After riding for 60 miles, some thoughts:
I see the CCS as an urban, utility flat bar road bike. With that in mind:
*Use a narrower handlebar to suit sporty urban riding - though evidently many people don't want this - I think this is best accomodated by creating another bike in the lineup for more casual riders (or beefing up the Air or Ocean)
*Allow the throttle to take the bike up to a user designated limit, <= 28 mph for class 3, when combined with pedaling. I looove the throttle for acceleration at lights and through turns to beat cars coming my way, but I often ride with low assist (Eco/1). Sometimes I get into a bit of traffic where I want high speed briefly, and don't want to fiddle with the assist level.
*Have a quick button press combination that can convert it between class 2 and class 3, to make it easier to stay at safe speeds in congested areas or bike paths where class 3 is illegal.
I would happily trade this for the Cruise Control, which I can't see a safe use for in any populated area. Cruise Control's originates in serene highway driving for hours between cities (and nowadays is semi-automated with detection of vehicles ahead, ACC).
*The times I've tried the Walk feature, it was too fast. Maybe it's for stairs?
*Sometimes I want to pedal softly, but not receive any assist, to get to a red light or whatever. Right now, I have to either coast or use assist. I'd like an option to set the threshold for when the assist kicks in, based on pedaling force I guess.
*Better bike security. Maybe making the bike inoperable without a key in it (certainly with the battery, and maybe even without the battery).
*Narrower cassette range (11-28?). I'll probably do this myself, but I find myself wanting smaller steps between the higher gears, and not using the lower gears much at all, even on low assist.
*Hex bolt for the seatpost, and hex front wheel skewer, not a quick release.
I also think there's room for a more premium bike, say $2000ish with 12.8 aH battery. Basically all the upgrades people here do on their own, or more polish:
*Like Ravi said, better groupset (Deore or SLX?), brakes, though I haven't had an issue with the latter.
*Color matched alloy fenders and rack (black or chrome)
*Rear wheel lock
*Bluetooth integration with phone would be cool, if you can get the software off the shelf at low unit costs (not commission it yourself).
*Optional Airzound horn
edit:
*Maybe a rigid carbon fork to cut weight?
*Add a no assist level, to save battery but keep the light on. Have a user option to automatically cut assist at 5-15% of battery capacity, to avoid battery damage and/or save the juice for the light(s), so you don't get stuck with an empty battery and no lights at night.
*Frames that vary by size in more than just the seatpost.
*In general, benchmark the bike against Stromer, Trek, Specialized (minus the mid drive motors if they cost a lot more) electric commuter bikes.
Edit 2:
When bike sales volume allows, create a more casual speed cruiser model so that the CCS can focus on sporty riding.
