    This frame is awesome. How much $ did it cost? What about a rv120 pro? There was a member here called chupa (or something like that) he cooled his 1680w cyclone so good that he was able to run about 5000w through this little thing. He installed a 20w cooler. This frame needs 15 kw mate...

    Custom Giant Dh, Lightning Rods Big Block, Nuvinci N171

    Some more pics would be great. How much phaseamps do you plan? My small block for example does well with 75 phaseamps. I Heard that the big block is double the coppermass of a smally, do you think it will handle 150 phaseamps? Which max speed have you calculated with the nuvinci?

    Hey Mike it's alex here who ordered some parts from you like the 12t 219 sprocket. I wanted to ask if this 12t sprocket was specially designed for you.

    Was it working before? Maybe you didn't screw the crank correctly into the bottom bracket thread. How does the crank turn when theres no chains on it?

    LightningRods mid drive kit

    Hey wanted to show yousomething for those who want a stronger chain+sprockets. I used the fat kmc 910 chain with double sprockets and it fits nearly without any modifications. The only "problem" is a correct chainline, otherwise it'll make bad sounds :) Hope Mike's parts arrive soon, very...

    Which bolt hole circle is beeing used by mike for the freewheel to 219 sprocket adapter? I Guess its 135mm? The smallest available kartsprocket of this size is 64/63, is that right so far? Which kartsprocket is in diameter identical to 44 bicycle sprocket? I know it's been written here...

    Looks very good Michael. Thermal Goo? Has anybody thought about filling those motor with sunflower oil? Or special thermal oil? Is that thermal goo for better heat absorption? Or better not touch it, as long as it works? :D I'm pushing 75amps peaks (max 10 seconds) through the small block, of...

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

    I think Michael is busy with his work. But I won't get his jackshaft without waiting 2 or 3 weeks for it. So I muddled something together, it works, but needs some more adjustment and some more reduction... Going from 13 to 70, from 44 to 32. I have to order a 22t to replace it with the 44t...

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

    Here are the pictures: Gonna edit later the measurings in here. Didn't have so much time now, I think I will have to upgrade to 219# sprocket, because LR's jackshaft is 12mm diameter? I think Michael Backus uses also metric systems for his jackshaft? 11mm=0.433070866 inches 12mm=0.472440945...

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

    Hey people, sadly my jackshaft broke in two pieces :? Which parts do I have to order from lightningrods? In my understanding the jackshaft should be enough, but do the bearings and the housing (original GNG) fit to LR's jackshaft? I really need some advice :) Please help Greetings from Germany

    BIG BLOCK alternative Motor

    Hi Drum, I think it's both, but i'm not sure. I Can't look at the swingarm and the road at the same time.Maybe I'll ask a friend to ridy my bike and I look closer at the whole story. It's not that it will break soon, I'm only worrying. Got the stock GNG, at the moment and it is very cold, so...

    How do you guys handle with the bending swingarm? I apply 75V@75A peak through my drivetrain, getting serious bending... of course less amps would solve that problem, but a mate told me I got a bending swingarm even at 30Amps, not much it's a bit... Are the special bearings or somewhat I could...
