Boolean Attributes

This website currently implements six different types of attributes: Value, Values, Boolean, Category, Location and Range.

Boolean Type

Boolean is a term that means something that is either true or false. Boolean attributes are used to describe whether the bike has some characteristic or feature, such as does the bike frame fold (Frame Is Foldable) or does it have fenders (Has Fenders). The value of a boolean attribute is often displayed as yes (true) or no (false).

See also: Category Attributes, Range Attributes, Location Attributes, String Attributes, Value Attributes, and Values Attributes.

Boolean attributes do NOT have an associated unit of measure.

Search Criteria

When a boolean attribute is used as a search criteria, you can specify you want the value to be true or false. For example, do you want the bike frame to be foldable (true or yes) or not foldable (false or no). If you don't care whether it is foldable or not then don't add that search criteria.

Missing Attributes

We want to have a value in our database for every attribute for every bike model and frame size but in some cases that information is not provided by the manufacturer or other sources. In that case the attribute does not have a value which we refer to as missing. Missing is not an attribute type, but rather a possible value for any attribute.

Search Criteria

Most attributes are missing values for at least some bikes. When you add a search criteria for an attribute that has some missing values, the percentage of missing values is displayed and you are given the choice of including bikes where that value is missing or excluding them. If the percentage of missing values is low then the choice will not have much impact either way. If the percentage is high, however, you may want to select the "missing" option to include bikes that are missing that attribute.
