's not worth it at this point in America.
OK the speeds you want to go on a bike, you need a DH or Freeride, disc, or drum brakes, sealed bearings.Common bicycles won't handle high speeds for long.You're going to have to build it all yourself, the only way to do that is either find, or have made, a small wankel, but remember wankels are inherently fuel wasters.Other than that crazy gearing systems, or find and old Sachs bike, and have a machine shop breakdown the engine, and create a sportier one in the same case.
