12V Directly DC Motors with no gearing.
These are basic DC motors, just as the title claims. These are a directly DC motor without gearbox whatsoever.
We offer these basic motors in 12v Motor assorted power ranges at 12VDC motors which are appropriate for our range of DC Speed controllers.
With no gearing, these universal motors are designed for scooters or e-bikes using belts and chains (with varying size sprockets) to create high torque or medium torque with higher speeds!
While primarily designed for scooter or go-kart use, they are a favorite range for hobbyists and inventors.
While these are low priced motors, there’s nothing cheap about the quality. They are simply motors that are created in such large amounts that they can be produced with a low price point.
The are manufactured in mass, so while its expensive 
to get adjustments made (quantity should be purchased) the stock motor is low cost due to its availability and widespread use.
