In the immortally sage and oft overlooked words of Colin Chapman "Simplify then add lightness."
What's more efficient than walking?

Do I need 2 tons to relocate a 80kg payload (me)?
I'm building a car killer. In fairness my car's mostly dead from neglect anyway. I'd fix it except if I did that I'd probably keep driving it.
Besides bikes are better.
Here's one I built earlier.

Two motor upgrades, 7 tyres (5 rear 2 front), two wheel hub rebuilds, one groupset, several drivetrains and 5500km later she's evolved to this.

2.25kWh, 2 horse power, and a throttle only range of 80km at 45kmph. If I quoted pedal assist it'd be inifinte for obvious reasons.
You can't buy an eMTB this capable.
Latest project is a cargo. It's stripped down at the moment.

...any wifey is away so bikes in the kitchen are kosher.
I spent yesterday building a towbar from an old quick release axle..

I thought it'd be cool to pull her own support vehicle. ..err...yeah....that needs a MKII the centre of gravity on the 25kg "trailer" is too high and unstable.
I've a kiddy seat and a roll-cage for the front.
Also a 3.5kVA case-mount

..and an induction hob..because I like vehicles than make coffee and bacon butties
Plan is fit a progammable mid-drive motor with 160Nm of torque.
Upgrade the groupset.
Bigger tyres for suspension.
Suspension saddle.
Suspension seatpost.
Integrated lighting kit with indicators and stop lamp on manual and light sensing controls.
Dual batteries: 52V 2kWh (combined): which can be plugged into the MPPT solar controller on the genset for more genset capacity or the genset can charge the bike on the fly for extended range, and I can enable VTG if I synchronise the genset to another microgrid or utility network and enable backfeeding allowing both the genset and/or the bike battery to contribute power to the network or micro-grid.
Third battery e-bike integration facility.
Spare tubes + toolkit.
First aid kit.
