12V Directly DC Motors without gearing.
These are simple DC 
motors, just as the title claims. These are a directly DC motor without gearbox whatsoever.
We offer these basic motors in assorted power 12v Motor ranges at 12VDC motors which are appropriate for our selection of DC Speed controllers.
Without gearing, these universal motors are created for scooters or e-bikes using belts and chains (with varying size sprockets) to create high torque or moderate torque with higher speeds!
While primarily designed for scooter or go-kart use, these are a popular range for hobbyists and inventors.
While these are low priced motors, there is nothing cheap about the product quality. They are simply just motors that are made in such large quantities that they can be created with a minimal price point.
The are produced in bulk, so while its expensive to get adjustments made (quantity should be purchased) the share motor is low cost because of its availability and widespread use.
