E-S Stealth Electric Bike Owners

I am a genius and my favorite color is clear

LOL, I haven't heard that one before.

Re: solar. God daaaaaayum HPC You're going to wind up in the sex offenders database with prices like that, that's straight up rape.
I know flexible folding panels are expensive but, wow.
My fighter is technically solar charged as I have a large array on my roof and it could be totally solar charged if I balance charge with the BC168, but it's a slow process.
Even with that $2600 300w one HPC is selling it'd still take the best part of a day to recharge a bomber. So they're not really a viable option to charge while you're out riding. The best use of one I can imagine is if you're out camping somewhere for a few days you could ride every second day, or have 2 batteries and charge one at your base while you're out riding. Or have a decent sized car battery that charges up through the day and then recharges the bike at night. But that defeats the idea of it being light and portable. You'd need a biiig truck sized battery. If it's for a weekender, caravan or any other application though where you don't need it as super portable as possible normal rigid panels would be a hell of a lot cheaper.

Another thing to consider is the solar cells/panels can be connected in series just like battery cells so you could make a custom panel that outputs 90v odd and charge the battery direct. It's probably not ideal if not in constant direct sunlight as the current would drift up and down and lithium technically likes constant current charging but it'd be no worse than the intermittent bursts of high current you get with regen braking.

But back to the above 300w chargers, and in the DIY spirit of ES, you could make your own simple 300w portable stealth charger with a standard folding solar panel, inverter and 300w AC charger for around $1000

Now that shows how durable the whole setup is Great riding.

Good to see the solar question coming up and to hear how others are also approaching it. I've used a couple of options, the first was a DIY setup in my bus, using Jaycar components to put in place a 150Ah slimline battery and 1500W charger/inverter to drive the Stealth chargers. I did a brief writeup of it in this in August last year: http://store.quietrush.com.au/1/post/2013/08/ebike-charging-off-grid-using-renewable-sources.html

Since then, I've been experimenting with more user friendly options that are 'plug and play', to the point of coming on board as a dealer of Goal Zero products via my other company, after trying their big solar generator, which can be daisy chained for increased capacity, either to other GZ gear, or just to a standard vehicle battery with a big Andersen connector. Their Yeti1250 is well suited to the job: http://store.laughingmind.com/products/goalzero-yeti1250-solar-generator even though it's a bit of a lump at 58kg. But I don't have to put up with any generator hum from an ICE option. And after having to pull one apart in Jan 2013 for a service, I sure as hell don't miss it.

Funnily enough, I found myself in a KTM store today, taking a look at the new http://www.ktm.com/freeride/freeride-250-r/highlights.html and having a chat with the dealership owner about the range expectations for them, which turns out to be about 80km, for a 90kg bike..couldn't help but think about how the gap is closing between eBike and motos..there are very few off road places that can be ridden in Austria that aren't private parks, for the reasons that are just plain right about eBikes - noise, trail impact, emissions.. Interesting time to be alive, watching this changeover occurring..

Yah that Freeride KTM 250 is a sweet looking trail bike. It has a similar exhaust to Trials motorcycles which gives it a super torquey power band down low and flattens out on top. I haven't seen any dyno numbers on the 250 free ride yet but I am sure its not putting out anything over 25HP 18-19KW. That muffler and exhaust system wont let it, but it will pull down to idle like a tractor. Yah, its super light and I would love to have one. Not sure when and if KTM will import them to the US.

Looks a bit noisy & smelly. Solution: the Freeride E...only problem there aren't any pedals

not sure of his location though.. im guessing mexico???

KTM Freeride 350 Gets CARB and EPA Approval : http://blog.motorcycle.com/2013/03/...-ktm-freeride-350-gets-carb-and-epa-approval/

there are some threads etc from freeride owners listed here :

[MexicanBatman]

i just sold my freeride 350 as i was using it once every 6 months

where as when i can i take my stealth out weekly

they are a great bike and really surprising, but its such a hassle to go bush, plus the mountain bike park is much more fun...

 

[Rix]

Mexican Batman, just watched your vid, those are some sick lines you rode . With you on the Motos. I sold all of mine and financed the Bomber. Haven't looked back. Once in a while I miss the shooting a sand hill climb on the gas of a 60hp beast but not enough to justify not riding very often and sitting in my garage. If I ever retire and have lots of time on my hands, I will get that Freeride 250 or the electric or the 350 and use it.

Rick

 

[PRW]

I had a 350 Freeride that was stolen 2 weeks ago - great bike, easiest bike to ride I have ever owned. I ended up using it more than my Stealth Bomber offroad. It was also road registered - so I could legally ride it to the nearest offroad area. The 350 4 stroke is vey quiet

 

[Allex]

I re wired the cav3 with throttle in, tempsensor, rs232, PAS and Th0.
.

What does "throttle in" do exactly? I understand that this is using throttle directly to controller instead of having it to CA. What advantages does this gain?

Throttle in means the throttle goes into the CA3 then the CA3 sends out the signal to the controller. The standard setup uses Legacy mode which means the throttle signal goes straight through to the controller.

Advantage of having the throttle go through the CA is that you have many more control features available like temp roll back, switchable current limiting, current control throttle rather the speed control throttle and PAS. Also current limiting is much smoother than legacy mode current limiting.

Legacy mode current limiting needs to see an out of boundary condition and then push back. This is why you tend to get surge then the power drops back when you set a low current limit.

