Bumblebee

Bumblebee is Yang Xiao Long's personal method of transportation. It was first seen in the "Yellow" Trailer and later in the opening credits.

Description
Being Yang's own personal bike, it shares her yellow-themed color scheme. It appears to be a sport bike, with a design emphasizing speed and aerodynamics. The sides of the engine compartment include supercharger intakes and a close view of the rear wheel whilst the vehicle is in motion show a complex high-ratio gearing in operation. These all indicate that the bike has a very powerful engine and the capability to use that power efficiently.

In an interesting variation on the motorcycle design, the bike does not have a kick-stand for balance when it is parked. This suggests that it may use some form of gyro-stabilization or have an as-yet-unseen and unspecified non-physical stabilizing system to keep it upright when stationary, though it may also simply be an oversight.

Trivia

 * Due to the glowing elements and the fact that the world in RWBY is very dependent on Dust, the motorcycle has been theorized to run on Dust.
 * Yang's look while riding it consists of a yellow biker's helmet and yellow-tinted goggles.
