> It’d be helpful if there was videos of it working

It was easy to miss, but the first image on the page is actually a fairly detailed video showing it working. Here's a direct link to the video.

This is a simple yet slick video! It clearly highlights the benefits of this invention. It was interesting to see the use of the uncommon word "inlet" (2m05s), which is the correct word for a socket on a power sink that accepts a power cable.

On the other hand, I didn't like the non-standard use of metric units: At 0m34s, "25 KPH" should be "25 km/h" (k is not allowed as an abbreviation of km, and p cannot stand for per). At 0m38s, "170KG" should be "170 kg" (metric is case-sensitive). At 0m43s, "40 KMS" should be "40 km" because plural symbols are not allowed (and can be confused for the second, e.g. N⋅s is newton-second and not "newtons").

At 2m20s, the claim "20mins pedalling charges 50% battery" sounds too good to be true. For example, 20 minutes of vigorous pedaling on a manual bike will not let you travel a distance of 20 km (half of the claimed battery range).

At 2m29s, "8 crore bicycles & rickshaws running across India", meaning 80 million, seems like a very small number for a population of 1.4 billion.

That's a new word for me (en-gb native). I assumed it meant something like '8 brands of...'. Thanks for clarifying.

Yeah, I had to research "crore" today due to the word being mentioned. Another Indian number word is lakh = 100,000, which I only knew since a few years ago (living in Canada for 30 years).
