Cycle Circuitry

The benefits of cycling are obvious: exercise, pollution-free travel, and enjoying the outdoors. But what if it could also power your mobile devices? With the Atom generator, that’s not just a wish; it’s a reality. Created by the smart folks at Siva Cycle, the Atom charges electronics using the energy you create. As you pedal, you’re powering a generator that can charge a mobile USB device like a smartphone, GPS, and more. It’s lightweight, splash resistant, and the battery pack detaches easily for on-demand power. This bicycle phone charger is easy to install, and is the cool factor is high. Entrepreneurs Aaron Latzke and David Delcourt started Siva Cycle to transform the latent power of bikes into usable energy. They want to power the world one pedal stroke at a time. Now cycling is more than a green way to travel. It’s also a green way to charge up.

    I agree with Bonita, but even when there is no power outage, this needs to be a device for home exercise machines. Can it be attached to other things besides bicycles?

    David – Special Guest
    2/26/2015 12:28 PM

    @Amy right now it's designed for a bicycle, but if you are able to put it over an axle of any sort, you could use it. We are working toward fitness-oriented versions, just not available yet.

    What is the energy expenditure vs how much charged? Say I pedaled aggressively for 45 minutes, averaging 18mph, how much (best guess) would a standard 5v device have been charged? I think it is really cool that this idea has come to fruition. Will be great especially for my rechargeable lights. I can also let my hamsters rest as I have been trying to get them to power many, many things in my household. I guess it is now up to me ;)

  • David
    David – Special Guest
    2/26/2015 12:38 PM

    @Cass you know, that hamster idea may have legs! To answer your question, you'll get about 1% per minute at that rate, about 0.5% per minute if you're just cruising along. That's going to be same as if you plugged into the wall. In perspective, for most lights, if you rode for about 5-10 minutes you should have enough juice to get you through the night comfortably. For a phone, 5-10 minutes translates to a couple hours of phone power.

    I see by the video that it's good for tour bicycling, which is the kind of riding I do most. However, I find myself on lots of rails to trails systems and by the end of those rides there is quite a lot of dirt buildup from the crushed stone, etc. How do you think The Atom would fair in those types of conditions? Considering we camp most nights, providing our own charging power is an amazing option.

  • David
    David – Special Guest
    2/26/2015 12:47 PM

    @karen our early users have not had an issue with dirt...and from our experience, it can take quite the beating! The unit itself is sealed so long as the USB plug is installed and is IP-4 weather resistant (just don't go swimming with it!). In the case where there was some dirt buildup in the battery pack area, you can wipe it off with a cloth of sleeve. And yes, we have had a lot of interest from the touring cycling world, including using it ourselves!

  • David

    2/26/2015 12:48 PM

    @Ami yes, it will Ami. You'll just want to be sure there is enough resistance on the trainer to not spin the generator too fast. It's not meant to be used at non-realistic (motorbike for instance) cycling speeds. I use it on my cycleops with no problems.

  • David

    2/26/2015 12:49 PM

    @MJ quick releases are no problem! The video shows installation on a through axle, but there is a quick release mounting video on our website too! We designed the product to work with both!

  • MJ
    MJ
    2/26/2015 12:51 PM

    @David I'm more curious about theft. If someone were to release the wheel, do they also require a special tool to remove the unit? Thank you.

  • David
    David – Special Guest
    2/26/2015 1:00 PM

    @MJ there is no special tool now, no. We encourage anti-theft bolts OR much easier, a good U-lock for the back wheel! So long as the wheel can't be removed from the axle the unit is safe. The battery pack does remove every time, similar to how the old car stereos had the face-plate.

  • James

    @David

    1. At what bicycle speed does this begin to generate electricity? 2. I too am a tour rider and I carry an iPhone and iPad on bike trips. Will the battery charge both?

  • David
    David – Special Guest
    2/26/2015 1:20 PM

    @James you can charge directly while you ride AND from the battery pack when you are off the bike. Charging starts around 5mph and will continue to draw 10% or less of your effort, no more. The phone is the native charge rate. The battery will charge at 800mA which is lower than the iPad will ideally like...so yes it will charge the iPad but at a slower rate than plugged into the wall. Thanks!

  • David
    David – Special Guest
    2/26/2015 1:27 PM

    @Mary yes indeed, it will work globally. The power is on the USB platform, which is not dependent on the power coming from the wall. Rather, just the USB to micro USB (android/windows phones) or USB to Lightning (iPhone) is needed, not the outlet to the wall. You are good to go!

    Good afternoon. I am interested in an electric bike. What is your opinion about using this device on an electric bike? Would the electric bike produce too many RPM's for this device?

  • David
    David – Special Guest
    2/26/2015 2:15 PM

    @Lynn there are two issues to content with really. First, as you mentioned, some electric bikes go upward of 30 mph. The Siva Atom shouldn't be used extensively above 20-25mph. Secondly, there is the issue of efficiency...you'll use your battery up about 10% faster with the Atom attached (though you can charge your phone!). Hope this is helpful and good luck!

  • Mary
    Mary
    2/26/2015 4:59 PM

    This is a great idea. I think it could be used to power up a Spinning ( cycle indoors ) class. It could generate enough electricity for the lights in the room perhaps?

    I think I saw something like this on line in China. Not sure if it is the same idea. Check before you patent. Good luck! I am impressed.

  • David
    David – Special Guest
    2/26/2015 5:14 PM

    @Mary thanks, we have filed a utility patent! The technology is quite different from what else is available (though power on the bicycle has been around since the 40's). We're investigating spinning and fitness applications, but for now it's focused on riders getting around by bicycle on a regular basis. Thanks!

    I'm a wheelchair user. Have you thought of making one for wheelchair users specifically? If not and might because of my recommendation I would love to test it out! I use a TiLite ZRA with the ADI breaking system. I'm unable to ride a bike and as the video says this is my biggest problem with my mobile devices!

  • David
    David – Special Guest
    2/26/2015 8:35 PM

    @Sarah thanks for the note. We've had a number of requests for wheelchairs and in our tests, the issue has been 1) the size of the axle, which is generally larger than that of a bicycle, and 2) whether you can easily remove the wheel or not. So far we haven't tested many, so it's entirely possible it could work. Do you know the answers to the above questions? I will also look into it. Thanks!

    @Thomas unfortunately the Atom does not work with disc brakes. We are working on a version for later this year that does, but as of now, the Crux does not have enough room on the front fork to fit the Atom.
