GNG, 1000W 48V BB-drive, $400

[Wishes]

Nice video, the Controller seems to respond perfekt if you are able to do that kind of wheelies

I have the 18 tooth 20mm wide GT2 drivers ready to ship but you can't get the full benefit out of them until I have the 20mm wide driven pulley ready. I need my machine shop for that part and I'm putting that together right now. This month both the upgraded primary belt and 219 secondary chain will be available.

1. Is the crank-rpm right for pedaling at 48V with your belt mod and the 219 secondary chain?
2. The 20mm wide driven pulley in the first stage has a freewheel or could be used with a freewheel, so you don't need a freewheel in the secondary stage, right?

What lyen controller should I go for, if I want to use 48V with 40-60a?
Is the 9fet ok or do I need to go to 12fet?

Your better off sticking to 40 AMP and racking up the volts for more power unless you plan on upgrading the phase wires. It you are going to stick to 48 volts, you can use the stock controller with the shunt mod to increase the stock 22 AMPs to the level you want.

Very interested in the 60V 650W kit, how far do you think you can push the controller on this kit ? Is it the same controller as the 450 W kit ?
Also where can I get the lyen contoller ?

Thanks

Email him at Edward@Lyen.com

Tell him what you want to do and he will suggest which controller is best and set it up for you.
Its definately nice to be able to program the controller.

I got one on order and should be here soon. I already have a Lyen controller waiting for it. So I'll test the stock 60 v controller and let you know at what voltage it burns out.

I just got my new Lyen 18 fet high voltage controller and I'm getting some inconsistencies compared the the 12 fet high voltage controller that I used previously.

On the last controller, I set the CA to "Off WOT" mode, which worked just fine.

When I plugged the new one in, this caused the motor to spin/idle without applying any throttle.

I've now got it set to passthrough mode but I'm getting a lower RPM with the CA plugged in. Any idea what I should be setting the throttle in/out values to so I can get full RPM with the Lyen?

I also noticed that the Lyen controller seems to default to medium (#2) power with the three speed switch detached, if I plug the switch back in and flip it to #3 the motor spins faster.

Also, anyone seen the chain primary drive kit anywhere else? I was about to order one but the GNG site is down atm.

edit: it's back up now. I ordered my kit with 1-3 week shipping, but it seems Jon accidentally sent it via 3-7 day EMS because he sent me an e-mail asking for an extra $10

Looks like there's a new reseller in the Toronto area now: http://middriveebike.com/
I think he's ordering direct from Jon and can get the chain drive kits as well.

Someone previously posted this link: http://www.mistertao.com/taobao-products/taobao-item-7018010465.html
Which appears to be the same GNG motor. The seller was not able to provide more pictures but did tell me that the weight is 2.7kg which gives me a price of $100 shipped for the motor.

I just ran into a similar issue. If you have the throttle plugged into the controller, then a quick fix is to unplug the green #6 wire from the CA controller socket (tiny screwdriver required). This will prevent the CA from overriding your throttle. I have a CA3 and the ultimate solution is to plug the throttle into the CA3. You'll then have access to the CA3's awesome throttle features as well.

I also noticed that the Lyen controller seems to default to medium (#2) power with the three speed switch detached, if I plug the switch back in and flip it to #3 the motor spins faster.

I don't have a switch, so I programmed all of the profiles to 99%. I agree that the controller defaults to profile #2 with no switch in my experience.

Hi guys ,
just want to be sure before i make the purchase,is this the motor ??

A friend of mine is coming back from china so i need to be fast

cheers Sava

I tried to order that motor from that vendor through Mister Tao and got a refund a few days later :x

that looks like the same motor that the gng uses, but that cog on the shaft is part of the shaft, so will need to be filed/machined down so that you can fot a cog or whatever you want to fit on it.

[just had another look at it and it says that its a 48v 800w ,, you will need a good battery for that if the 450w is anything to go by, the 450w will easily use 1000w on 48v

I think the 800w is larger, anyone know the various gng motor dimensions available? Would be great to get a nice fat one to mount on a 103mm BB

these are the measurements for the 48V60v800W

 

[bee]

It's the width we're concerned about.

It burned out at 67 volts.

the stock 60 v controller burnt out at 67v ?? dont sound good as normally a battery has more than the stated voltage, ie my 48v is over 50v and my 24v is around 28v ,, so the controlers they are selling for 60v must be crap,, or are they the stock controlers that they sell with the 48v ??

i wonder how much the 48v will take before burning out ,,

I ran my stock 48v controller for quite a while at 14 s lipo / upped to 28 amps which is just under 60 v hot off the charger, never had a problem so I suspect these 60v controllers are just modified 48 v controllers from the original kit.

 

[justlooking]

funny old company the GNG is ,, they upped the belt to sprockets and chain for the 60v unit, and it now looks like they messed it up again with the controllers :|

i dont understand though why they have not put the chain and sprockets on their 48v units ,, unless they still have alot in stock and trying to sell them off first

The stock controller has a burnout level of 61 volts if I remember.

 

[speedmd]

You say it burned out. You mean you overvolted and pop'd the capacitors? Controller should still be fine if you replace the caps if you did not over heat and burn it out.

Yes your right, popped the capacitors, it didn't over heat.

 

[dan974]

there is no security into it ?!? the new 60v is dead @ 67v...:|

 

[speedmd]

Can you still read the values? If so, just get ones like it with higher voltage rating than you expect to use and solder them in.

 

[speedmd]

Something like these should hold up /fit.

The GNG v1.1 stock controller has 63v capacitors. It sounds like the new 60v controller still has 63v caps if it's failing at 67v.

Wishes, did you happen to check the low voltage cutoff before testing the "high voltage cutoff" of the new 60v controller?

Doh, no i did not. Hmmm, I guess I'll take the time to change the capacitors and test it. Back with the info shortly.
