sorry man I didn't realize it was that bad. I guess it's best to keep your heart rate at the maximum safe/comfortable level (im totally unqualafied to say shit about it but thats my thoughts) I am/was a fitness instructor at a kung fu school if that means any thing. but yeah with fitness its scientifically proven that more can be gained by doing less times per week a session of short , high intensity intervals(eg run 100m then walk a lap of oval x 10) , rather than a steady pace for longer period almost every day (eg jogging 5km every day).

if you can get down to <10wh/km i think your doing pretty well in any case.

for god sake dont faint and roll the mower back over you, shit!

Are you going to convert a Sachs Madass?

haha yeah but ironically everything on this bike isn't cheap!

It's not really a big deal, 90% of the time I'm fine it's only when I push myself to the point where you'd normally start to lightly puff that I rapidly tend to fall in a heap. I was never what you'd call an athlete so it's not like I'm devestated I can't got for a 10km run or play football or what ever (I used to play soccer and oztag socially but it's not something I'm upset I can't do any more) The only thing physically I can't do that I'd really want to is go out in a decent surf. Ah well, it'll be several years before my kids are old enough that they're able to go out in bigger surf than their old man can. The most annoying thing that affects me daily is my blood pressure, I can't get bend over or change posture quickly without getting dizzy. Like if I drop something and bend over to pick it up I stand back up and the room is spinning. It's annoying when working on bikes, you dont realise how much time you spend with your head down. I've partly gotten around that now though with a hoist from my ceiling so I raise my bikes high when I'm working on them. Of course I still drop tools all the time, I just have to remember to try and squat like a lady :lol: (shut up Aussie Jester :p )

its scientifically proven that more can be gained by doing less times per week a session of short , high intensity intervals(eg run 100m then walk a lap of oval x 10) , rather than a steady pace for longer period almost every day (eg jogging 5km every day).
Cool, I didnt know that. That's pretty much what my ride home is like, bursts of higher level work up hills where my legs start to burn and then back to just normal pedalling.
Today I managed 169whr for the 16km commute - which is 10.5wh/hr, so 10 is definately attainable with a bit more training. I was pedalling my ring off though (chainring and otherwise :lol: ) and it sucked in the warm weathing wearing my big heavy armoured motorcycle jacket. I might have to start ditching that if I'm going to be cruising along slower in the summer. I'm working harder than I'd have expected to maintain speed on the flat (with no power at all) so I'm going to try pumping my tyres up harder - I have them running fairly low PSI because I wanted a comfier ride but with my 2" wide rims the crazy bobs are pretty fat


for god sake dont faint and roll the mower back over you, shit!
Yeah that could end in tears! I usually get warning, I can feel the blood draining out of my head as I start to get dizzy and usually have time to grab someone or something until I stability. Out on the lawn though I had nothing so killed the mower straight away then just kinda crumpled down as it rolled out from under me. haha. There's a silver lining though now, my wife insists on mowing the lawns :mrgreen:
You know the funny thing ? You've heard of the fight or flight response where the body responds to sudden danger or shock or what ever with a raise in blood pressure and heart rate ? That sympathetic nervous system response in me is all buggered up now because the nerves to the heart that cause that response were fried by my radiotherapy (tumor was right on top of my heart). The normal response to a situation like that is the body releases adrenelin and the blood vessels dilate to send a higher flow of blood to the muscles for rapid action if required (ie fight or flight) In my case this happens but my heart rate and blood pressure doesnt go up with it so suddenly all the vessels dialate but my heart doesnt pump any harder and so all the blood essentially drains out of my head. I was never a jumpy person before and I'm still not now but if there's sudden loud noise or something I pretty much get dizzy and fall over. Totally involuntarily, what a pain in the arse! :lol:
Like a fainting goat! (without the muscle tensing bit)
(Sam you didn't realise you were onto something with the goats thing. haha)
My wife dropped a glass the other night and screamed as it hit the floor and smashed. My heart instantly went nuts beating out of my chest, then I slid down the wall and had to sit there on the floor for a few minutes before I could get up.

