Can anybody help me identify motors like these?

[mfgarris]

I want to build this easy PVC kart with my 7 year old son. The motors used are linked to an international site, and I'd like to find an equivalent that I can order in the US.

The specs he gives, from this site.

18V DC Mega Torque Geared Motor
Speed: 300 RPM, Watt: 250W, Torque: 92 kgcm

The link to his video.

Thanks. You all seem like experts here. I just want to do something simple and this seems to be the ticket. If anybody could point me in the right direction I'd appreciate it. I've spend a couple hours searching.

Howdy,

PVC?
...low cost learning project
...just make sure jr. wears some safety equipment

The motor you link to is for robotics (kinda small to move a person, even a little person)

Here is a kit (in the USA) for an actual scooter/small kart motor (~$75.00) delivered
https://www.ebay.com/itm/250-W-24-V...235579?hash=item237f56933b:g:bs0AAOSwsTdaoVjp

It comes with a 24V 250W motor, matching speed controller, twist throttle, On/Off key switch & even a 24V battery charger

...or this one comes even with batteries & has a battery indicator on the grip (~$100.00)

You don't need a geared motor, the motor sprocket (size), compared to your axle sprocket (size) will accomplish that for you
…& you can make adjustments (as needed, to suit your needs) as jr. grows

This motor is rated @ 2,750 (max) RPM's

So, if you use a 10 tooth (drive) sprocket on the motor
...& a 60 tooth (driven) sprocket on the axle
...you'll have a 6:1 gear ratio (2,750/6 = 458)
...which will bring your axle speed to ~450 (max) RPM's

If you use a 10 tooth drive sprocket
& a 72 tooth driven sprocket
...you'll have a 7.2:1 gear ratio (2,750/7.2 = 381.9)
...which will bring your axle speed to ~380 (max) RPM's
