I've watched many Aptera video and today again saw the interview with Chris Anthony where he claims the Aptera is more efficient than a bicycle. I wonder what is the basis of such a claim? Seems ridiculous to me.

Aptera plans to be global based on everything I've heard and read from their founders. In the years I've followed TWIKE they have never made global distribution a goal.
Here is the link in English. I only found a representation in London. From the data it should be no problem for USA. But the same procedure as Aptera. In August I will test drive it, as far as corona allows it.
TWIKE has been available in Europe for about a decade or more. I don’t think they have any plans or desire to market in USA. I remember there were a few individuals in USA that tried to establish distribution here but it never became real.
@boxster1971 Plus I'm pretty sure that the four wheeled version will not be legal here in the USA. It will not be considered a bike/motorized bike/motorcycle.
I actually meant more like this. Velocycles or Velomobiles have been around for competitive high speed record setting for a while. Most solar racing cycles and cars share similar aerodynamics.
@boxster1971You need both. First an e-bike to pass the time until the Aptera is delivered. Then, when you have an Aptera, you need a folding-bike that you can load into your Aptera for excursions into the countryside.
I think a human is significantly more efficient than this riding a bicycle.
An average resting human uses around 120 watts or so I think. A couple hundred more during strenuous exercise. 10MPH is not very strenuous so per mile the human is way more efficient. 6 minutes of maybe 150 watts above resting to go 1 mile. Equates to.... 15 watt hours per mile? 25 watt-hours per mile including energy the human uses to stay alive? Rough napkin math!!!!!!!
The similarities of Aptera and Twike. Aptera is only for the US market and Twike is only for the Europe market. 😥

This will be the alternative if we do not get an Aptera.

Just look up Velocycles and one can see how much aerodynamics play in the design of a bicycle.
Aptera much more efficient, say @>30mph than a person on a bike is my hunch.
BTW, refreshed MS is now down to 0.205ish coefficient!

But this isn't totally fair because the Aptera would be more efficient at these lower speeds than performing the EPA testing..
They claim efficiency of 100 watt hours per mile.
