The price of gas being what it is, and considering what it will reach, suddenly all kinds of personal transport concepts are looking more promising. Take the Electric Bike Train for instance. In a world of skyrocketing gas prices, it’s the perfect electric bike for an entire large family.
It’s designed by Jiang Qian, and while I can’t find anything about just how many bikes can be linked up, I would guess quite a few. The front wheel connects to the two rear tires of the next unit. See, even when gas is unaffordable, you can still listen to your kids bitch and whine and ask “Are we there yet?”.
