Oliver Klein Kanguru bicycle child seat and backpackDesigner Oliver Klein’s Kanguru reimagines the bicycle child carrier as a multipurpose device that transports your tot as well off the bike as on.

Anytime we can consolidate tools into as few pieces as possible with as many functions as possible, we’re pleased. The judges at the BraunPrize 2012 contest, themed “Genius Design for Everyday,” agree and awarded it a Gold.

The Kanguru’s parts are easily removable and replaceable. This makes cleaning a snap, an important feature given the intended cargo, and also makes it easier to replace a broken or worn part without sacrificing the entire unit. This, combined with it being made almost entirely of recyclable materials, reduces its ecological footprint.

The frame is designed to fit a range of people thanks to adjustable straps and harnesses. On the bike, they snap into each other to stay out of the way of wheels, gears and legs.

Disassembly is easy and tool free.

A custom rear bike rack is conceived as part of the product. These renderings show it to be very much like the rear wheel skirt guards on Dutch bicycles.

It’s designed so the child may remain seated inside the carrier when transitioning from walking to biking and support them even while (they are) sleeping. The cherry on top? It stands upright on it’s own on flat ground.

  1. I wonder if anything has ever been listed on this site without some genius finding something wrong with it. Ever.

    If only those silly professional designers would submit their product ideas here and benefit from the vast pool of design expertise available, free of charge, from the readers of BikeRumor.

  2. The latch on the bike rack securing the “carrier.” How do you reach around the carrier to the back of the rack, sitting on your bike with a kid in it?

    It’s a great idea- that part could be improved ATMO. Critique is not a negative in product design. Those who don’t understand that probably “can’t do” either.

  3. Why would you be sitting on your bike when you latch or un-latch the seat? You take the back-pack off to put it on or off the bike. So the latch is fine.
    Now, IF it was designed so you could get on your bike with the pack on, attach it to the bike and take the shoulder straps off, and do the reverse upon reaching your destination, THAT would be freakin’ awesome! But nowhere does this design claim to do that.
    It would be great if this fit into a car-seat base, too, though in Europe I can see that being less of an issue, and the cost of the lawyers would probably make it a non-stater.
