Would you buy a Ferrari with an automatic transmission (not sure if they even make such a thing because sports car drivers want gear control ... not some program guessing what gear they want to be in).My first ebike was throttle only. I still have it actually. When I got a PAS bike it worked like any bike. When you want to go faster you pedal faster, when you want to go slower you pedal slower. It's intuitive. One does it without thinking. "It's just like riding a bike"
I'm also a motorcycle rider, I'm not against any of it. A throttle on an ebike is manual pedal assist, PAS is automatic pedal assist. I'll never go back.
A buddy of mine, a fellow ebiker, has a throttle only bike. For the longest time he didn't understand what was so great about PAS. I tried to explain the difference it makes in everyday riding. With throttle it requires constant adjustment to match your cadence for a desired speed. The one hand remains glued to the handlebar. Don't move it, don't relax or your speed will change. My buddy now has a PAS bike and loves it! When he uses the throttle bike, he finds it annoying, a distraction to the cycling experience. That's particularly true for long rides.
On my current motorcycle I have electronic cruise control. Speed automatically adjusts. Best thing ever added to a motorcycle. Cause you can't have PAS
I had stick shifts in cars and pickup trucks for decades. That got really old when I had to do a lot of stop and go driving. Constant work to maintain the desired speed. I now drive an automatic pickup. Same with throttle versus PAS. I'm enjoying the ride!
Also there are some new ebike Throttle controllers implementing both assist level and speed-hold cruise controls (they just don't have torque, cadence, speed, gear, and now the new Yamaha motors have angle detection inputs to a program to determine assist levels).
