I did 31.1 mph the other week which is the first time I used my Garmin for speed. My mate has done 41 mph but I think that was on his road bike.

About 45 down a very steep road on the mountain bike. Fastest on a road bike was 53, but that was converted from a computer showing 85 kph dunno how accurate they are tbh

49.5 on the quantocks one summer. 55 on a road bike into Shepton Mallet.

I've not measured speed for years though.

Over 40 on a straight fast section at La Molina bike park. (my mate passed me doing 43 or something)

36mph on the final descent at Relentless 24 according to my gps. Wouldn't like to go a whole lot faster off road to be honest.

47.5mph, with 2" Schwalbe Marathon XR tyres, carring 40kg of loaded panniers, down the Lidis Pass in NZ. I'd met someone a week before who'd managed 50mph on the same road but I just couldn't (relatively safely) manage it.

Edit: According to my old computer, I'd regularly achieve around 180kph every time I crossed the border into County Durham from Northumberland.

327km/h is the fastest I have readily available evidence for, although I have clocked in excess of mach 1 uphill before.

OK in reality, just over 60km/h on the descent to Champery.

~75kph on a MTB in the Quantocks (like Scienceofficer)

~80kph on a road bike coming down from Buttertubs Pass - I whimped out at the thought of hitting one of those stone walls

43 down Drum Mountain. My poor brakes were absolutely cooked at the bottom, and I had oil pissing down my fork legs

82kph - Around 50 mph on the "red hot rim run" back in the day before discs! It's an 8km long fireroad north of Melbourne. Can't believe I would do that on a rigid xc bike wearing shorts and t-shirt.

In a great display of physics if you hit a rock (and there were many) the bike would have so much inertia it would just pop back into shape.

Usually going my fastest just after leaving the bike, but got no speedo on my body to tell speed. I'm sure there is a scientific formula based on bruise size and body weight to calculate speed of impact though 😳

Managed 60kph on the bit down from the top of the Marmottes lift near Morzine. Probably managed more on the roads down from the goat village, trying to get away from the smell...

Off road, 41 and a bit across the fields after you cross the road on the drop down from Embsay Moor to Bolton Abbey.

This seems to be the average speed that most people hit without really trying going by previous threads on here.

I reckon I could beat it on the drop down from Drum to Llanfairfechan, but I'm too scared these days and it's not worth missing the view. 😀

EDIT - just noticed Binners post - great minds & all that... 🙂

Goat village road was too busy. Stuck behind cars, and couldn't pass them on inside of the bends.

Too right about the stink though.

Road to champery is less bendy.

GPS max speeds are pretty unreliable anyway, aren't they? If it loses a point or two then snaps back, that could surely produce a duff reading?

71kph (44mph) downhill in the slipstream of a wagon. I could feel myself getting pulled along in it's wake. Completely sh*t-scary and brilliant at the same time. Never managed more than 55kph on the same stretch of road since

1991 when I last had a computer on my bike I used to clock 41 on a local offroad hill and 43 on a road hill... on my Rocky Mountain Blizzard with rigid forks.

I tried fitting a 52 tooth chainring to see if I could go any faster but it didn't work.

I've not had a computer or GPS since as I really don't care how far or fast I'm going.

Very.
And Endomondo/Strava/Mapmyride/Runkeeper filter and process the data even more than the Garmin/Magellan/etc. and make it even more unreliable (but usually probably lower on a "good" track).

My 60+ km/h recorded on VDO speedo is reported at about 40km/h on endomondo.

That 327km/h reported on Runkeeper appears absolutely normal on Endomondo, despite it being the exact same GPX file.

About 45mph down a closed road in Morocco on my MTB & about 55mph on my road bike in the Alps.

Not sure I could go much faster on either...

i once hit 63mph on a MTB on a road in Newcastle when i was 16. Looking back, I probably hadn't set it up correctly 🙂

Hit 54 on a road bike before, not sure I'd want to repeat that sort of speed.

45mph on a road (on a mountainbike)

Not really something I'd measure, the faster your going the easier the track probably is.

Comes up regularly this thread.

Again, descending Drum Mountain into Llanfairfechan with Junkyard and Justme from here... Junkyard's GPS showed 49mph and I went past him so thinking just over 50mph.

Its very wide and grassy so you cant really get a full idea of just how fast you are going until you hit the brakes. I admit to being a little scared when I pulled the lever.

I gave a friend my GPS to stick in her pocket on the Fantasticable - recorded a nice smooth acceleration to just short of 100kph and back.

50mph at dusk on Tioga mud tyres on a damp road, dropping from the end of the South Downs way into Eastbourne, it's flinkin steep and I was braking 'so' gently to avoid what I knew would be horrible death.

Off road, 40ish..

Offroad, 43mph in Richmond Park

(both via speedo)

49.5mph in mid 90's down Butser Hill according to my bike computer. That still stands for me. Minimal front suspension, but big chainring and bigger balls.
Same hill last year I got 44.5mph measured on phone, bike comp and Garmin, so I know that is accurate. Its on Strava too. http://app.strava.com/segments/2388865

A mate clocked 55mph on a fireoad in the Alps (dh bikes) (computer, we checked the setup afterwards too) I had gone past him at the point a bit faster as well (full aero tuck), so who knows 😯 😕

Bit dissapointed if I don't hit at least 30mph when I go out on the MTB

40 mph off the top from Gillamoor down the road. Quite exciting when the bike is set up soft for off-road.

