Hyena's e-bike builds (now with HD video)

[Hyena]

is like a "Skinny girl with big boobs just to find out she was wearing a padded bra!"

hah, good call. As long as she performs I dont care if she gets hot and bothered and needs the extra padding.

Do they ever use thermal paste on these things? It should really help.

Yep, it has paste, Ive never used one that doesnt

Jay, this really got my attention. You going to have these for sale? I know if you get that to fit your fighter, it will fit the Bomber. I found a line on a 5405 for 400 bucks. That's next for me. Anyway I really like where your future build is heading.

Yeah once I'm happy with a configuration and test it plenty, then make it atleast somewhat noob proof I'm happy to build kits with these. Currently there's alot of stuffing around though to get them to fit a normal bike or even a 150mm axle DH bike so I'll need to consider all that and the costs involved. Cromotors aren't dissimilar and are quite reasonably priced because the guys are buying in bulk. I on the other hand am buying small quantities and currently paying a heap in air shipping then alot of expensive local labour so it's impossible to compete unless I can buy in bulk, have them made to my specs and then sea shipped. We'll see.

Internal frame mounting sounds promising, or a smaller case with fan forced cooling. Or drill a hole through the T shaped aluminium piece the fets are bolted to and water cool it

Yeah lots of options, depending on how silly I go with the motor I may run a small radiator and run both the motor and controller water cooled - but thats a way off yet. I also like my previous suggestion of dual air and oil cooled sealed motor so I'll have to assess all options. I got a spare set of side covers in any case so I can play with different set ups.
And yeah T-man, a CNCd case isnt out of the question, though if I go with a box monococque frame then I'll use just the whole thing as a sink.

& yup, I had an indirect inguinal hernia which was repaired laparoscopically with mesh. Luckily caught and operated on well before the intestines had the chance to push down into my sack :lol:

Ouch. The only thing inguinal hernias are good for is prancing around at the beach in speedos :lol:

Oh and I almost forgot to post a link to my new yosemite video -after spending all night editing it!
Part 2 with Hyena and Rix
Beauty and the beast
(that's yosemite and Rix's bomber, just incase there was any abiguity :lol: )
Beautify scenery of course but also more fast paced action in this one
As usual, watch in full screen 1080p for maximum clarity

Great video Jay, its funny because even with my big fat but you can see a little roost coming off the wheel in the pine needles. I forgot about the creek crossing. On vidoe, it looked easier and smaller than when we were there. Perfect song, haven't hear the Stones in years. My dad sure loves your ebike kit. He has already logged 900 miles on it since last month. Rides it most days 30 miles and sometimes 60 miles with a charge in between.

Fantastic video, Jay It has been many years since I toured Yosemite. It is time to revisit. Looked like you and Rix hit perfect weather

 

[remf]

Yes fantastic vid Jay & Rick...another great ad for Stealth and one for California Tourism as well. I don't think there are many equally scenic places to ride on earth.

 

[Hyena]

Yep, I think the moto tyres played a part too. The bomber leaves quite a footprint behind, must to the dislike of the anti-ebike movement I suspect...

I forgot about the creek crossing. On vidoe, it looked easier and smaller than when we were there.

Yeah the second part was deep, the bomber came to up around the axles briefly as I went through. I editied it out but for the others Rix actually carried his bike across. I remember my jeans were wet up to my knees afterwards

Perfect song, haven't hear the Stones in years

Actually it's a cover by puddle of mudd that came out last year, 40+ years after the original!

My dad sure loves your ebike kit. He has already logged 900 miles on it since last month. Rides it most days 30 miles and sometimes 60 miles with a charge in between

Awesome, I'm glad he likes it and is getting plenty of use out of it.

Fantastic video, Jay It has been many years since I toured Yosemite. It is time to revisit. Looked like you and Rix hit perfect weather

Thanks. Yes we were very lucky with the weather. Rain was actually forecast but thankfully it stayed away for us and didnt start to sprinkle until we were leaving.

I don't think there are many equally scenic places to ride on earth.

Yeah it's certainly very nice, my only regret is not having more time to spend there. Even so it was well worth hiring a car for 2 days and the half day drive each way to get there and back. I should have lied to my wife about my work commitments and stayed longer

I've just finished editing the final vid of my footage from yosemite, I'll upload it tonight.
I think part 2 is probably the best but more nice scenery again of course in part 3

 

[Willow]

digg'n the clip, super sick..... was there a couple of years ago, wish I could have been biking it rather than driving it.

WIllow, just checked out the 2wd trike vid, that's really neat.

Jay, we should have stayed an extra 2 days. Next time, for sure. I really need to bite the bullet and get a GP. Watching the videos that I participated in making is fun. Thanks again for the awesome trip and the great vids from it. BTW, going to build a jig around the bottom bracket, head tube, and seat tube of this frame for a future ebike build. Provided I get into a house with a shop by this winter. I believe this geometry will be perfect. 64 degree head angle, and 17.5 inches from center of bottom bracket tube to top of seat tube. The distance between the seat tube and head tube is exactly one inch longer than the Bomber. Perfect.

