It can get really confusing, and very seldom does any one place you look have all the information you need. You need to get your information from official state websites or publications. Looking at the wiki for California, it contains a very obvious mistake. Lots of misinformation on sites that try to summarize the laws for you.

The frame of an electric bike also has to be slightly different. The main part of the frame (the bit that supports your weight) is usually made from lightweight aluminum alloy: the lighter the frame, the lighter the weight of the bike overall, and the further it can travel before you need to recharge the batteries. The spokes on the wheel also have to be stronger than the thin spokes on a traditional bicycle. That’s because the electric motor in the hub spins the wheel with a lot of turning force (known as torque) and, if the spokes were ordinary lightweight ones, they could bend or buckle.

Please ride like a normal bike rider, not like a hooligan. Even if you left your hooligan days behind you 30 years ago, you never know, you could get into an accident. Or, your town might have one cop who just hates bicycle riders.  My town had one that lived for just one thing, ticketing bicycles going faster than 15 mph or passing a car in a school zone. You might not be able to talk yourself out of a ticket, but it sure helps to have some idea if you are really legal or not.

when the motor produces maximum continuous rated power of not more than 250 watts (n.b. the motor can produce more power for short periods, such as when the rider is struggling to get up a steep hill).

In the 1890s, electric bicycles were documented within various U.S. patents. For example, on 31 December 1895, Ogden Bolton Jr. was granted U.S. Patent 552,271 for a battery-powered bicycle with “6-pole brush-and-commutator direct current (DC) hub motor mounted in the rear wheel.” There were no gears and the motor could draw up to 100 amperes (A) from a 10-volt battery.[5]

Built with durable e-bike rated components, the Archer is ready for trails and pot-holes. The oversized axles and adjustable suspension provide a confident feel as you race down the trails or streets.  

We also crossed the 1kWh barrier by combining it with 21 Ah capacity. This is 95% more range than the standard e-bike battery. We added real-time GPS tracking and topped it off with a 8A fast charger capable of special programmable charging protocols that allow for over 1,500 recharge cycles to be extracted from your lithium battery.

“We want our bike to be a sexy product, one that everyone will want,” says Daniel Del Aguila, a co-founder of Prodeco Technologies, which is about to open a new factory near Fort Lauderdale. By squeezing efficiencies out of its supply chain, Prodeco sells a number of models for $1,000 to $1,500 that, Del Aguila contends, compare favorably to bikes selling for $2,000 or more.
