43 kph, mountainbike, somewhat tipsy, downhill, 21st gear

~50 km/h on rollerblades! Hanged on to a driving car for about 100 meters. Scariest ride EVER!

I fell down a hill once pretty fast, if that counts.

I am really not sure.

When you're not sitting behind half a ton of metal, anything above walking speed feels like you're in warp drive.

Not if you can calculate and present to us your average velocity.

26mph (41.8 kph) downhill on a mountainbike on a hill in a park near me. had a speedometer and all :)


edit: yayyyy!! 12k posts! :D :fluffle:

Umm. I have no idea. I've never taken any notice to something like that. I probably never will either.

Not if you can calculate and present to us your average velocity.

Ah, I was a bit busy at the time, so I didn't really take any measurements. :(

Is a Flying Fox Human Powered?

Tell me about it! It was great fun tho... :cool:

30 miles an hour, downhill on a mountain bike. Broke the speed limit and all :p

55 kph on a hybrid. going downhill with a tail wind. I am a fuckin' leaf on the fuckin' wind.

Same here. There was this huge hill on my way to college, I used to free wheel it all the way down every morning - 2 miles in 5 minutes! That was so damn cool! Kinda freaky though when you pass out cars then hit that huge pot hole some prick left behind the night before just so he could get home to some good lovin'. The speed limit was 30 there, so I know I did at least 30, probably a little more considering I overtook cars...

Hi,
I was riding my bike down a hill with a huge bag on the back.
So I made some more than 70 kph on my bycicle computer.
It was pretty fast, thou.

If it counts, on my skis I have been faster than 90 kph, on a speed test run. Probably even faster other times but there is no speed indicator on my skis...:D

Uhh...probably about 5 MPH on a sled. But when you think about it, going downhill on something isn't human-powered, it's gravity-powered. For all intents and purposes you would have to be going on a flat surface for it to be truly your effort.

I've never recorded my actual speed, but I can keep up with traffic on my bike on the highest gear. I'm guessing that's somewhere around 30mp/h.

Really don't know. My snowboard isn't that fast (to short and beat up). Pretty damn fast on a bike I bet, probably somewhere in the 40kph range. Now if we could count sailplanes as human powered (can we say the notion of gravity was a human concept:confused: ) than about 100mph after recovering from a spiral dive:)

This is actually a common misconception. The inertial dampners of a starship prevent you from sensing more than the slightest motion. If they were not operational, you would be smashed into a one millimetre thick organic paste on the front of the inside of whatever part of the ship you're in.

...

On a serious note: 60 KPH, mountain bike going down Mount Evans, one of the tallest mountains on the North American continent. EEEGADS! Scary everytime I think back on it.

Between 50 and 60 mph on a ten speed down a very steep mountain road. My friend had a speedometer on his bike. The speed limit is 45 mph there and we passed cars. We were aboyt 15 yrs old.
It was scary as hell-I prayed not to hit any gravel. The road rash would have been horrible.
I hope my kids never do the same.

Probably over 30mph on my bike down hill in PA.

I biked down Mt Haleakalea, I think the rule was you were supposed to stay below 25 mph.

25 mph on a bike on a road in Florida(not downhill), with the wind at my back(all of you bikers know why I'd mention the wind. Ugh).

I biked down Mt Haleakalea, I think the rule was you were supposed to stay below 25 mph.

I did too! The top of Haleakalea looks like the moon-and early in the morning, its about the same temperature.

We kept a leisurely pace though-I dont think we broke 20 or so.

I pegged out the speedo on my bicycle on a 15 mile incline coming down the mountain in Lander Wyoming. The posted speed limit was 35mph and I had to pass the cars in front of me or plow into them.

The look on their faces was priceless...

OTOH, I had also hit a pucker-factor of 30,000 Fass units, 'cause if i so much as hit a single rock or touched my brakes I was going to die. :eek:


edit: CL - looks like we had similiar unfortunate childhoods... :p

Sky diving...i weigh 11 stone, work it out:P

About 50mph on a racing bike down a really steep hill, but gravity did most of the work.

I'll say I was fortunate in this instance as I made it in one piece. I know what you mean about touching the breaks-or hitting a small deposit of silty gravel or litter-it would have been a really painful mess.

Once I went down a much less severe hill on my skateboard and wiped out- landing on my hands and knees. I had flaps of sking hanging, with gravel and dirt embedded in the wounds. And that might have been 15 miles per hour.