Rick

 

[Hyena]

Likewise Rix! What are we going to do next time though? I need to find someone else to hand my bike to at the end of the trip :lol:
If the stars align again and I can score a trip to cali or vegas outside of winter then I'll make the effort to get there again.

Looking forward to seeing what you come up with based on that frame, it looks like good geometry to make a jig from.

OK here's the final yosemite installment - unless I do another remix of the best parts of all the footage, which I may do yet.
It's a shame how the youtube compression butchers these, even on full screen 1080p the quality isnt nearly as good as my local copies.

[Rix]

Another great vid Jay, I remembered how close we got to that deer. Could have probably coaxed it to take food from our hands. Yah, another trip out west would be sweet and we got to figure something out. If I get into a house now, I can probably have a working prototype up and going by Christmas time and that could solve some problems, too boot, getting the Hyena stamp of approval on a custom home built frame. But got to get into a house first.

Hyena,
I ran my H4065 at close to 100v but was only getting a top speed of 100 mph. my unloaded top speed was 51 or so mph. If it was not too much trouble could you check out your unloaded top speed, at 100v? I really wanted to see what land speed records I would break with this motor, but apparently I won't lol.

 

[Hyena]

You got those numbers around the wrong way ? 100 mph is way too fast, and in any case no one ever said this was a high speed motor, infact it's the opposite. My freewheel speed was around 100km/hr from memory so your figure of 51 sounds about right. My flat out run was on 120% timing too. The bike is in pieces now so I cant test the freewheel speed. Check your CA isnt interefering too

 

[Trackman417]

First world ebiker problems :lol:

lol whoops. hmm I should never try to post something on my iPhone . So here's the macbook
My top speed was 42 mph.... Don't ask how I got 100 out of 42

my unloaded top speed was 51 or so mph. If it was not too much trouble could you check out your unloaded top speed, at 100v? I really wanted to see what land speed records I would break with this motor, but apparently I won't lol.

So you were cheating, eh? Yeah I don't have %120 timing on my ebikes.ca controller. I wasn't expecting to be blasting off with this motor on 100v I was just wondering why I wasn't going atleast somewhere your top speed on your H4065 video. Yeah the CA isn't doing any interfering. It has been good ever since I set it up.
Thanks a lot man.

 

[winkinatcha]

Man that scenery is unbeleivable... you green screened it didn't ya? and just taped yerself on rollers

 

[rodgah]

As you say a right bastard to get tyres though, I had to import from the US (thanks again Rix!)

jay I think these are just common 70/100 r19 arent they? what is the section height of the tyre? all fancy brands can be had for around $75AUD in 70/100 as this is a early teens mx bike front tyre size.

 

[Rix]

Rodgah, you are correct, 2.75-19 are very very close to 70x100-19. Maybe MotoZ has a tire? But still for ebikes purposes, its very hard to be Shinkos SR241 or 244 for all around do everything well performance. These are the tires I would be looking for in Australia. Also in the 17 size.

Rick

 

[Hyena]

So you were cheating, eh?

hah, thats lycra mentality man! Anyone faster that you is cheating ? Every bit of performance you can gain through mods and tuning is more than fair game. Suck it princess
But on a serious note you're not the first person I've heard saying they got top speeds shy of what they were expecting with ebikes.ca controllers.
I built a kit for another guy and he loved it, then decided he wanted another so bought all the gear from ebikes.ca and said it wasnt as fast. He had the 12 fet 40a controller which shouldn't have been limiting top speed on a flat road but in swapping it out for an 18 fet infineon he reported much better performance and speed. So maybe that's something to look at, and check your 3 speed switch settings.

hah, a CGI landscape could only end up looking inferior 8)

Thanks for the tip mate.
I did call and visit several bike shops, none had them or wanted huge money for cheap brands (around $150 ea)
I know that the 19" size IS possible in knobbies but I wanted a dual sport tread and it seems these are unobtainium.

I do have another project in the works too. Once my wrist gets better I'm going to get my motorbike license and start work on operation madass.
I'm not sure yet if I'll use my HPM5000, these e-moto hubs or even a 2WD version. I'm leaning toward the e-moto hub because it minimises the extra visual appearance of a motor being there at glance. I've been talking about doing a madass for years but I think with these motors I can probably pull it off with reasonable performance. And with the engine and related components gone it's the nearest you get get to a pushie in a street legal registered moto. Controller under the seat and battery along the underside of the down tube. Or I could even mod/replace the main frame section for something battery filled for ultimate stealth and messing with peoples heads at traffic lights :lol:

 

[AussieJester]

Would like to do a Badass myself Jay (hrmz doesnt quite sound right me sayin it LoL)
Are they available in 50cc model or just the 125cc? Be good to get a 50cc model as
no motor cycle license required just car license...

