Justin from San Francisco. Just bought a 2017 Zero SR w/ 2.5 kW charge tank from someone in Santa Cruz (Electric Terry happened to be passing by just before the test ride and I got to meet him and Charger). I got into riding motorcycles a couple years ago and worked for Scoot for 2 years and rode their electric mopeds since 2015.
I always wanted an electric motorcycle and only bought gas bikes because I couldn't afford one (until now). Now that I have the Zero, I doubt I will ever own another gas vehicle, even if it will be hard to give up the seating comfort and riding position of my 2011 Ducati Multistrada.
Biggest bright spot about the Zero is the total lack of drama. No need to ever worry about being in the wrong gear, stalling the motor when braking, left hand going numb feathering the clutch for lane splitting episodes that drag on and on and on, etc. Biggest complains are the acute knee angle, lack of legroom, and seat comfort in that order.
I just bought an Airhawk pillion pad to improve seat and knee comfort and increase legroom, and will try fitting SR/S footpegs. I'm also planning to add a USB socket based on Alternative Standard's YouTube video (but using one with a USB-A and USB-C jack), get a bigger windscreen than the current commuter screen (I'm thinking CalSci), install my Atlas throttle lock, some axle sliders front and rear, maybe get some wheel covers, and upgrade the charging with a DigiNow setup.
I'll mostly be using it for <100 mile trips around the Bay Area with the occasional 150 mile jaunt.
