Nice looking scooter. The biggest hassle would be warranty work.

Unlike gas powered motorcycles and scooters, these are very EZ to work on.  They are designed so that you can swap out motors, batteries and controller just by unbolting a few bolts.  There are no chains, no belts, no gears etc.  If a motor goes bad, they ship you a new motor straight from the factory.

Here's one of their S-seroes Motorcycles


When we go visit Surly you'll have to come visit the factory with me and take a few test drives!

Sounds like a lot of fun. I've seen a few of the S-Zero motorcycles for sale on the used market here, in the 4K range. Tempting, but not something I really need.

I'm not interested in the motorcycles either.

However, one of the T-series Scooters would be great to have on the stead to tool around on, chase after loose piggies etc.

They have lot's of good cargo options available and I'm gonna have them add a hitch for a small trailer.




For the stead you don't need a lot of range or speed so you could go for the T-5100 which does up to 50mph with a range of 35 miles at full power and 63 miles at 65% power. $7800 new.

They also produce work trikes

This one has a dumping bed and a 500kg payload capacity.

I knew I could hook you with something.  :icon_sunny:

Perfect for hauling around hay bales, pig feed, bags of cement, your portable solar power system etc.

They will also work with you for custom designs.  Their technology is FABULOUS.  Best motor configuration I've seen.  It's a company started by a bunch of aerospace engineers.

Okay, it's not electric so it doesn't quite belong in this thread but I didn't see a more appropriate one....

That's neat - I'm not so sure about the crash resistance with your kids in it though.  I would prefer a rain-proof lockable cargo box.

ZEV will customize their Trikes & Scooters how you like.  You can have lockable cargo box, passenger seating, whatever.  Also wide variety of power and range options.

Ewz SLA Batt Update and the SUN☼ Convacation in Inman, SC
« Reply #222 on: August 03, 2016, 07:15:11 PM »

I am about halfway through the second summer with the original Battset for the Ewz, which consists of 3 10 AH 12V deep cycle Sealed Lead Acid (SLA) Batts wired in series for 36V.  In theory, this battset will drive the Ewz at a maximum speed of around 15mph for 1 hour on a single charge.  So the theoretical range then on it is 15 miles, unless you carry a second battset, which I have but have never had to use.

As it appears now, the battset hasn't lost any of it's power or charging capability and will certainly last the rest of this year, and probably well into next also.  However, I do not put anywhere near the capacity mileage on it every day, my use for it is mainly Grocery Shopping.  My main grocery store 3 Bears is only around 1/2 mile from my front door, and then while shopping inside the store on the Ewz because it is a very large warehouse type food store I probably put on a mile inside the store.  The other daily uses for the Ewz are to go to pick up my mail from the various lawyers, social security, my Union Pension, electric and gas bill, junk mail etc and then take the daily trash to the dumpster where it will be deposited in some formerly pristine location here in the Matanuska-Susitnat River Valley.  So all together, no more than about 5 miles/day, only 1/3rd the capacity of this Battset.

I have only run the Ewz to capacity on a few occassions.  First when I first got it, I took it on a park circuit around 1.5 miles around for as many trips as I could before the charge indicator went on RED permanently, about 7 trips as I recall.  So that was over 10 miles continuous use full out.  Then on a couple of parades I used it most of the day intermittently, probably putting on total around the same distance.  Generally though for typical daily use, 5 miles is average.

This is ALSO about the same mileage you would put on using it for the "Last Mile" to a light rail or bus station from your McMansion to get to work, then again on the other end when you go from the terminus of the journey to your workplace.  I can in fact bring the Ewz on the Valley Mover bus which goes down to Anchorage for a $10 round trip, which is about 1/2 what it costs in gas to make this trip.  However, even with the lift on the bus, my Ewz are rather heavy and a bit of a pain to get on an off the bus, it is not a real good design on the lift for this sort of thing.  More built for wheelchairs.  There are however more compact Ewz vehicles which are lighter and fold better though, but no real perfect one yet in production.  I am working with a manufacturer to try and get one designed.

All in all, for this type of use, I don't really see the need for Elon Musk's "powerwall" Li-I batts.  The SLA's are perfectly serviceable and a LOT cheaper.  There are also all the Car Batts out there that can be recycled to make these batts without doing a lot more mining.

