The Electric Gardener- Sunday Morning Chain Saws

I got hold of this little gem- a Ryobi 18″ corded electric saw- apparently not available new any longer, but you can find them refurbished and on sites like Overstock.com and that…  for a cool $100. Sears has a nice little “4hp” 18″ saw new for $100 too.  Here’s a saw from McCulloch, too, also $100.

I had a limb to drop off a tree in the back, before winter set in.  Honestly, I didn’t expect too much from a small corded saw, but, first, this isn’t that small.  With an 18″ bar it can handle almost any tree you need to tackle.  It straddles the fence between being light enough to not tire you out, but heavy enough to lay itself into a log and let you let the saw do the work.

Here’s a look at the saw in action-

Sky Cycle Salvage: FOUND!

Many many years ago, there was a junkyard for bikes, tucked away in the outlying boruoughs of Central Massachusetts, not a stones throw from the old Whalom Park – a legend in its own right, and home of a classic, now demolished, wooden rollercoaster.  When I started converting motorcycles, I tried to find them, and there was nothing.  I tried to find any salvage yards for bikes, there is a kind-of lame garage on the South Shore, but nothing like Sky.

Well, after a trip out to Lunenburg, and some sniffing around and some pointed questions, I found them.  Here’s a snap Teresa took while we were there- just one room of the huge space inside the mill you see above:

The address is 109 River Street, Fitchburg, MA.  01420.  Their phone is 978-345-4647.  You can email them requests at skyused07 (at) aol.com.  And yes- they’re used to getting requests from guys like me building electric bikes, and they do buy parts, too.

Talking to the owner, I realized he looked familiar…  it was Fred.  The original owner of Sky Cycle- the Honda/Yamaha/Suzuki/Kawasaki dealership in Central Mass back in the day, and the very same place I bought my beloved 1986 Yamaha SRX600.  New.  In 1986.  That I still ride almost every day.  ”You mean that sweet red bike with the kickstart? says Fred.  Yes, yes indeed.

3 Riders Speak Out on the Electric Ride

You know I’ve been obsessed with trying to describe the electric ride, well, here’s a video I’ve put together: Roberto Locatelli, Assen Jurgen van den Goorbergh and Alan Cathcart talk about their rides-

This comes from these videos:

Thanks for the links, Rich!

Hanebrink All-Terrain Electric Bicycle!

Total coolosity!  Hanebrink is a CA company, their site is here.

Henri the Painter

Everyone approaches projects in their own way…  and throughout the bike, and several other projects I’ve done, the character Henri the Painter lingers in my mind.  There’s always a temptation to make a project last forever, and it’s partly the love of the project itself- once you complete it, it’s over, kind of like not wanting to finish a great book.  Here’s a little description of Steinbecks Henri character, from my own book, Fossils to Flux:

“In the Steinbeck’s “Cannery Row” there’s a character known as Henri the painter.  Henri was neither French, nor a painter actually, and Henri was building a boat.  Henri had, however, a profound fear of the water.  As Henri would approach the completion of his boat, he’d find some reason to dismantle the boat and start rebuilding it all over again- assuring he could avoid confronting his mortal fears.”

You can read the Cannery Row section here, via GoogleBooks. Great stuff.

The Bikes of Japan

Tyler sent this shot – gas, but the electric possibilities are undeniable, no?  Especially if you happen to have a HUB MOTOR sitting around all fixed up?  (muwaHAHAHAA)

Ahhh…  a little research, and it’s a Honda Motocompo- a folding scooter thing that was made in the early ’80s.  Here’s the Wikipedia on it.

Oh, and here Ty- a little movie for ya…

This just in!  Over on the PlugBike, you got your Moto Ponco folding electric scooter!  SWEET, and thanks skadamo!

The Controller Guts

Since my Hall sensors seem to be OK, I’m moving on to the controller.  Here it is, pulled out, with the cover off.

Sensorless Controllers- (Dept. of Who Knew?)

In the process of doing my hub motor repair, someone mentioned something that I’d never heard of- a sensorless controller.  That is, a controller that doesn’t rely on Hall sensors to determine where the rotor is, and when to feed what to where to make the motor spin.  Magic, pure and simple.  Here’s a link to one of the controllers available on EBAY.

