12V Straight DC Motors without gearing.
These are simple DC motors, just as the title claims. 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.
Without gearing, these universal motors are designed for scooters or e-bikes using 
belts and chains (with varying size sprockets) to create high 12v Motor torque or medium torque with higher speeds!
While primarily created for scooter or go-kart use, they 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 motors that are made in such large amounts that they can be created with a low price point.
The are produced in bulk, so while its expensive to get adjustments made (quantity should be purchased) the share motor is low priced because of its availability and widespread use.
