The Zero and me in City Bike magazine
« on: March 23, 2012, 03:01:02 AM »

Last month I got a call from the editor of the Bay Area's monthly free motorcycle magazine, City Bike, Gabe Ets-Hokin, who I had previously met at a BMW rally. He had discovered that I had recently bought a 2012 ZF9 Zero S. Gabe told me that they were planning on writing a feature article in their April issue on electric motorcycles, reviewing both the Brammo Enertia and the 2012 Zero DS and S. I was asked if I would like to join them as they were doing their photo shoot near Golden Gate Park, about 12 miles north of my home. Naturally I said sure, that sounds like fun and headed on down there.

The next thing I know, my red Zero (which looks better than the all black one) and I (with my day-glow jacket) are being photographed in black and white for the magazine. Then I was asked to write a sidebar to their 4-page article about living with the Zero from an owner's perspective.  The magazine just came out and (as their web site hasn't been updated with the new cover yet) I took a photo of the magazine cover which is attached.

Here is what I wrote for my sidebar. I might add that my services as a writer and as a model were just as expensive as the magazine.

Living with a Zero
by Richard Harmon

So what is it like living with a 2012 ZF9 Zero S?  Two words, cheap and easy - if you can get past the initial purchase price, of course. The Zero requires very little maintenance. You don't need to change oil or filters, maintain and clean a chain, replace sparkplugs, replace batteries, adjust valves, balance throttle bodies, adjust the clutch, or spend an hour removing bodywork to get to all that stuff.  That really cuts down on maintenance costs.

How about running expenses? The other day I rode the Zero from my home in Pacifica to the town of Fairfax to visit my daughter, a round trip of 76.8 miles. I adhered to the speed limit during my ride. About 10 miles of my travel was on the freeway and the rest was on surface streets. Using a Kill A Watt meter to measure the power consumption needed to recharge the battery pack, I used a total of 7.6 kWh of electricity for the trip. PG&E charges me 13.7 cents per kWh, so the round trip only cost $1.04, or about 1.35 cents per mile.  If I had ridden my Triumph, which gets 42 mpg, my fuel cost would have been $8.21, based upon the $4.49 a gallon price for gas at my local station that day.  A savings of $7.17 on just that one trip. When you add the lack of any substantial reoccurring maintenance costs and the likelihood that the motor and battery pack will outlast the chassis, it shouldn't take too long to recoup the greater purchase price of the Zero if you ride it a lot.

That is the cheap part.  But the bike is really easy to use. You just turn on the ignition key and then ride off. You no longer have to play with the choke and/or wait for the motor to warm up. What the Zero lacks in its ability to go long distances, it makes up with its ability to do all of those daily short trips (within a 40-mile radius) quickly and easily. And of course, commuting to work is where it excels. Plus, since the bike has no transmission or clutch, getting stuck in a traffic jam is a breeze. You can do the beep and creep very easily by just turning the throttle slightly to move at a walking pace, or you can ride between stopped cars as the bike is very narrow. No smoking clutch, overheating engine, or cramping left hand. And if the bike gets dirty it is very easy to clean since it has no exhaust system or chrome to polish.

You might ask if the lack of noise is a safety issue. So far it has not been for me.  No one has moved into my lane any more than usual and my only real concern is when riding around pedestrians or bicyclists. I tend to be very careful riding in an urban environment since the bike is so quiet.

Finally, there is the issue of reliability of a new product and customer service from a small start-up manufacturer. I had a minor issue with my bike twice stalling at stoplights. The staff at Zero heard about my complaint on the internet and called me to say that they would pick my bike up at my home, take it to the factory in Scotts Valley and return it to me with their latest programming and a new throttle assembly. They did as they promised and the bike has been running great ever since.

While an electric motorcycle may not be for everyone, it works for me.



