E-S Stealth Electric Bike Owners

[StealthUK]

Hi all, thought I'd say hello. I've got to say it took me weeks to read all the posts but feel like I learnt more then than since I got the bike and went beyond that in that we are now one of the UK's retailers for them now - talk about convinced by the product!

We've done a load of work on them now (our main business is race cars so we have to mess about with these things) but thus far enjoying our own one and helping out others with theirs (we have one in the workshop for some fine tuning at the moment). Very few in the UK sadly but with the support that we can offer I think that will change. Very impressed with some of the mods going on these from people here - brilliant to see people try these different ideas - bravo all.

If anyone wants any tips on using one of these in the UK just shout. In the meantime, here is a video of us riding round the Brands hatch race circuit on one

That's neat footage, the Bomber on a race track. BTW, welcome to the thread and thanks for posting the video.

Howdy,

i just picked up a new stealth fighter (pretty sure its Hyena's old bike) #131

It's like showing up to a party with my ex-girlfriend. She's such a slut, you're the 4th person to own her in 6 months :lol:
That romp on the beach I posted a few weeks back was our last time together. heh

Welcome to ES! You're living in Sydney now ? We should have a get together at some stage and do a video colab

Is there a way i can make the fighter's throttle more aggressive, i hate this wind-on power curve, i need that instant snappy power for wheelies

Yeah they're a bit tame out of the box, very noob friendly. If you play with the throttle ramps in the CA settings you should be able to liven it up a bit - though only within the constraints of the controller power output.
That said, it looks like you've found it has enough power for instant wheelies for the unsuspecting :lol:

If you haven't seen some of my older vids search on youtube for "when ebikes attack" - the top 3 hits are my vids of people getting pwned in similar fashion. It always catches moto riders off guard.

Rix, to avoid any confusion the MXUS is a standard freewheel on a ~35mm thread.
BMX is about 30mm from memory. Thats not what is on the MXUS.

What's probably causing complexity here is that the freewheel exit hole on the other (nonthreaded) side is just slightly too small for Stealth issue thicker axles.

Yes swingarm slap will need to be checked!

Thanks Sam for clarifying.

Allex, I took the TC4080 a part, vented it, coated with T9 boeshield, and put back together. The phase wires are the same as the 5403 that came on my Bomber, much bigger than the H4080. The stator is 40.5mm wide, I would have taken a pic with my micrometer, but its not digital and nothing would show. 46 magents means the pole count is 23. The quality is much better than the 54xx motors I have had a part, same as my h4080. The casting on the armature is smooth, no pits, the magnets are either polished, or chrome plated. Very impressive motor.

Good to see you join in the discussions StealthUK, hope you also remember to go and create a profile in the Stealth Forum as well. Brands Hatch looks a bit too spread out to really appreciate the fun of the Bomber. See if you can setup some time with a local GoKart facility and get onto one, the bikes are a ton of fun in that format (see http://store.quietrush.com.au/blog/...e-to-race-a-stealth-fighter-on-a-gokart-track I'm busy working with a local race track developer to try and offer something a bit different: http://store.quietrush.com.au/blog/...ding-and-racing-options-for-the-central-coast

Also, Stealth must have been taking notice of the fork investigations work by Emmet, have now switched over to the DNM 8 USD fork as standard. Well done on your writeups Emmett

Other news is that the Fighter battery is now boosted by 40%, will retrofit existing Fighters, but it bumps the overall RRP of the Fighter up a bit to $8500AUD

Details are in a short post at http://store.quietrush.com.au/blog/stealth-fighter-battery-boost-stealth-fork-enhancements

Hyena, there's some good looking sandstone outcrops in the latest vids you've posted. Just a shame they're in Belanglo. Did you see any axe-sharpening grooves in there?

 

[Hyena]

Straight to air cooling Rix, nice. I couldn't even get this motor too bothered putting 12kw peaks through it when sealed so as expected it looks like you're planning to give it a hiding

Cool, now all they need to do is offer a TC80 upgrade and rewire their 40% battery range boost for 40% more voltage instead and their transition to Hyena Spec will be complete

I didn't, but I have to admit I was moving pretty quick most of the time. Fast and silent targets get out alive Did you watch right until the end for the bonus footage ? Skeletal remains! I had to look carefully as I thought it was a human scapula at first. The place does has a quiet, eerie vibe to it, no doubt all just psychology given what went on there and geographically it's not dissimilar to anywhere else I ride.

Yeah i moved up to syd a few months back.

CA Settings:
throttle min output 1.25 volts... it was previously 0.25volts
throttle max output 4.99 volt... previous 3.00 volt

The throttle up Ramp to 0.25sec - prev 1.0sec
throttle down ramp 0.25 sec prev 1.0 sec
fast throttle ramp 0.25sec - prev 0.50 sec

speed limited to 60km/h
I dont know the max voltage for the crystalyte motor for the stealth so i assume 5.00 volt is fine.
all i need is that snappy power to get me to balance point and the rest is all brake control and a little bit of throttle

On a side note, the previous owner had left the bike in a bit of a rough condition, some TLC will fix this. I paid $4k so im happy with that.

