Wind-up motors that pack a wallop.

These aren’t your normal pull-back motors. The first time you wind one up and release it, you’ll revel in the high torque, the long-distance runs, and the unexpected speed. They’re shockingly powerful.

Six Brute pull-back motors, each with its matching 16 mm front wheel-and-axle set

Brute 6-pack

$34.74($5.79 each)

Large size. Raw power. All muscle and no manners, with enough torque to make you wonder if your build is sturdy enough. This is the motor that started it all, packing such a wallop that I was inspired to launch Wallop Co.

You get six motors, as pictured. Each one has its rear wheels attached and comes with a matching front axle and wheels.

Six Stout pull-back motors, each with its matching 16 mm front wheel-and-axle set

Stout 6-pack

$23.34($3.89 each)

Standard size. Dependable strength. A workhorse the size of your typical windup motor, it’ll fit most things you build, with way more power and stamina than the motor it replaces.

You get six motors, as pictured. Each one has its rear wheels attached and comes with a matching front axle and wheels.

Six Ant pull-back motors, each with its matching 11 mm front wheel-and-axle set

Ant 6-pack

$16.74($2.79 each)

Tiny size. But mighty. A feisty little bugger that has no idea how small it is, and launches like it’s got something to prove. At 16.5 mm long it sits at 1/64 diecast scale.

You get six motors, as pictured. Each one has its rear wheels attached and comes with a matching front axle and wheels.

These go into 1/64 diecast customs, the bigger 1/32 castings, 3D printed chassis, custom toy designs, and STEM builds for the classroom.

We publish our motors’ dimensions so you can build precisely around them, like this 3D printed dragster.

The Ant and its front axle from above, beside a 1/64 diecast. That is the whole drivetrain, sized for exactly this.

The Ant under a slim 1/64 diecast. Narrow enough for a body with almost no floor to give.

A Stout inside a 1/64 diecast, weighted with six tungsten pucks over the drive wheels. There is enough torque here to lurch like a true dragster.
A black 1/64 diecast wagon in profile with an Ant pull-back motor built inside it
Even the Ant has the torque for a heavier 1/64 casting like this Hot Wheels wagon. It will not lurch the way the Stout does, but it assertively picks up and leaves.

I needed pull-back motors. But I felt bad tearing apart old toys for them.

While designing 3D-printed vehicles for my kids, I went looking for pull-back motors. But no one in the United States seemed to sell them. So I ordered straight from the best manufacturer I could find. When they arrived, I was stunned. They had far more torque, distance, and speed than what comes inside a typical cheap toy.

I thought, “Other people would love building with these.” So I started Wallop Co. My mission is to get these motors into the hands of hobbyists looking to give their vehicles some major pull-back power.

Dimensions

We publish dimensions for every motor, to make life easier for the hobbyist who wants to 3D print, hot-glue cardboard, superglue balsa, or duct-tape a cereal box around a pull-back motor to create the ultimate racer.
