Cargo Bikes

@user67706akajimmythegrin great project, but my comments would be the same as @AngusMacGyver. Even with the revised frame (unless it's still work in progress...) the front end needs more support under vertical load otherwise it will flex loads and eventually fail. Look how deep the sections are on Bullitt bikes for example and like AngusMacGyver's repurposed Muddy Fox above. Pedal clearance would be a concern if it's still the same as your photo above...
Keep it coming though... :)
