I used 40 size 2 diapers, 1 bottle, 2 bibs, 2 pairs socks, 2 receiving blankets, rubber bands, tape and ribbon.
First, I made two stacks of 20 diapers each. My package of diapers had 42. Roll up one of the extra diapers and tape the ends.
Start wrapping one stack of diapers around the rolled up diaper and put a rubber band around it. 
Keep adding diapers in this fashion until you have all 20 diapers. You have just made one wheel!
Now you can take the center diaper out. (This just holds the spot that the blanket will go in later.) Next, do the same thing again for the other wheel.
For the first motorcycle, I covered the wheel with a receiving blanket, but this one, I just wrapped each wheel with ribbon and either tape or glue it. I think I like it best with the ribbon.
Now, take one of the receiving blankets and fold it until it is about 3 inches wide. Slide the blanket through the center of one of the wheels and then through the center of the other wheel too.
Take the ends of the blanket and using another rubber band, secure the ends of the blanket and tuck them neatly in the center of the wheel.
Lay your bibs on the top of each wheel and put the bottle on the front wheel, on top of the bib. Then, take the other blanket folded in the same manner as the first and run it through the middle of the front wheel.
Pull the ends of the blanket up, making sure they are even, and secure with a rubber band on top of the bottle.
Now for the handlebars. I used two pairs of socks, but on the first one, I layered several pairs of socks because of the package of socks we bought.

Next I made a bow with coordinating ribbons to hide the rubber band on the handle bars. I think they look best with a stuffed animal or doll riding on it, but that is up to you!
OH, in case you need an idea for that extra diaper...... Kailee recommends this.....
Poor dog doesn't stand a chance! At least she cut a hole for her tail this time.
Hope this helps. If you have any questions, let me know!