With Throttle in setup, the CA has much better control over the throttle output and as such provides a much smoother method of current control.

Ah, thanks a million for a good explanation Kep!
I was thinking that it would be great if we had a wikipedia about Stealth bikes, collect all the goodies from this thread and have it easy searchable!

 

[Hyena]

Nice vid mexican batman, but if you want to show off you should have turned around and zoomed back up the same

Here's a few pics from a quick outing on my fighter this arvo.
Those who haven't just read my build thread spot the new additions

Nice Jay!
I understand that Crown motor is about the same as stock 5403 on a Bomber but lighter?

 

[Rix]

Tyre Pressures

so i decided to check mine, stock wheels stock duro offroad tyres
ive done about 150km all hard off roading and im 140kg riding weight
mainly fast xc trails and loth of Dh trails with drops and a decent amount of rocky terrain
front im running 14psi and rear 23.5psi
ive got dints in my rear rim from smashing rocks hard and yet no pinch flats
so you dont have to necessarily run high pressures to avoid flats

Missed this earlier, I see the terrain in your video, nice and smooth dirt with a touch of rocks. You lucky Mexican Batman Bomber riding bad ass , I'm jealous. That's pavement smooth compared to some of the crap I ride and I can see why you could get away with that tire pressure. Before I went to MCs, I pinched flatted my rear all of the time. PSI between 25-40, didn't matter the first 4 months I owned my Bomber, I flatted about 8 times per month Not bull$h!t exaggeration. I was flatting at least 2 times a week, every week. Only on the rear though. I have never flatted the front. Of course I am running a MC tire up there as well, but the 24x3.00 Duro, Felt Bermaster, Arrow Primebite, and the Gazzalodi all held up on the front.

Jay, very nice pics, read your TC80 review on your thread so far. Indeed that is impressive as well.

I understand that Crown motor is about the same as stock 5403 on a Bomber but lighter?

Allex, I think the TC100 is just like the 5403, but lighter. Checking Justin's ebikes.ca simulator, with same input values, the TC100 and 5403 are almost identical in performance. Yah the TC100 beats the 5403 in thrust pounds by a pound or two, and about 1MPH faster as well and the simulator shows as much. Based on that, this is what I think is going on. The TC100 has a 3 turn stator like the 5403, the TC80 has a 4 turn stator like the 5404, and the TC 65 has a 5 turn stator like the 5405. Of course I haven't confirmed this yet, but that's what I think is going on with the TCs.

Here is a pic I pulled from the 26MTB/19MC wheel thread of Dlogic's slight bomber influenced super custom one off Raptorlogic build. He is running 18 inch Heidenau K65 motorcycle tires on 18x1.6" rims. Very trick looking machine and very fast . Its also Europe street legal.

This is a great start to what I'm after! I need back up battery to run my fridge when I'm camping so I'm going to look into this over the next two - three weeks and see what options there is! Also loved drunkinKBiths home set up

 

[Rix]

I think a 110volt 1500 watt generator could be the way to go up camping. Running that for 3 hours will cost about 1 buck in Petrol here in the US. Sears and harbor freight sell these types for under 300 bucks all day long. For about 7 dollars, 2 gallons of gas will give you 3 maybe 4 days of riding and charging your machine a couple of times each day. I like the solar option idea, because charging electric with electric is the point of electric.

[Rodflys]

Very new at this posting questions so bare with me please.
I have a 4840 Crystalyte controller and a Crystalyte Racer hub motor powered by a 48 volt 20 amhr Lifepo4 pack.
I have the cyclometer version 2.2 as well. All runs great but would like to convert to 72 volt system for speed.
Can I simply Increase without the need of buying another controller and hub motor?

Tell us more about your controller, do you know how many Fets it is and what kind, I know the 4840 controller is 40Ah @ 40 Volts, is your set up from Electric Rider? If it is from Electric Rider and you have their "Racer" motor as they call it, that could be the crystalyte H3548. When did you get your kit? If its from Electric Rider and you got in 2011 or later, than you may have a 5303. I have to talk with Mike about some other stuff and could ask him about his 4840 controllers if it is indeed from Electric Rider.

WHOO HOO

The bike is back....after a stop at the QUIGLEY MOTORSPORT HOSPITAL my bike is back and on the road

Thanks a heap QMS for rebuilding the bike after a idiot decided to T-bone me at the lights in Adelaide...a few weeks back....

New Frame / and quite a few new components later....and there she is....(all claimed on the "idiots" insurance of course...)

For all your "Stealth" needs....visit - http://www.quigleymotorsport.com/

 

[Murph]

It's been rainy here in the Bay Area and since I commute with my bomber about 8 miles roundtrip I needed some fenders. The first time I took it out in wet conditions without fenders was not pleasant! I picked these up from Amazon for a good price and work well.

They go on and off pretty easy so will be taking them off when conditions dry up. Need to stay Stealth but also like to stay dry!

Looks like a new and improved bike. New frame and lots of components, Q sure know how to fix em good after being wrecked. Glad you are up and running.

Murph, bike looks good, I was wondering if your rear wheel is hitting the fender. Doesn't look like enough clearance from the pic angle.

Rick

 

[Murph]

Haven't had any clearance problems so far. Although I haven't been on any crazy bumpy terrain with them either. There's plenty of room for adjustment higher if need be. I could also attach it to the top portion of the seat post but it seems to work here. Also looks pretty cool.
