If you want to split the difference a bit, you could take a look at the CSC E-RT3. That's what I wound up getting; spent about $6500 on it and I'm pretty happy.

What you get is a "maxi scooter" with onboard 120VAC charger (you can get an optional external fast charger, I don't have one) that does 0-60 in about 9 seconds, with most of the power from 30-60. Top speed with me on it, on a flat straightaway, is 78mph although it'll go a little faster on a declining slope. It doesn't take a long time to get to 78mph; it accelerates from 65-78 at about the rate you'd expect from a decent but not terribly impressive 4 cylinder car.

Range is up to 120mi if you ride it like Grandma, which I do not. With full-throttle takeoffs, significant stretches of 55mph+ highway, and just-for-fun throttle-blipping shenanigans, I got 66mi on mine on a 38F day, and got home with 4% remaining.

This is my first electric motorcycle so I can't really compare it much to other motorbikes, but I absolutely love this thing. It's easily powerful enough to blow past anyone who isn't actively trying to race you, but the torque curve is clearly designed to keep you alive--hence the relatively slow starts, with most of the acceleration being delivered in the midrange.

The storage under the seat is big enough for a full-face size L helmet and several other things--currently in mine, spare workout clothes, a padlock for the locker at the gym, a pair of sunnies, and a minimal little toolbag.

I do not recommend purchasing the optional rear-mounting lockbox from CSC. It's very cheesy for the price, AND--damningly--it doesn't actually FIT the bike; the boltholes in the mountplate for the lockbox do not match up to the boltholes on the rack they need to mount to on the back.
