Something important is missing.
But is the rim strong enough to match 10ga spokes? I was told that you want the rim to be stronger than the spokes. - easy to replace a broken spoke than a cracked rim at the eyelet. 12ga are huge as it is..... I guess it depends on your riding terrain.

Yeah that's not a bad idea, but I might embarrass myself as it took me about half an hour just put together all those parts last night :lol:full-throttle said:
I'll do some sort of video of the assembly though.
The main thing missing arrived this morning right as I was about to ride out the door - the frame
I didn't have time to open it as I was already late for work but I'll bust it open tonight. I'm not sure whether to post a pic of the frame on it's own or wait until it's all assembled...
I won't be riding this weekend either way
The above pic shows a HT35 motor but the HI40 (Hyena Industries 40mm :lol: ) motor I intend to run is still in the air - doing the contiki tour of China it seems. The tracking info showed it departing Bejing on tuesday so I was hoping to have it by the weekend as other stuff often arrives in 48hrs. Last night it landed in Shanghai though, on to Shenzhen this morning then missed its connecting flight. Whether it then comes straight to Sydney from there I don't know but either way it's going to be next week now so that kinda sucks. I'm tempted to lace up my last 9C 9x7 I've been hanging on to for a rainy day but I've only got one set of spokes so once I lace this rim thats it for a good few weeks. I guess I'll wait, as someone wise once said, "do it once, do it properly". Mind you that same person probably said "measure twice, cut once" though in my case it's usually measure twice, cut twice - one cut for the job, one for my hand :lol:
Veloman I dare say his sun double track is one of the toughest 24" rims you can buy - if this can't take the spokes nothing short of a moped rim will. I'm running 3" tyres on the back so they're pretty chunky. This bike will be ridden pretty hard and set up specifically for offroad riding. With 7" of travel front and rear it should be a very nice step up from the cheap dual susser I've been riding that has about 1" of rear travel up and down and about 1/2" of rear travel side to side :lol:

Bah dont do that!! show us the frame ya tease! cant wait to see how these HI40's go too. any chance we'll ever see bigger numbers? like HI50+?

Pics tonight or this time tomorrow.
Likewise. I was actually quite happy with the performance of the HS35 when fed a decent helping of current so if I get the same from the H40 without it running right at the limit I'll be happy. 7kw is my goal for this bike, maybe 10kw for nice round numbers
Depends on how this one performs. An aircooled HIT40 should be pretty hard to kill* but going any bigger comes down to price and weight. Bigger gets pricey to start with, and you only have the gangsters interested which means small numbers which makes the price even more. Weight wise I think the HI40 is about as much as you'd want hanging off the back of a swingarm for offroad use. I know the stealth bombers get by with 5400s but I think for retaining some sort of MTB handling you need something lighter. So it's HI40 or bust for this build!any chance we'll ever see bigger numbers? like HI50+?

ha yea im more curios than a potential customer... im starting on a RC drive using an 8080 and a neugart planetary to get away from the spoke killing ht35. going to be force cooling the ht as well though, so it'll be interesting witch works out best. my moneys on the 8080 if I can keep it from breaking chains and other stuff
.any idea what speed you'll get out of the ht40? is it the same wind as a ht35 just wider stators?

I've asked that the HT40 be wound to to 60km/hr on 72v. So it's not strictly a low speed-high torque motor but sort of a middle ground. The HS40 should do 80km/hr on 72v.
Anyway onto my new build, what I'm calling it and the science behind why
During my cancer treatment my white blood cells took a beating. Infact at my sickest the cell count for my Neutrophils dropped to zero. Needless to say, that ain't good!
Neutrophils are white fighter cells and without them you basically have no immune system.
So, with these white fighters robbed from me, I decided to replace them
Behold, The Neutrophil - my white fighter
It was actually a stroke of luck how this came about. When I was pretty crook a guy contacted me and wanted me to build him a bike. I said I couldn't as I was too stick. He said he didnt care what it cost, he just wanted an ebike that went like the ones in my videos. I told him he should get a stealth fighter and he said he liked the idea of if but didn't like the look as it stuck out too much as an electric bike and he wanted to ride it on the street. What he wanted was basically the drivetrain of the fighter on a normal frame, with the battery in panniers. That's when a cartoon light bulb appeared over my head I'd been eyeing off the new fighters for a while but didn't have the funds to buy one. This guy did and he didn't like the frame. So I bought a decent frame, build it up with all the stuff from the fighter and was left with an empty frame in return. BOOYA!
I was going to run 18S3P 5ah bricks but when I saw kepler managed to get 18S2P of 8ah bricks in that sounds like a good way to go. I won't say no to an extra 1ah capacity

