12V Directly DC Motors with no gearing.
These are basic DC motors, just as the title says. These are a straight DC motor with no gearbox whatsoever.
We offer these basic 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 12v Motor 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 priced motors, there’s nothing cheap about the quality. They are simply just motors that are made in such large quantities they can be created with a minimal price point.
The are manufactured in mass, so while its expensive to 
get adjustments made (quantity should be purchased) the stock motor is low priced because of its availability and widespread use.
