Classification of bikes (1)

One of the basic aspects of highway geometrics is to design for the vehicles which use the roads. To help with this, technical guidelines often include details for “design vehicles” – average or typical dimensions for a vehicle in a particular class (car, truck, bus, etc.).
So far as bikes are concerned, the guidelines generally only refer to the “standard” two-wheel bicycle.

However there are many different types of bike. And regarding sizes, some bikes are even wider / longer / or higher than an average car.
This gives us two questions (which apply also to other vehicle types, and not just to bikes):

  •  how can bikes be classified
  •  what are the typical dimensions for each class of bike

One way to classify bikes is in terms of the number of wheels which the vehicle has.

I created a short document on this topic and uploaded it to Scribd. You can view the document or download a free copy from this link.
