From the early 1980s Honda had begun equipping newer models with cast wheels called ComCast stating "...that technology has solved the casting porosity problem and that cast wheels are now used on Hondas for styling and marketing reasons". ComCast wheels were a combination of pressed-together cast aluminium hub and spokes with a hollow extruded

Wheel hub motors are increasingly common on electric bikes and electric scooters in some parts of the world, especially Asia. Compared with the conventional electric vehicle design with one motor situated centrally driving two (sometimes four) wheels by axles, the wheel motor arrangement has certain advantages and disadvantages: Cars with electronic control of brakes and acceleration provide more
