So on a flat road, sprinting as hard as you can, how fast have you been? Personally have no idea but I'm interested.

About 30mph (road bike) - but then I'm fat, slow and honest.

I hit 52kph going down a tarmac hill towing my trailer on my inbred- rather irresponsibility overtaking cars.

Much fun.

fast enough to overtake a big tractor at full chat, in the days before compact drive chainsets, spinning my 48 ring, rumbling along on 2.1 smokes

Around 30 maybe a bit over on the tandem on 36 /11 top gear and 2.3 tyres. Absolutly flat out sprint

dunno, but have constantly tried to set off a speed camera on a slow decline (canonbury rd, highbury and islington)
never accomplished it to my disappointment,
has anyone ever set off a speed camera?

Can break the speed limit on road bike, cannot on MTB - well perhaps for a nano second.
Downhill.
48.2 mph off road though GPS to prove it we did not realise how fast we were going till we had to break for a wall and all shredded our brakes!!!
50 +on road - very scary

No - but I reckon it's more a problem of radar cross section than speed. Must get round to making myself a radar reflector (there's a camera on the flat after a downhill I reckon I can do 35mph past with the wind in the right direction).

There's one of those 30 signs I can consistently set off just down the road. Crucially the trigger speed is also a tad lower for those.

not the fastest (because this thread's been on before) but 72kph on a hardtail heading north on the Kjoler (Iceland) with full panniers and a howling gale behind. The bike was bouncing like **** and I felt like a trail god for 10 minutes (that is if trail gods ever feel like they've s**t themselves?)

I seem to remember getting and holding on my bike computer 31mph for about half a mile on a road bike. TBTH it was after a slight descent that got me over 30+ but my own power that kept me there. Down a hill on a road which I knew had no junctions I hit 63mph on my RB. I've also hit 55 on road on a rigid MTB coming off the Roches towards Leek.

This doesn't allow for inaccuracy of computer calibration but I feel certain error is no more than +\- 10% and I think closer to +\-5%.

41 mph on a run down to the chalet in the french alps, on a dh rig. I didn't believe it when I was shown and insisted on a re run the next day, It was correct. It was at the end of the week and the center strip of the tyre was bald as you like. Overtaking cars on some sections 😯

once coming out of cardiff in heavy traffic on a 4 lane wide section of raod that becomes 6 lanes we needed to turn right i was riding with the welsh road race champ and last years champ,we was single file and doing just over 40 mph i was just hanging on to the back,as we overtook many cars, looking at motorists faces as we went past them at over 40 on bikes on the flat was a real picture,i can still remember one lady looking up then at her speedo then back at me as we went past, o to be young and fit again

I did a 20.58 for a 10 mile TT, average over 30mph i think, and when I lived in Kent I went down Delting Hill at topped 68MPH.

Beat that ; )

49.8 mph down the otherside of Ditchling Beacon during the London to Brighton bike ride 2009
Un verified 56 mph down into Eastbourne, past the Eastbourne Downs Golf Club on the A259
Overtook a bloke on a moped once, the effort nearly killed me but the look on his face...

Rochey - Are you sure that 20.58 for a 10TT gives you an above 30mph average?

82kmh. Self Propelled off road.

Well, [i]I[/i] ate the pies and gravity acted on [i]my[/i] body so in essence, its all my own work......

50.4mph coming down the wiggly road from the kirkstone pass into ambleside, on knobblies in the wet. decided afterwards it was a bit silly given the circumstances.

Did a 10TT run by Reading Wheelers (?) a couple of years ago, starts at the top of a very big hill, I was doing 48mph after 27sec when the magnet on my Polar speedo slide down the spoke - had not reached terminal velocity by this stage so would have been doing well over 50, shame I only had a compact chainset on 🙁 23:12 for the 10 which is my best (so far)

The speed signs are easy to set off but gatso's are much harder. As above, I suspect we're not reflective enough, bit of tin foil across your back might do it. I keep meaning to give this a go on one near us which is on a nice long hill.

As far my fastest, this isn't it (I've seen 55mph, but this is the fastest I've got a picture of)
