I live in Amsterdam in a apartment building on the third floor.
My bikes are standing under the building. On the ground floor I have a small place for my bicycles, tools and spare parts. It's not big enough to put my motorcycles inside and there's no electricity.
So when I want to use the grinder, etc I throw a extension cord from the balcony and start wrenching on the sidewalk.
I made some mockups with stock and old parts that I had lying in the shed.
