Aussie Ebike Noob needs Help

[Fush]

well we will soon find out...i just sent them an email. On the webpage it says its an Australian motor built and designed here...so i have my doubts

 

[Fush]

ok got a reply from evehicle.com.au this morning...

The texas electric bikes one is similar casing to ours but theirs is 500 watts so bigger windings and higher power consumption. All windings and settings in the controller vary for locations and requirememnts. The USA has a limit of 750 watts. Wish it was like that here.

Dam...but then again they were more expensive then EVtech

I guess the next question i am going to have to find out is... the current BMC hub that evtech have for sale, is it the version 3 or version 2....while I am good at soldering, i would prefer to have some one that is ready to go without having to rewire...(i don't mind re doing the connectors if they are wrong for the controller but opening the thing and resoldering is not something i want to do.

Hmm...just got reply for batterybook.com, a battery supplier in Western Australia, he is selling NIMH F-Cells for $30AUD each for a lot of 40
and $25AUD each for a lot of 60 + $30Freight

Well, I want to add another 12v 10Ah.

But at $30 each, and assuming they are 1.2 v, I'd need 10 = $300. Not economical at all.

My 37v 10Ah Lithium + Charger was A$550. Suspiciously it is exactly the same size as the dimensions for the EV vehicles one.

I've ridden the EV vehicles bike I link above, the SLA version. I don't think the performance was much/any better than my DIY bike.

But I wish I knew where to get those Steel Mozo suspension forks

 

[Fush]

Yeah i just did some quick calculations...it is far cheaper to buy them in the US/Canada even the UK and get them shipped here then it is to buy off that guy...

Kinda proves a point...why the hell do we have to be so far away from everything...and why is everything is so expensive!!!!

Fush -- Again, Have you looked at big Pond and talked to Brett White?

Again - Yes i have...its got lots of info and thats great, but i think i will stick with the BMC, overall it will be cheaper...while its a local shop its also more expensive then buying from overseas even with shipping and it should be easier to setup, especially with the island earth motors, i don't want to hack the controller too much.

I am just waiting to find out what is exactly in the kit from EV tech and then find out when ebikes.ca will have its batteries and controllers in stock..

Really i am just procrastinating atm, have a lovely animation project due on Thursday that i am trying to avoid, that not to say i am not serious about getting my ebike, just there is some other major priorities that sit above the ebike in importance and they need to be cleared before i can start spending up big..hopefully they will be cleared in the next week or two.

 

[BiGH]

ummm i really can't see your math there... sorry the BMC would be about double the cost without batteries or the controller that knoxie and Maytag are using (I'm pretty sure they're using the crystalite 36-72v). AFAIK it doesn't come with any of the kits- you have to buy it - extra cost

i think someone should make a spreadsheet for this kind of thing - *optimal setups vs cost*

either way groundbreaking stuff you're doing for Aus there lets compare notes when we've built our bikes

So what are u doing at uni?

 

[Fush]

Well...at this price

3. X5
Brushless
$850 aud
plus $140aud freigh

its kinda similar price for the BMC if i got it from EV Tech

 

[Fush]

EV tech price is $599 for the Puma/BMC which equates to $701.728 aud, + shipping.

 

[Mark_A_W]

Just for comparison Fush, my motor was $270, including controller and spoked into a singe wall Rim.

I'll see how it goes at 48v

Cool...I tend to be a person that if I spend up big on something i try and get the best...as long as its cost effective...but i would be interested in finding out how fast yours goes....

I really liked the geared hub because while i am quite close to the city it is still quite hilly...and thats the part that really kills me...so something that is has lots torque, light and a descent top speed is what i am looking for...puma does seem to be a match..

G'day Mates
I was just reading your posts, I have a 48 volt, ni cad, 406 c lyte, 36 volt 20 amp controller.(front wheel)
I am a pretty fit person, 170 lbs, and have been a cyclist for years. i push my bike up to speed and really prefer the top end over the torque. ( although i havent tried the higher torque models so cant really compare noob i am). Top speed is about 52 km, per hour, and imo at that speed you need to be on smooth surfaces, when off roading which i dont do much, i go a lot slower, like 15 km/h or so. I am really aware of the wieght of the bike and do not want to put too much strain on the frame, forks or rims.
My daily round trips are around 30 kms, and I have lots of juice left when I get home. It takes about 2 - 3 hours to recharge the batteries.

