Doesn't mention anything about ebikes, and god is all knowing, I so I reckon you're fine :lol:

Here's a tasteful nude to go with it

He likes the look of that first raptor photo I posted with the 26" front and 19" rear moto rim so that's what I'm going with.
In fact exactly that set up with the same chunky knobby rears. The battery will be a 21S li-ion unit so 78v nominal and 25ah so just shy of 2kwhr. The raptor frame can take a little more but this is an easy size to slot straight in and it's a reasonable compromise between high power and long range. And there's also the weight and cost considerations.

Sigmacom dropped around on the weekend so I took the opportunity to grab a few snaps comparing the raptor to his stealth bomber. I"ll post those shortly.

Yah Jay, I liked the looks as well, one of the best combos of wheels sizes when mixing MC with MTB wheels as far as looks go, its plain wicked

Yes, its okay to covet other ebikes, as long as they/or you, have the money to fix in case of a crash/stack. Yah thats an ideal battery voltage and ah wise. In fact as you said just the right size and weight is managable.

Jay, how's your spine?
I wish you all the best recovering there.

I'm looking at the raptor frame and considering I'll need a new project after the bmx and I should have a higher income after I become an electrician, I should be able to afford it and will need to reward myself.

The chunky tank is just passable with internal controller , for where I draw the line as what can pass as a bike at a glance.

Is your dealership with the manufacturer going well?

How easy is it put a schlumpf in there?

Cheers

Thou shall enjoy test riding thy neighbors coveted ebike if thy neighbor gives permission.

Thanks buddy, it's still holding my bum to the top of my legs and my head to my shoulders but that's about it
Recovery is slow going but I guess if it was any other fracture you'd have it in a plaster for 6 weeks before you start moving it again so I guess that's to be expected. The general back pain (with drugs onboard) I'd describe more as discomfort and it's something I can avoid by not moving in certain ways but the coccyx is still, quite literally, a pain in the arse! Any sitting related activities are basically like someone pushing hard on a bruise so not much fun. When I drive or otherwise sit at work (a good chunk of my day) I sit kinda twisted to one side so the weight of my upper body isn't pushing down squarely on it, but then that adds to the back pain as I'm constantly like that. My spine is now deviated that way so I'll need a bit of physio / chiro when the fractures heal to sort it back out.

I'm happy to hook you up when the time comes mate! Shoot me a PM to discuss an easy payment plan

Yeah I much prefer it internal and also from a mud and water resistance point of view as much as it being tidier. I have some sample batteries on the way in 25ah capacity that assume an external controller but I'm going to do some fiddling and see just how much capacity can be easily slotted in with an internal 18 fet because I reckon this is a nice way to go for many people who don't need 30ah capacity (and as above the weight and cost that comes with it)

Click to expand...

Yeah so far so good. The distance thing is kind of a bummer but it's working OK all things considered. I'm hoping they'll work with me on making a H-spec revision to the 140 frame and if so you guys will know aaaaall about it

Click to expand...

I believe qulbix are offering genuine schlumpfs now. The genuine ones are needed because they're custom made in a wider length to suit the 83mm bottom bracket shell, which is unfortunately as they're a fair bit more expensive than the ATS copies.
Still, you end up with a pretty badass custom ebike for less than some other options

Exactly Jay, BTW, any luck with that HEB Spec'd frame from Qulbix? More specifically, is it being considered?

Patience, grasshopper

Okay, you got it.

With great power, comes great electricity bill - Announcer at Sydney's Central Station today. Wasn't you by any chance was it jay? Got a secret identity as a train driver?

Wasn't we, I just got my winter power bill and it was only $50. Solar FTW

Besides, I was out helping little old ladies cross the road and volunteering down at the homeless shelter

50 bucks, sweet Jay,

Slight progress on my raptors evil twin.
The pic I posted before was all the parts just layed out on the floor, it's largely assembled now and ready to start on the other accessory bike stuff (brakes etc)
It's taken me probably a little longer than I might otherwise be able to do it, a few hours each night to get to this stage, but I've been videoing each step of the way so I can make a proper frame assembly tutorial. I started doing this with my own build, narrating it as I went but then half way through I just wanted to get it done and kinda left it.
I might end up editing both videos anyway, one more a time lapse kinda overview of the whole thing, the other one more more rambling along a I go

