Today I decided to nickname my new bike out of sheer boredom. I've decided to call it the Rotary for right now, just because the chain is somewhat loud when i start from a stop, but as i go faster it moves easier and get to this nice buzzing sound just like a rotary engine. Although, I'm sure that noise from the chain could be an issue, but I can't seem to figure it out, I've lubed it with the teflon chain lube and it still makes noise.
