I’m not even sure I fully understand the concept. The idea is that you ride the bike gathering energy into the solar panels and wheels (somehow) and that charges a battery? That bike alone would have to weigh at least at least 90 pounds or so. I have a 1965 Schwinn American and it kind of sucks riding it more than say ten miles or so and it weighs maybe a third or what that bike would weigh in at. I’m all about innovation of course but I don’t see it happening.
