Oh my goodness, were you born in the 1800's? Go away troll.
Clearly something about this is bothering you considering how attached you are to this thread. Were you dropped in a seniors warmup run this week?
Rather than wasting my time trying to teach you some basic science, I'll have to teach you in my video.

I want to see the start un-aided on flat terrain in a 70X11.
I predict as much success as Elvis Presley's vain attempt at expulsion via the Valsalva Maneuver on the toilet as propulsion on the OP's mystery bike to 50 Mph from a standing start.

We have to understand that the OP has obviously unlocked some sort of God Mode, because he routinely puts out more power than any other human on the planet. He's probably got the power to throw a burnout with that 70-11. Anxiously awaiting the thread about what tires to to use to put down the power without shredding.

You have to admit, however fast or slow he might be as a rider, he is a pretty good troll.

And he is faster than any world-class track sprinter .... because of his big ... cranks.

You already know these geezers are more so hoping I don't hit the 50 mph, rather than truly believing it can't be done.
Whether I do it or someone else...I'd love to see that "stupid face" look when it happens.

if you can hit 50 mph on the flat, unassisted, without a tailwind, on a an unfaired diamond-frame bicycle, you will set a new world record. Why wouldn't anyone want to see that?

Anyway ... you like to boast a bit, others like to roast you for boasting. We all see what's happening here---it's all good fun. I am eagerly awaiting the video, the strava ... umm, how are you planning to verify that you actually did this, should you do it?

How are you measuring your speed? I saw that you had another thread asking about the most accurate method of measuring your speed, so I'm kind of lead to believe that these measurements may not be the most accurate. (Admittedly though, I'm reading your posts in the tone of a boastful weightlifter type, so I might just be the ******* here.)

Despite my scepticism of your claims, I do want to call attention to one point you made that nobody else commented on, and I think you're totally right. We shouldn't limit ourselves to a strict idea of what a bike can be and what it can be used for. I get the impression that most of us here, like you said, see cycling as somewhat of an endurance exercise with elements of adventure and exploration. It seems like you are more interested in strength building and the excitement of going super gosh darn fast.

I may not identify with the desire to make a bicycle into a squat machine, but who is anyone to say what a bike can be? Whether you truly are some sort of as-yet-unheared-of speed cycling protege as you claim, or just a dude who likes to go fast and screw with others on the internet, I think its cool that you seem to have found enjoyment in an aspect of cycling that doesn't have as much mainstream appeal.

More power to you (no pun intended)

You're actually claiming that being heavier and taller makes you faster than the best professional racers?

You're going to need a lot better proof than a homemade video, because you have apparently set everything known about bicycle physics on its ear. 6'0" is considered tall for a professional racer because of the aerodynamics. None is 6'5" , and it's not because tall people would have some sort of unfair advantage.

I usually take people's performance claims on this forum at face value because lying anonymously is too silly to contemplate, but you are in "I leap tall buildings in a single bound" territory here. Extraordinary claims require extraordinary proof.

Thanks for your reply and the extra information, tmtt. Can you post a pic of the bike? A pic of you would be nice also. You can crop your head if you prefer to maintain anonymity. I totally understand that not everyone wants to be a famous, world record holding pro cyclist.

Well that certainly makes perfect sense.

Same here. Even if you don't hit your goal, remember that the only thing worse than failing is to not even try.

How is 50 a world record?

I thought some lady just did 127 MPH?

Yeah, she was riding behind a special vehicle and had to be towed up to 25mph, because that custom-from-the-ground-up bike cannot be physically pedaled from a standing start.

Oh, and it’s 183.9mph. She annihilated the old record, and if you look up “world record speed bicycle” Fred Rompelberger still comes up as the first results, and he did 167mph. 24 years ago. Google might be sexist.

I have so far been unable to locate a world record for unassisted, unfaired upright bicycle. The world record for upright, unassisted, faired vehicle is just 51.28 mph, and was set in 1986.

Recumbent, unassisted and faired is 89.58 mph.

With that on your bike, you'll go fast enough to experience time dilation.