Apparently the controller can tell where the rotor is directly from the drive wires.  To quote Bruce in the ElMoto thread: “They either look at the third leg while driving the other two if it is a two phase at a time type or they can measure the back emf on all three to infer the position of the rotor. This type of controller could care less if you originally had sensors, the more compicated circuit internal to the controller makes the sensor unnecesary.”

I don’t know what EMF is.  Wait.  Google.  EMF = electromagnetic field.  OK, that makes sense.

Unfortunately the item on EBAY ships from China- and the shipping is almost the same as the item itself, at $24.  I had a bad experience with China EBAY purchases, the last one I bought took 6 months to show up.  It would be a fun little twist on my repair project, though…  stay tuned!

Feature: Electric Bikes of New England

Finding the right formula for any retail business is tricky stuff, not to mention for products like electric bikes, but Paul Morlock of Electric Bikes of New England seems to be on the right track.  After a couple of years in business he’s seen a virtual explosion in interest and sales of all sorts of electric vehicles, from bicycles and mobility scooters right through to electric skateboards and scooters.

I’d heard about Paul through various links on the web, and exchanged a few emails with him.  I decided to jump in the truck and ride on up to his shop in Derry NH to see what it was all about.  On our way to the shop, we passed by a guy loading an electric bike into a wagon – and it happened to be Paul, just finishing up a sale.  These customers had searched high and low, and, once they found Paul they made the trek from the Providence, RI area to get their bike…  Paul said he gets people from all over New England, even from New York and Pennsylvania – stopping in on their way through to their vacation destinations on the coast of New Hampshire, Maine, or the White Mountains.

He stocks and sells mostly bicycles, and carries everything from the stock Schwinn, through the Ultra A2B, on into some bikes he orders and builds on a custom basis.  Most of his customers are in the Boomer generation- folks who want to be outdoors, enjoy the ride, but whether they can’t keep up to the group they like to ride with, have been injured, or simply enjoy a little help on the hills, the range of power options from electric assist to full electric power fits the need.

Paul also sells the BionX conversion kits and parts, and stocks a good array of replacement parts such as lithium and AGM battery packs for several models, accessories such as racks, lights and the usual bicycling toys, and also motors and repair parts.  Of particular interest to me are the Golden Motors, for which he’s also a dealer.

Golden has a great hub motor, one, the MagicPie in particular that has good power (up to 1000W), can lace to any bike (and small motorcycle) rim, and has an incorporated multi-voltage controller. They also have a cooled BLDC motor that’s rated at 10KW.  I wants.

Paul isn’t particularly interested in motorcycles at this point, since he’s got his hands full with the bike business, but we had a great conversation about the future of two-wheeled electrics and what we may see coming this summer.  He’s not had any experience with the Golden Motors in a motorcycle yet…  but I’m looking forward to hearing from his sales rep about their experiences with that soon.  Look for an update here.

As far as the electric retail sales model, it seems like Paul’s hit the bullseye.  Catering to virtually everything that you get on and ride for assisted transportation and powered by batteries, he’s got it covered.  He’s using much the same formula, within bounds, that BestBuy is talking about – a soup-to-nuts electric “superstore”.

One of the interesting observations I was drawn to in talking to him is the client base.  His clients are interested in some very different things than a motorcycle buyer…  he does get requests for scooters like the X-Treme and Veloteq, but he’s not getting people coming in looking for an adrenaline rush as you’d see in an electric motorcycle dealership.  His customers may be more interested in the practicality, ease of use and commuter applications than the thrill and fun of a high-speed ride like the Brammo Empulse.  You can start to understand the product placement strategy of BestBuy, when you see it in that context.  A dealership, as I’ve been thinking of, with everything from Razor scooters up to Mavizen and Empulses is possibly as impractical as selling high-end motorcycles side-by-side with gas scooters and BladeZ powered skateboards…  they simply are very different customers.

All in all, a great and informative visit…  Thanks Paul, and good luck in the coming year!

Interview: ZOE!

