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

[Rix]

I think heat had something to do with it. The arrow I have added points to the composite plastic that looks like it melted a little. You can also see it on the other points. I don't think it was the ring gear on the shell, I think it was the drive gear coming off of the motor shaft. How does your stator look? Yep, we had lots of job security over the weekend. After I posted that comment, stopped a guy for 65MPH in a 25MPH, that was good for several hundred dollars worth of Job security.

I have a hard Fizzik seat, and it leaves me numb whereas my foam padded Giant seat did not. Not sure why. Then again, I have another foam padded seat that I did not like either, so...

I'll check out those Brooks saddles though.

If you go that route, let me know how it compares to the Fizzik seat. I had one of those on my Super D and like it, but the stock Bomber seat has been pretty good to me so far.

Jay, thanks for posting the tank slapper video. You let it go for a while, I was surprised you didn't grab the bar sooner.
So we both don't really know why our bikes do it all though yours is freakishly random.
BTW
How was the zombie apocalypse last night?

haha yeah thats exactly what I said previously Sun gear = the centre metal drive gear. And the pics confirm the circumstances that caused it to fail were most likely heat related. I think kepler has run 3kw though similar motors which is probably OK for short hill climbs but would hurt things off the line if you're used to using a DD motor. Oh and the stator is fine. Windings probably slightly darker than normal but totally fine.

Re: saddles, I've heard several accounts that the brooks are good but note that they take time to 'break in'. I'm not that keen on the style though for most of the sort of bikes I have. They look good on a cruiser type bike though.

I wanted to make sure it was obvious, plus if I stacked after just riding around no hands it would have made for a funny vid

Zombie apocalypse ?? Did it come and go and I missed it ?
It's been bucketing down here the last few days. I dodged showers getting to work but got absolutely drowned coming home. A local over was under water up to a foot deep in parts. I decided to zoom through as I was already soaked and the water went from being a few inches deep to up to my axles! The bike made it through OK but I realised afterwards it was probably a silly thing to do with the big holes in my trials rims! The pressure of the tube pushing the rim tape into the hole may have kept it sufficiently sealed though - it didn't feel like I was riding around with tyres full of water this morning :lol:

OH, and I'm now the proud owner of that above pictured madass.
Here's another shot of my new black ass

 

[pendragon8000]

Congrats on the bike man!
Is this so you can ride to work and drop of your son too school next year? Instead of drive.
Apocalypse:

Its like x-men

 

[Rix]

Oh Yah!!! Dr. Frankinhyena is in the house now!

 

[Hyena]

Cool, you know more about what's going on in my backyard than me
I rarely watch TV though so it has to be a fairly major event for me to hear about it.
And no my little fella won't be coming on the moto, I don't think it's even legal to take kids that young ?
I'll still have to do a car trip as there's 2 of them going to 2 different places. Unless I get a pushy trailer but by the time I ride slow enough for them to be safe it's just easier to take the car. I'll be late to work on those mornings as it is.

The purpose of the madass is to build a proper high powered ebike that I can safely take out in public. And when I say safely I largely mean legally :wink: , but also mechanically. It's getting increasingly easy to build something fast and high powered these days with the availability of huge C rate lipo batteries and large hub motors the likes of the cromotor that are built to actually power electric motorbikes and scooters. Obviously I'm all over this like a rash but people strapping these sorts of 10kw+ warp engines to cheap bikes is going to end in tears. The madass is the lightest moto around and the nearest thing to a bicycle that you can register. So I can go all out with the e-power and not have to even pretend it's a bicycle - even though my aim is to keep it minimalist so peoples heads explode when they see what looks like an oversized BMX leaping away from the lights in a blur

 

[t3sla]

Are you going to get an engineer to sign off on it after you mod it for registration?

The zero in my display pic is LAMS certified in Vic.

My logic is no one knows diddly about emotorbikes and assumes they are gutless or there is no power class system like a CC rating, then again some 650 bikes are LAMS so I don't know what's going on


Also these madass things are all over Europe, but are hella annoying due to noise.... esp in a cobble stone alleyway....ugh!

 

[Hyena]

I was wondering what was going on with the zero in your Av. Is that the one you test rode in Melbs ?
Are Zero AU even still around ? I can't find any mention of them currently selling anything.

And yeah. LAMS power rating is 150kw/tonne so some restricted or low powered 650s are allowed. And by restricted it's usually just an easily unscrewed throttle stop that prevents them revving right out when tested. haha. I test rode a ninja 300 recently which had a reasonable amount of pep. It is lams legal (300cc if the name wasnt obvious) and makes 26kw for 174kg weight = 149.4kw/tonne. Talk about running it right up to the limit!
The standard zero S/DS is 40kw and the same weight so even the little extra peak power aside it would hose the 300 with the much greater torque.
The small 2.8kwhr FX has only 20kw but weighs in just over 100kg and supposedly does 0-100 in 4.3 seconds. This is along the lines of what I'll be looking at for the madass (more like 15kw though)

As for getting it engineered, why yes officer, of course
I'll do the mods first and see how it performs. If it's good I'll get it engineered and keep riding it. If it doesn't live up to expectations and doesnt really offer anything over and above my other 250w street legal switchable ebikes :wink: I'll probably ditch the project and buy a fast road bike (I'll be off my restricted license by then).
I have to check with the whole engineering process, I believe once it's been done and signed off the same mods can be done on another bike without inspection. Ie I could develop a standard madass conversion kit for others to legally ride on the road without the expense and hassles of getting it engineered.