Sounds terrible, I live for animal protein and sugar :p

Probably, though I'm still tossing around the idea of converting a better bike to start with - something like a CBR125r
I'll ride it in stock form until I get my Ps before I do the conversion so dont want something too crap (which I suspect the stock madass may be)
 
At least with a crappy donor you will want to improve it.
All my parts donor bicycles have ended up being too nice and are permanent additions to the fleet.
E.g. a late model RS125 with nice chassis and electric start two stroke would be too much fun stock, and hard to better when the power band threatens ;)
Exciting times ahead, good luck for the licence tests.
 
deepfraught said:

That's a good point, good incentive to convert to electric if the stock performance is crap. And with a claimed peak power of 6.5kw, 8nm of torque and a top speed of 90km/hr I don't think it'll take many electrons to school stock drivetrain!! Infact I could pull the motor straight off my fighter and have similar performance! As much as I'd like to fit a big ass hub motor for the most naked, head scratching frame possible I think I'll go with the HPM5000 and 350a sevcon 4 style controller. That should give fun performance on such a light weight bike. It's 100kg full of fuel so I'm thinking it'll be around 70kg with all the ICE gear stripped off. But that's atleast 5 months away, I've gotta do a pre-provisional test in 4 months and have it totally legit for that (though I'll be rocking up to my Pre-learner course on my ebike. It'll be interesting what the RTA instructor has to say about it.

Pity you can't get just a gold chainwheel. I'd rather have just it gold and the cranks arms black.

Not sure if you are familiar with this guy: Rennen Design

You can get a Gold chainring in any size between 32-52.9t for $50 posted. Might ask him to forward you some pics of his finished colored rings. I just got a black 4 bolt 104 bcd 52.9t and am very happy with his product. Although the black (mat) finish is not bad it's not particularly impressive either so for your commuter/show bike it may not be up to your standards. I can post a hi-res pic of mine if you wish to have closeup view.
 
Thanks, yeah I've seen them before, good for big chainrings but due to teh flaring out of my frame I cant fit bigger than a 46-48t (I'm going to go with 46t to to be on the safe side)

Back to my boring commuter blog, I pumped my tyres up this morning, up from 25 to 40 PSI. Bye bye tyre suspension :p
On the way home I put in a solid effort and was concious of my power consumption, not using any on the flats and only using it for assistance up grades, and even then still only in low power mode not exceeding around 10 amps. I also logged it on strava so I can keep track of my own fitness as it improves. Interestingly I'm waaay down the public lists for each segmet of my ride that the lycras apparently like to time themselves on. On a number of segments I'm 50-150th position, so a street legal ebike is definately a disadvantage over a good road bike. But I guess we knew that.

Anyway the 16km trip took me 37 minutes making an average speed of 25.7km/hr. As a regular cyclist, seems legit!
I was surprised when I checked my CA stats though - only 146 whr used! So I actually smashed my goal of 10 whr/km with todays ride turning out a 9.1!
It's sort of cheating in a way though, I can make that number as low as I want by just crawling along and not touching the throttle. But it's a good economy milestone to hit. I dont think I'd want to use any less power than that though so that gives me a good theoretical max range of around 70km

Next step, bringing my speed up while trying to maintain that goal of around 10 whr/km
 
You know I got to thinking this arvo about how suitable a carbon frame with a bafang mid drive and small 18650 pack would go with this sort of riding :wink:

I'll test it with the new GNG soon , customs services letter in the mail today...I've seen that if it's not fake there is a new 750W bafang MD too :wink: I can't wait the time of any repair anymore now =)

Yeah I let it go because I wasn't using it any more and really 99% of the people who viewed what I posted there are from here so I just use this thread to ramble on now :p (didnt I always ?!)

dan974 said:

Yeah, that's what I was referring to.
I dont know if it's just a higher amp controller and or if it's actually a bigger motor and they've just used the same photo.
Obviously the 350w one will take 750w but if it's rated at 750 that means we can hit it with double that in bursts :)
I will try one in due course.

Also back to the stats keeping for my commuter - this mornings ride at full power and full throttle the majority of the time with minimal useful pedalling (riding in a collar and tie haha) saw much higher numbers obviously.
38km/hr avg speed with a top of 60(downhill), I spent most of the time in the high 40s when not around pedestrians and traffic.
312 whrs - 19.5 whr/km. So the max consumption is pretty much exactly double my best possible economy so that's interesting.
In terms of time, being 45% faster costs 100% more power. Now to find the sweet spot. I reckon it'll be pretty much right in the middle at ~15whr/km.
My current limit is fairly conservative at 35A, it'd be a different story if it was like my previous commuter that was double that.

