OK, this is pretty funny. Middle aged man on a bicycle pedaling away on a dyno, while he's cheered on by Mrs. Cable Guy and the rest of the team. The result is a reported 0.74 horsepower. Can only guess what Lance Armstrong might do, but we digress. We suppose the subject's name is Phil, as that's what the title says, but other than that, we have no further info on who these people are or why on Earth they felt the need to do this run, let alone film it and upload it to Streetfire. But hey, more than 2,500 clickers can't be wrong. If you have other similarly bizarre dyno pulls on tape, please share.

Thanks for the tip, dubbedinenglish!

      Isn't this Autoblog? How about exercising some discretion in what you post...
      • 8 Years Ago
      Ummm, yeah. I'm speechless.

      You know, this could be a cool contest: Guess how much horsepower Lance Armstrong would make on a dyno. Now where did I put Lance's number?
      • 8 Years Ago
      I think the actual number is much lower for continous pedaling. Maybe right at first. People aren't that powerfull.
      • 8 Years Ago
      2 hp peak probably
      • 8 Years Ago
      I have done this at my old college on a dyno I installed. I got around 1.5 hp and all of my friends were in that range too. That was on a mountain bike with a front suspension and soft tires, so it could likely be better.

      Handlebar mounted sensors that measure watts are a pretty common training device in the elite cycling world - Powertap is a brand name of one of them. Trainers evaluate cyclists on watts produced, heartrate, miles covered etc. and constantly adjust their regimen.

      With telemetry, the power output in watts is reported in real time during televised cycling coverage, along with heartrate.

      Do a Google search on "Lance Armstrong" watts and you'll see several articles.

      i wanted to put a horse on a dyno....

      Add intake and exhaust will bring him up to at least 30.74HP. Maybe add a wing and a few stickers for an extra 10 - 20 HP.

      I'm not 100% sure of the conversion to watts, but I think .74 horsepower converts to around 550 watts. This is actually pretty good and the guy on the bike sure didn't seem to be working that hard. I believe the peak output from an elite cyclist like Armstrong is close to 1000 watts. The guy in the video sure doesn't look like he's climbing Alpe d'Huez.

      Well, that's wheel horsepower, you have to account for transmission losses. =)
      • 8 Years Ago
      I'm pretty sure 746 watts = 1 hp, off the top of my head. I think in a full sprint, the top sprinters are doing 1200 watts. On a tough mountain stage, I think they average like 250-300 watts.... that's a lot of power to maintain for 4-6 hours. I'm sucking wind after only doing 150 watts for 30 minutes!
