I built this trike. It is fuctional, but is too hard to control. I plan on moving the turning axis forward. Sorry, the page won't upload the jpeg.
Welcome wheelburro, when you say cargo bikes, is that a bike with an extra long frame so that you can get bigger panniers on the back ???
It's a cyclos. There are two 20" wheels in front and a 26" wheel in back. Right now it has a negative turning axis, but I am working on a positive turning axis with an idler arm. I tried compressing a jpeg of the trike, but it didn't work. You can see a pic at El Wheelburro on facebook.
How long? I've been working on cargo trike design for a year. I'm moving the turning axis forward and putting two wheels in the rear. I'll post a pic when I finish fabrication.
What do you mean by moving the turning axis forward? Are you moving the front tires out away from the headtube and more forward on the frame of the seat carrier. So they are towards the front corners? Also why are you adding a second rear tire? More weight capacity, or stability. My wife saw that picture and has decided we are going to get one of those, so she can ride with me. I told her that a nice electra towny or something of that sort would be better for her. She then said no because it looks much more comfortable to sit on a seat while I pedal her around, instead of sitting on the handlebars while I pedal her around. I finally figured out that she doesn't plan on doing any of the work, she just wants to be with me when I ride.
New Model of Wheelburro with turning axis in front of wheels. Here's a photo of a new model of Wheelburro. I changed the turning axis. It's about 4 inches in front of the front wheels. It turns a lot better.
Ashivon; No problem, the seat is adjustable and the handlebars are adjustable. You would have no trouble riding this trike.
Nice, are those tubes for fishing poles. I could see turning that into a pier bike. Seat and tackle storage with canopy up front. Poles in the back.. Cruise down the pier and When you get where you are going drop a line and sit in the shade waiting for a bite. I could see you making some money in a niche market with that thing.
Grape Ape, Good idea. The tubes are for rakes and shovels and brooms. This trike is being used for gardening at a University.
