Brainsturm QR bike


I have a business of my own in marketing and advertising. Never build a bike. I thought it would be fun to create and build a bike to promote my business in and around the town I live and work in. So I build the Brainsturm QR bike. On the gastank (and on my helmet) there is a modern QR code you can scan with your smart-phone when you see the bike standing somewhere and your phone will open my website.


It turns out the QR code is very teasing and a lot of people scan is and visit my site. So the bike is a very good advertising medium 😉 TheBrainsturm QR bike is build from a Yamaha XS 650 ’81.


Only the engine, wheels and fork are original.

Everything else is chopped, self build or bought. I think it has a nice look and wonder what you think…


My business is called Brainsturm. This is because my name is Sturm  and my business is marketing advice in which I brainstorm a lot with clients. So it is the Brainsturm QR bike. The webadress is: (the QR code leads you there)

    Love the build, the color, and the marketing concept. I also like that you put a pic of yourself with the bike. I wish more people put pics of themselves as well as riding the bike to get an idea of the stance, pegs, handlebar location, etc.

    Too bad QR codes weren’t a cooler shape. Totally dig the bars.

    AWESOMENESS !!! I love it. The pipes are kick ass cool. I think he uses this to advertise his bizzness…? LMAO

  11. @Idaho Jared says:

    Your right about some one sitting on the bike! One of my fav things about the xs bobbers is how short and stocky they look, and when you get someone sitting on it it shows. Great looking bike! think if you black it out a bit the colour will pop.

    nice scoot. but, dude, do you really wear those shoes when you ride? you euro-cats are something else. but, hey, you built a pretty little ride.
