It looks like a most awesome place to get a good view of the city as the parentals pedal along. It's a great reminder to think outside the box and not to be afraid to build exactly what you need. Check out all the details at the two wheeled hacker blog, Bike Hacks.
(p.s. Yes, we know, kids should wear helmets whether they're riding bikes or are passengers.)
