Pedal Powered Clothes Washing!

Appliance meets urban mobility in this clever combination that cleans your clothes while you commute! Called the “BiWa” (short for bicycle/washing machine), the design features a rear wheel barrel where you can deposit your dirty laundry, water and detergent. After a couple miles of riding, drain and refill with clean water to rinse. By the time you’re home, you’ll not only bit fit but have fresh clothes to wear!

Designer: Barbora Tobolova

    This would have been a good idea if it were a stationary bike… Frankly speaking.

    wouldn’t i look ridiculous cycling around the neighborhood with my dirty linen getting tossed and turned in my rear wheel??

  • corey says:

    not to mention, if the side of the wheel accidentally opened while riding, that would be a disaster, no?

    Okay. Here’s the major flaw with this concept.
    I do however thank the previous people for pointing out relevant errors, but here’s the biggest one.
    There’s a reason the bike wheel have spokes. So that the wheel can flex and bend and adjust to the load of the person on the bike. Coupled with suspension, this makes the bike a smooth vehicle. People will notice that horse-carts with wooden spokes were much more uncomfortable and bumpy as compared to the modern day bike, which had flexible metal spokes.

    Now here’s where the discrepancy lies. In the design of the wheel.

    Firstly. No suspension. Which means your ride will be absolutely uncomfortable. Bad for the back.

    Secondly, the renders don’t show how the clothes go INTO the wheel. I’m assuming they go from the side (plastic rim-cap). When the person sits on the cycle, all the load goes to the plastic cover. because there isn’t any suspension either. The plastic cover has two options. Either to break because of stress, which is undesirable, to say the least, or to flex, which means it will warp and will create a small opening somewhere causing the water to leak out. Not a good idea at all.

    The third error, in my opinion, is a simple little error that increases the effort of the ride. The pedals are attached directly to the front wheel. Which means for each pedal, the front wheel (and also the back wheel) rotate once. Which means you need to pedal more, to wash more. Wouldn’t it be a better idea to have a gear based system that allows you to pedal once, but rotate the wheel twice or thrice for each pedal turn? That saves so much effort, doesn’t it?

    Thank you so much for your patience.

    good idea, but i really think that what these guys pointed out is very relevant. hope to see a more finished concept soon.

  • I prefer a bicycle like this but static; I mean, for the house. But design likes me.

  • I believe that is one of the such a lot important information foor me.
    And i’m satisfied reading your article. However wanna statement on few general issues,The
    website taste is ideal, the articles iis actually nice

    Hi there,

    this bike will require twice as much effort to operate, simply because of the friction within the wheel. it is indeed a good idea for a static bike, but not as astreet bike.

    hey, Biwa is going to be produced soon 🙂 we, just need some more technical tests.
