Joyrider by Moritz Waldemeyer


Designer Moritz Waldemeyer has created Joyrider, a product that creates illuminated smiley faces on rotating bicycle wheels.

Joyrider consists of two electronic devices that clip onto wheel spokes. They measure the speed of rotation and emit LED light to create the illusion of a stationary smiley face as the wheel spins.

The devices were attached to two prototype bikes designed by Waldemayer and were auctioned at the ICA 2008 Gala: Figures of Speech last week, where they fetched £2000.

The following information is from Waldemeyer:



Rising star of modern design, Moritz Waldemeyer brings fun, colour and idiosyncratic art into bicycle engineering in his latest project, Joyrider – a revolutionary accessory that transforms a bicycle into a moving light show.

The design evokes new rave couture, with its iconic smiley face and the strobe effect, bringing kitsch glamour to the cycling experience. The minimalist components are attached to the spokes of the wheel, emitting a fixed image of a smiley face using LED lights. This effect is achieved through inbuilt microchips that are able to calculate the speed of the wheel in such a way that the smiley face remains stationary while the wheel spins.

Widely recognised as one of the most innovative and exciting designers of his generation, Waldemeyer, aged 33, was born in East Germany. He moved to London twelve years ago where he trained as an engineer at Kings College and completed his Masters degree in 2001. Since then, he has collaborated with many of the world's top architects and fashion designers including Ron Arad, Zaha Hadid and Hussein Chalayan. His work is a fusion of technology, art, fashion and design.

The photographed bicycle is custom designed by Waldemeyer in a vintage style to evoke the past when cycling was seen as a glamorous activity. Joyrider looks towards a future where new technology and design may restore lost elegance into modern life.

The Joyrider project was commissioned by the ICA and Veuve Cliquot.

    I want one of these so very badly…

  • rob

    then check:

    she did it back in 2003 and they cost about £ 20 to buy…
    without the leather case…

  • Arch

    whoah. cool.

  • Onion

    This is not new. In fact many more original designs have been made. Too bad this is a cheap Walmart ripoff.

  • the frog

    Not really new, no!
    Has been done in many occasions in all forms and shapes.

  • Davin

    The smiley face is pleasant, simple, and works well in this medium. It is sad that someone is only able to associate it with a large corporation. Evidently a victim of branding.

    Is this theftproof?

  • You have got to love Moritz! Come on guys – this has been done before, yes, and the other versions are more elaborate and cheaper but this was a charity event – where £2000 was raised from this product to go toward the ICA Fund for creative peeps. Moritz is a good guy and I personally respect him an his work a great deal – he has done some fabulous work in the past and has remained, until very recently, behind the curtain while the other ‘star’ designers bask in the limelight! LONG LIVE THE WALDEMEYER!!!

  • very cool work on site … thanks for posting that!

  • alexr appeared in 1999.

    Maybe it is not so much a problem with Moritz or the design, but rather with the press release and the statements proclaimed.

    This “design” became publicly available in 2006, as has already been pointed out by rob at 11:05 am. Was credit given? Another article published in 2006 demonstrates how to make this,

    The assumption that changing the color of a store-bought bicycle to yellow equates to “a custom design in a vintage style,” is the sort of hyperbole that shows pure arrogance by the folks at ICA.

    For that sort of statement to be true Waldemeyer could have commissioned a frame to be built by one of thousands of artisans who are still alive and making hand-built bicycles out of steel, aluminum, titanium, carbon fiber, and even bamboo. It would also have made sense to remove the labels from the rims.

    There is a simple disconnect between the press release and what Jodi says about it being a small project commissioned by ICA and VC as part of a fundraiser.

    I will continue to ride my bike sans these lightup accessories and drink Roederer Crystal from my water bottles.

  • Just a quick note to everybody pointing to all the previous work in the POV realm. Yes, many people have done various things with POV displays and I am aware of most of them. I did not try to invent POV (persistance of vision) with this project or claim the underlying idea as mine, but as far as I know this is the first and only one that can be done with just one single LED. It’s a very simple idea of a very simple circuit creating a very simple graphic.

  • And maybe a little comment on the bike, this was built from scratch from a mix of new and vintage components with the aim to create the ultimate bicycle for one very special Italian lady – simply because it was impossible to find anything like it in the shops and the above mentioned bike builders are great but very expensive.

    this really make me happy.
    cant wait for the summer Wicker Park Rides again.
    with the massive crowd of 100’ts and 100’ts riding along each other.

    nice post. great job.
