Bike + bike trailer has great utility, especially after the BOV runs out of gas.
Here's one of my mountain bikes pulling a dog trailer (holding two puppies). That is a "Croozer" brand dog trailer rated to carry 100 pounds. There's also a luggage rack that fits on top of it and there's a third wheel and handlebars so it can function as a stroller.
There are a number of strictly cargo trailers to choose from. A child trailer would also hold a fair amount.
I'd enjoy a thread on non-motorized BOVs.
Thanks for the tip Dagny. I did a quick search and found the Croozer Cargo model on Amazon for $179.99 shipped. Doesn't seem like a bad deal to me since it seems well put together.
For anyone that cares, the interior dimensions are 30.5 L x 19.5 W x 13.5 H (inches) & capacity is 66 pounds.
