This strikes me as a brilliant business model with opportunities for smaller and larger chassis manufacturers alike.

Making the 4 wheel drive points modular is a nice touch.  If something goes wrong with one wheel or motor unit just replace it with a new or rebuilt one and send the old unit out to be rebuilt.

What was the other company with a very similar concept - small pickup, delivery van, camper van all built on the same skateboard platform?

Canoo?

Canoo’s electric microbus will start under $35,000 when it comes to market next year | TechCrunch
https://techcrunch.com/2021/05/17/canoos-electric-microbus-will-start-under-35000-when-it-comes-to-market-next-year/

"Canoo is taking a different route than many other electric vehicle manufacturers. The company’s trio of vehicles all have the same proprietary “skateboard” platform architecture that houses the batteries and electric drivetrain in a chassis that sits under the vehicle’s cabin."

Debbie likes in-wheel motors. Belly-up-ish Lordstown Motors was going to use them.  From what I saw earlier, IWMs didn't seem as efficient, but that may very well be wrong.

Lordstown Motors Signs Licensing Deal With Elaphe Propulsion Technologies for In-Wheel Motors for its Electric Endurance Pickup

https://www.futurecar.com/3925/Lordstown-Motors-Signs-Licensing-Deal-With-Elaphe-Propulsion-Technologies-for-In-Wheel-Motors-for-its-Electric-Endurance-Pickup

"The L-1500 in-wheel electric motor is the most powerful compact in-wheel motor ever produced, according to Elaphe. Each 370 volt electric motor produces a continuous torque of 650 Nm (480 ft lbs), with a peak power output of 110 kW (~150 horsepower), without using any gears. The L1500 in-wheel motor is compatible with all drive layouts, such as rear wheel drive, front wheel drive and four-wheel drive vehicles.

Elaphe's in-wheel motor also includes an integrated standard disc brake, a standard outer caliper and a standard hub bearing."

They can't be too ineffecient, at least not if well-optimized, since that is basically how railroads run. The diesel engine turns a shaft that drives a generator that sends electricity to the traction motors that, yes, are next to, not in the wheels, but still the same idea isn't it?

If Elaphe would develop a kit that included a controller and a battery (or recommended battery), this would be a great conversion set-up.  We could start with Travoli's SUV.

Canoo is also belly-up-ish now.

I'm still rooting for Canoo

Quote
Canoo plans to build the Lifestyle Vehicle (which will be available in both passenger and cargo trims) at a new plant it will build in Oklahoma city. It will complete the plant and begin manufacturing vehicles in 2023 and actually shipping them to customers next year when it plans to ramp up production to ramp up production to 20,000 units; it wants to build 70,000 vehicles annually by 2025

I don't know. I hear they were putting out an RFP for selling advertising space on helmets
