Quarterbakery idea: bike chair.
- chair that folds out of side of bike when your not riding it, to be used for comfortably resting. Instead of tying the bike and leaving it, lean on it for support!!
Here's how I drew it in Deviant art
There's a feature to see how it was drawn, and in it you can see the chair when its folded.
This drawing was started from a realistic 3d simulation of another Quarterbakery and Halfbakery idea of mine - the Pedal Assist.
