I found this in my CroBorg thread (page 6) from April 26, 2012:
... I took a test ride yesterday of the Zero 2012 dual-sport. So now I've test ridden both Stevil's HT powered race-winning Greyborg and the Zero.
One interesting thing about the Zero. When I was first getting into ebikes and reading about the Zero the wife indicated she would rather I got an emotorcycle like the Zero than an ebike. Her reasoning was that the emoto could compete better with traffic and be safer. I had ridden a 500cc motorcycle for years without problems but haven't had a motorcycle for a long time.
It is interesting to compare them. For me there are two use cases they would both be used for. One is commuting to work, 13 miles, half 50mph limit highway along the lake and half windy hilly through the park 25mph limit. Actual speeds tend to run higher, of course. The other is dirt, camping, desert type uses which I won't cover here since I haven't tested either in that mode.
This was a brief test ride at work where the streets are narrow and pretty steep (7%) and the speed limit low. The seat on the dual-sport Zero is pretty high, but not a problem for me to straddle. It feels good, but on this short ride I won't be on it long enough to gauge its longterm comfort. The pegs are lightweight but effective which is the theme on the whole machine - they are working hard to keep the machine's weight down so they can save the weight budget for the battery. As you stand up the bike you feel the weight. Substantial, but less than my former motorcycle, a 500 cc water cooled shaft drive v-twin.
The kickstand is substantial but light, and easy to reach. It has a switch that interlocks the motor, so you can't power off until it is up, a nice safety feature. The throttle and front brake are on the right, on the left grip there is no clutch lever. The rear brake is on the right toe, the usual configuration for a USA motorcycle, aside from the missing clutch. The kill switch is on the right thumb, very similar to one I bought on ebay for my ebike. The dual mirrors are somewhat small and angular, probably designed to minimize air resistance while providing useful coverage. They seem to provide a useful view though not an expansive one. Having dual mirrors is nice, I've been doing single mirrors on my ebikes and I occasionally look for the missing right side mirror reflexively.
Flip the key on, the LCD speedo comes to life. Set the SPORT/ECO switch in ECO, make sure the kill switch is off. I'm starting on a gradient so holding the rear brake and rolling the throttle gently on, hear/feel some motor power pulses and release the brake, it rolls backward a bit. Quite a bit more throttle is required to get moving forward, and it takes off at a crawl. Incredible low speed low power control. You can easily ride at very low speed.
I did a loop around the hilly streets, gliding along and hitting the throttle progressively harder to see what it would do. No surprises. Good power, accelerates smoothly up hills. Competent. With my recent ebike experience I know they are managing this motor to keep it safe, cool and efficient, not pouring excess power into it. It feels like a good solid machine, not a thrill generating rocket. I flip the ECO switch to SPORT and test again. More powerful, still not a rocket. Feels good. Excellent brakes and throttle control. It is so easy to ride at near zero speed I almost forget to put my foot down at a stopsign. The extra high and forward weight of the battery makes this bike very easy to balance.
The turn signal control is spring loaded, so you can't leave it locked on, but the blinkers continue after it returns to center. I suspect it will time out, or you can cancel it by pushing it inward. Nice to have a turn signal, hand signalling on bikes creates some risks of its own. Turn signals on ebikes is a whole discussion of its own. But it feels good to have it, easy to use, and safe. I need to think about that more on my ebikes.
As I bring it back I need to turn it around on a gradient in the parking lot. The weight is noticeable, and the restricted steering angle. Much harder to maneuver around than an ebike which will turn much sharper plus you can always lift an end or even stand it on one wheel.
As I think back about the ride I realize I didn't notice the suspension. This is good, it works well, nothing to complain about.
So ebike vs Greyborg for my commute - how would that compare? The highway part of my commute is 50 mph with a wide shoulder, so with the emotorcycle (em/c) I could stick with traffic speed and save some time. Until it stacks up from too many cars. Then it is hard to stay legal and thread through it on the em/c. I see motorcycles threading into the bike lane, not supposed to do that, but they occasionally do.
On this part of the route the ebike has a pretty nice (most of the way) wide lane to itself. Not as clean, not always clear (disabled vehicles and clutter end up in the bike lane). So you can move along at bike speeds while the cars whiz by (watch them carefully though, some wander into the bike lane). Running high speeds in the bike lane is not a great idea, it just isn't that clutter-free. If the ebike will do 55 mph one could merge into the car lane, and that would be safer, but not really legal. My Greyborg is not being set up for 55, though it is possible to do that with over 100 volts.
When the cars stack up sliding alongside them in the bike lane at 20 mph is nice. It can save more time than was lost earlier if the stack is very deep. Then I peel off and turn into the hills, winding and climbing. The speed limit is 25, there are lots of corners, and the pavement is not good nor the roads wide. Here the Zero would be in its element, fun, perfect. Easily able to slide past the lycras which the cars have trouble passing. Possible to pass the slow cars safely. Fun. The ebike is not bad, a strong one like the Greyborg will keep speed equal to most cars, so the danger of getting passed would be minimized. Both Zero and Greyborg are excellent for this part of the trip, but Zero would be a bit faster.
Arriving at work the Zero would have to be parked outside. Finding a place with a power outlet to charge from would be a challenge. I might be able to get an extension cord or outlet positioned to use. Hard to predict. The Borg can be brought into my office. Out of the weather, away from prying eyes and fingers, and charging is no problem. Bringing a heavy ebike in up a few stairs and in the door is a bit of a challenge, but not hard. Make sure those lipos don't flare up indoors.
Taking the bikes places is also quite different. The em/c would require a trailer. I have one, but it is a hassle to load, unload and park with it. The bike rack is a lot easier to deal with. Hopefully my bike rack will be up to the Borg's weight, being a bit more than the usual bike.
It was a fun test ride, and I'd like to have a Zero. Someday perhaps I will get one. Thanks for the test ride, Dean of Pleasanton Mastercraft!
