my new E bike newbie here.

[02jze]

hey all this is my ebike i just got given. Need tips on making her faster the cheapiest way possible. Where to buy parts in brisbane , Australia?
its got a 200 watt and 24volt batteries Edit now 48v 450 watt.









EDIT MORE PICS >>>>>>>>>

Next pic is to show the size difference of the 200watt and 450 watt motors.

Nice looking bike,
I don't think you can do much with a 24 volt 200w motor to make it go faster.
If you want to keep the same kind of setup, TNC Scooters --> http://stores.shop.ebay.ca/TNC-Scooters__W0QQ_sidZ132745856QQ_trksidZp4634Q2ec0Q2em14?_pgn=2 now have again those type of motors at 450 watts in 24 or 36 volts (should just bolt up fine)
You would have to change your controller (if you go with the 36v) e-crazyman --> http://stores.shop.ebay.ca/HuaQiang-Nor ... QQ_armrsZ1 would be the cheapest (that i know of) place for brushed controllers.

What type of batteries do you have there ?

Oh... so now ya want FASTER?

nice bike.

does anyone know where you can buy just the frame of one of this style bike? (frame with space for battery)

without buying the entire bike.

[02jze]

in the top pics it has 2x12v 12ah batteries but i have since doubled it to 4x12v 12ah batteries for longer life. Same boring speed but it feels stronger and lasts 3 times longer. Im thinking of having ago at wiring them to 48v on the same set up. and see how i go.

Best bet is going to be finding a 24v e-bike that someone is trying to sell...preferably one with dead batteries, fried controller and locked up motor if all you want is the frame so you can get it cheap. You are in SF, so there should be lots of them on craigslist. You might check with HighTekBikes too. They are near you and Terry may have one laying around or know where you can get one.

Ok so i ride home from work today. get home and my new 6amp charger is there so i throw it on charge. 25 mins its all charged. Normally this took me approx 8 hours being not dead flat. so loving this charger,. Then i decided to wire this baby to 48v. Took it for a hoon down the street and i was kinda scared at first. Im a big fella and this 200watt bike at 48 volts is doing easy 55 to 60 kmph took it for a 5k ride with a 5 mins gap half way to pump up tyres.. Motor is loud gets very warm and i think my chain is stretching. but i fuking love this thing....

[02jze]

Should i maybe charge them slower @ 3 amps ??

heres more pics.

As a rule, slower charging (and discharging) is less stressful for most battery chemistries... Slower chargers (rated as less As) are usually less expensive to buy and smaller/more portable... The smallest A chargers (or best engineered) can also be fan-less (silent.) Lots of reasons to go with the slowest charger you can "afford" time-wise.

It depends on what chemistry you are using.
So what chemistry are you using??
Seems like SLAs, 12v 12ah batteries.
25mins is real quick, especially for slas, heard their charge rate is something like 0.3c or something. you can charge faster but that reduces batt life considerably.
But wait, 4*12v 12ah you can config to 24v 24Ah, a 24v 6A charger can't charge a depleted SLA that fast, can it?? unless of course it was at like 80% state of charge and you just topped it off.

[02jze]

It is only a top up charge but like i said on the same ride my old charger took 8 hours to charge the 12v 12ah x4 batteries now only 25 to 30 mins.
I might just keep it charging on 3 amps with a top up charge time of 2 hours for all four.

I had a stack this morning and broke my carry rack. too much power hahahaha

[02jze]

And now its broke i turn it on and the battery lights come on it shunts but has no throttle resonpse. Have a fried my speed controller ???

[02jze]

Will a 48volt 500 watt speed controller work for my 48v 200 watt set up ??

Always check for loose connections first! All plugs etc tight?

[02jze]

plugs? pfft i cut all them off i use the old twisty method and tape. the hand controller has power but it doesnt go to the motor. The speed controller is in a box and cannot be seen touched all plugs on that are also zip tied on..

Should i buy the 500watt 48v speed controller.??

[02jze]

Will a 500watt controller work on a 200 watt motor ??? I really want to get one on the way so i can ride again..

[02jze]

No one knows an answer to that ???

[TylerDurden]

lol, Yeah, we know...


The controller will be fine, the motor might not be too happy if you pump 500W through it for very long.

thanks StudEbiker!

thats a great suggestion

I'll be watching craigslist.

[02jze]

So the 48v 500 watt controller will pump 500 watt right into the 200 watt motor ? Ill do that untill it blows and start looking ofr a 500 watt motor..

[TylerDurden]

It won't last. Order a bigger motor.....

A loose connection can fry electronics in the controller fast. Twisting wires together is only a temporary fix for very low amp connections.

[02jze]

That motor will hold up to 48v alright ? Or as much as my 200watt 24v will.. Do all throttles suit all speed controllers..

[TylerDurden]

They're cheap motors... get two and run them in series. Search for ES member Kurt's dual setup... others have done dual too.


You'll need to check compatibility on the throttles.
