You want to create a End Of Ride Checklist. Here you can start with these 3 items you'll want to do after each and every ride.
1. Lube your Chain - You're instincts might tell you to LUBE your chain before you go for a ride but If you do this your chain will attract dirt and create problems with your ride.
2. Check Tire Pressure - You'll want to check this so if you do have a loss in tire pressure you're NOT surprised the next time you go to use it. Giving your bike a once over before you leave is a good idea too.
3. Clean Your Bike - Cleaning your bike will help the health of your bike. By cleaning your bike everyday you're looking it over and finding any potential problem before it becomes a bigger problem.
Follow these steps and you're sure to have a healthy happy bike ready for YOU!
