i'm running 83t spur, 28t pinion & stock tyres.. i dont have radar gun so i cant really get the exact speed but my guess would by 55-60mph
Batteries i'm running are cheap 4000mah protek lipos (because i wouldnt think novak would handle high quality lipos anyway).
So now i'm thinking again.... its prob my batts. Didnt think i was going to run my pede so often so went and got cheap proteks =[ i shoulda stuck to good old NeuEnergy =]