About 80 km/h, before I fell and broke my arm on 6 places, bruised everything and had a lot of wounds. :D

It was on a rocky moutain trail in the Ardennes. I was busy getting all the little stones out for about an hour.:(

i think driving on a "mofa" (a small bike with a motor , which normally drives 25km/h) and was be pushed by my friend on a motorcycle... downhill...it was 112 km/h...

And I have had no brakes :eek: :eek:

Same as a car going downhill then? ;)
As long as it needs muscle power to accelerate on a flat surface, it's human powered.

Sky diving...i weigh 11 stone, work it out:P

As Galilei proved in Pisa, your mass does not matter the least.
Anyway, that should equal to 200km/h. AFAIK, that is the absolute maximum speed of a person in free fall. So, you win! ;)

Mofa - moped.
Three years of German, and that is all I learned.

Lovely stories, all. I was wobbling immensely when I set my record, but felt quite confident anyway. I wonder how a moped would handle at 112km/h...

Same speed, rode toward one of those radar devices that the police leave chained to trees on rural roads to point out to drivers how fast they're actually going. I've heard those things have a camera on them to catch speeders, but I've never gotten a ticket from one.

With stop lights and whatnot, I used to make it to work in half an hour traveling just under 15 miles. I'd say I commonly got above 40 miles an hour without a hill.

a kreidler flory i have driven rides 100km/h....it goes easily..the difficulty was that my friend pushed me..i have had not much control

475 mph on a Luck Dragon.

btw : the difference was in the year 1977:

a mofa drives 25km/h no licence needed
a moped 40km/h you need a driving license

About 50 km/h, down an extremely steep hill on my bike.

Oh, I've gone over 36 mph on my roadie, down this short but steep saddle in the road at my college. I top out a sprint at something like 33, I think.

I hit 41 mph when I was like ten. I was poor, and biking was the funnest thing to do, but i was poor, so I didn't have any brakes. When you're a skinny little poor boy (less wind resistance) without any brakes, a 41 ain't too hard.

And you're right. I mixed the two up, and don't know why I did it. =/

Hell, did you just fluffle yourself??
This has got to stop. Take this instead: :fluffle:


As for the OP:
Dunno. Has to have been either on a bike or on skis. Seeing how I'm an abysmal skier, I'd say bike.

Ahahaha. :p

OK you must remember I am a former professional bicycles racer. I was also extremely stupid to do this and do not recomend it to any one ever!!!!!!!

I used to have to commute at night through farm and ranch county in North Texas. One night I was passed by a fully loaded gravel truck but caught up to him at an a four way stop about 200 yards farther on where farm road 720 crossed US 380 (This is now a suburban area but then it was very rural) Because the roads were generally deserted I didn't use any kind of lights because they just attracted dogs, plus this was before the days of good battery lights and the generators tended to tear up my expensive tubular tires. I grabbed hold of the locking chains on the back of the trailer and put the other hand on the tops of the bars. I let him tow me from just North of the town of Little Elm all the way into Denton. My old (Pre cyclo-computer) mechcanical speedometer showed as high 85 mph.

If there had been anything in the road or a bit of uneven pavement I would have be a human crayon. But, man was it a ride.

There is a long hill on that ride that used to have really narrow bridges at the bottom I could sprint down this hill in the daylight and pull out into traffic and cross the first bridge. So that was at least 60 mph without the help of a rock-truck

There is also a 100 mile ride in the Houston area every spring called the "Katy Flatland 100" The highest point on the ride is a bridge above I-10. When you are coming back to Houston after the 1/2 way point you have about about a 25 mph tail wind. It is easy to hit speed of 40 to 45 mph and hold them. People in cars slow down and say "Do you know you're going 45?" I'd answer "Is that all? I thought I'd be faster"

I went down a black ski run at some insane speed i have no clue how fast it was but i did break one skii's binding and snapped one in half and fractured my kneecap when i hit the rock i didn't see.

around 35 mph on a bike down a super steep hill! :p

On a sled being pulled by a car. Not exactly human powered, but still an interesting experience.

About 6 mph in my Flintstones toy car thing...that was badass, and it was the flagship of my mighty gang "The Boll Weevils".

61KPH down hill on my bike, wobbly as Hell.

Does is count if i had a team of human slaves doing the work?

Downhill skiing if that counts. No clue on the speed.

30-40mph going downhill on a bike.. can't be more specific than that. Was bloody ages ago.

Probably 30-32mph on flat ground for a bike.

But those involve science and/or gravity. Couldn't pure human power be considered just walking/running/swimming/climbing?