As always great ootage and editing Jay still, Willow has by far the best shot and edited
e-bike video i have seen on the net! Keep practising you'll get there

Quoted for the ages

Yep, they do make a 50cc model as well though they're horridly gutless as you'd imagine so arent terribly popular. You could probably pick one up cheap as a result though. I'll probably pay around the $1300 mark for a working, good condition 125, get my license on it then strip it down and get to work on the e-mods. I'll have to find a stretch of road to do a split screen video race on seperate days with the stock drivetrain and the new e-drive train.

Thanks buddy. I wasnt setting out to shoot a ground breaking video, just taking a bit of time to move the camera around while enjoying myself there.
When the time comes to shoot a proper promotional video with the express purpose of being awesome and hopefully encouraging sales you'll know about it
I throw my website url in most of my vids now but thats mostly for fun. My site hasnt been updated in like 2 years so if I was serious about it I'd update it. Which I do plan to do shortly.
Again there's the forever ongoing projects getting in the way. Not to mention my pesky family which demands my time and attention

Speaking of madasses, have you seen the madass 500 prototype / concept ? It looks pretty sweet and would no doubt go pretty well with a 500cc donk.

 

[AussieJester]

Would be so easy to cut that top tube of the Badass
replace with a rectangle section of tubing (ala Timma style)
So you can fit 6s lipo packs side by side, fillz that tube with
lipo whack in a perm or Mars 1012 or similar in place of the ICE
motor and your in business...i wonder if hacking into the gearbox
of the ICE would be possible, grabbing a couple of gears from it would be good
if not one speed would still piss along...

KiM

 

[rodgah]

whack in a perm or Mars 1012

dual agni lol

 

[Architectonic]

Those are what, 50-60 kg without motor/gearbox? Hmm.... Looks like an awesome project, unfortunately I don't have space in my garage (or a powerpoint), I'd love to make one of those though.

 

[AussieJester]

LOL Rodger..i reckon my Turnigy CA120 and Kelly would actually mak o of hese PiiiIISSS too
with a HUGE weight saving...I seen a few scooters on here with the Turnigy 80-100s fitted
and they get up to speed limit... if i had the $$s i would definitely do a scooter!

KiM

 

[Hyena]

wonder if hacking into the gearbox of the ICE would be possible, grabbing a couple of gears from it would be good
if not one speed would still piss along...

Yeah I thought of that, but if it's only got a 6kw peak engine behind it normally it's probably not going to be real strong internally. Ideally I want to piss off all traces of the old ICE, and with a hub motor and sine wave controller the thing would be virtually silent. No engine noise, no gearbox clatter, not even any rattle or noise of chains or belts. And to pull up at the lights on that with no visible motor and barely distinguisable battery it'd be great to mess with peoples heads as you blast away Although the sound of a few turnigys parallelled up would be pretty sweet too.
I'm torn as to whether I want something totally silent or something that sounds like it's out of star wars. If I thought I could replicate that harmonic sound of the zero I rode with Luke when I was over there I'd jump on that.

Internal battery in the frame would be good for a short range 'tank' - or even as a reserve. Or I could just oversize it and put the whole capacity in there.
I'm seriously considering getting those nissan leaf cells that were posted in the FS section. It'll cost a few hundred in postage from the US but $1000 odd for a 30ah 100v pack is pretty hard to knock back. Or even use them in their current hardpack format as 60ah cells and just double up. That'd give epic range in a still reasonable form factor.
http://www.ebay.com/itm/Prismatic-PHEV-EV-HV-Battery-LiMn2O4-LiFePO4-20AH-30AH-60AH-A123-Modulle-7-6V-/261218779197?pt=US_Rechargeable_Batteries&hash=item3cd1da403d
11 modules would give me a 22S 60ah pack which leaves a nice safety margin for running 4110 controllers. Charged to 4.15v they'd still be 91v off the charge and should yield a heap of cycles, especially considering I'd rarely take them near max capacity. And with a 60ah pack they'd only be drawing 1C or less most of the time when cruising.
2S3P modules specs are
Length 11.9291" (303 mm)
Width 8.7795" (223 mm)
Thickness 1.3779" (35 mm)
Weight 8.3775 lbs (3.8 kgs)
So around 305x225x 380mm (or double the legth and half the width would probably be more practical) and 42kg. Huge for an ebike but for an emoto that's not bad for 5 kwh. Hmm, tempting. I think 30ah would do me though, even though it'll be more fiddling around if I use those packs...

Though part of me wants to use the lipo I'm familiar with. It'll cost a bit more, around $1500 for 24 6S packs but they're more easily replaced if something goes wrong, and the high C rate means I can burst more power from a smaller pack.

Those are what, 50-60 kg without motor/gearbox?

Yeah probably something like that.
They're 95kg dry in stock form so 40kg for the engine, gearbox and exhaust is probably about right.
I'll measure it all of course when I start. If I use a hub motor that'll add ~9kg back on ( allowing for ditching the stock rear hub and sprocket) and around 25kg for the battery and controller. So all up close to standard dry weigh, but it'll never need any fluids so I should still come out in front. And even if I didnt that's not the point

OK I'm rambling now :lol:

Stopped reading soon as you mentioned 'Hub motor..' as i know it would be all dribble this dribble that duct tape here duct tape here bla bla bla
