I am building bikes in a small shed in the forest haha. No constant 120v power but I wired (4) 6v golf cart batteries in series/parallel with an inverter. Solar keeps them charged and I have a kerosene heater keeping me warm-ish. Also have my RV parked here so it's were I'm livin and that beast has a nice new Onan generator. The generator runs my small welder with ease. Sometimes I'll work on bikes inside my motorhome too. Just make due with whatever ya got I guess.