OR! If we count it, I'm sure falling off of something. I'll bet I went very, very fast before I went *THUMP!*

73 kph downhill (obviously) on my old mountainbike. I had a speedo, hence I know the exact speed. There was a sweet little hill near the gym that was just perfect for getting up to high speeds. Speed limit was 50 as well. Once got flashed by the speed camera, which was cool.

No idea, I have no speedometer on my bike. The only thing that comes to mind was a particular stretch downhill on my way to work in Munich. I was fast enough to overtake cars.

done 48 mph on my bike (~ 77 kph), and get over 40 quite regularly, but till not pushed it over 50 mph though - the hill's just aren't good enough round here. There is one road though, coming from the Mendip's (UK) back into Bristol where a friend got up to 52 mph. Guess I'll have to give that one a go.

On skies: some 90 km/h-ish and on my MTB I've done something around 65-70 km/h down a skiing slope... yup, I had a speedometer but those aren't 100% accurate:)

45 MPH downhill, over took a police car and almost got knocked off mountain bike. Luckily cop car was stuck in traffic cus its onlya 30 zone

A few of you have broken the speed limit on your bikes/rollerblades/mofas. I wonder if speed restrictions apply to non-motorised vehicles.

Demented hamsters, you should've gone by the camera with a sign at the front of your bike with your name and address.. ;)

I've got got by a speed-camera on my bike, too :) Not hard, really; down Rockingham Hill you'd have to break to not get caught. The corner at the bottom's a nightmare at >30mph, though...

I never managed to set off the camera on the A4 in Roehampton (South London), but I could keep up with the traffic down the hill. It's a 40mph limit.

I once crashed my friend's bike at about 30mph (it has a speedometer) into the back of a Merc. Bugger wasn't indicating. Didn't damage the bike much, fortunately, and I rode home.

It is a vehicle, hence the rules still apply, you have to stop with your bicycle at a stop-sign as you do with a car as an example...

A bit ironic as a bike doesn't have to have a speedometer..

Probably on skis down a hill. Dunno how fast it went, but it felt like approximately one hundred billion miles per hour.

on a road bike ive got 58kph on the flat and about 84kph on a downhill but it isnt that steep here

67 mph on a road bike in vermont. I couldn't stop in time at a intersection and got a $250 speeding ticket from a vermont state trooper.

21 mph, downhill. Mountainbiking.

I helped my uncle procede to break 80mph (~130kph) on a snowboard, by pulling with a snowmobile, not entirely human powered but he did release the rope at 80 and finished the run without power,

i'm a little bit of a wuss, but my friend drafts off of semis on the highway with his road bike, usually going around 60mph or so.

when we're riding down the canyon we pass cars... kinda funny.

Do sail planes count, as they are powered by gravity (weight of plane and pilot)? If so, then 95 mph (153 kph) is the fastest I've gone.

When I was like.. 8. Me and my cuz decided to go down a hill in a red wagon.. crashed into a pine tree.

When I was 12, my bro, a friend, and me decided we should go down a hill on bikes fast. They stopped, I didnt. Ouch.

Dunno the speeds tho.

47 MPH on a racing bicycle down a mountain road in the French Alps last year.

The fastest i have ever traveled on wheels is 24 mph on a 21 gear bike.:fluffle:

Not exactly sure how fast it was, all I know is that the speedo ended at 155, and the needle was past that, and we were still accelerating...Just saw it said human powered....I have no clue.

55 mph (Honda Odyssey). I'm a beginner driver. Once I have been on the road for a few more years... Who knows what'll happen....

Since this is just "human-powered", I'm going to go with what some others have said and not count hills.

34.7mph at the end of a race during a sprint on a bike. I beat the other guy. :)

Well, i don't know... I can go pretty fast down hill by bike, once went pretty fast going up hill too though (fast for going up hill), but then i fell into the bushes at the side of the road... *hmm...maybe that had something to do with the fact that i was sorta drunk* but for going up hill it was still pretty fast.

Do sail planes count, as they are powered by gravity (weight of plane and pilot)?

Only if you took off by flapping your elevator and rudder. Did you do that?

Not a clue... Probably about 50 mph/80 kph on skis.

Much more satisfying when sailing though... Even doing like 20 knots or so, pull a tight roll tack and gybe back again, real fun.

Some 60km/h with a normal bicycle going downhill. (Could be very inaccurate, the bicycle counters (or whatever they're really called ._.) aren't that good...) But fast enough.

