EZ Detail Brush is for motorcycles. People love to clean the wheel barrels with this brush and I'm sure it works quite well.
Personally, I use a wheel brush which I purchased from AutoZone on the wheels themselves (the brand says AutoZone as well, but I'm pretty sure it's made by Carrand or Laitner).
For wheel barrels (inside the wheels), I use an S.M. Arnold Spoke Wheel Brush, the long version. It is very long and is on a bendable wire. The bristles are stiff so they have good scrubbing power but the diameter of the bristles is narrow...makes it easy to get inside the wheels but the actual contact area is small. Works on lots of wheels for me, but you can also pickup a brush like this from AutoZone for like $6 that has softer and longer bristles, which offers less scrubbing power but a larger contact area.