For the SUN☼ Sustainability Park which we hope to build in Inman, SC, small electric scooters and trikes will be the means for visitors to travel around the park.  No ICE vehicles will be allowed within the park perimeter.  EV Vans, Buses and Trucks will be used to bring park visitors from the "old world" of fossil fuel based life to the "new world" of renewable energy based life.  The park is designed to be a self-sufficient as possible, although obviously to build it we will need to import a lot of stuff from the Industrial Economy with a lot of embedded FF energy in it.  However, once built, it should last a century, if built to the specifications I have laid out, and then after that should be able to sustain at a lower energy throughput for another century. This is what I am going to Inman to sell to the Movers & Shakers in this community. This is what I am spending my Workman's Compensation settlement on.   If I can sell it to them, I can sell it to other small communities.

Whether I succeed or fail, this is how I will finish out my life.  Wish me luck.  As I wrote to the Chamber of Commerce in my proposal letter...

"BUILD IT, AND THEY WILL COME TO INMAN"

scooter-shopping-,meat



Discuss this article at the Science & Technology Table inside the Diner



While I am well aware that there are many Kollapsniks out there who think the situation we are in is irretrievably HOPELESS, I am not one of those depressing nihilists.  I continue to look for solutions, which even if not implemented on the grand scale might be implemented on small scale to maintain some semblance of modern living a while longer.  At least as long as I expect to live anyhow, maybe another 10 years?  After that, the question of how to transition and adapt is no longer my problem, it is the problem of the people still left after I buy my ticket to the Great Beyond.  Meanwhile though, while I am still above ground level walking the earth, I can try to Save As Many As I Can.



So in this episode today, I am going to talk about the transportation problem and the reliance on automobiles for everyone to drive around, doing the daily shopping, getting the kids to school and activities, commuting to work, etc.



http://www.worldincbook.com/images/illus_ch04_trafficjam.jpg Automobiles are really marvelous devices, and I own several of them.  All old used vehicles bought on the cheap and rarely driven these days, but I do own them.  They are indespensible with the current infrastructure we live in to get certain tasks done.  The problem of course with the carz is they are tremendously consumptive of energy and they emit tons of CO2 all the time, which is not doing wonders for the atmosphere or ocean pH levels either.  The traffic jams are no fun either. So they are doing a lot of damage, and if we could reduce our dependency on them, then that extends out our time in transitioning down to a lower per capita energy future.



My solution to this particular problem came as a result of serendipity, it was not something I thought of in advance.  A few years ago even prior to my neck injury, Peripheral Artery Disease (PAD) was making it difficult to walk long distances, much less keep up with my gymmies when out for a run to develop cardio-vascular fitness.  So I bought a small electric scooter to be able to keep up.  It wasn't EZ to get up to Alaska either because of various Hazmat regulations regarding batteries, but I did get it up here with some creative shipping methods.



At first before the neck injury it was mainly a recreational type toy and not used too often.  I rode it in a couple of parades and took the gymmies out for a run a few times.  Today though, it is an indespensible device that increases my mobility, and not only that saves me a huge amount of money on gas for the carz.  It has more than paid for itself over the last 2 years.



So, scooters like this are great for cripples like me, but might they not have a much wider applicability?  I think they could be so useful, and cut total energy consumption by half or even more without a huge change in lifestyle otherwise.



http://tw.on.cc/tw/bkn/cnt/finance/20160220/photo/bkntw-20160220214423310-0220_04311_001_01b.jpg?20160220234119 These devices are far different than the Teslas that Elon Musk is snake-o‎il selling at the moment on gobs of debt money issued by Wall Street.  Those vehicles are basically replicas of an ICE powered car, just they use an electric power plant instead, with the energy stored in batteries rather than in distilled petroleum products like gasoline and diesel.  Their size and weight is approximately the same as a conventional car, so they take the same amount of energy to accelerate and to overcome wind and internal resistance.  That energy generally still comes from fossil fuel powered thermoelectric plants, which might be slightly more efficient burning the fuel, but not that much after transmission losses, battery storage losses and so forth.  The problem here is that driving around such a big hunk of metal, plastic and glass all the time is a HUGE energy waster and thoroughly unecesary for the typical tasks you do each day.



Really, do you need to move around 2000 lbs just to go to the convenience store to buy some milk?  Do you need it to get to work and then leave it in the parking lot all day, and then sit in traffic on the way home too?  Do Soccer Moms really need to function as taxi drivers for their kids to get them from school to their various activities?



