Excellent value

For less than 10 € this gearbox is perfect. Offering a choice of 167 rpm for 0.2 N.m. OR 47 rpm for 0.71 N.m. Excellent product for low-cost model making

Works Great

Works great for our Rover. Bought extra as a backup just in case something went wrong before the tech fair. So far so good!

RobotShop delivers again

I knew and own this product before but needed another and wanted to test first and good experience with RobotShop again and they delivered. Price is about the same as a well known online seller of everything but they are not in the motor gearbox business so I'm happy to see I've found my new supplier in RobotShop.


This was good for my needs. Yes, the gears are plastic and the motor is cheap, so if you're looking for durable motors that need to operate at high torque, find something else. However, this was perfect for my needs in constructing a path finding bot.

Perfect for a quick build

Bolted to a piece of acrylic with a nylon bolt skid. I had to play with the balance because the motors are quite far back from the axle, especially in "high" speed configuration, causing too much friction on the skid. One motor gear has a split making that side a bit noisy. Driven by a DRV8833 with a single 3.7 V Lipo. Would like to try with the "sport" wheels
