The GNG is SO great but kinda hard to maintain doing what I do :/ The performance is insane really considering its only 1200w max, I have been making so much progress on tail whips! now, I need to find a way to get a new BB :/
...My previous bike with #35 chain sounded like an annoying vacuum cleaner mixed with an electric chainsaw...The pink agni bike was just dead silent...

What chain type did Luke use on the Pinkbike? He had mentioned before that it was a small motorcycle roller chain and was surprisingly quiet, but I forgot the size...
Also, whats the tooth-counts on the new sprockets, looks like it has more reduction than the original pulleys.

Luke was speaking of his twin turnigy motored specilized bicycle. I forget the actual tooth counts, but the differance in noise is directly atributable to the low rpm Agni (4k rpm's) compaired to the Rc motor(9k+ rpm's)The Agni bike (& i think the current death bike) used #428 motorcycl chain.
I can vouch for the "Dead silent" of the current death bike....it is eirie having so much power & the only sound you hear is tires whistling on the ashphault.

I emailed Jon at GNG and ordered a new BB from him. Super fast service as always, a pleasure to deal with.
andynogo said:Maybe try and get the new bb cryo treated or hardened at an engineering firm. Unless it's made of plastic cheese. Just a thought.

Nothing wrong with the music but it would be nice to hear some electric engine sound too. It gives a picture of gearing and handling.
Did you fix the bent BB?

Any idea what the efficiency is like?