In contrast to a 2000 lb car, my current scooter weighs only 90 pounds.  It runs on 3 typical 12V 10AH batteries which give it a range of about 15 miles.  As opposed to Elon Musk's even cheapest Tesla, instead of costing $30,000, it cost $600.  A full new Battset for it costs $150, as opposed to a new Battset for a Tesla which goes for over $5000.



What can I do with this scooter?  Well first off my main use for it these days is to do all my food shopping, as the picture heading the article and this one indicate.



Scooter-Shopping-Nuts



Not only can I ride it to the store to shop for food, I can actually ride it right INTO the store and do my shopping! 🙂 Because of that, I can actually do the whole food shopping expedition in less time than it would take me to drive my car there, park, walk around the store and then drive back home and park again and take the groceries from the car inside the digs.



How much food can I load up on the scooter?  Well normally I only buy bits at a time, so I don't load it up, but if I really wanted to I could drop about 100 lbs of food on to it.  I have panniers for the back as well as the basket on the front, and I can put a case of beer no problem on the bottom platform.  Shopping with it once a week, I would have no problem feeding a family of four.



What about the Soccer Mom issue?  Well, instead of mom driving around the Minivan to get the school for pickup and then driving the kids to activities, the kids do this THEMSELVES on their scooters!  Anybody above the age of 10 or so who can ride a bicycle safely can ride one of these safely, at least as long as there are Bike Paths for them to do it on and not be out in the car traffic.



http://nb9.stumbleupon.netdna-cdn.com/kky7EkGxff1EnyyTdTg6MA These kids can then ALSO ride the scooters to school, reducing the total number of School Buses you need for a given population.  Long as the school is within 5 miles of where your McMansion is, the scooter will get the kid to school inside around 20 minutes or so, at the Federally mandated max speed of 15 mph for such devices currently.  That is way faster than the school bus with all the stops it has to make for individual pickups.



What about Work Commuters?



The biggest problem for work commutes is the "Last Mile" on either end off a Light Rail, Subway or Bus system.  If you live out in the suburbs, your McMansion is probably 2-5 miles away from the nearest light rail station.  So you gotta drive to the station, park your car for the day, get on the train and then when you get to the other end you still might have 2-5 miles to cover to get to the workplace, which you would need a cab or bus to cover.



https://upload.wikimedia.org/wikipedia/commons/thumb/5/57/Interior_of_a_WES_Commuter_Rail_train.jpg/220px-Interior_of_a_WES_Commuter_Rail_train.jpg The scooter solves this problem on BOTH ends, as long as you can take it on the train.  Ride the scooter from home to the station, bring it on the train, get off the train and ride it to the workplace!  Think of the vast reduction in traffic problems you would get doing this, and the concurrent energy savings!   Of course, you would need to redesign the cars and provide more of them to be able to accomodate the scooters, especially on really packed commuter lines.



There are other ways beyond the trains you could do this on smaller scale.  Use one with a 16 passenger van pulling a 15' Trailer to load the scooters on to.  Everybody in your area going to a given location the van goes to loads up in the morning, the van drives to a central location for everybody and then they drive their scooters to work.  Now instead of 16 carz on the road, you have only one 16 passenger van!  It could even still be ICE powered and the energy savings would still be enormous, but also vans are amongst the easiest things to convert to electric themselves because of their design.  Plenty of room for batteries, no problem there.



The biggest complaint I get when pitching this idea is the WEATHER problem.  Rain, Snow, Cold etc.



http://pix.avaxnews.com/avaxnews/f3/c1/0000c1f3_medium.jpeg Well folks, remember where I live. ALASKA! lol.  Yes, there are some days that I do not venture out on the scooter because it is too wet, snowy or rainy.  Never because it is too cold, you just dress for the weather there.  In terms of total number of days in the last year that riding the scooter was if not impossible (forget 6" of fresh snow, I tried it just bogs down and doesn't GO) just real unpleasant and not worth trying, MAYBE it was 30 days worth.  In areas of the country where it hardly ever rains or snows like Sunny California, I can't imagine more than 10 days you couldn't ride.



However, you still would want to have Backup Plans for days that the scooters are impractical.  Easiest there is just to have an old car like I do.  When the weather sucks, I just use the car instead of the scooter.  However the total amount of driving miles each year on the car tires is enormously reduced, an order of magnitude here.  I used to spend 10X the amount of money on gas each year I do now.



https://upload.wikimedia.org/wikipedia/commons/e/eb/Fietsstrook_Herenweg_Oudorp.jpg The next big problem/complaint is the infrastructure necessary here.  These scooters travelling as slow as they do are NOT SAFE to be riding along with car traffic!  They need separate Bike Paths to operate on.  I am fortunate in that where I live has such a bike path, but for these things to be used ubiquitously, the road setup would need to be modified in most places.  A simple way to do it would be to just put a Barrier on current roads separating the carz from the scooterz.  Since there would be fewer carz on the road, you wouldn't need so many lanes for them.  This solution only works for multi-lane roads though.



