So cool! I raced in 92 and 93 for Chico Sate. We were only one of three schools with full carbon monocoque frames and carbon Kevlar fairings. 180 psi front tire and a 67 tooth chainring. Brakes and shifters custom made by Paul Components. Such great me memories/unique experience.
I'm so happy to be alive at this moment. To be able to see Human ingenuity and craftsmanship develop these amazing machines, powered by the body. Inspiring.
Never knew this sport existed before this was displayed to my eyes - absolutely wonderful! Tried one of these during early-mid 1980s, and only a single of these in my town of 300.000 habitants, so thought it was pure retro class. But now with Garmin mount, dedicated race track, safety and other non-80ies things - heck, I'm moving to the UK!
Thanks for sharing this! I designed/built/rode an HPV on my college team in the 1990s. Such a beautiful sport--the combination of engineering, sport, and human ability is pure art!
Great race, congratulations! 😃 My, these things go FAST. Knew they existed but never saw an onboard. Must feel like flying, sitting in a cockpit-like capsule, that close to the ground, that fast! I could imagine ditching my road bike and doing some laps in these... 😄👍
Better than a movie. A couple of scary "INSIIIIDE!" moments, but you are singing along at an incredible pace Russell. I don't know who was inside the blue/white velomobile in the beginning but he is fast too. Can't wait until my streamliner is finished.
HPV's were seemingly the "next big thing" back in the early 1980's and into the early 1990's. Then, for whatever reason, they just kind of faded into the background. I knew three HPV builders in Eugene, Oregon when I was going to the UofO, but, they're all gone now. I wish they had made a bigger 'splash" than that.
anybody studying a field that deals with aerodynamics should be shown this. The pov's streamliner has at least twice the frontal area of the recumbent bikes, and the velos are more like 3x, and they're both just walking away from the recumbent riders. One of the guys he passes on the downgrade looked like he was doing 25ish and our guy is doing 40+ at 170w lol
Never ridden one but it looks super exciting and the fully faired bike reminds me of the ‘Dustbin fairing’ on motorbikes in the mid 50’s when they first lapped the IOM at over 100mph. Amazing speed and consistent cadence is awesome to watch and I think the video does make one feel like it’s you riding. Your approach and corner speed on the last corner before the start finish are fantastic and gave you such a slingshot down the straight it was very satisfying to watch. So if you didn’t win it Russell I am guessing top 3? Well done, loved it.
It costs me about 200 watts for 40kph (24mph) on my V20 (profile pic) on flat ground and no wind. To do 52kph on my V20 I need +400 watts. I don't have recent Strava data to show this because my bike and position isn't set up at its best now, but you can see Russell's power data onscreen to see how much power he needs in real time to get a good idea.
The UCI made them illegal to race in classics in the 30s after Frenchman Charles Mochet invented the first recumbent bike which broke a world record easily. From then, what could have made cycling a LOT more appealing to many people, and faster overall as well, sadly got very little attention.
recumbents were banned by the cycling federation a long time ago...i am not really overly sure why, except the advantage they had over a traditional bike
Because the combined net worth of all involved people is less than the ad budget for one season of F1. Plus way fewer people care about cycling in general.
This is like the F1 of cycling! Most people only care about the Nascar of cycling or the Timed Trials (regarded as one of the most boring forms of car racing, you even have to obey speed limits!) of cycling. I guess the Rallying of cycling is cool, too. 500-odd bikes start at once from the top of a mountain, the rider who is least dead wins.
Russ, is the view out for you clearer than the camera portrays? Looks manic and great fun. I did notice that your power output for 30-34 mph is the same as me on the road bike at about 20 mph, just proves what affects speed/efficiency most. PS thanks for the credit at the beginning 🙂 PPS I watched the first 2 laps then skipped bits.
Yes the view out is clearer than this video portrays, although it's not helped by the scratches on the screen from the crash at Lancaster. The only times you lose vision are when a low-racer is outside of you in a tight corner - you lose sight of them altogether....
