I want it to be capable to handle (move), a car/passengers @ +/- 600 lbs. at a speed up to 20 mph.I suggest going with a mid drive Bafang motor at 48 volts. LOTS of power
I have a cyclone 500 watt 24 volt motor I can remove from my unused hot rod. It has a reduction gear box. Worked rather well but not a whole lot of zip.
REALLY ! .. Most people have guard dogs. Brad has guard, ... 'BEARS'You may need to hop over Brad's fence to get a drive unit with enough torque. He is all for DIY so he may not mind.
Coaxial cable might be a suitable and far cheaper item that will pass for plug leads.
I have done as suggested, and used coaxial cable. I had a 100 foot piece left to me from a generous cable guy.some CAT5 computer cable would work and easier to bend tighter.
I like the sound effects.
Thanks for all the tips Brad. Will add to the 'much-to-learn' pile.Just crazy cool!
How about a standard PMDC motor and controller for the drive?
You could mount it any way you like, easy to conceal, and go fully belt for 100% silent operation.
It will run you a bit more $$$ than a hub motor, but will offer a lifetime of reliable service.
This one "Scott 1HP" motor as used on Sparky is still here ready to power one of my robot projects...

The controller is a bit overkill, 300 amp from a club car golf cart, but bullet proof. It is what I use on the Yard Mule as well.
This drive system is absolutely 100% silent.
If jogging speed is your max goal, a single gearmotor from an old powerchair would also work well.
Another 100% silent motor that will run for decades and can be easily hidden.
Here is one I was using as a drive and generator on a proto camper trike frame...

Power chair motors put out between 300 and 500 watts, and with the gearbox have torque rated in foot pounds.
Usually the output shaft is 3/4" and turning at 250-350 RPM.
Oh, and feel free to climb my fence, but beware, it is electric!
Thanks BradGreat build, all of it!
It really depends on how fast you intend to go and on what type of grade.
1000 watts can easily move a bicycle and an adult up to 30Mph+ on the flats.
Geared down to 15Mph, 500 watts would easily do it.
I have a 30:1 gear reduction on my Yard Mule, and when pulling only 3000 watts (4Hp), it will drag a large ATV even when the ATV is trying to pull me!
That motor would certainly have the power to move your vehicle at a brisk jogging pace if that's what you are after.
One thing to note is that it will be somewhat loud. Not as loud as a drill running, but similar sounding gear noises.
Mobility scooters tend to whine, so do rear hub e-Bike motors - or at least those I have been exposed to. Regen braking ones probably will too. The Bafang BB01 mid-drive that I have on my Warrior doesn't. I expect it is a 3-phase, brushless DC drive. Brushes will be the main cause of whine in a DC motor.I have watched some YouTube vids, of motorized vehicles, and they too had that annoying 'whinning' sound.
Thanks KevinHow fast do you want it to go?
Why the low opinion about the 48 volt?Pretty cheap would be Leary. Looks just like a cyclone 500 w motor but at 24v. The 48v IMO is a mistake or ??
Look a cyclone motors to compare. This is what I have on my "hot rod".
