Fun thread, here is my two cents, I'll mix in some plausible and never gonna happen ideas. My experience is with a 2020 Levo Comp
Stronger belt. I have had no issues, but it seems to me they are overdriving the brose motor compared to what it was designed for and belt failures may be the result. They need to just overbuild that a bit and put that to rest so people can drop their thousands of dollars and not worry if they will make it through the summer.
Whatever electronic upgrades they need to get fast enough sampling that riders don't notice the motor pushing after they have stopped. This probably means they need to get it down to 50-100ms of overrun. I mean actual 50-100ms, not like the 200ms that Specialized quotes now when sometimes it keeps pushing for multiple seconds after I stop pedaling.
Wireless or internally routed (di2 style) remote. We all like clean cabling.
Quieter. Your average person you run into on the trail woudn't even know we are on electric bikes if they didn't hear us given how subtle some of the designs are these days, but you sure hear them. This is a very predictable frequency noise, I would think a sharp engineer could put a small speaker in the motor housing pumping out the correct sound to cancel out the noise fairly easily with a small low-power speaker, bose noise canceling headphone style.
Less drag. I tend to turn off my motor when I pass people, even though e-bikes are allowed in my area, I know many people are out there to enjoy peace and quiet so I like to give it to them, but pedaling sure is hard once the motor is shut off. I noticed on my bike stand today just turning the cranks with no chain on has a considerable amount of resistance/gummy feeling.
As mentioned before, let me buy a frame for a reasonable price. Few of us like the groupsets offered by manufacturers, why not let us just buy what we want? A Levo Comp is 6k USD, a S-Works frame by itself is 6k USD. Why not offer the Aluminum frame for 4k? I would have taken that in a heartbeat, as it is I bought the comp as the cheapest way to get an Aluminum fame and 700wh battery, and will proceed to replace nearly every component on the bike. I would have preferred a frame, but if it's the same price either way I might as well have some spare parts I guess.
Centrally mounted derailleur similar to what Honda did with their old DH bike. I have no interest in something like a Rohloff, I've had one before and I can't think of any areas they beat a centrally mounted casette/derailleur these days. Having to shut-off power to shift is just terrible for climbs, they are heavy, and draggy to pedal. Yeah, you can shift without pedaling, but I'm much more interested in being able to shift while pedaling. And with a motor and central mounting, if you really wanted the shift without pedaling someone could work up a way to spin the internal cassette when you shifted even if you didn't pedal.
That's all I have, overall I'm quite pleased with the current offerings so with exception of the centrally mounted cassette, it's all pretty minor tweaks to the current formula which I think is a pretty great place to be.
bad thing I will miss fun riding now one...but thinking to go in demo days if it will be possible this year ...
