Yes but you will have to google for it. The CA government has a web site that lists all pending legislation routinely. It is not going to provide Cliff's Notes though. You will have to dig thru it or just become generally aware of the legislative climate by staying current with industry sources who produce content in the industry..
You have to read that section of the bill.
@Dewey linked it in Post 225.
312.5(a) establishes the hard top limit of 750w output so that wipes out most of the ebikes sold in CA and the USA.
312.5(d) lists what is NOT an electric bicycle
312.5(d)(2) closes its sentence with an 'or' that expressly cites and excludes any bicycle whose power exceeds 750w
And to reiterate: The layman generally does not understand that volts times amps equals watts, so almost much EVERY ebike has power that exceeds 750w. That is not a hot rodded ebike. They all do that. 750w was never a set peak maximum amount. By way of example an ebike with a 48v battery (extremely common) and a 13a peak controller (which is weaker than almost every ebike sold today by anyone) is legal. But one with a 14a controller is illegal. Typical mainstream ebike controllers even from the big name brands are in the 20-25a range.
The legislator who drafted the bill didn't understand these technical underpinnings when they decided to make 750w a hard limit. Only the federal CPSC-sourced limit did this by making 750w a grey area on purpose.
