Hoping I can shed some light on why prices, speeds, and motors are what they are for electric. (I'm the main design engineer over at Spark Cycleworks). You'll see alot of folks limiting to 28mph: This is directly tied to the three different classes ebikes are being broken up into by law 28 is related to a class 3 ebike. Also mopeds can't legaly go faster than 30mph, so a manufacturer like us can't sell it. For motor: This is an evolving topic. We all know the 50 cc rule. Well, that's changing. For example, our shop is in Connecticut and the new rule adds a 2hp clause. That translates to 1,491 watts. Which is why our mopeds are 1500 watts. Above that and it becomes a motorcycle. We expect to see that law spread around the country. For prices: as you'd expect it's all the batteries and tariffs. From what we see, those prices are steadily declining. That 2k price point will be realistic in about a year. Although, 40+mph wont be unless you've got a motorcycle license (unless super capacitors and battery tech evolves).
