    From a well respected online bike speed calculator. Based on my height, on a flat road, no wind, for 1 mile, I'd have to push 1500 watts to hit 40 mph. This would take me 1min 48 secs to cover that mile.

    Mark Cavendish peak power is 1600 watts, and he sprints about 1000 watts for about 30 secs.

    So again, showing that cyclists do not hit these speeds on normal roads unless they are super human or the road has a steep down gradient and even then it's only the fastest few who hit these speeds.

      Electric bike are limited to 25kph/15.5mph at which point the electric assistance cuts out, so I'm sorry fella but your claim that electric bikes have been clocked at pver 25mph is nothing to do with them being electric bikes. Scooters equally have limiters so unless someone dcotors the setup, then then equally won't be going at 25mph.

      I just love the rubbish that people who don't cycle claim about cyclists
      25mph> the 20mph speed limit I just love the rubbish the hard of thinking talk.

      If you exceed the speed limit you break the law your invented speed limit of 40mph has no relevance and as usual you don't have anything sensible to say.

      Lawful electric bikes & scooters are speed limited but very few are.
      Always forgive your enemies; nothing annoys them so much.

        It’s clear you don’t know where you’re talking about.
        1. It’s steep
        2. It is sunken lanes, so no guarantee of the quality
        3. Look at the pro route on the only prudential ride 100 and find the most difficult hill.

          Erm, yes, I'm fully aware of that.

          Read the thread. WTFH quoted cyclists going at 40 mph. I was responding to him. You do realise that there are more posters on here than you?

          As for your 'speed limit' quote .... this doesn't apply to cyclists. We can't be done speeding. Bikes don't have a speedo. We can be done for a very old law which is something like ... "cycling uncontrollably" .... I'm sure someone will find the exact trem, I can't be bothered.

          Really? Care to like to the evidence of that or is this your usual guff when when lose an argument?

          Given electric bikes can be £1000+, some well over £5k, I'd be very, very surprised if anyone messed with them and made them illegal.

          Can't answer directly for scooters, but given only hire scooters are legal, and these represent 95%+ (my made up number, it's likely higher than that) of scooters in use, I'm pretty sure you're talking absolute crap.

            1. Erm .... did I not say unless it's over 4-5% gradient? I quoted you a local road like that, and only a top few hit anywhere near those speeds.

            2. If cyclists ride those roads frequently they learn every single pot hole, man hole cover ... trust me, it's know these roads that keep us alive and why we sometimes ride in the middle of the lane despite dick drivers thinking we should always be in the gutter

            3. I did ask you to quote the road. You haven't. But please feel free to do so and I'll happily look on Strava and can verify your claim that you often drive behind cyclists doing 40mph down t here. If you give me an actual day this happened, and assuming the cyclist is on Strava (most are, as we're obsessed by our times) then I can tell you who the cyclist was too.

            Love you anti cyclists. Haven't got a clue what it takes to cycle fast and safe.

            Next ....

              It’s not just pot holes and manhole covers, but hey, ignore the facts that you don’t know those roads. They are sunken lanes. The earth banks on either side have trees growing on them to hold the earth in place. Those tress shed leaves and lose branches all the time. The banks will push spoil and stones onto the roads. You can go down one of the roads one day, and after overnight rain, the debris can make a big difference.
              Oh, and then there’s the wildlife, e.g. deer crossing the road.
              And horse riders.

              But hey-ho, ignore that. Ride in the “middle of the lane” and you’ll hit a cyclist coming UP the hill, cause you’ll be in their path.

              But since you ask, run your strava on this as a descent https://veloviewer.com/segment/96609...bour+lane+full
              (It claims a max grad of 14.7%, other cyclists say it hits 20%)

              Here’s a cyclists view going up the road - remember, this is an open road with traffic flowing in both directions.

                Here’s a descent, look at the rider’s position - overtaking on outside of bends, coming to blind crests, etc. This video is from about 5 years ago, as the oil protesters were still camped out.

                  OK. What you "fast and safe" cyclists regularly fail to realise is that you are still travelling at on average less than a third the speed of the surrounding traffic, and that your desire to shave a few seconds off an already pointless activity does not justify forcing everyone else to wait behind you for a while until it is safe to get past you without putting you in (even more) danger - which includes you getting off the damn road when a suitable space appears (which it will).

                  Or, as happened just yesterday, being in line of at least twenty vehicles behind on guy riding up long, steep A-road climb out of Wells at a lot less that 40 mph, ignoring all of several chances to let people past safely. Two miles in 10 minutes.... And you wonder why drivers get irritated.

                  The needs of the many are supposed to outweigh the wants of the few. Cyclists never seem to have heard of that particular aphorism.

                    Are you saying all cyclists are Tories?

                      You really need to learn what Conservatism actually is rather than believing it's what the Guardian thinks it is.

                      Had you said "Socialists", you would have been more accurate.

                      Meanwhile, stop lecturing me on politics; I'm not interested.
