The rear wheel assembly with 36 volt hub motor for the Razor Rambler 16 electric mini bike comes complete with the hub motor, wire-spoke rim, brake assembly, axle, inner tube, and a 16x3.55 pneumatic tire.

Using an electric hub motor as part of an electric bike's wheel assembly is an old idea that is enjoying a new renaissance of popularity. Without a separate rim or other superfluous parts, these hub motor/drive wheel units allow lightweight power in a small package.
