MAKE Flickr photo pool member Pekar writes – “I started out making a kids’ cargo hauler, but it ended up a tandem. It only took one day. I had to weld them together, and fabricate the dual chainring. The top tube just bolts onto the seatpost clamp. It’s hands on shoulders for the stoker. Next one will be a 20″ wheel, so older kids can use it. This one might be a bit much, we’ll see. An adult can ride on the back and pedal on the front.” [via] – Link & bicycle hacks set.