20mph on a mountain bike, racing along the road back to my house when I was 12.

ive done 110 km/h on a skeleton. THAT was scary!

Same here. There was this huge hill on my way to college, I used to free wheel it all the way down every morning - 2 miles in 5 minutes! That was so damn cool! Kinda freaky though when you pass out cars then hit that huge pot hole some prick left behind the night before just so he could get home to some good lovin'. The speed limit was 30 there, so I know I did at least 30, probably a little more considering I overtook cars...

Yeah, there's this HUGE hill by my house and I did overtake a car once. It was EXTREMELY fun!;)

I passed a car in my wheelchair. The speed limit was 25, and the hill was rather steep. So I can safely assume I hit 30 mph at one point. Going down was fun, it was the stopping and going back up it after 4 hours at a bar that really stunk.

30mph on my bike downhill, good fun.

50 mph on my bicycle. scariest ride i think i'll ever take on my bike. unless i exceed my goal of 60 mph. which i will probably die trying to do. :-p

I hit 47 mph on my Trek 1500, downhill. Thats about 77 kph. It feels so much faster on a bike.

Bike Touring, I’ve been up to 55-65km per hour (according to an accurate bike computer) a few times for periods of up to 20 minutes on really long descents in the Canadian Rockies. I could go faster but I tend to use the long down hills to rest and sometimes eat a snack, so I sit up straight most of the time on the really long descents. The only thing that really bothers me is that when I hit 55 the air friction is fierce enough to push my helmet mirror back against the helmet and suddenly I can’t see if there’s any big rigs on the road behind me. Handlebar mirrors vibrate too much at that speed to be of much use.

On sprints on the flats I've gotten up to 48kmph for short bursts on my mountain bike and sustained speeds of over 30-40kmph for an hour on a fully loaded mountain bike (of course I was being chased by a thirty foot long column of black flies drafting behind me for inspiration). I didn't even go below 30 going up small hills, I was so worried about being overtaken and eaten alive.

My new bike, Brodie dynamo, is faster than my old bike (Kona Hannahaha) so I'm expecting to go a lot faster on the open road this summer.

The Bruce

About 43-44kmh, on a mountain bike, on a level grade, using my legs for power.

104 km/h on skis!! :eek: BURN BABY BURN was the only thought going through my head!! But since skis probably dont count, I've been about 40mph (39.7 to be exact) on a trail up in New York.

140 mph or Mach 1.2, depending on how you define "driven".

About 30-35 km/h on a bike. Not certain when it comes to alpine speeds, but somewhere between 30-40 km/h there as well.

(Morfinniel: 140 mph or Mach 1.2, depending on how you define "driven".)
As in powered by human muscle, and a 140 mph isn't the speed of sound. It's more like 600-800 mp/h unless the air is really thin, as in above 50.000ft.

i am an extremely fast runner with powerful legs so i can get a good speed

i have done 56 KPH (35mPH) on a very short run down a small hill.

I have seen a video of a guy doing 160KPH on a bicycle down a mountain and then crashing quite bad, amazing speeds though!!

about two years ago my buddy and i bought a radar gun and we were seeing who could go fastest on a skate board on a super steep hill and i pulled 37 mph by the bottom of the hill it was the scariest thing ever...........................................:confused: it wobbled alot

About 70kph on a mountain bike

312 km on a gpz 1100 obviously used a helmet but not incase i fell off the bike but to stop the wind from pulling out my eyes..!

I've gone at c :D

80kph on a Mountain Bike

And for shits and giggles, 300kmph in a V8 Supercar

Well I have gone over 90kph on skis...

As for non human powered, 140 mph+ in a Merc E240

41 mph on a bycicle on a shallowly dowhill road.

I once bungee-jumped whilst on a bicycle- does that count? lol

I know I've done 29 MPH on a flat GS race course, but I've probably gone much faster on my skies. I've also gone probably around 30 MPH on my bike down a very steep, short hill. I then tried to do it on roller blades, hit a pebble, but I was luckily able to stay on my feet.

Some time ago, 40 km/h on a bicycle *not downhill* :D
Some other time when it actually was downhill, I got 75 km/h :D

Right now i'm doing 1000 mph or 67000 mph, depending on the point of view. Not breaking a sweat either.

well does a glider count, its not powered by an engine, if so that about uh 100 maybe

if that doesnt count then probably about 30 on a bike

and so many of you guys are clearly lying

~50 km/h on rollerblades! Hanged on to a driving car for about 100 meters. Scariest ride EVER!

