Abstract
A bicycle wheel rim includes a rim having a hollow inner part and an outer part which is integrally formed with the inner part. An opening is defined in radial direction of the outer part. A connection unit is formed in the outer part and includes two seats located at an inner bottom of the opening, and two sidewalls extending from the two seats. Two engaging portions are respectively formed on the two seats and located apart from each other. Each sidewall has an outside, an inside and a top face which is connected between the outside and the inside. The inside is a flat inside without any lip or flange. The sidewalls have better strength and protect the sidewalls of the tire from being deformed.
