We just got my wife a Cannondale Synapse Neo 2 E-Bike that ‘does not’ meet all of your needs for $1,200 and change off from MTB Specialists while on vacation in Durango, CO. They were running a sale. They had a medium and a large. She got the medium. She loves it. I took it out for a long ride and I have to say, I could ride one of these too. It can easily go 20 mph with riders assist (Eco Mode) up to 100 miles but mileage in Tour, Sport, and Turbo modes. It is rider assist though. Not turn a throttle and go. If that is what you really want you may want to also consider electric motorcycles.