 

[t3sla]

Twas indeed, but only rode with regen enabled (not a fan of how that feels)

I'm in a few minds over the bike

In AUS I'd have considered buying it, but part of me believe I'd get more use out of a stealth.
Would be nice to have one as another mode of transport, but due to range it feels like more of a luxury item and even then I'd have to tow it to where I'd enjoy riding it most (like the great ocean road)

When in Europe I'd happily own one and it would be my primary mode of transport, long distance travel is better by train, short distance by ebike and everything in-between this can cover well.

In China I'd just get this instead and stay away from the city while riding, more for clean straight runs

Oddly enough there is another emotor that I saw which was using that sabvoton controller, no idea how much engineering design and testing has been put into these things.... We're talking zero compliance testing, so I'd have to strip it down and check everything

You mean throttle off regen ? If you're used to riding an ICE bike the backoff compression braking type feel is actually a familiarity and in traffic I prefer it. For general riding a good 50% of the time I'd use downshifts and compression braking to slow right down. That said I didnt play with it on the zero and if it was enabled on the 2 I rode it wasnt terribly noticable.

In AUS I'd have considered buying it, but part of me believe I'd get more use out of a stealth.

With a similar price tag for the smaller capacity zero and the bomber the zero would be a no brainer for me.
For general riding anyway, unless you primarily ride in national parks or other places where people with big sticks or ticket books will chase you.
That said, and now to contradict myself, I obviously have a stealth and not a zero. haha.
The deep pocketed answer is I need one of each.

Yeah I came across those a while back. I wonder if the 1500w power rating is almost some sort of regulatory requirement. 1500w on a motorbike of that weight would be comicly bad. It doesn't look overly small scale with a rider on it but he could be a little 5 foot chinaman given the wheels are only 13". haha
Did you see the thickness of dropout material at the back of the swing arm ? Jesus H Allah

They dont look too bad from a distance but this shot tells what the quality is really like. I dont know what part of the bike this is but urggh, I count atleast 5 things wrong with it. Ride at your own risk.

Speaking of e-motos and madasses, there's also this chinese one which is a pretty close knock off and actually doesnt look too bad IMO.

http://baohuamotor.en.alibaba.com/product/753542475-213633969/2013_New_Electric_bike_motorbike.html

Again small wheels (14") and the little currie style motor is no doubt underpowered but this one only weighs 45kg which seems too light to be safe. And that's before you keep scrolling down and find that it folds up too!

Oh My Gosh! indeed!

Looks like one good bump, and you'd have the mudguard acting as a friction brake when the swingarms bend up and things would start falling off as the tack welds crack... (let alone my entire and undying HATE of using AC based connectors for DC charging plugs n battery connectors... Unless it is an outlet so ya can plug in a kettle and make a cuppa on the run !)

[Samd]

Are they called "Re-born motos" because you'll be hoping for an afterlife after writing the current one off on one of their limited edition bespoke deathtraps?

 

[Hyena]

my entire and undying HATE of using AC based connectors for DC charging plugs n battery connectors...

Yeah I despise that as well, recipe for disaster esp if someone comes along and buys a 2nd hand bike. I assume in this case that it's actually an onboard charger but there's no guarantees given the rest of the shocking build quality!

"Here are Re-Born motors you've never been closer to the afterlife. Sick of living ? Let us help you on the next stage of your journey"

3300 RMB is like $600, something has to give!

 

[Hyena]

Yeah I'm pretty sure there's no room for "something" giving when it comes to a motorcycle! Thin metal and dodgy welds like that are not like using cheap plastics on a car interior. haha
Like most things out of China though I'm continously amazed at the price points that things can be manufactured at.
If you must have a Chinese moto the megelli 250R is probably one of the least terrible ways to go and I actually dont mind the look of them. That'll probably cost you a whopping 2k in China though

 

[Rix]

With you on that Jay, I am blown away at the price point that the Chinese can manufacture stuff at. And yes, sometimes there are some questionable corners cut to make that price point. Pisterpro is a great example of this, they make a 230f that competes with Hondas CRF 230f for half the price.

Liking your new toy there Jay

Domestic sales for these items are only marked up 10% from the factory to final sale. So if its sold for 500 its made for 450..... Yeah try survive in that market.... You always have to be focused or you'll go broke in a heart beat

 

[Samd]

Do you pronounce it "me-jelly"? :wink:

Darwinism is brutal in China :lol:

Do you pronounce it "me-jelly"? :wink:

haha the first version a few years ago had a dicky spring or something on the kickstand which would cause it to drop down while hard cornering resulting in the bike attempting to catapult the rider off. Awesome. haha
Apparently they've lifted their game now and they're not all that bad. I do like the look of the frame and would have considered one for an electric conversion if I came across a cheap one. The madass gets the honours though now. I pick it up next tuesday. Prepare for the noisiest 2 wheeled video I've ever posted :lol:

 

[Samd]

Hmmm, a Madass powered sluice....

 

[Hyena]

So I rode through a bit of a puddle... :lol:
