Re: My Felt 1903 build progress
It wasn't so much a vibration as it was a twisting action on the bottom bracket. I have had time to think about it and I don't think you will have a problem. I use a shift-kit and the drive is to the bottom bracket. Yours doesn't so the drive goes to the rear wheel. I solved the problem by extending the motormounts to meet at the bottom of the V and added extra U bolts to hold it there. This gave the bottom bracket the added stiffness it needed.
