about 4003 mph, it helps running 2000 gear inches

my beyblade is a fixed gear

Over 9000!

The fastest speed you've ever recorded on rollers is 32mph? I've hit 56.2mph for a few seconds, spinning at just under 200rpms.

Although those were the nicest, smoothest rollers I've ever ridden on.

Did you say "let's see if these bastards can do 90" right before?

I rode by one of those LED signs that tell drivers how fast they're going and it told me I was doing 25mph. Flat and I'd pretty much spun out on my freewheel. Other than that I have no idea.

Great SCOTT Marty! He clearly dialed it up to 1.21 Gigawatts.

i hit 26 sprinting on a flat the other day on my 42x17, 64.9 gear inches. There was def a tailwind, but it wasn't crazy. Downhill on the same gearing I've done ~32 (and kept in control).

I've definitely done faster on both but just recently got a bike computer and haven't tried sprinting and I no longer live near hills (I lived in VT, now I live in DE)

I doubt anyone here is going over 30 mph on the street [flat street anyway]

I've hit light speed once or twice.

30mph sprint isn't all that crazy (if they're talking purely as a top off and not being able to hold it)

ps: love your blog

johnprolly, you blog? Where?
ps. I love that darkthrone is your avatar.

something around 32 or 33 mph. 42x17 on 700x23's. I feel like I could spin a little faster, but I certainly couldn't hold it for very long.

i'm around downhill
and
flat was 28mph

I'm willing to bet most people who ride moderately frequently can sprint over 30 easily.

edit: most men at least.

Hmm... I don't know cause I don't have a computer on my fixed-gear bike. Why would I?

The only thing that matters is it gets me from home to work in under 15 minutes, or faster than any other form of transportation.

As I posted above, I've done it. It was a peak speed obviously, not a sustained effort. And it's not a superhuman achievement: It's just under 150 rpm with 69 gear inches and about 600 watts. (according to this power calculator: http://www.kreuzotter.de/english/espeed.htm)

**** dogg when i was living in the bronx i'd haul down 5th ave at high speeds. spent a half a mile drafting a motorcycle at 34mph earlier this summer.

easily my favorite bike related blog (up there with bike snob... but I appreciate him more for the humor)

As others have said, I've done it... At my ratio it's hard work and I can't sustain much over 25mph for long. If my legs are warmed up it helps - I can't (and don't want to) really spin up much past 22/23mph when cold. While certainly not sustainable I can and do hit 30mph on occasion without hills. C'est possible.

31 mph on flat ground running 48/17, higher than that on a velodrome with different gearing and faster still going down a long hill.

:hay:

well, i once went to plaid.

58kph

but

104kph on my road bike

This guy is dead on.
