If you really believe that, you need to go back to tricycle school. How do you think Morgan drivers get the back end swinging around if there is no side load on the rear wheel? I'd go for a Nimbus, on the grounds of being cheap and wide enough to support a 50mm Big Apple properly on something which doesn't lean.
Edit: Just seen a Christiana style trike with a Big Apple on the back, took a good look at the rim (as good as you can in traffic, anyway) and it looked to be 35-40mm wide.
