Having just returned from the amazing Velorama bicycle museum in Nijmegen, Netherlands, I thought I had seen pretty much every weird idea in cycling. Apparently not as up until now I have never come across deer antlers turned into bicycle handlebars. These come from Taylor Simpson, a designer in New York and you can check out his M-O-N-I-K-E-R handlebars here, although there is not much information about them.
For several reasons, I can imagine as dramatic as they look there are some drawbacks to this idea. I am sure the first pedestrian you pierce will point these out but I also think in the event of an accident you are going to risk getting pierced yourself as the rider if they shatter. They do look cool, though.