 

[Nimbuzz]

new, does "top speed" mean pedaling or no?

what kind of bike is it mounted on? 26" rim - ie mountain bike? or 700c ie hybrid?

my bike won't go off road - i'm after a high speed commuter 406-408 sounds about what i'm after at 72v, i've got a couple of hills that i can have a run up for - so i'm thinking prolly 407 or 408, at 72v these should still provide a great top speed!

 

[Fush]

ok well after talking to Bigh last night on MSN...I think i might go for the crystalyte...either 406 or 407...most of my trek is flat with a few steep hills...but its not critical to go full ball up the hill....just as long as it gets me up it...

Hi

The Puma is a torque monster, even on 37V 35A it will climb walls and still top out nicely on the flat, its the best I have tried so far my only concern was the gears, taking a motor apart after 800 miles of abuse i need not have worried as its fine. None of the xlyte motors can match the torque of the Puma low down, i should know as I have tried them all, that said the xlyte motors are still a great option esp the X5 and the dual speed 4 series motors.

I am going to get the Puma factory to make a few upgrades that will make this motor perfect, they need to uprate the windings, and make all the gears metal, this will make a very robust 1KW hub motor, they also need to key the rotor to the gear shaft and thicken and shorten the phase wires.

If they do this they will have an amazing motor on their hands, I think we still need limits, 30mph is as quick as you need to go on a push bike IMHO, the Puma as it is can do this, how ever to do this with long term reliability they need to to beef it up a little.

Just my input

[Fush]

Hey knoxie thanks for that...

BiGH were discussing them the night before last... What i have decided is that I will go for the xlyte in the short term, and then if required upgrade to the puma, that way the budget doesn't get blown.. and if the puma is needed hopefully it will have had the upgrades you where talking about complete so i get the best puma when they are ready...

 

[Mark_A_W]

Knoxie,

Can you expand on the 37V 35A rating?

Is that the max rating of the controller/motor?

Or the actual AMPS that you are drawing? 1300w!!! Bit over our 200w limit....Constable...

My Lithium battery has a 20 amp fuse...



Fush,

How many gears in your Rear Cluster? From Brett I'd probably go the GL2, it's narrow...maybe I should have...dunno..

God that is heavenly! any chance of taking lots of pic and uploading them? Knoxie - ur work 4 the ebike community is excellent

 

[BiGH]

Here i go answering comments for other people - hope no-one gets mad.

yep thats right 1300w. Knoxie made a fantastic video which is on google showing amps and volts on a ride with a HUD on screen.

Problem with the GL1 and GL2 is the motor itsself requires modification to work at higher voltages because u can't get the island/earth or whatever brand it is controllers at higher volts. To use a crystalyte controller, you have to change the hall sensors and the angles that the sensors are located at. :S If you were just going to run them out of the box - i'd def agree, the Gl-2 is a better motor. 40kph out of the box with more torque. But for torque - i wouldn't go past a Puma!

 

[Mark_A_W]

Yeah, I've seen the BMX videos..nucking futs.


Well, the voltage limitation on the GL2 only applies if you want more than 48v (what, 54v or so fully charged?).

Now I've built a 37v (41v charged) system I think that 48v would be perfect (yes, Brett told me that, but getting Lithiums was difficult at the time).

Depends what you want - I want a commuter bike that'll get me to work in roughly the same time as my car.

 

[Fush]

I wanted to go with the xlyte controller...just for the sake that it has the cycleanalyst available for it..and it can upto 72v, i know its possible to do the cycleanalyst without it but..i like the full functionality... as for the island motor..yeah i not sure about it..anyway i sent and email to brett last night...i'll see what he says when he replies..

 

[BiGH]

well i've finally made my order!

time to make my own build thread after i "borrow" the donor bike from my friend heheh

 

[Fush]

What did you end up ordering?

Did you go for the xlyte

 

[BiGH]

yep ordered the 408 in a 26.

also ordered the 72 20a and 72-35a controllers.

the 20a will be used as a backup when(not if) the 35a blows, until i fit betterer fets to it.

now just gotta chase batteries
