I am a student at the technical university in Delft (Netherlands) and I am designing a product for a bicycle company aimed at bike messengers. For a little general information I have set up a very short inquiry online. I would like to ask you to fill in this short form for me if you are a bike messenger and you have the time. It would be of great help for my research. The enquiry is totally anonymous and will not take more than 3-5 min to fill out. Thank you very much and good luck!
