Over the years I have had so many bikes that just break down!!! What a drag you want a nice bike you get it and then two weeks later it breaks down and you are out of a perfectly good bike!!! Whats the answer folks any guesses? I have found that regular maintence is a very good thing! Yep just keep a good service record so to speak and keep it oiled as well as in check which means all  components that is like gears brakes and any parts that need something like a squirt of oil! There is one extra tidbit you may find juicy which is every time I bought a bike ready put together that is when the troubles began. I since then bought one and put it together my self and what in tarnations not a problem was there!!! I was so proud I put the whole thing together myself!! There is also a quick fix for potential flats that I know about which was to protect the tube I just added a nice rubber strip to the inside of the rim to keep the rim from wearing on the tube so much because I discovered this can really cause flats!!! Suddenly there were no more flats and in fact I did not even have to go get heavy tubes the tires really were thick enough!! You would be really surprised at how practical approach that is to keep from getting flats also!! This one is a winner!!!Hahahahaha yep!!!!

Good luck on all your bike stuff!!
