Very cool concept. It’d be helpful if there was videos of it working or some details on the process you made to build it. Or even why you did.

The home page is a video of it working. Including throwing gasoline on it when it's already on fire. While it's running.

  The practical demonstration in the video are fun and memorable. Realistically I'd take a lighter case without ability to submerge the whole thing in mud and set fire to it, but I'm in urban UK. It seems to be built for a warzone, milled out of solid aluminium?

    Or built for a place with only dirt roads, heavy muds during a rainy season, probably very limited ability to get spare parts, and a desire to use it for years after buying it.

      I'd have thought reducing weight would provide more utility (in rural monsoon areas, say) if violent contact wasn't part of the problem - it might survive crashes that destroy the bike, maybe that's the design decision. FWIW, I'm not saying it's wrong, just notable in the apparent robustness.

  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.

      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). https://en.wikipedia.org/wiki/Crore https://en.wikipedia.org/wiki/Crore , https://en.wikipedia.org/wiki/Lakh https://en.wikipedia.org/wiki/Lakh

totally missed it at first but just watched it. badass. Inventions that build upon what is already in the market are the most ingenious