For single lane roads, you would need to cut a parallel bike path in order to keep the scooters separate from the carz.  However, in generally quiet suburban communities, you can ride relatively safely on the road as long as the car speeds are regulated down to around 25 mph.



So, obviously such a transition cannot be made in all places simultaneously, but if we get the process underway making this transition, just tons of energy can be conserved this way.  If we halve the amount of fossil fuels we use each day, we double the time we have to ween ourselves off of this addiction.  It is the CHOICE of every community whether they wish to do this.  Later this month I travel to South Carolina to try and get one town to begin this effort with the SUN☼ Foundation.



Build it, and they will COME!

Ewz Spare Battset Reconditioned!
« Reply #224 on: May 16, 2017, 03:35:08 AM »
More Good Newz!  :icon_sunny:

My spare battset for the Ewz had been experiencing weird dropouts, where you would drive for a few minutes, then it would just turn off and go blank.  Wait a couple minutes with it off, turn on the machine again, it worked for a few more minutes, then rinse and repeat.  It got me home, but this is not confidence building for a cripple who might have to push it home on swollen legs.  :o

So I brought the battset over to Batteries & Bulbs for testing, along with some other batts I have as well which I bought from them but never worked all that good in the Ewz.  They ran the batts through there testers, and did a drain and fill test as well which cost $5/batt for $15 total (I only had the full 9 yards done on the battset that had the dropouts, not the other 3.  2 of those still seem to be good, 1 shot.  I disposed of that one with them and kept the other two as batts to use to keep my laptop running during blackouts).

After bringing home the battset and installing in the Ewz, I took it for a test drive, doing multiple trips up and down the drive path in to the digs to simulate the length of a ful drive to 3 Bears and back, along with cruising around the store buying Preps.  It worked FLAWLESSLY!  :icon_sunny:  So at the moment, it looks like I will get through the season without having to invest in a new battset this year.  Both main set and spare are now working well.

I have owned the Ewz now for 4 years.  It came with one full set, and that is now my spare and now again still working.  I bought another 3 (it takes 3 to make a 36V system) as a spare the next year, but as I said that one gave out pretty quick.  Then the next year I bought another new set, now functioning as the main set.  So, in total over  4 years, I bought 2 sets of batts to run the thing, besides what it came with.

Each of these 10AH 12V Deep Cycles SLA Batts goes for $50/each, $150 for a new full set.  So assuming I get the rest of this season out of both my current sets, that is $75/year in batt costs, and that's including getting the Lemon set.  What I save in gas far exceeds this cost of course.  Charging cost on my electric bill is negligible, I don't think it even makes $5 worth of difference on my monthly bill.

Also at Batts and Bulbs on this trip they had 12V Li-I Starter Batts for Mortorcycles, ATVs and other toys.  None in the right size for my Ewz though, and also the B&B Pro told me they're not really designed for Deep Cycle.  They are however LIGHT AS A FEATHER compared to a similar sized SLA Batt designed for the same function.  Also fabulously expensive at close to quadruple the price of a similar SLA Batt.

At the moment, the only thing I could see these batts good for would be to have one of them as a 12V storage system if I was down to the point of not having a car and needed to pull it around on a bike trailer or even drop in a backpack out in the bush.  Of course I would not be doing either of those things any more, that is just theoretical.  However, one of these together with my folding 12V 5A solar PV Array probably could keep my needs for keeping my electronics charged and diode lights functioning.

It would certainly be too much to invest to buy 3 of them to see how well they would run the Ewz, particularly since they don't currently come in a size that would fit the Batt compartment and I would have to jury rig some kind of carrier on the back of the Ewz for them.

In any event, I don't need LiI at the moment for the Ewz, as long as they are working as they are supposed to, the SLAs give me more than enough range for how much I will scoot around in a day beore a recharge.  SLAs are also way more ubiquitous, and after the batts stop being shipped over from China, local places will recycle and recondition them.  So for the most part, I think SLA is much more resilient at a better price, and the only reason to go LiI at the moment is if weight is a serious consideration for you.
