Tanasha Kirton –
It provides more than enough power to propel a lightweight electric bike at a decent speed. I used it with the motor controller and battery pack, and it ran very smoothly.
Shamita Tanwar –
It’s great for low torque, small jobs like turning small wheels or actuators, but I tried using it for heavier jobs and it struggled a bit. It’s a good size, well made, and perfect for small projects.
Jarrod Clubbe –
Been using this in a small robotics build, and it hasn’t let me down. Tested with different voltage, and it responds consistently. Great quality motor.👍
Robert Powell –
I created a device that needs gear motor, I bought the recommended motor but the sound is loud and the speed cannot reach my needs. I found that this motor was quieter and the speed was more satisfying to me when I tested it. Excellent product for my device!💛
