Query: Disappointing Quality

The is a classic toy. I remember mine as a kid, and recently bought one for my two year old daughter. While assembling it Christmas Eve, I was extremely disappointed with the quality of the parts that are included to put the bike together. Two flimsy "cap nuts" are supposed to be hammered onto the end of the rear axle to hold the tires on. These simply keep falling off, along with the wheels. Real fun. Also, the pedals are supposed to be hammered on and held in place with "lock washers". One of the washers snapped and so the pedal fall offs too. The manufacturer could easily throw a couple extra of these fragile parts in the box--especially when the design is so poor.