Without engine sounds you just get gear noise and atmosphere so it sounds like a spaceship, very cool form of transport. Also one of very few ground vehicles with retractable gear.
If you notice this is a mostly flat course, given any type of incline I'd seriously doubt you'd be able to get close to the speeds maintained here. Sitting above the pedals on traditional geared bikes i imagine gives you much more power as you are able to use your body weight to generate force. I think you'd be better off with a traditional bike for standard commuting.
I wanna see these guys race against the Australians version of this sport (AHPVSS). Would be really interesting to see. I reckon we could give you a run for your money
Am I right in concluding you can average 200-250 watts and that gives you a speed of about 60kmph? If so that’s nuts! It must be hard to find places where you can maintain such speed for long duration rides to train for such a race.
You know its not that the racing isn't good, its that it needs more camera angels to capture the entire spectacle, it looks really cool from the outside and super futuristic from the inside...
This is awesome! I wonder whether it's harder to put down power in this position compared to a road bike as those power numbers are what you would see in a local C grade crit. Absolutely insane that they can hold 35mph at 200W though! Would be amazing to see the speeds a field of good A grade riders would do. Imagine Would Tour level riders!
From my experience with riding a recumbent bike you can create even more torque than with an upright bike. On an upright you push yourself out of the seat, so you are kind of limited by gravity. With a recumbent, you can push against the seat and depending on the steering geometry you can also use your arms to pull yourself towards the pedals. But it's also somewhat of a problem because it makes it much easier to put much more load on your joints.
It is understood in the recumbent community that you lose a bit of power switching from a road bike to a recumbent position. Depending on recumbent design (seat angle) you lose anywhere from 5% to 15% depending on who you ask. In my case, it is about 5% based on my Strava data. My watts/kg is not even a Cat C level, but on a road bike you'd need about 290-300 watts or more to keep up with me while I am using only about 200-210 watts. I can hold 300 watts for almost 10 minutes which will drop almost anyone, but you are right in that seeing A graders or pro riders ride these would be mind boggling. They would have to change the race courses just to make it viewable for spectators. All of them would pass by so quickly that it would make the race unwatchable. A purpose built Streamliner holds the world HPV record at 144kph. 89.5mph on flat ground and no wind. A pro rider just might hit 100mph (162kph) with his legs alone.
How much does drafting do in these races? Since you are at higher speeds but you´re already so Aero and your competition provides so little windshade anyways, I´m very curious... It does seem to help, judging by one situation where you got sucked closer to the white velo
I don't notice any draft at all off the faired two wheelers - maybe a tiny amount off the velomobiles, but I've only sat behind one at speed for a minute or so (around 27:00) and I deliberately left a bit of room for maneuvering...
This looks fun ngl. But i'm curious, what happens if you tip over? Like at a bad turn. I'm guessing you need assistance to prop yourself back up, no? And a pushing start
Sb should build a 3 seater tandem configuration (behind each other) and sit 3 TdF winners able to put out 1200 Watts continously. That contraption should be able to attain at least an 80 mph average (on a flat circuit)
@SuperZardo look for Team Sprocket Rocket , WHPV Championships Battle Mountain, Nevada. My wife was the brake/gearing stoker on the Ladies world record team. 61.94 mph flying mile. Average age of around 55 yrs. Captain was the fastest human cyclist ever at Bonneville (183.93 mph). Stokers included two track cyclists with world stripes and two distance cyclists.
Aerodynamics is everything, so... I doubt that anyone competing in a world championship will mount a camera out where it's going to generate drag just for better production value or more clicks on TH-cam. The video documents the event, which is the objective: The video itself isn't the objective, or the reason for competing.
Skin friction, rolling resistance, and drivetrain losses are not exactly negligible, but frontal area dominates for streamliners like these. To a first approximation, air resistance is proportional to velocity squared. So if he's limited now by P = k * 36^2 or sqrt(P/k) = 36, then doubling P would allow an increased speed by a factor of the square root of 2 = 1.414, which works out to about 51 mph sustained.
