12V Directly DC Motors with no gearing.
These are simple DC motors, just as the title declares. These are a directly DC motor with no gearbox whatsoever.
We offer these basic motors in assorted power ranges at 12VDC motors which are compatible with our range 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 medium torque with higher speeds!
While primarily made for scooter or go-kart use, these are a 12v Motor popular range for hobbyists and inventors.
While these are low priced motors, there is nothing cheap about the quality. They are simply just motors that are made in such large quantities they can be produced with a low price point.
The are produced in bulk, so while its expensive to get adjustments made (quantity must be purchased) the stock motor is low priced due to its availability and widespread use.
