I took my first ride today, and it went very well. I had used the Zero app to set the Custom mode as follows: top speed 80MPH, maximum torque: 75%, throttle off regen: 6%, braking regen: 100%.
I started the ride in Eco mode, and man, this isn't your Dad's Eco mode! Aside from a very soft start, useful for loose dirt and most city riding, the bike still accelerates harder than any electric bike I've ridden, and about as hard as my Leaf at low speeds - harder at higher speeds. Needless to say, there is just no comparison with the ZEV 5000, even with the Zero in Eco and the ZEV in, er, "3." I did about 20 miles of country highways in Eco, then on the beginning of the last leg of my 32 mile ride I switched to Custom.
Wheee!!! I've only ridden one or two ICE bikes that would leap forward like that when the throttle is opened at 60MPH, and they had roughly 100HP. I didn't run it all the way to 80 (it was mild but not warm outside, and I'm now old and feeble) but the bike seemed happy to just keep accelerating hard past 75MPH. Those Custom settings seem like the perfect "Sport" mode for public roads, with the actual "Sport" mode (which I didn't use, as I promised myself) best reserved for Special Situations, just like Tesla's "Insane Mode."
Ergonomically, the SR isn't the best bike for me. I have trouble with pain in my arms and hands, and supporting my weight on the bars with my arms isn't fun. However, above 40MPH I noticed that the force of the wind on my body actually relieved the strain on my arms. Only going down hills at low speeds actually hurt much. I'm going to adjust the bars once more, so I'm as upright as possible. The seat is about what I expected: on my fairly short ride it was fine, but on a long ride my butt would be hurting without an extra cushion. Most of the controls work fine, but the turn signal which isn't auto-canceling (despite what one might expect on a $16000 bike) is easy to activate but hard to turn off - it wants to switch from signaling a turn in one direction right to signaling the other way, especially for a rider wearing gloves.
The suspension works very well to absorb harsh bumps and keep the tires planted on the road. Since I only ride fast on smooth roads, though, I'll likely adjust the damping toward softer, for a more comfortable ride over small imperfections in the road.
I started the ride with 100% charge, and a range estimate of 61 miles. I finished it, 32 miles, later with 65% charge and a range estimate of about 55 miles. I didn't reset the efficiency reading, but I think it resets for every ride, and mine was 94.5 watt-hours per mile at the end of my ride. This means that for my riding style and roads, I expect the warm weather range to be between 90 and 100 miles for me. I'm finally starting to believe that it's the 21st Century!
