I did. First is still the same 150cc replacement since the niche is sooo big. Even if you cost as much as best 150cc on the market, somebody will still buy it for electric convenience, so load it up with cheap fancy features too like cruise control, seat heater etc. A good 150cc has around 7-8kw of power, and it is the upper limit of a hub motor, and passive cooling, which you should capitalise on. 4.5kwh battery for 50-60km range. 6kwh premium option for around 80km. Air cooled motor controller for a completely liquid free design. Screechingly, you can fit into $5000-6000 premium 150cc segment.
