	The bicycle ambulance is used in rural areas of Namibia for medical transportation. The cyclists are often HIV/AIDS home based care volunteers who can now use the bicycle ambulance to help their patients access healthcare.
	I designed this trailer for manufacture and use in Namibia, as an income-generation technology for the fabricators and owners. This trailer can also be used for medical transport. Contact me for plans
	"Flatsy" without wheel guards--easier to build, lighter, smaller, prettier...uses 20" wheels.

	Bicycling Empowerment Trailer (BET), known as the "Bike Bakki" in southern Africa, with kids at a kindergarden in Katatura in Windhoek, Namibia.

	Palletes rest on the wheel guards
	A better location for the seat would be back to just in front of the wheels, to balance the weight better. This configuration will put excessive stress on the pulling arm and bike frame.

	This is the first conduit cart. The pulling arm is 2 pieces of 3/4" EMT conduit, and the rest of the cart is made from 1/2" EMT. Gears are useful.
	The two wheel guards keep things from falling into the wheels. The small handle in the back wasn't tall enough to comfortably push, so I added another. It increases the functionality but compromises the aesthetic.
	The hitch is made from 1"X 3/16" flat stock, and has a slot for the axle. The 1/4" rod braces against the chainstay to prevent the hitch from rotating.
	Clamp hitch, similar to the one used by Bikes At Work.
	The first Mig welded, 3/4" mild steel cart was converted into a farm cart and went to Food Bank Farm.
	Two recyling bins fit nicely in a cart. There's someone in one of the bins, somewhere.
	Donna pulling two bales of hay. "Deep and Long", aka quadrouple hearse, aka love-mobile, has a 6 foot long bed and potentially a 400 lb capacity.
	At the end of the summer that I spent designing bike carts in Northampton, MA, I packed up and moved by bike and bike cart. The signs say, "yes, i'm moving by bike" and "one less car". This is the first trailer that I built. It's made from 3/4" mild steel tubing and bent with a hossfeld bender, which is why the bends have a 2" radius instead of a 4 1/2" radius.
	Some friends and I made a bolted cart, which was difficult, took a long time, and was ultimately not as strong as a brazed cart. Plans for it are in the DS fabrication manual at the end.
	rebecca on ben's chopper. The fork didn't last very long, and every time it breaks it gets a little stronger.
	Eccentric wheel. Pretty tricky to ride, but once you get it you can propel yourself with your arms.
	There's just something about portable band saws...
