always make sure the air inflation is up.... especially the rear tire.... otherwise the tire will turn on the rim.. and tear off the valve system.... that will end your riding for awhile... that is why I use the pressurize valve caps .. you can get them at harbor freight or ebay... very cheap on ebay from china... they are a INDICATOR.. to let you see if the air is down... for safety... some people are against them... but if you are too lazy to check your air or if you have kids who are too lazy... then they are good...