I'm going to suggest the new owner paints the fork guards either black or red. The white doesn't match in with the frame and I reckon either black or red could look quite good. I'd probably go black myself as it could start to look a little too two toned but it's up to him

Thou shall spin out neighbour's axle with thy permission

Yeah what an asshole. Nanoha came by the other night and had a test ride on my raptor, distracted me while I was fitting a H4080 and I forgot to do up the pinch bolts on the already stretched dropouts from the race/broken axle incident. 5kw test, all good, into 12kw mode and seconds later the motor has spun and ripped out my freshly rewired motor :x

You're un-friended Nanoha

On the upside qulbix are working on an additional bolt on pinch drop out reinforcment so this should solve any future issues for people who want to run really big power.

bugga
check and tripple check. my last axle was because the pinch bolts wern't done up (one was)
the drop outs look great on the raptor, sort of almost horizontal angle.

so whats this bolt on bit? like a torque arm thats custom made for the drop out?
edit
btw i can't beleive your getting on 12kw. are you for serious man?!

[quotebtw i can't beleive your getting on 12kw. are you for serious man?!][/quote]

Yah Ken, Jay is serious. Jay, take a pic of the dropouts, I figured they have been pried apart at least 16mm now.

Hey you insisted that I take it for another spin at full power :lol:
I even offered to install the motor for you

Yeah that's right, very near horizontal esp with compression of the shock when you're sitting on it.

Click to expand...

Yeah it's basically bolts on to replicates the shape of the drop out but essentially makes it twice as wide. I also asked that they slot the back of it to allow a little more movement to have it more "pinchy". Once i test the demo (and it works as intended) they'll probably offer them as an option for others.

Click to expand...

serious as a cancer... and I can speak with authority on the matter
I have 2 modes programmed currently - 5kw and 12kw. 5kw is nice for general riding but I reckon 12kw will be good physio to strengthen my back muscles when I'm fit to ride again

Rix, I'll get a pic tonight. They're not as badly spread as you might think - prior to this latest spin they measured around 11mm pretty evenly but with a few little chomp marks from where the threaded section of the axle started to bite in. We actually shimmed the slot with some 1mm steel sheet for the race but I forgot to put this back in when nanoha test rode it (again, distracted chatting to him)
I'm not going to run a 26" wheel on this bike anyway but I'm thinking I might repair the 26" H40 anyway and throw on a thin 1.5" tyre I have no use for and see what happens when you lock on the front brake then give it full throttle. I have a sneaking suspicion there may be smoke 8)

When the axle spun it probably stretched to 16mm and then returned to 11mm. Yah, a 1.5" tire, the only thing that tire is good for is power braking until it blows, and yes, lots of smoke.

Drop out damage:



spread to 12mm. I should have had the new axle just machined fatter!



Also my new projector headlight arrived. As Allex said it's very focused. Good for high beat as it throws a bright, tight square spot but for general night time offroading on a twist track it'll need to be teamed up with a more floody style (like my current light) To that end I will have to fabricate a new front end bracket to mount both headlights on, but that's to worry about another day. I might buy a second one, gut it and make a new less focused front lens so the 2 outer cases match.
It's not as bright as I expected which is a little disappointing. A bit of false advertising, it said 30w but when it arrived the box said 12w with an equivalent light output to 30w (power consumption was exactly 12w). So yeah, that's slightly annoying.
It's a big housing and driver board for such a tiny little single emitter!

You didn't have the TC with the 16mm axle in it did you? if you did, I am surprised the dropout isn't more damaged. On a guess I would say that drop out was damaged by hub a motor with an Imperial sized axle 1/2 x20TPI or about 12.52mm. Am I wrong? I can handle it if I am.

Just as well
My new axle is 16mm, the standard crown axle is 14mm , H40 is only 12mm. I'd say most of the "tapping" of the dropout that occured was courtesy of the H40 spinning. With 10mm flats sitting in a 11mm dropout and 12kw to persuade it to turn that 1/2mm each side of the axle never had a chance.

Yah, I speculated it was an H40 Axle, yours is 12mm? Mine is 12.52mm or 1/2 by 20TPI (threads per inch). I know at some point there as a change in the axle size on the H35 and H40s is yours one of the older ones?

Buying more ebikes than a reasonable man could possibly use really is a sickness
