Maybe 19S battery charged at 4.1v will work fine with stock X controller? That would be really cool Walking on the edge there. But hey, that's where the fun is. Have yourself a spare controller on hand so your bike isn't down for too long. I was personally underwhelmed doing voltage mods to the sto...

Do you have a spec for the stock controller that shows it's max voltage? Or is this just trial and error. Pulled apart a couple of the stock controllers, gutting them to house the Nuclear controller. The capacitors are rated to 80V form memory. Didn't bother looking up the spec of the mosfets. Fell...

Is it ok to run the stock Sur Ron motor at 22s with a aftermarket controller like the Kelly KLS8430H?

For anyone who is thinking in buildind a custom frame, this could be a great tool:

Hello Gab The bike can top speed at 55-60 Km/h without pedaling. The fastest I went was about 70Km/h in a downhill. Since day one I run my gears with gearbox oil, never heard the sound with the original grease so I really can't compare with the original sound. I like the sound of the bike because it...

Just a quick video made with my friends cellphone:

Looking so much forward viewing your video.. :-D My problem is the BB width.. My bike is 73 mm and the gng kit goes for 68mm :-( anything I can do about that? 73mm is the same as mine and it is compatible with cyclone kit. Don't know much about gng. Next week I will have the camera to make the film...

10.000mAh 48V lipo battery and up to 60km/h without pedaling
I'm waiting for my hobbyking camera to make a video

I can get up to 65km/h without peddaling and with 10.000mAh 48 lipos I get from 20 to 25 Km (little to no pedaling at all)


Soon I will have a camera to make a nice video

Stay in touch

Increasing the tension on the rear derailleur seems to work

One week since and zero times the chain came off

Let's hope I's fixed

This is how it looks now with the new formula brakes:

Not yet

I will borrow a camera from a friend to make a nice video

Stay in touch

For that range with light pedaling you will need at least 6 packs of these: http://www.hobbyking.com/hobbyking/store/__48023__ZIPPY_Flightmax_5000mAh_6S1P_15C_EU_Warehouse_.html This will give you 48v and 15000mAh with a reasonable weight of 4kg in the backpack This charger will charge all your batt...

For your consideration:

Side pics in low gear and high gear:
As Neilp suggested, shall I clockwise the tension screw?
Thank you all for the suggestions

The chain that some times came off is the chain from the inner front plate to the rear transmission (8 gears cassette)

Hello all I'm just wondering what do you guys are using to keep the chain in place without derailing from the front plate. I'n my bike some times when I change gears with no load on the chain the chain came out from the front plate :( it's messy this is what I have in the moment: corrente.jpg Maybe ...

Can you show me a photo of your chain with adjustable sheets?

Tks,
André

Hello mate I have 4 x 6s 5000mAh lipos in 48V 10000mAh setup With this batteries I got about 20Km with almost no pedaling and in a hilly road (conservative discharge from 4.1v to 3,77V) In straight road I get easily more that 55km/h and when climbing and I can get about 43Km/h (both without pedaling...

Here you have my bike with this same kit:

Thanks for the advice Tony! I am now officially clarified about the correct use of the motor :) Today I went for the same trip and didn't have any thermal cutoff. For short times it gave 35Amps to motor but after that i'm running at about 19Amps Also I upper the LVP from 39V to 41V My motor controll...

Yes there is, take a look at this kit:

Did anyone try using thermal paste between the stator and the motor housing? stator removed cyclone.jpg The motor cover was warm to the touch (about 49ºC) when the the thermal cut off was activated (stator at 85ªC) Improving the heat transfer from the stator to the housing surely could fix the probl...

It's a idea!
But still I would prefer something more simple and less messy
