A Heavy Duty Trike

This trike needs large cargo pods on the rear sides. And it needs two usable gear ratios [one for steep hill climbing] with a stronger drive chain if there is still a way to shift between gears in a Two Speed Gear-box.

That is really all that is needed here. The seat is a bit steeper than it was made for, but I don't want to find falt with every thing. Then cover the whole thing in some kind of transperent yet very strong material.

I also recommend 16” Motorcycle tires (20” O.D.). It's about time the bicycle industry joined the rest of the machine world in using sealed cartridges; in hubs made for 600lbs total combined weight.
