Tricycles

I looked up tricycles to support my design. As a result, I guessed most tricycles are used for short journey or not many people / loads. That was exactly what I thought about my elephant fire engine. What surprising me was some of tricycle's front seat design was very similar to my design.

When I went to copenhagen last thursday, I found interesting design of tricycle.
Normally space for loads is back of the front seat, but it has big space in front of handle.
It was interesting because it looks  combined with pram and bicycle.
