Long time high level rower here. Why make a new rowing machine when Concept 2 is the calibration standard all athletes use and has a relatively open USB interface? For those not in the know, rowing machines all have different calibrations. C2 is the standard because they're very consistent across machines and are by far the best made allowing for many thousands of hours of use without failures. Most experienced rowers won't touch anything other than a C2. Edit: reading further, the 'moat' here appears to be electrically controlled 100lb high resistance settings. Be VERY careful with this. It's well established that most non-trained athletes will hurt themselves with this feature as it's a common trope on C2 machines. The rowing posture can be rather dangerous for high weight if misused.

This was my query - it’s almost impossible to replace the concept 2, as it’s the de facto standard for splits and 2k times etc. Add to that, I recall us racing the ergs on a virtual lake on a tv as far back as 2000 or so - made doing 2ks way more interesting, as you could compete with the rest of the crew directly.
ADominic 6y ago
also a former rower - I don't think we're the target market. If you've never touched an erg, it might not really matter whether you start on a C2 or not. And I'd guess controlling the hardware also gives them more control over the entire user experience + their own costs.
- AWildC182 6y ago
  I see this as an insanely dangerous game. IME most non-rowers won't touch an erg without significant instruction/encouragement as they're technique dependent. Any that do will quickly figure out from anyone who has rowed that C2 is the standard and everything else on the market is flaming garbage. Add to this that I could recreate this business using the C2 API in a couple weeks and suddenly have a market of everyone who owns a C2 (all the people in this thread complaining that it doesn't support their machine) along with a literal potential customer list available through C2.

    You make a good point re: the C2 market. I mentioned up top that a huge part of our experience is the electronically controlled resistance that adds up to 100+ lbs of force. Our high-intensity games and strength content, which differentiates us, requires this and the reason why we opted to build our own rower. Thanks for the feedback.
    - AWildC182 6y ago
      Edited my comment when I saw this. This is exceedingly dangerous. Ask any rower that's worked with people on C2 machines. Everyone will instinctively throw the damper to setting 10, then throw their back due to bad posture.
      - Alex3917 6y ago
        > Everyone will instinctively throw the damper to setting 10, then throw their back due to bad posture. The people who do that normally only row for a few minutes at a time, and aren't really at any significant risk of injury. The only class of people who seem to consistently develop back problems from rowing machines are people who train on them for hours a day in high school and never lift weights. All the other back injuries in rowing are usually from either sweep rowing or from lifting.
        AWildC182 6y ago
        The standard rowing machines (sit on sliding seat, feet stationary) can actually be pretty abusive to the spine, worse than scull or sweep. I've seen inexperienced people actually hurt themselves. It's mostly an issue of shock at the catch and finish. Dynamic machines such as those made by C2, Row perfect, etc are a bit better in this regard and might be a better fit for this market.
      - FullNameAndy 6y ago
        Good point. We do our best to educate users with intro rowing videos that can be found on the touchscreen. Any any time the resistance is at a high level, we use little animations that show proper form and technique.
- rloomba 6y ago
  fwiw i'm actually not a former rower and I just purchased a C2 after some very light research. It's the industry standard, it's relatively cheap, and ALL of the apps are specifically designed or have have seamless integration with the C2.
  - FullNameAndy 6y ago
    It is a great machine - I have one too :)

Most experienced rowers won't touch anything other than a C2. Most colleges also have a few Gamuts around. I actually think it would be really fun to do quarter mile sprints against real people on a Gamut-type erg with these kind of screens.

