I test rode a 2018 Zero SR 14.4 kWh bike today. Wow! I am impressed! I have never ridden an electric bike before, so wasn’t sure what to expect. The Zero has an “eco” mode, and “sport” mode. There is also a “custom” mode, but it had not been programed yet on this bike. I rode about 35 miles, some in stop and go traffic, some highway, and a little 2 lane road with curves. I started out in eco mode. It is very smooth starting from a stop and the response to throttle is very good and easily controllable. The eco mode has some regenerative braking, but the engine braking was way less than on my Moto Guzzi V7. I think the custom mode would allow for more aggressive regenerative braking. Acceleration in eco mode feels very linear, and seems a good deal faster than my V7. The sport mode is a hoot! It is still easy to modulate at slow speeds, but has a real rush of acceleration with not a lot of throttle twist. It’s very easy to be going 80 mph plus before you even think about it. And absolutely no vibration. The absence of engine noise is really nice, and this is coming from a guy who has ridden ICE bikes for around 45 years. It sounds like a jet engine spooling up, but is not loud at all. My left hand reached for a non existent clutch lever only once at a red light. Just twisting the throttle and going without shifting feels very natural. I wasn’t sure how I would like it since I have never ridden a bike with no clutch and shift levers. I could get used to this! The range with the 14.4 kWh battery is supposed to be a minimum of 100 miles even with aggressive riding. Based on the battery meter readout in the 35 miles I rode, I think that is probably realistic. Ridden the way I normally ride my V7, I suspect I would get close to 150 miles. I didn’t expect to like it as much as I do. They are expensive, but I am seriously considering trading my V7 for one.
