Hobbit's Rans Fusion

[Hyena]

Good to hear you weren't too badly hurt in the stack.
I steer clear of hookworms for this very reason. I know alot of people rave about them but as you've found they can be lethal on grass or loose surfaces - even more so with a FWD. These hoop snakes are great for commuting only on the road but sooner or later you're going to go up on the grass or through a park or something and that's where they'll strike out and bite you on the arse

[megacycle]

Wouldn't be so bad on the arse least got some padding there, always the hands if there's time or them and the noggin as in Hobbs case if its a more abrupt

[icecube57]

Yeah, all the series-ing, paralleling is done on the motor/charger side of the plug. Quite brilliant really. I'm pretty sure thats why icecube deleted most of his photos. Guys were pumpIng him for detailed info, getting him to do all the schematics, then just pulling out and doing it themselves essentially stealing his designs..not fair, damn trolls.

Ya think... right now im at the point i dont really care all the materials and tools they need are going to cost them way more than if they just let me do it. If they did it themselves is going to be half assed or you can tell where they take short cuts. In away its genius but in away you are going to end up redoing it costing more money in the long run.

How you going with the duct tape Hobbs
Got my pig flying now, chewed through 2 halls on the 4060
So meanwhile got my 5404 on that's a beast no rear brakes and havnt sorted regen.
On that is the controller setup for regen?
Mines looking similar changed battery setup.
Black duct tape does look cool though.
I'm going to a guy who does vacuum forming let you know how i go.
Could be an option if you still need a box

[Hobbit]

yeah, I've been meaning to update this but every time I start posting I end up working on the bike some more instead.

So I joined the cardboard aided design team.


and then found plans for a do it yourself panbrake...



and sliced up my 1200 x 2400 sheet of aluminium...still metric shittons left over. I mean...I could make 10 of these.



folded it up into a triangly rectangly thingymagiggy.






and now I'm in the process of jb welding all the joints and adding a hinged side door. Then I'll spray it aqua and see how that looks.

I found a new "shortcut" for the commute. I've discovered the Woronora firetrail. I tried a different firetrail a fair few weeks ago and it was so rocky/bumpy it nearly shook the bike and me apart. scared me off ém but I've taken up surfing google maps as a hobby lately looking to "streamline" my to-work-and-back. I've been up and down it 3 or 4 times and it's awesome. A tar sectioned-off, basically private road that makes my run to work essentially all back streets so I can put a few more kph on with little chance of "commutus interuptus" from the guys who my taxes pay to keep the public safe. It's kinda counterintuitive but the more out of the way the road is, the quicker the commute seems to run.

Now...back to the 7 degrees manshed, WOO!

[Trackman417]

Now that's true craftsmanship right there!I wish I had as much room as you. My garage has so little room, my brother got deterred from making a bike due to no more room after mine
By the way how amp hungry is the 4080? Do you have any efficiency results as to how much amps it eats and at what speed?

[megacycle]

Good to see your making progress in more ways than one.
Like the pan brake, weird name though for a folding machine thingamy.

I was spot welding my sheet steel overlaps using a 20Ah pouch,copper bus and old switch contacts could'nt believe it when it worked, thought it would blow a hole.

I'm only game to ride at night at moment, no rear cluster and brake, piss poor front now after taming the beast when she's chomping on the bit. Of Friday so collect some more bits tomorrow and hopefully road worthy for a long burn, fast charger on board see how fast and how far.

Any thoughts on the regen.

Aye working in the fridge, ice on the screen this morn down ere.
The self regulating charger leads were working well warming my hands, till they went into melt down tonight after 90A-50A abuse on about 1m of 4mm2, need to crank the charger down little now or cut some more 4mm, V105deg
Bloodly freezing after the ride tonight full moon clear skies and gunning it down the back roads.
Wind sheer nearly lost my ears to frostbite, had to get the antifreeze out scull scull.

Hee hee, got YOU fooled. Nah, the box is a bit "melanie griffiths", from afar with a bit of vasoline on the lens it's almost sexy but up close it's more like....



but you know i haven't finished it yet and "not bad for a first timer" has pretty much become my mantra for this build.

as for "power hungry" at 55 amps and 70 volts the motor does about 66kph. I think Hyena has his up to low 70's though. There's been some private discussion that this motor my in fact possibly have a few different winds floating around. I've taken it up a 2 km long hill that rises about 150-200 metres from start to finish at full throttle and the side cover feels about 15 degrees warmer than ambient using a "palm meter"

On my commute 44km round trip is seeing around 18 - 20 wh per km or just shy of 900 wh total with an average speed of about 35 kph. I've peddling less and less and throttling faster and faster to try and find out my batteries limits and I'm running from 4.16 volts down to 3.78 volts. so by these averages I'd put around 57 k's under my belt taking it down to 3.6 V (or my DOD comfort zone) with 18s3p of 8000mah zippy 30A lipo. 9 bricks of the shizzle. I think I'll go with nanotech for build 2 just because.