"Skitching" is where one crouches at the back of a car, grabs hold of the bumper, and is pulled along by the car when it travels over a snow-covered road.

It's extremely dangerous. It's also lots of fun. We got my uncle to go about 30 mph (50 kmh) when we did it when I was a kid.

Around 70kph, skitching on the side of a car. I equalled that on rollerblades, a bike, and skis, though only the skiis were derived completely from non-motor sources.

"Skitching" is where one crouches at the back of a car, grabs hold of the bumper, and is pulled along by the car when it travels over a snow-covered road.




You don't have to only grab hold of the bumper. You can grab hold on the side of the car, especially easy if they roll down the window. They would have to know you were on the car, which in most skitching cases the people don't know.

The ultimate was to get on to the back of a plow but that was doubly dangerous since it was possible they would start sanding the road which would equate to a facefull of sand.

I hit 30 MPH regularly on flat ground, that's on my commuter bike, a cyclocross bike with road tires, rack and a barbag.

They have these electronic signs they put out in residential neighborhoods that show your speed, supposed to slow people down, let them know they're speeding.
I discovered that they pick me up on my bike.

So now whenever I see them I sprint to see how high a reading I can get.

Tops so far is 32 MPH.

I'm buying a new road bike this season, It'll be at least 10 pounds lighter than my commuter with empty bags. I can't wait.:D

close to 50mph on a road bike durring a race. That was the scariest moment of my life :D

75.3 kph / 46.8 mph downhill on my road bike, measured with a speedometer that records maximum speed. I'm now convinced that anything over 55 kph/35 mph on a road bike is pretty much insane, at least for me. If I hit a rock, I'm toast. My ability to steer to avoid said rock is pretty much gone at that point also.

45 mph on a mountain bike down hill with mud flying off my tyres and the tyres of the bike in front of me. we actually passed a yellow mustang!

I think I hit 30-35 mph downhill on a bike WITH NO GEARS:eek: . I would've went faster but at the bottom at the hill it was a cul-de-sac so then I ended making a 50 ft long skid mark before getting catapulted by the curb... luckily I landed in someones yard instead of someones driveway.:p

we took our 97 cobra and tied me to the top 2 times and we was going about 95 mph, it was fun as hell, but I will never do it again...too many bugs...

the seccond time it was a 64 mustang (red) and we was going over 100 miles this time, down a hill, I shit myself that time...


oh yeah that and when we stoped and I got untied I kinda felldown and puked for a minit or so... suggestion: dont do it...

was damn fun though... scarry, but fun... like the invasion of normandybeach... of operation overlord in WW2... I see dead people

and satan posesses my phone...:eek: :eek: :eek: :eek:

yes. I am compleatly crazy...

My computer on my bike said 85 but I was passing cars like crazy. I was cycling through the Rockies (Jasper to Banff) and after climbing one of the mountain passes I got to enjoy the benifits of my labour.

That was 85 kph from my last post

I'm embarassed to know this, but, not true. Warp drive does not actually make the ship travel faster than light -- it creates a bubble around the ship in which distance beteen two points is significantly shortened.

Now, full impulse on the other hand...

Amusingly, I can indeed tell you why he is correct. Quickly it's because space can be manipulated and deformed (it's actual 'shape' and i can give an example ;) thus you should be able to condense the space between you and your destination meaning you travel that distance without going as far which means you aren't going fast! ;)

Ok well on my bike I think I've done about 30 mph. My friend was going pretty fast down this one hill, until he managed to hit the one and only bush on the side of the hill, causing him to slam his nads. HILARIOUS.
Snowboarding I've gone down a small midwestern slope of less than a mile fast enough to make the snot fly and the ears pop...

Same speed, rode toward one of those radar devices that the police leave chained to trees on rural roads to point out to drivers how fast they're actually going. I've heard those things have a camera on them to catch speeders, but I've never gotten a ticket from one.

Wow, I forgot to mention my experiece with police speedometer things... I full out sprinted as fast as i could on flat ground and broke 10mph, on my BMX bike (1 gear with a 39-16 ratio) on the same flat gound challenged 20mph. I could done notably faster if i had gears. So i believe the whole flat ground thing makes mine very much 'man power only'

On my bike (now stolen, but it was falling apart) lots of time very very fast. Even when it was falling apart, it still went fast... chain locked up sometimes while pedaling.... and I WASN'T WEARING A HELMET. Yeah, I haven't gotten around to getting a new one......

If I consider myself a human-powered vehicle, then about 9.8 m/s minus whatever drag my body created. Although technically I was more of a gravity powered projectile, hurtling towards the ground after jumping out of that perfectly good airplane.

