Winches have always been a luxury item for people within the urban skiing world because of their high price and the invention of banshee bungees. But even though Banshee bungees are a close second they don't come close to the unbeatable ease and consistency of speed that a winch offers.
Recently I was watching Je Vais Au Reve the film by Awone films and as seen here at 14:48, Awone have been able to make a winch out of a pocket bike. I was wondering if anyone else has done this? what kinda bike do you need? How much horsepower, speed, etc, and what are the advantages & disadvantages of using a pocket bike as a cheap alternative?
put a pulley on the rail and use your car to tow. also get a power inverter and boom your car becomes a generator too for lights with two built in halogen lights. cars are the perfect urban accessory. best part is you probably already have one.
