i bought my first bike about a week and a half ago. i was coming home from my first long ride which was about 20 miles away. on the way home i felt like my back tire was going out. like a flat feeling or just the back itself was drift along with the bike. i wasnt even going the speed limit because of this feeling and the wind that was hitting me. when i got home the tire was fine with no pressure loss or anything. i was kinda tired on the way home and the tire and the roads were hott too. i might have had my foot on the back brake. what should i check before i go out next any is everything OK? was my brake causing this too? all my other rides have been fine with no problems. thanks guys

 

Just check the wheel grab it and shake it to make sure the bearing is ok. See if there is any play in the wheel. If the wheel is solid and the tire is full it's probably just you. Definitely keep your foot off the brake unless you actuall need to use it though.