.

Funny you mentioned that Jay, I got a pm asking why I wasn't going to oil cool the TC4080, I said, "because Hyena blasted 12kw through his unvented motor under race conditions and it didn't even darken the tint on the stator". If I was limited to the H4080, I would oil cool the that, but I don't think it will be necessary for the tc4080.

 

[Allex]

Maybe it all depends for how long you will pump those 12kW
Nice insides btw. That motor look like quality judging by the pictures shame it is not 45mm stator, would have been more torqe.
It has same deep stator teeth as the Crown, so not sure about how it will run on the adaptto, this needs to be tested.

 

[Hyena]

Nice vid from ze French refm. I like the bit how they tease with the girl at the start then he shoves her away to get on the bike

If I was limited to the H4080, I would oil cool the that, but I don't think it will be necessary for the tc4080.

Yeah, oil shmoil. The only slight reservation I'd possibly have about air cooling is the dusty environment you typically ride in, but given your other air cooled motors have been fine it's all good.

Of course, nothing is bullet proof. But to take 10 laps of a track with constant WOT bursts I think it's a pretty good test. No doubt it you fed it a bazillion phase amps and lugged it straight up the side of a mountain range for 5 miles it'd overheat.

Nice insides btw. That motor look like quality judging by the pictures shame it is not 45mm stator, would have been more torqe.

You have to draw the line somewhere. The upside is you can run a 7 speed freewheel on it, should you so desire.
And yeah, they do look pretty nice inside. You may recognise it from the header on my website.
Here's another 'tasteful nude' shot I took when doing that photo shoot

not sure about how it will run on the adaptto, this needs to be tested.

Adaptto has been pretty vocal about crowns not being supported. I don't see why not and I'm sure it's just a firmware tweak but they seem to be taking the approach that it's easier to just declare the motors aren't compatible rather than fixing the issue. They claim it's a sinewave controller issue which is pure BS considering how flawlessly they run with my similar sabvoton controllers.

 

[Rix]

Yeah, oil shmoil. The only slight reservation I'd possibly have about air cooling is the dusty environment you typically ride in, but given your other air cooled motors have been fine it's all good.

Yah, the dust surprisingly isn't an issue. I do take an air compressor and blow out the stator after each ride, but surprisingly, the build up isnt bad at all.

Remf, thanks for posting the vid link, the French made a good one.

A rider, the data you posted should wake things up at the wrist now. How do you like it?

QR, I heard rumors there was a new battery in development. Thanks for confirming that. Not surprised that Emmett's fork valving experimentation was heard by Stealth, riders like him know how to make their machines work and work well. Seems like I heard Cruzxia experimentation on his rear bomber shock resulted in some DNM shock mods for the Bomber as well. One of the reasons why Stealth machines keep getting better, along with their awesome R&D. How I would like to be fly on the wall in Stealth's shop.

Missed this. I know the TC4080 is a little narrower, but looking at the Justin's simulator, these motors are really close over all in terms of speed and thrust given same volts/amps input. Later this year, I will be able to compare the TC4080n to the MXUS 4t with similar input. But I am guessing based on the simulator that both motors will feel close to each other.

 

[Samd]

I've got both in my shed as well snarling at each other. Its amazing how close they are on the sim. The crown is a nicely presented thing for sure, whereas the MXUS is much smaller for avoiding attention if wanted.

 

[Hyena]

Y'all ready for the big chunk of secret I've been teasing about ?

Unfortunately the weather in Melbourne has been typically rainy so this photo is a bit obscured. I'm sending it down to the CSI IT boffins now to magically enhance the image to crystal clarity




Anyone keen to know details ?
Kinda looks like a cross between a fighter and a bomber doesnt it ?

about bloody time....
seriously though - looks stunning (or, at least it would if I could see it!). Looking forward to some more clarity... :wink:

I can see a derailleur...so that's an improvement on the stock Fighter IMO...that's why I added one to mine.

The controller also looks smaller...Adaptto?

Cheers

 

[Hyena]

The boys from the image enhancement lab have been working overtime and have come back with this



Now, what if I was to tell you that this isn't actually a stealth at all... :?

 

[Cowardlyduck]

Now, what if I was to tell you that this isn't actually a stealth at all... :?

Then I would say, bloody good copy

Come on spill the beans...surely you know more.

Cheers

it looks steeper

If that's not a Stealth then some lawyers somewhere are in for a truckload of work. The title of the pic says FluxB...strange name unless you added A&B

There must be something special about this bike and I think it's high time we know what that is Jay

 

[Hyena]

Sorry I'm feeling a bit sleepy now, maybe we can discuss this more tomorrow ?

Here's another hint: What set my old (white) stealth fighter apart from the other stealths? What sets apart the bikes I've been building lately ?

 

[Samd]

Seat dildos?