It would really suck if one of the 750W fell of the production line and ended up on the 250W line just at the end during product when labeling was happening
:roll:

Indeed, this would be terrible. Unfortunately such things are common with poor chinese quality control. The big chicken motor factory are among the worst for this. We poor end users just have to trust them I guess

In somewhat related news my washing machine blew up the other day, expensive controller board so not worth replacing. That means I get the motor to play with :)

I thought there were 5 phase for some reason but it seems they're a standard sensored 3 phase looking at the wiring - 5 purple wires which will be the halls + 3 pretty pathetic gauge phase wires. Won't take much juice but I might be able to use it for something with a little 6 fet sensorless controller. Or maybe make a wind turbine out of it, I remember reading about people using them for that purpose a while back. A nice scifi looking helical VAWT would look cool in the back yard 8)

there s a new thread on it, and I 've read somewhere that the box is 5 mm wider and that is very silent....48kph stock...

I've got a couple of F&P stators in my shed setup for VAWTS - should you when you're down.
 
Cool, did you retain the existing splined shaft ?
I couldn't get it out last night, not sure what was holding it in. I just got a call from the missus saying the new washer had been delivered and the bloke said he'd take the old one away for $20 which she took him up on. Bummer. Good thing I atleast managed to pull the motor from it, but not sure how I'll go about fitting an shaft to it now... The guy is going to be in for a surprise when he tips it over if he was hoping to salvage anything from it :p
 
Haaha, that is gold, salvaged washing machine without the motor =D

Some sales stuff for the extra bikes and bits you may like to bling up.
I'm not sure on the splines diameter etc. but for cheap shafts Torpedo7 have an under-$10 BMX clearance with axles for $1-2 each with free freight over $50.
Blingy gold front 31T sprockets for $10 too ;) $3 coloured plastic pedals, $10 for magnesium, $2 grips all colours,

If needing extra sets of hydraulics cheap, Cycling Express have white and black option Hayes Dyno hydraulics complete front/rear lifetime leakproof warranty (mixed reviews online, I have sister set of Hayes Ryde Stroker radial masters I'm happy with) with 160mm rotors and bolts for $69 delivered with $10 newsletter first order discount. Hose lengths 85cm front 180cm rear.

Terrible copper fill
Yeah pretty lousy - you should see the size of the phase wires, they're not much bigger than the halls!
I checked the specs online and apparently they put out a whopping 400w. WOW :roll:
Maybe I'll make a clock out of it for my workshop or something. Atleast it looks kinda cool :lol:

Thanks.
I'll check it out but I pretty much have everything now.
I think I'm going to go with shimano saint brakes with a hayes 9" rotor kit. Go large or go home 8)

I swear I didnt pick them because they have a gold banjo on them :p

Total overkill on a commuter bike but I'm more likely to need sudden huge braking power to prevent me being be wiped out by a stupid car driver cutting me off than out in the bush. Plus according to full throttle I wouldn't even know what downhill is :p

I had a feeling all this small motor small current limits pedal lots exercise stuff was a flash in the pan like a detox diet =D

Hey, that's twice the Aus power limit! :mrgreen:

While we're on the washing machine subject - the other day I've estimated my commuter power usage = ~200kWhrs per year
which is the same as an efficient washing machine

It would also cost $44 in electricity (got renewable, so it's more $$)

For that much money I could drive to work for 1 week or catch public transport for 1 week :mrgreen:

haha nah I'll keep it up for atleast another week :p
On a commuter the power to stop is more important than the power to move forward IMO. I had 2 people nearly door me yesterday, one was a huge truck/semi trailer with the bottom of the door at neck height so the door would have taken my head clean off if I was a foot closer. The current brakes I have on the bike (avid elixer 1s) don't feel so good after only 2 weeks or riding and a few hard stops and the rears have a nasty noise/shudder in them. I really do miss regen though, I reckon that'll cost me alot in pads and I've noticed I'm alot harder on the brakes all the time where with my DD motors I'd barely touch them. If the clutch starts to give me issues I think I'll weld it up. It'll be interesting to see just how much drag there is on a smaller geared motor that doesnt freewheel.

True, though it won't be powering any ebikes. I imagine the plastic stator wouldn't hold up well to sustained overpowering either!
2 of them could run my pool pump/filter though which would be cool :)

Nice. I haven't calculated mine but I charge for 8c/kw in offpeak time so it wouldn't be alot. Technically I ride for free with the solar array I have selling back to the grid for 66c/kw, but in any case I have more than enough range to get to work and back on a single charge so could just charge at work if I was really worried about the money. But yeah, when I broke my wrist and had to drive for over a month I noticed the money pouring out of my wallet on a weekly basis. I could have bought a new battery for a 6 weeks worth of fuel.