Hey Megacycle, did you mean you "blew the halls" or sliced through the hall wires? lipo spot welder is simultaneously totally awesome and ice cold shivers scary. You're shorting the battery and that's one way they go pooof. but hey, if it's workin' for ya, then GOOD JOB.

[megacycle]

Mel she was alright till she got the tatts, this is a better shot right

Hang on on were's my glasses Aaarrrgghh.

Yeh i butchered the hall wiring, shortin 2, shoulda swapped the nuts for nylocs in the interim, waiting on custom torque arms, on the steep section of learning curve now.
Took all the halls out and then hang on where the #%# do i get the newies
Now lids off Might do docs mod, now i'm reminded, star/delta for 2 winds in 1

The A123 lifepo4 pouch, looked like a runt, starting to puff up, was surplus to requirements anyhow.
The tabs & copper get hot but the pouch just pumps those welds
Luke live for physics was testing them similar when they first came out, there freaking amazin.

Got day off so time for mods.
Havnt got the ebrake on so popped the controller case open and did the bk-gnd link.
Few guys saying may not need to do resistor mod for regen hvc/lvc for this.
See how it goes.

Yeah there are many different winds of the H40XX motors out there. Hi-power cycles finally got some of them, and started putting "Ultra and super" in with the mix when I emailed them. They have the 4055 motor all the way up to the H4095 . Wanted to buy one of the unmodded ones from them, but not at the price they wanted me to buy them. Hell no
The colder weather is starting to pop up here and I am not investing any big bucks into my bike... until spring

Thats the one thing I hate about this "hobby". Once you start you never stop spending

As for the pics of mel.... I'm gonna keep the vasoline on my lens and call it however beautiful I want .

[Hobbit]

'scuse my MASSIVE photos but yes, I believe cntrl +/- seems to work for gettin' it all in.

This is the Nirve fatass 24 x 3.0 tyre I'm going to run with when I get around to relacing my 4080 into a 24' rim and a 26 x 2.5 hookworm side by side for comparison. The Nirve kinda looks like a kenda flame 24 x 3. The hookworm is on the crystalyte rim the motors came with (fer now). The Nirve is in one of hyena's 2 inch wide rims. After this wears out the next logical step up seems to be 90/90 by 19 size motorcycle tyres (ala Dr bass.)......and moped brakes and front suspension and a 60tooth front chainring and a gopro and nanotech and an onboard charger and a sonic canon for pedestrian control and more amps and........

[megacycle]

Seriously fat and phatttt.
Wicked pattern, won't ask wad they set you back Hobbs.

I'm on the bones of me ass with it all too, good job theres a seat under it all

[Hyena]

Cool, just about to pull the trigger on one of those myself. They're actually not as wide as I thought the'd be next to the hookie, which is supposedly only 2.5" right ?
It's a bit hard to tell from the photo but is there much tread wrapping around the side ? I'm hoping to get it fatter again on my 3" wide rim but it if hasn't got much more tread there's probably nothing much to gain...

Has Doc managed to get a 19" motorcycle tyre on a 24" pushy rim ? Link ?
I know they're roughly the same size but wasn't sure if they're a straight fit. If so... *rubs hands together*
I thought a 20" was closer to fitting, but they're an odd size to find

[Hobbit]

this shows a bit more profile.

[icecube57]

Bumpity bump bump bump. Update pwease.

[Hobbit]

Ok... so Igot fairly discouraged and stalled the progress of the battery box for a little while there. I was considering scraping it and starting over but It's pretty damn close to complete so I'll see it through. The JB weld was a total fail. not sure if i didn't get the blend exactly 50/50 or it was so damn cold that night that it didn't cure right but 2 days later unclamped it and just popped the join apart with a little tug. so I've pulled out the rivet gun and ran out of rivets! I'll grind away the "rivetty bit" sticking inside the box to avoid lipo puncture shudder then cover whats left with neoprene sheet for a smooth cushiony lipo cubby house. The colour isn't even close to matching the bike frame but I was a fraid that it might look a little feminine. I've gone with a matt aqua. might put a clear coat over it for longevity...who knows.





