.......... i have no trouble with Majors remark but guys he made a good point there your grumbling keeps positive people out of this forum and it is not good for the project.
so, could you cheer up just a little?
I try to grumble in a cheerful manner My intent is to turn those positive people into realistic people. Time spent pursuing wheelmotors is wasted and non productive in regards to the do-it-yourself electric car conversion process.
Mr. WheelMotor (the OP) is different. His intent is to become a vendor of wheelmotors, not a do-it-himself converter. I actually think my comments can be helpful to him, even though those comments are negative concerning the product and application. Maybe I give him incentive to prove me wrong Or point out a horrendous design, although it appears he can recognize such when he sees it.

Reason: grammer
Ok ...
So, even on a DIY EV forum, except one, nobody want to spend realistic money to make his car hybrid ...
The poll is a sad confirmation.
Not prepared to give simply up yet !
I will stop this thread probably and join or start an other non commercial one in this forum. If the WM approach has to many weaknesses, lets start again.
I want to make my car hybrid !
We need a solution that is:
Cheap
Retrofitable (without using a grinder )
Over the counter parts
Performing
Hey Seniors, is there already a thread in the sort of: "let's make a normal car hybrid" in this forum? (with adding parts only, letting the car intact as it is)

It is simply not economically or even environmentally reasonable to spend $10,000 or more to get a few percent better fuel economy and a few other benefits. I can purchase a car like my Saturn SL1 for well under $2000 and get 35 MPG average and 45-50 MPG on the highway. Even at $5/gallon I'd spend about $1500 to drive 10,000 miles or $0.15/mile and even a 100% plug-in electric still costs about $0.04/mile just for the juice, but the batteries will cost $0.10/mile.
I'd be very interested in a bolt-on wheelmotor system for about $2500 that would mostly benefit stop/go driving and would provide 4WD and emergency alternate propulsion. Maybe you should start another thread under that more realistic premise and take a poll and start working out the technical details.

I don't know of such a thread. There have been maybe a couple along those lines, but they are long dead. One was using a Warp9 motor in the driveshaft of a rear wheel drive SUV.
I guess I didn't realize your motive was hybridization until now.
FWIW, and it ain't much, check this out.
Not quite as good as the MTSU motor, but similar. I have seen some other attempts connecting to the outside of the rear wheel, or adding a 5th wheel or a pusher trailer or a propeller. Nothing I consider worthwhile by a long shot.
There was a British company which a few years ago had a system which attached to front of the engine via a belt drive. They claimed impressive results and fairly low cost. You know me, I was skeptical of it. Appears like they dropped off the face of the earth.
I also met a fellow with a hydraulic system putting motors on the half shafts. He was developed to the point of prototyping. That was about 5 years ago. Lost track of him too.
About the only approach I see having true potential is tapping into the driveshaft on rear wheel drive vehicles, and that isn't what you're after. You know how to pick the easy projects

You do understand that this is a DIY ELECTRIC car site, not a hybrid car site. The idea for most of us is to eliminate the ICE. Spending almost as much as doing a full EV conversion but ending up with something less desirable to most of us is not exactly a recipe for success. The fact is if you want a good hybrid in a similar price range you can buy a used one.
I like my Jaguar. I can't afford the newest Hybrid Lexus, Merc, BMW etc.
If I could drive 100 miles with my car electric for a conversion cost of about 6000 Euro and if it would be legaly allowed in Belgium, than I would go imediatly 100% electric. But Hybrid is the next best thing. If I could do 10 miles around town pure electric and for the rest Parallel Hybrid for about 4000 euro : that would a be an excellent compromise. This is a subject for an EV forum, because the E-range will depend on the cash you can afford for the batteries. I will start a thread to brainstorm open about that. Not with the ambition to sell a set, just to have input and show my progression so that others can dream along.
As long as you understand that most of the audience here doesn't have the same desires as you do, they are interested in EV's, which, not surprisingly, your poll reflects.
I like the idea of the trailer hitch pusher attachment. But I think it would be best to have the wheels mounted on a lever and pushed under the vehicle in line with the existing rear wheels, which eliminates the steering problems and also the safety and visual aspects of what is essentially a trailer.
It could be used as an emergency device, stored in the trunk and just slipped into the hitch receiver when needed. It could be designed only as a low speed high torque device that could push the vehicle to a place of safety. Or it could be mounted on a hydraulic or electromechanical arm which would contact the road surface when the speed drops below, say, 20 MPH. For maximum traction, or as an option in case of a rear wheel blowout, it could be made strong enough to lift the entire rear of the car. It would then become essentially a tricycle, with associated handling issues, but the existing rear wheels would be only a few inches off the pavement and would act as "training wheels".
I'd be very interested in such a device. A conceptual prototype could be constructed for under $1000, and it would be easily adapted to any vehicle with a hitch receiver. I like it!
Re: In Wheel Motor ... affordable

Mindless happy cheer leading gets you no where.
In Wheel Motor ...conclusion: unaffordable !