48mph on a flat bar Boardman down Round Ings, and 47 down Ripponden Bank on a MTB. Off road, just a whisker over 38 down the old fire road finale at 'Degla.

probably hit the fastest speeds on freeride bike that doesn't have a speedo, but I'd estimate 40 tops.
Done 50+ on a road bike a couple of times but not for a number of years - my road bike is looking a bit tired and I'm a bit nervous of the forks snapping after I rear-ended a taxi last year! should probably replace them.
scariest speed though is on the fixed road bike down potholed hills with cars about, doing 120rpm - probably only 26-28mph but feels like waaaay more.

49.8mph on my Anthem X, down a firetrack descent in France (I was determined to break 50mph) Surprisingly, the bike felt absolutley fine at that speed - only 'slight' problem was scrubbing off enough speed for the 90deg corner at the bottom of the hill 😯

The bike did 80mph once.
But I was a few feet in front, inside the car.

39.6 mph on the MTB down the hill in Grizedale. Had 3 attempts but still couldn't hit 40.

44 and still accelerating on road on the CX before hitting the brakes. Chickened out bacause the road surface was rubbish.

58mph coming down the back of corney fell somewhere on mtbs in 1995/6. A group of about 6 of us all had speedos showing roughly the same. I slowed down when I started to wonder what would happen if I just slammed my front brake on.

A couple of days later we tried again but in the wet - 2 people ended up in hospital.

Off road, 41 and a bit across the fields after you cross the road on the drop down from Embsay Moor to Bolton Abbey.

Is that just before Westy Bank Wood, or on the BW that goes due south and hits the lane some way outside Bolton Abbey. I can see how you might be going a bit on the latter, but I can't conceive how you'd manage it on the first one!

It was on the two fields just before the wood with the nice bit of singletrack in it.
Edit - yep, Westy Bank Wood.

Ms S held the gate between the two lower fields open. 🙂

I'd stopped for a pee a bit further back and was trying to catch up.
Was very smooth and dry, you can get a hell of a run up too. 😀
Biggest problem was avoiding the sheep.

49mph downhill on a roadbike.

40mph on hardtail down a fire road, think that had a 44t ring

38mph on 7" travel bike on road, 36t ring, kinda span out the gears couldn't peddle fast enough 🙂

44.5mph on Rollapaluza but i was half pissed and sunstroked and never done it before 🙂

Don't worry about speedos to much anymore either, i know if i am close to 30ish as my eyes water up 🙂

My maximum according to Strava was a mighty 19mph in similar conditions...<sobs>

I remember I was pedalling flat out in the big ring, so I still don't know how you managed it...

I have a natural advantage for quick acceleration on the downs 😀

I might have hit the top speed dropping down off the moor on the Bridleway, but the corners are a bit sketchy and the flat out sheep chasing bit certainly felt the fastest.

Gunnerside Gill, the drop down from Llyn Anafon and on the road (on the MTB) down the Horseshoe Pass from the Ponderosa are other favourites.

Just can't seem to break 42mph on the MTB no matter how hard I try.
Might be aerodynamics 🙂

55.7mph on a Lap 714 on a road into the back of halifax via Southowram bank, felt like legs where doing 110mph and forgot there was a slight kink in the road halfway down, so straight lined it, nearly had head on with car and forgot there was lots of moss on the road from stagnant water too.... had minor orgasm at the bottom and heart attack climbing back up it 8)

i used to own a traffic sign company, we had just fitted a new vms sign which shows the speed that road users are travelling at.
i decided to try it out by being towed uphill on a demo 8 by one of my staff in his fiesta.
clocked a reasonable 62mph.

According to the speedo on my old bike, 39.9 mph (gutted I was).

Full sus MTB down Churwell Hill, Morley (road) if anyone knows it.

Off road? Who knows? Maybe 10?

update to earlier posts (can't edit them):

65.8km/h was the highest I recorded on speedo down to Champery (so just over 40mph). Probably maxed out at 40-50km/h on descent from goat village.

51.5 mph according to my Cateye Mity- back in 1996 on my Marin Bear Valley.
I was having it down Castle Hill near Eynesford in Kent and i reached this dizzying speed as a 90 degree bend appeared at the bottom with an elderly gent in a 'rusty gold' coloured Austin Maestro right on the apex.
I think he was more scared as i narrowly missed him 😆

I'm an adult now, so i tend to take it a bit easier these days....

Edit: I'm pretty sure i went faster than this down some gert big hill in the Alps several times (in 2004). Although i didn't have a cycle computer so who knows!

Edit (again): Offroad? 1996 again on the same bike i went 44.6MPH on some footpath (officer) in the same area in Kent.... (luckily no ramblers were harmed during the making of that record 😉 )

lol @ choosing winter. suspect the water level was a bit higher than normal too?
rofl @ owning up to wearing a shellsuit.

My highest speed on a road bike was probably about 50mph going down Bluebell Hill. Need head tested to go down there these days I think.

50 odd mph down a mountain in Scotland.
On a rigid hire bike.
Wearing shorts and T shirt. 😀
(I was young)

Road bike I only ever managed just over 40mph; not many hills in my yard.