Zoe Rem, awesomely awesome pro rider, who’s competed with the AFM since ’08 and made her pro debut on the TVG.com Honda CBR600rr in AMA Pro SuperSport at Laguna Seca in 2010, also has a B.A. in Religious Studies, is a certified Nuclear Reactor Operator and has a day job at TVG.com.  No slouch, this one, and willing to answer my endless questions with grace and style.  Read on, for Zoe’s take on electric bikes, noise, gas, and being a woman in a brand new sport.

Some background:

“I’ve been riding dirt bikes for about 7 years, and I raced Supermoto for a year before road racing. Both dirt and supermoto have been incredibly valuable for developing my riding skills and I still ride a lot to train, along with yoga, bicycling and a bit of lifting. I’ve been racing with the AFM for the past three years and this year has been full of ups and downs. I road an SV650 for the first two years and got a ride on a Ducati 848 for the first part of this year, which was totally amazing. My plans for next year include all the California rounds of AMA Supersport and hopefully the complete TTX GP series.”

On the Electric Race scene:

“There was definitely come sniggering in the paddock, but after people saw the battle that took place at the opening North American round at Infineon, everyone seemed to realize that it’s just as cool as gas bikes. And the fans are way more enthused. E-bikes have a following that’s way more loyal and deeper than gas bikes, because people really care about them in a more personal way. Many of the fans you talk to are involved in some way, building their own bikes or something, and it they all just seem so much more interested in the development of it as a sport. It’s probably what gas bike racing was like 50 or 60 years ago (or whenever it was in its infancy); it’s a different kind of feeling knowing everything’s new, no one knows the right way to do it, and no one’s sitting around in a big factory trailer with all the secrets. That makes it exciting.

The TTX GP series and Team Agni have furthered my career this year in a way I never imagined would happen when I first twisted the throttle of an electric bike. So electric bikes have certainly opened a wonderful new door for me”

On the Electric Ride:

“Since I’ve been racing the electric bikes, probably the most common question I get asked is what the difference is from racing a gas bike. And honestly, I don’t find it that different. The power is obviously really different than your standard motorcycle, but it seems to me just like the difference between riding an inline four or a twin, or a two stroke. This past year I had the opportunity to race a bunch of different bikes and found myself switching from a Ducati 848 to the Pril Motors e-bike, to a CBR 600, to the Agni Motors electric and back. For a period of time, each time I got on the track I was on a different bike. So part of my comfort in racing electric bikes might just come from forcing myself to get on whatever’s in front of me and ride as fast as I can.

However, I think the e-bikes feel most like a very low powered two stroke, especially with the lack of engine braking. The power band is really torquey and either it’s all right there, or you’ve got nothing, like a 125, when you’re not on the pipe, there’s nothing. And while there’s nothing you can do to the e-bikes like you can by keeping a 125 high in the revs, it’s still a similar kind of feeling to me of having all or nothing power.  Not being able to rely on any engine braking is probably the most difficult thing for me, especially coming off the 848. But it’s just another skill to pick up.

All of the e-bikes I’ve ridden have had some kind of throttle lag, which I think is just a part of technology which can be overcome, but that’s what has been most difficult for me, because you have to plan ahead to compensate for the lag. Instead of opening the throttle when you want to start accelerating, you have to open it a second before hand so that the bike actually accelerates when you want it to.

The Agni bike is incredibly maneuverable for its weight (which is only 100 lbs more than the GSXR from which it’s made). And overall, the e-bikes are really fun to ride, and getting so much better technologically. It’s amazing. But to me, it just feels like any other motorcycle”

On being a woman in the sport:

“The TTX GP has been helpful in attracting sponsors and being a female has always been huge in attracting sponsors. Because I’m a female I do not think I can ever be purely performance based. It will always be the whole package. Even Elena Meyers, the first woman to ever win any AMA national, and she’s 16, but it’s so amazing because she’s a girl. Anytime anyone speaks of her it’s because she’s a 16 year old girl who can hold her own against the boys. It’s never because she’s just an amazing rider.

So definitely, being a female in this sport has worked to my advantage. It’s the difference between the electric scene and the gas scene that I can’t seem to work out. Whether the electric-female combo is more significant than the gas-female combo. Proportionally, there are far more women in the electric field, which is great, but makes me wonder, and I can’t pin point it.”

Thanks Zoe, and here’s to a great year in 2011 of kicking some righteous (electric) butt!
