I think these are only desirable by decorators and people on Giligan's Island. There is a legit company (Panda Bikes) that makes legit bamboo bikes, this bike looks to me to just be a bike wrapped with wicker. If people are seriously getting more than $100 for a crappy old 3 speed bike with vines on it, then I'm going to start wrapping bikes and flipping them.
Thousands? haha, sure. Maybe people are asking that, but I don't believe they are getting it.