Something else worth reporting to you specifically Mr Icecube, the 50 amp rated Crystallyte controller regularly pulls 55 or so amps at WOT. You put a 50 amp AGU fuse in my harness and a couple of weeks ago, riding along whistling away and the bike died. I looked at the fuse and it seemed pristine but later after getting it home and starting on a checklist of failpoints ( thanks, Jay ) it was the fuse that failed. It seems that 55amps equates to a very, very slow roast. Instead of the fuse burning out it kinda just warped a little bit each time I went WOT eventually breaking but looking "fine". Now, I'm not saying anything bad about your harness, in fact I think they are the Friggin' shizzle, I've put a 60 amp fuse in and it's all good, I'm just noting that the next NOOB who says they are running Crystalyte at 50 amps ( 'cos that's what it says on the box ) may actually be running 55 amps.

Also it seems pretty clear that this motor is NOT a 4080. up against an identical setup in a drag race, ARGH (the other guy) had about 20 or 30% more acceleration. he sees mid 70's kph, I'm seeing 66k's tops. I would love to think it's just some mod i've frocked up 'cos then I could fix it and be too damned fast for my own good but I've got a feeling that our man Kenny has snuck in a sneaky slower wind. I'll pull the cover off and take some piccies soon. In the meantime, I'm off to Newcastle, WOOHOO.

[Hyena]

Looks good mate, maybe add some frangipani stickers on there as well - should finish it off nicely

Yeah you should always run the fuse over, it's not like a controller rated for 50 amps is going to explode and tear a hole in the fabric of the universe if it sees 70 amps or so. My exact same controller is running 100 amps so it's not like you're protecting anything. They're basically just there to stop short circuits or major failures, which with a big lipo pack behind it happy to squirt out several hundred amps could be spectacular.

Also it seems pretty clear that this motor is NOT a 4080.

I'm still not convinced it's not to to with the upright riding position and combined bike and rider weight (not that you'd be much heavier than argh but I reckon you bike would be). I'd be tempted to throw it on a hardtail and see how it stacks upup against an identical setup in a drag race. I'd also be disconnecting the CA for a top speed run to make sure that's not stepping in. What's your freewheel speed on a full charge ? From memory it's high 90s, which is the right wind (reference my test vid of the 4080 that ended up on my fighter HERE

In the meantime, I'm off to Newcastle, WOOHOO.

Have fun, I wish I could make it up, hopefully next year.
For reference everyone else, we're talking about the hunter EV festival. Newcastle isn't ordinarily THAT much of an exciting place

HAHAHAHA yeah, my wife actually refers to to as my "girls bike" because of the bizarre geometry AND a seat the size of a bodyboard.

100 kph so that's promising. Yeah, I reckon I 've got about 12-15 kg's on Argh and I loaded his bike into Millenium Volkswagen, I reckon mine's about 20 kg's over that, too...........Poofy AND fat ...might have to go have a good hard look at myself

[Hyena]

Yes I imagine it's akin to riding an electric bar stood
Having ridden it I dont think the others on the group ride appreciate just how well you did on those rough offroad trails. It's not at all a technical, offroad machine.

100 kph so that's promising.

Ah good, get of my case then asshole . haha

Or you could look at yourself as a bloke out for a laid bike ride on his cruiser, not a jockey on a toey race horse. A change in attitude is alot less work than exercise

Your new battery enclosure, is atleast 10X better than your first one!
............... Not that your first one wasn't good
Nice color, is that spray paint?

How you getting the stock 72V/50's up to 100A.
They modded

[icecube57]

Well I had a failure of my 50A fuse when my bike was peaking at 70-80. It blew in a spectacular fashion... I moved up to an 80A maxi and didnt have anymore problems. For larger controller its hard to size them cause the will instant blow with surge but if its a long moderate draw a fuse can go 125-150% for short periods of time and not blow which is what happened with you. Im offerin the next size up in spare fuses with the latest customers...

[Hyena]

You have much to learn young grasshopper
I had the controllers made beefy as shit coz that's how I roll
The current limit is set at 50a for a variety of reasons, as a default, because most lifepo4 BMSs wont deliver over that, because noobs will burn out motors if they sustain higher currrent draws etc.
Mine is reprogrammed in the software (which as per discussions in my build thread i'm not sure is possible with the later models) but you could achieve the same by modding the shut. For your 5404, solder a copper nail across it* and hang on

* I joke of course, but the 5404 can take as much power as this controller can put out

[Hobbit]

Nice color, is that spray paint?

I bought one of those "poorman's spraygun" kits..so I went and selected my colour out of a book at a automotive paint supply shop. They handed me a tin of acrylic, I mix that with thinners and spray it on, but I etch primered it first. Yippee.

... I moved up to an 80A maxi and didnt have anymore problems.....

Yeah, I happened to have a 60A lyin' around but I'll be getting a 100A soon enough.

Oh really? I'm very glad now I bought 2 of these controllers....sounds like a delicious experiment....MUHAHAHAHA
