I got this 36-40?? Monark Rocket and a Sears portabike. I added the seat and light to the Monark (going to replace the tires with some Goodyear DoubleEagles. The seat was recovered with the leather from an old "doctor's bag". The textured leather is cool. How about that kickstand. The Sears (72) has a 3 speed and can be taken down to 2 separate pieces. It has racks and a cup holder, perfect for the neighborhood treat runs.
