What's the fastest speed you've reached on a mountain bike?
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.Posted 5 years agothe wandererMember
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.Posted 5 years agoRusty SpannerSubscriber
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… 🙂Posted 5 years agomessiahMember
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.Posted 5 years agoportlyoneSubscriber

GPS max speeds are pretty unreliable anyway, aren’t they?
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.Posted 5 years agoloweySubscriber
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.Posted 5 years agosuperfliMember
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.Posted 5 years ago
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