The feature article itself is reasonably positive They pointed out that the 2009 Brammo Enertia and the 2012 Zero were not being compared against each other, but that is the way it came out.  In a nutshell, the Brammo has the better chassis accessories, such as brakes, suspension and build quality, while the Zero has much better performance and range due to its three-year technology gap.  Mention was made about the Zero's "no-name" suspension and brakes - which is not exactly true, as the suspension is made by Fast Ace and the brakes are made by Hayes. There were also comments about the inability of electric motorcycles to perform wheelies - which is something that I have no interest in doing. The article may not result in a stampede to purchase electric motorcycles, but it gets the idea across that they have arrived and are here to stay.

You definitely look very happy in that picture...
If you get an electronic copy would you mind send it to me? (we do not get this magazine in Spain)

I wish I could help you, Lipo323, but I don't think they produce an electronic copy of City Bike. At least I have never heard of one. But you might try to contact the editor at http://citybike.com/contact.html

The best I could do for you is to photograph the article and email it to you.  If you send me a PM with your email address I can take the photos and send them to you today. Most likely, anything readable would be too big a file for an attachment to this site (and might also be a copyright issue).

I noticed they have back issues available as a PDF download here:
http://citybike.com/back-issues.html#

Unfortunately the jan 2012 through mar 2012 issues are not available (yet?) in PDF. In the absence of other information, I would assume that's just a publication delay - maybe a couple of requests could get the april 2012 issue out earlier?

Very good article you wrote, Richard. While most people cannot get past the high initial cost, for a commuter the per mile cost over time will be cheaper than most motorcycles capable of going 80 mph, provided the motor and battery hold up as anticipated. It will be interesting to see how the Brammo Empulse performs. 100 mph seems optimistic. The Zero S vs. Empulse will be the comparison I want to see.

I photographed the four pages of the City Bike electric motorcycle article. They are readable with a little magnification. If anyone wants me to send them the photos of the article, send me a PM with your email address and I will ship them off to you.

I think they'll be able to blow past 100 mph pretty easily. If the Zero can do 88 with between 20-25 wheel horsepower (down from 29 peak hp, or about 40 claimed motor hp), then the Empulse should be able to put down 40+ hp at that speed by virtue of being able to shift into its peak power band.

I shudder to think of range at 100 mph. But that speed should be a shoo-in if IET is reasonably efficient and they meet their power goals.

I don't think the Zero S will be even close to the Empulse in performance or price. The S is more likely to split the difference between the Enertia+ and the Empulse.

Well they claim 100 + mph and a range of 100 mi., but I bet you won't be able to put the two together. At a more realistic 75 mph, the range is going to be about 35 miles at best. The specs say the Empulse will weigh 420 lbs vs. 341 lbs for the Zero S with the ZF9 battery. Of course they have to get the bike out first so consumers can evaluate it in the real world. I will reserve judgement until then, but the extra weight is a big disadvantage for my style of riding. I don't even like the extra 45 lbs of the 2012 Zero S. I doubt I will like shifting either, but maybe a faster acceleration will offset that. A lack of dealers looks like a problem too. I see they offer a 1-year warranty rather than a 2-year like Zero, but they say they will offer a 2 and 3 year warranty for extra money. Truthfully, I would not want to send any money to them until they start sending out the first bikes and I can read some reviews. The Zero cannot do 88 mph, nor can it go 110 miles in the real world. These are not realistic figures and I suspect Brammo's Empulse nos. are off a bit as well. Still, a true 85 mph would be fine, especially if it gets there in a reasonable time. I haven't heard why they have had such a long delay in getting the bike to market. If it does in fact accelerate very well, go 95 mph or so, and have a range of 35 miles at 75 mph (which is commuting speed where I live), at $14,000 it will be very competitive with Zero. We'll see....maybe.

I have had my Zero up to an indicated 85 mph for a short time and it got there very quickly. It was still accelerating when I had to back off as I was closing in on traffic quickly. I have also been able to hold an indicated 81 mph up a 6% 3-mile long freeway grade. But I don't know how long or how far the bike would travel at that speed. Likely the motor would start to get hot after a while and the controller would back off on the amps and for sure the battery pack would be rapidly discharging too. Fortunately, I prefer getting somewhere without pushing, over getting there quickly.

As the Empulse will have a water-cooled motor and perhaps also a battery pack, it will likely be able to hold high speeds much longer than the Zero, but then that isn't much use to me, as I rarely go faster than 70 mph, even when riding my FZ1 (which gets 50 mpg at that speed).