  Hey Alex, you are right, most experienced rowers won't touch anything other than a C2. But there are a ton of people who see the benefits of rowing but aren't interested in the C2 for various reasons. We feel we have a great alternative for those people.
FullNameAndy 6y ago
Great question and ADominic answered it well. The C2 is an amazing rower, I have one too. We don't target the hard core rower. And a huge part of our high intensity experience is the electronically controlled resistance that adds up to 100+ lbs of resistance. Our rower automatically adjusts the resistance depending on the workout and your goals.
- AWildC182 6y ago
  Why vary resistance? Most athletes learn to handle one resistance setting, the National Team standard being IIRC DF120, though anything between 100 and 120 is fine. Changing it tends to throw people for a loop.
  - FullNameAndy 6y ago
    good question. Aviron's resistance settings are used to enable high intensity interval training (HIIT) and workout variety for the average person/ fitness enthusiast. For example we have strength programs that guide you through bicep curls using the bar (with an animation that shows feet firmly planted on the ground and a low and steady motion, if you're moving too quickly Aviron will sense it and tell you to slow down your movement)
  - sleepydog 6y ago
    I rowed in college and have countless hours on concept 2 rowers. Outside of very specific drills I picked one weight setting and stuck with it. If I wanted to vary the difficulty I just rowed faster. I don't think varying the weight is good for your form and it could be dangerous for your back if your form is bad. After all, you can't vary the resistance of water in a real boat (I suppose you could pour gelatin in a lake). Intensity could be varied just by changing the stroke rate.

phjesusthatguy3 6y ago
I've seen numerous ads for Peleton; I have no idea what Concept 2 is, much less some ad on YC for yet another YC product I'm not going to buy. In addition, I've seen at least one New York Times article (each) wringing their hands about Biden riding a Peleton and wearing a Rolex, like it's surprising that US Presidents are inordinately rich. Anyway, I'm gonna get my fat ass back on the hydraulic rowing machine I have stored in my basement before I buy anything else from anyone.

Not only does the C2 has an USB interface, but recent models have Bluetooth as well...! (I'm a happy C2 owner) I found an example project some time ago of a web site using Chrome's Bluetooth JavaScript API to recreate a rowing monitor and filed it away in case I would ever get to that side project :-) In case someone's interested to collab: I would build a 3D world through which you row. I know apps/games like these exist but an open version would be great (also the ones I found seemed to have so-so 3d graphics). And compatibility with VR headsets too..! Just to add to this: an Apple TV-compatible, 3D rowing app would be supremely interesting to consider...

  I'm pretty good about going out to take a walk/hike pretty much any day when the weather is remotely tolerable. But exercise equipment really does bore me. My C2 is 15+ years old and I don't use it a lot. But I'd upgrade the performance monitor in a heartbeat if there were a way to use it in conjunction with an Apple TV for a non-subscription immersive experience. (Something in the Hydrow vein.)
  - gregsadetsky 6y ago
    You'd still need the monitor (what Concept2 calls the "PM5") to send Bluetooth data to your Apple TV, but you could fold the arm so that the monitor wouldn't be in the way of your tv. I totally agree with you, rowing while even just watching TV is a lot more enjoyable. Having anything interactive (games/immersive) would be really great. Re: subscription, I agree that it'd be interesting to build something for free that everyone can use, and maybe try to sustain this with subscriptions for extra features (competitions, etc.) Finally, maybe the trick to building this out rapidly is to start with a web version. You'd connect your C2 to your computer via bluetooth, and then you could stream your computer to the Apple TV. A native Apple TV app would be better though, but it's more work. A web/three.js prototype is faster to put together (for me, at least -- a Unity developer might want to do this natively) Should I try to make a launch page and if I get 1000 emails, go off and do it hah? :-) --- Actually, an iOS app that would run on iPads (the perfect-ish format for a C2 immersive monitor) is really interesting... Maybe iOS/AppleTV is the way to go after all...

C2 is really an engineering masterpiece. Simple, works forever, cheap replaceable parts, anyone can do the maintenance after watching a YouTube vid. Also super cool that you can upgrade the display/head unit w/o having to get a new rower. It's also significantly cheaper than this machine and has exceptionally high re-sale value.
- FullNameAndy 6y ago
  You are 100% right, the C2 is a tank. I have one too. But the C2 might not be right for everyone. I think we might be able to get more butts on rowers if we can make the experience more enjoyable for those who aren't motivated by the C2 and its current content.
- bob1029 6y ago
  The C2 is the best machine I've ever purchased. Ive got 3.6 million lifetime meters on mine, and the most I've ever done to maintain it is wipe down the rail/rollers and put some 3-1 oil on the chain.
