I took it out for my first ride yesterday, was great. Had no issues
But I have 2 more questions for you, how much slack should the chain have (how loose/tight)? Also how tight should the rear axle bolt be? I recently took off my rear tire to fix a flat, now I can't figure out how tight the I should make the bolt. Do you have a bike similar to this? Could you take a close-up picture of your rear tire?
