micromobility - Ebikes, scooters, longboards: Whatever floats your goat, this is micromobility
Ebikes, bicycles, scooters, skateboards, longboards, eboards, motorcycles, skates, unicycles: Whatever floats your goat, this is all things micromobility!
"Transportation using lightweight vehicles such as bicycles or scooters, especially electric ones that may be borrowed as part of a self-service rental program in which people rent vehicles for short-term use within a town or city.
micromobility is seen as a potential solution to moving people more efficiently around cities"

It's a little sad that we need to actually say this, but:
Don't be an asshole or you will be permanently banned.
Respectful debate is totally OK, criticizing a product is fine, but being verbally abusive will not be tolerated.
Focus on discussing the idea, not attacking the person.

The highway efficiency losses are due to the inefficiency of the electric motors running at the higher speeds.
No. It is aerodynamics vs weight balance. Low speed, weight matters a lot. High speed takes major power to overcome air resistance especially if geometry is like a Harley instead of a motosport race bike. Electric motors are most efficient at top RPMs.
That doesn't explain all the data. EVs would also show a much greater drop on highway range than they do.
Aerodynamics is at play, here. Motorcycles have a better frontal cross section than cars, but their drag coefficient is much worse.
Edit: also, the drop in efficency at high speed is small. Depends on the type of motor, but it's usually only a few percent:

Please show the drag coefficients being so much worse?
Every number I find is very similar if not better.

The best cars are around 0.2. EVs have been getting close to that because they get hit hard on highway range if they don't. ICE cars tend to be closer to 0.3.
