12V Straight DC 
Motors with no gearing.
These are basic DC motors, just as the title claims. These are a 12v Motor directly DC motor with no gearbox whatsoever.
We offer these simple motors in assorted power ranges at 12VDC motors which are appropriate for our range of DC Speed controllers.
With no 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 created for scooter or go-kart use, these are a popular range for hobbyists and inventors.
While these are low cost motors, there is nothing cheap about the product quality. They are simply motors that are created in such large amounts they can be produced with a low price point.
The are produced in bulk, so while its expensive to get changes made (quantity must be purchased) the share motor is low cost because of its availability and widespread use.