Ahhh, the rumours were true, it is a Fighter. Glad to see your health being replenished by a "stealth" injection. Let's all hope that the new Neutrophil is the just what the doctor ordered.
Can't wait to see this come together, you deserve it after everything you have been through.
Best regards, Adrian

damn man, what a killer way to get a frame! though I notice your using a coil shock... I thought the air that came with the fighter would be better suited? or did that go to the guy with the panniers?

Thanks fellas. Yes this is my get well present. SC, yep everything went to the other bike.
So, how much lipo can you fit in a fighter ? That silly Keper guy just wasn't trying hard enough when he jammed 6 8ah bricks into his
Nah, in standard form, with the small screen CA in place it does eat into the space available, but with that removed (I'm running a large screen one) it leaves a little more room for lipo-y goodness.
How much room ? Pleeeeenty
I was originally going to run 18S3P for an 15ah pack but found I could actually fit 18S4P in there - making a killer 20ah pack. I've only ever used 10ah packs on my bikes in the past, with a 5ah booster for long rides so 20ah would be than sufficient. BUT, I could still fit more. I can actually fit 8 5ah bricks in one layer for a 24S2P (10ah) and then a second layer of 4 8ah bricks - making for an 18ah 24S pack. That would be the ultimate long range, high speed machine - twice the power of the bomber in a smaller, lighter package.
I'm not sure I'll go down this road though. My plan all along for this bike was to give it the best performance in the lightest package. I'm sure the HT motor would be brilliant on 24S but I'm not sure I'll actually need that extra range, so I probably don't need to be lugging around that extra weight.
I've only ordered 4 8ah brick so far, so I'll have a play when the arrive on monday and decide how I want to do it.
Another thing I found while playing around yesterday is that I can JUST squeeze a 26" wheel on there - so I might be able to take it for a test ride before I get the motor to lace up to the 24" rim.

OK I think I've decided on my final battery config - 18S 18ah from 6x5ah bricks and 3x8ah bricks.
My 8ah bricks arrived today so I was able to plan out exactly what'd fit. As you can see from the pic there's room for more so I could fit another 3x5ah bricks if I wanted to take the capacity up to 23ah but I'll be happy with 18 for the power:weight balance. I could also still use the small screen CA inside the frame now if I wanted, but I think I'll still go with the large screen one.
Plenty of room for DC converters and even a spare tube and basic tool kit inside the frame.
18ah 24S wouldn't quite fit as I thought previously but that's cool, I'm not going to run that anyway. For others that may be interested though you could run 24S 15ah
Oh, and look what else arrived today

Correct me if I'm wrong but does that HS4080 stand for *HIGH* Speed 40mm stator & 80 km/h @ 36V in a 26 inch wheel?

Not much to show really, taht photo shows where the differences lie - from the side they look identical - only the H35 is dark gray and the H40 is black.
One thing i did note is that the side covers on the crystalyte are exactly the same size as the 9C ones - right down to the screw holes even being in the same place so they're directly interchangable.
I'm not sure what cooling will be like but you could swap the deeper 9C cover for the flat crystalyte one to give you an extra 5-10mm of air gap above the windings, which would be good for air circulation, especially if trying to fit internal fans or what not...

You're wrongremf said:
HI40 was me joking that the HI stands for Hyena Industries because I asked to have them made.
But yes it is a 40mm stator and does 80km/hr in a 26 inch wheel but that's at 72v not 36v. 80km/hr at 36v would be rediculous and the motor would have no torque
