Didn't see this thread until now for some reason. Since I built it custom for a local delivery service, I posted this in the sticky thread also, but it seems more appropriate in here.
I call it The Truck. It is almost 11 feet long with an 8 foot wheelbase, it will carry 12 common plastic tubs for a gross vehicle weight of 500 lbs. The rear wheel has zero dish and uses a special 14mm BMX axle with a 6-speed cluster. The kickstand can be remotely operated by cable with a special pull handle mounted atop the stem. Chain slap is minimized with a layer of UHMW beside the chainstay. Mostly made with materials and bike components rescued from the landfill.
