This is the coolest Halloween bicycle on the Internets. I have no idea if this bike is rideable, but that skeleton looks super spooky. I'm inspired to do a Halloween DIY and get my own bamboo steed ready for tricks or treats.
A glow-in-the-dark version would look amazing and remind everyone how important it is to be hi-viz, even in death.
Just break apart the bones and secure the pieces to your frame with zip ties.
