The "Truck-cycle"

I remember, we used one of those with an open top when we delivered a refrigerator to our place. It pulled pretty decently, but I wouldn't recommend regular overloading 'coz the engine sounded heavily strained when we used one back then.

Given its setup, I think it could comfortably seat 4 people plus a few bags. The model with a reverse gear (used by Coke) would be nice as a shuttle in a big subdivision.