In any case, I look forward to finally seeing and hearing about the Empulse and I hope it shows up on the street sometime this year.

If the Zero ZF9 can do ~42 miles at 70 mph, the Empulse should be able to do about 52. Maybe 48 at 75 mph.

If you don't want to shift, you don't have to. Brammo has indicated that you can leave the transmission in a particular gear and never shift from 0 - maximum motor rpm. (We'll see if this works in practice when the Empulse actually ships).

I've had my S up to an indicated 85 mph or so - I haven't tried a true GPS-verified top-speed run, but I really should do so.

YMMV obviously applies, but Zero's range estimates don't seem to be grossly inaccurate IME. If your riding patterns look like the EPA UDDS test, I think you'd get close to the 114 mile range figure. I've been getting ranges between 55 and 80 miles per charge in (typically) 40-55+ mph riding.

It's impossible to make an educated guess at how accurate Brammo's range figures are (or are not) without final specifications. A 10 kWh bike should be able to get 100 mile ranges at moderate 45 mph type riding, which seems to be what they're targeting.

I don't expect the Empulse to land at $14k for the 10 kWh bike. I do expect it to have much faster acceleration than the Zero and highway range proportionate to the battery capacity relative to the Zero.

I'm really curious to see the final Brammo specs, and I guess that there are launching delays for a reason...building a water cooled electric motor (and eventually batteries)is not an easy ride...Tesla had a lot of problems when they build the first Roadster with the cooling system, batteries & BMS (they are water cooled).
Do you guys know that the Tesla Roadster has 6800 battery elements inside? (model 18650)  :o

Zero has a very neat approach (naked electric motor) with a lot of limitations when evaluating future incremental power demand, but lots of reliability...the internal motor construction cannot be simpler.

First ever I heard of Brammo some years ago, then from Zero. Zero is the only company that delivers and improves each year. You cannot get better if you do not have decent quantities out there running.
Like the term "naked" bike in relation to the Zero - keep it simple and fun. great.

I started riding motorcycles and scooters 50 years ago and I can tell you that the number one thing that I appreciate is reliability.  All of my early motorcycles, up to the mid-1970's, tended to be nothing but trouble to keep running. Points would close up, spark plugs would foul, valves would float and constantly need adjustment, motor bearings and seals would fail, light bulbs would burn out, batteries would crack and leak acid all over, chains would stretch and break, wheel bearings would fail, clutch cables would break and on and on.  What I want as an owner and rider from a new technology that has a very short track record is something that works and won't leave me stranded.  As far as I am concerned, the fancy, high performance, cutting edge stuff can come later. I like the idea of steady progress using proven and reliable components - and it seems like Zero agrees with me.

It is a mystery to me how Tesla manages to hook up 6800 batteries without making at least one mistake.   ???  If I was doing the job, I would likely make 680 mistakes during the assembly.   ::)

That's what I wondered when I was told about it...I had an opportunity of spending two weekends with one Roadster for free  ;)

The battery -when you compare it with what it delivers- is a piece of art (56Kw/h in a very small package that delivers 215 KW of power -total weight is around 450 Kg) -they get them from Panasonic, the biggest Lithium battery manufacturer in the World...
When talking about Lithium batteries another tricky thing is the way -and how fhysically- you wire them (I mean connection like serial-parallel & very importantly welding among elements)...that's another "secret" that Zero has in his battery pack besides what we know about the chosen chemistry + BMS

TESLA Quote:
"Sixty-nine cells are wired in parallel to create bricks. Ninety-nine bricks are connected in series to create sheets, and 11 sheets are inserted into the pack casing. In total, this creates a pack made up of 6,831 cells. Appropriate cell temperature levels are maintained by a proprietary liquid-cooling system which includes sensors within the pack monitored by the car's firmware. Liquid coolant is pumped through the pack to enable effective heat transfer to and from each cell. The cooling system is so effective that the cells on opposite sides of the battery pack stay within a few degrees of each other. This is important for maximizing battery life, optimizing performance and safety"
