    Bought a used bike tonight. Need help!

    I'm early on in my plan to start exercising more. I've been walking, but wanted to change it up a bit. I've done minimal research on bikes and found some on craigslist to look into. I just recently had my third child, and my oldest is 8. We have a bike trailer for the middle one and so far, haven't been able to take the youngest out.

    I ended up getting a Trek Navigator 200. The clincher is... I don't know what year and I don't know the frame size. It feels maybe a little bit big for me. It's a step-thru style and it's gray and white with red accents. The bike itself is in pretty good shape, and I feel good about that. I just would like to know the year. I've looked online and can't figure out which year it is. He said he got it 3-5 years ago. So, that doesn't narrow it down too much. In his ad, he said it has a 15 inch frame, but I don't find that size listed on any of the trek websites. Can anyone help me with this?? It has a plastic cover on the outside of the sprocket that is broken and I'd like to replace it. Any idea how difficult that is?

    Thanks for any information.

    Ps-My riding will be in the neighborhood and some basica bike paths

    Above link shows which years that bike was made. Compare the years to yours. Note the differences in front forks over the years. I ddin't see a 15" either, but did see 14.5" That size is measured from center of the crank to bottom of seat post [ the part of the frame ], not the seat itself. You say it is too big ?? Have you lowered the seat all the way down ? I suggest, get someone to hold the bike upright for you, , adjust the seat to where when sitting on it, & one pedal is on the bottom of the crank, & that leg is bent a little at the knee. The handlebars are pretty high, by design, & that may be why you are thinking it is too big. A pix of it would help, too.
    The plastic piece is best found at a bike shop. OR, use a velcro strap to tie your pants cuffs out of the way.

    The year doesn't actually matter--it's fine if you want to know out of curiosity, but knowing won't make it easier or harder to find parts.
    As estaban said, you can measure the frame yourself, from the center of the bottom bracket (the place where the pedal crankarms attach, at the bottom of the frame) to the top of the seat tube. A 14.5- or 15-inch bike is really tiny--my wife is 5'1", and she rides a 17--so if it's that size, I'd be surprised if it's too big for you.
    I'm not sure what you mean by "plastic cover on the outside of the sprocket"--is it the plastic guard between your right foot and the chainring? That isn't necessary, and none of my bikes have one, so I'm not sure how they're attached. If you want to replace it and you're lucky, you'll be able to unscrew the bolts (probably with an allen wrench, which you'll have to buy for a couple of dollars) and just bolt on a new one. If you're unlucky, it will be fastened in some intricate way involving removal of the crankarm or pedal, but you should be able to tell by looking at it carefully. Really, though, it's OK to ride without it.
    Here's a useful tip: Take the bike to a bike shop (a real one, not a department store) and tell them what you've told us. If you ask them for a tune-up or something, of course you'll have to pay for that. But if you tell them you're a new cyclist and you'd like a tire patch kit, a spare tube and a set of tire levers (all of which you'll need eventually anyway, along with a pump), they'll show you how to pick them out. Then you're officially a customer, and you can say, "You know, I'd like to replace this plastic thing, too. Can you get me one of those?" They'll either say yes and give you a price or tell you it's unnecessary, and when it comes in, you can say, "Do I just unscrew these bolts to put it on?"
    Of course if they do any work for you, you should expect to pay. But if you're a customer buying parts, it's perfectly acceptable to ask for advice.

    Thank you for your input. I will try to add a photo and see if that helps. My mom kept telling me that chain guard apparatus was unnecessary, but I kinda felt safer with it there. Silly, I know!!

    I will have to go look at the bike. When I first rode it, the seat was all the way down and I couldn't fully extend my legs when pedaling. I'm sure it will take some adjustments to get it right. My older brother has been working at Mt. bike shops for years and I'm sure he can help me. I just got worried that maybe i'd made a bad decision about the bike! I hope not, as I'm very much looking forward to riding it!

    I had searched the bikepedia lists before I purchased it, but couldn't find it on the lists. I will do as was suggested and look at the forks and see if that will help me. I'll also try to figure out what size it is. The guy I bought it from said he rode it and he is 5' 10", but that it would totally fit me. I hope so. I will keep looking into it!

    Thanks so much!

    Summer

    It can take awhile to get used to a new bike, especially if you haven't ridden in a long time. Get it adjusted in a comfortable position for you, & ride , ride, ride. Nothing anyone can say on here will help you more than your getting on the bike & riding. GOOD LUCK !

    have you tried looking for a serial number? I had a Trek and it was near the bottom bracket.
    Find the serial number, call Trek, they should be able to help