25 mph on my bike. IN my car, faster than I care to admit.

about 15-20kmph on a 'blade' scooter- can't seem to beat anyone, lol.:headbang: :headbang: :gundge:

Why do people keep posting downhill speed?

Doesn't anyone know the difference between gravity and human powered?

I didnt personaly do this, and it may sound absurd, but, i gotta tell you couse I think it be funny,

I had built a fairly large catipult for the pumpikin chunkin I was gonna enter, and my freind broke it by using it to propel himself into a tree in the cematery like200 feet away and he kinda broke like .... EVERYTHING
includeing the catipult it wasnt desinged to shoot a 154 pound man but a 50 pound pumkin, and we had done test shots, that whent prety damn far, so, he kinda screwed me over on that one...

dont know how fast he was goin but he was goin fast...like 56 feet per second or sumthin, I think he should have died, but he didnt...

then I woke up

there is somthing hiddin in this post see if you can find it. if you do you get a prize...

7200 RPM in 6th gear in my 2004 Subaru WRX STi

equates to about 172mph :D

Hey, my right foot powered the car.:p

On a flat surface about 55 km on a mountain bike. About 70kmph downhill

49.5 kph on a long stretch of road, 18th gear pedaling like crazy... was fun.. did it several times after that again.

I have gone 55 mph on a mountain bike. I had a computer on the bike, and my friend driving behind me. It was a 13 % grade, so that helped a bit. Funnest thing in my life. Wheels were shaking and everything. I am bomb time bomb.

I think any skydivers get the winners purse on this one. Hell, they're certainly being human powered (by their own mass being attracted to the mass of the earth by gravity) and they accelerate at 9.8 m/s/s. Hell, after ten seconds they're going 98 m/s, and they only get faster after that.

Till you hit terminal velocity.

Till you hit terminal velocity.

Or hit the ground :cool:

"then I woke up"

The fastest I've ever driven was 105 mph in a 1998 Saturn SL2. The fastest I was skiing was about 25 mph downhill when my ski snapped off... Yea, I hit the ground hard in a basic explosion of snow.

60 mph on a road bike, downhill. I was in a race and was trying to win

EDIT - oh, human powered. D'oh.

I've been 25mph in my wheelchair on flat ground. 40 on a hill. :)

... can't say how though. ;)

i wrode 27 miles on a ****** one time. he didnt go very fast because he had shakels on but i whipped him for 6 straight days in order to complete this impressive feat.

that one made me laph... XD :headbang:

The laws of physics are lost upon those that post.

ummmm this website is fun and the devil shall rain blood on your pathetic souls:upyours:

60km/h on good, straight road with not much wind on a bike. I've probably gone ~70km/h downhill on a bike in Italy, but had no way (or will) to measure speed back then

ummmm this website is fun and the devil shall rain blood on your pathetic souls:upyours:


someone seems to have a few minor problems..:sniper: hehe jk

i drove a car at 75mph,once,when i was 12..

I hereby declare myself fastest self-powered human on NS...

Anyone care to claim different, step up and prove it.

I'm ready (http://pictures.sprintpcs.com/mmps/RECIPIENT/000_064697092319535_1/2.jpg?partExt=.jpg&limitsize=280&&outquality=90&ext=.jpg&border=2,255,255,255,1,0,0,0,0) and waiting...

~50 km/h on rollerblades! Hanged on to a driving car for about 100 meters. Scariest ride EVER!

Then it wouldn't be human powered anymore. :S

Hmmm...

If I remember correctly, I hit 80 kilometres an hour going down a hill on my road bike in Cape Breton Island. That's about as fast as I'd like to go. Crashes get nasty at speeds like that. I have crashed at ~55 kph in the past, though. Escaped with minor road rash, relatively unharmed.

Edit: Without gravity helping me out, I hit ~65 kph on my bike on a flat stretch of road in Southern Ontario.

Not if you can calculate and present to us your average velocity.

Well, when you're falling down a mountain, as you know, it's the force of gravity that's pulling you closer and closer towards the earth. The acceleration of gravity is 9.81 meters per second squared, so... well, actually, I don't know how one would convert that into a system of speed we can understand, but... that's what I remember learning in physics.

Incidentally, the fastest I ever drove in a car was 80 miles per hour. I know that's nothing compared to you speed demons, but that's a heck of a lot of speed for me.

No idea, but my best guess is somewhere between 30-45 mph...don't know the metric :(
