Zero bikes are fantastic commuters, especially in areas with good charging station coverage.
There is also something to be said about the effortless availability of performance with the Zero's as well. As long as it is above 50% charge, not already in Thermal Protection mode and currently in Sport mode, a Zero bike is constantly ready to instantly provide 100% of its performance to even the most novice rider. Pin the throttle and off it goes.
That's not the case with most ICE bikes. The rider will have to have practiced quickly shifting into the right gear, knowing how to launch a bike well, not stalling, know when to best shift to the next gear, not miss a shift under stress, etc. Without those abilities, the ICE rider will never tap into the full performance potential of the bike. A novice ICE rider could easily get outperformed by a slower Zero without all of those skills.
We saw it recently where a new rider on an SR/F beat a Ducati in a drag race. With the right rider, that Ducati would have likely killed the SR/F, but due to a stumble with the Ducati rider at the start, the new rider on the SR/F won the race.
