Maybe windshield wiper motors would do?
So I then tried Power Wheels type motors and they work fine. I bought 4 from www.resunltd4u.com.
Not sure why you had a problem with the link. Try getting there by googling Resources Un-Ltd. The part number is Product # CARDRIVE FP. You can also go to: www.modifiedpowerwheels.com There is lots of info there on how to work with these motors, and other sources for them. There are lots of different versions of this type of motor, but you shouldn't have to pay more than $15 for them. There is a different version of a kiddie car motor at Surplus Center. It looks smaller than the one I am using.
The motors work fine on my 4-wheel 35 lb vehicle with skid steering. The vehicle has 10 inch tires, which gives about 4 mph speed. There is plenty of torque. I am using one motor per wheel, but there is enough torque if you only use two motors with two powered wheels and two caster wheels. After all, these thing are designed to carry kids weighing a lot more. The vehicle runs in deep grass and up hills w no problem. I am not using an ESC, just on-off controls.
The design of these motors makes attaching to wheels easier, since it has a flange with it. The only problem I had was my wheel didn't have a good place to bolt the flange to, so I had to design a work-around.
You're going to need more than two wheels unless you're building a segway.

do you mean to control it manually via joint stick or it be autonomous?
