Hey!! So a few years ago, an old man gave me this bmx but it was very old so me and my dad decided to fix it. The seat is new and so are the tires. The rest is all original, could someone help me? I have never seen this type of frame tho, it has an "X" on it, as you can see

We often get questions on bicycles.stackexchange about identifying a bicycles manufacturer, model, make, and year.  Often these questions are downvoted or closed -- usually with a comment attached to them that it's not necessary to know the exact model/make/year of a bicycle if you want to fix, repair, or ride your bike. Why should owners not care about the model/make/year of their bicycle? Especially when it comes to less expensive bikes (aka BSOs) and BMX bicycles? This is intended as a canonical question that we can point closed questions to. Also see      (generally not helpful for identifying a brand/model)

I have an old Huffy from my uncle that he bought at around the 90s and I'm thinking of restoring it and maybe upgrade some of the parts. But Huffy doesn't seem to have any much information for bikes over 10yrs old. Here's a .  Obviously, I need to strip the paint of rust that's accumulated and clean it. But I'd like to know what I can do to see if any current generation parts I could use. I'm planning to convert this into a commuter or maybe a road bike (not to be raced). I would guess that I need to replace the whole drivetrain. Maybe fit in 700c wheels or something similar? Brakes need replacing as well, since it used old caliper brakes, I'm guessing that I can use some modern brakes? I suppose the headtube needs some work as well. Basically, I'm only planning to keep the frame and the fork.  Hoping somebody could help.

I am learning to replace chain and freewheel (So far so good). After I put new freewheel and new chain on, the chain are too close to each other at the back now (as you can see in the photo).    I think I need to adjust rear derailleur, is it right? Or maybe the chain wasn't installed correctly ( I cycled around and think chain install seems not too bad).

I'm a biking amateur, but I've been wanting to upgrade and get more serious.  Just recently, I was gifted a pretty new bike and I'm wanting to figure out how BSO it is so I can either upgrade it or get rid of it get a new, nicer bike.  What should I check to tell how much of this bike is cheap BSO material and how much will last?  I'd really like a part-by-part list so I can replace them or decide if it's not worth it.

Earlier this month I had a issue with a broken axle.  It was the original that was sold with the bike and lasted around 5,000 miles.  I went to my LBS and bought a new axle (unbranded, labeled, etc, paid $13, came with cones, spacers, and hardware).  I did the install myself and had everything adjusted nicely.  The next time I rode it was on my commute to work, but I didn't get 4 miles into it when I found that I bent the axle.    I took the wheel to the shop but they wouldn't do anything about it since I didn't have them do the work.  However, I figured this was a fluke and asked them for a new axle and to true the wheel.  Once again I did the install of the axle and only got 15 miles out of it this time before bending it.  Before I got home I felt the wheel get stiff, but it stayed true.  The question is what will be a cause of bending 2 axles in 20 miles?    I think the guy at the shop said it was a cro-moly axle (while talking to another person today at the shop, these may not be), and he couldn't believe that I bent it.  If so, where would such an axle fall in the quality hierarchy?  Or is my hub toast?  While the wheel was being repaired, I swapped to a new original wheel for about 2 weeks.  I have not had any issues with it, but I wanted to keep it as new as possible.   Reading other questions I saw a comment that said not to use a hub where the bearing was catching.  I did have one in this wheel but I figured since it is a cheap wheel I would just burn it up and move on to a better one.  Besides, it has lasted 5k miles without issue to this point.  The bike in question is a 2008 Schwinn High Timber with Joytech freewheel hubs.  I do use a trailer with this bike using a Burley axle hitch.  While I had the hitch installed on both axles I bent, I did not have either trailer hooked up to them.  Something I would like to note is that when I removed the first bent axle (axle #2) that the cones on it had a wavy bearing track.  I didn't think too much of it, and I put them on axle #3.  Only having a few miles on them shouldn't have made a difference?

I recently bought a new bike. It is a Scott bike with disc brakes. The bike went in for it's service and now it has problems braking. As soon as I pull the brake leavers the front brakes makes a loud squeaking noise. The front brake disc is a blueish color from trying to brake.   The back brake works perfectly. I took it back to the people who serviced it, and they were unable to solve the problem. Do you know what the problem could bee and how to correct it?

When it comes to fixing bikes, i'm not to crash-hot. I can clean grime, oil the chain and put it back on if it falls off. However, when it comes to the inner tubes I usually rely on someone else to get me another tube and put it on for me (I can put them on, but in that sense I'm too lazy). So, today, when I went to pump up the tyres I found they had a puncture and I would prefer to change them as I haven't ridden this bike in a LONG time, only I'm not sure if there has to be a certain size tube. Help? Please? :)

Just bought my first bike and it was put together by the store. I was wondering if this little cable/wire is okay, it's hitting my pedal every time I’m riding. It doesn’t really bother me, but I don’t want it to end up messing something up really bad. Help please new bike owner

I have recently purchased a hybrid bike with suspension (not sure if that is relevant to this question). It came with two pieces of plastic. Any ideas what they may be for?

My daughter has sparkle and glitz 12 inch bike with stabilizers (training wheels). Since we purchased the bike every now and again the back wheel keeps spinning when she is pedaling. This seems to happen more when there is a bit of an incline.  Any suggestions what problem could be?

If I need to sit more upright on an old Fuji road bike, can I turn the drop handlebars upright and reversed so that they come up and then point to the rear?  I haven't seen anything on the net from anyone who has done that.

I just bought a new MTB and am planning to change my previous MTB into a Road Bike.   How do I do it? What kind of parts do I need to change or add or remove?  I am not looking to for a full conversion into specialised road bike. But like the answers are suggesting, I am looking for a bridge between commuter or road bike. My majors concerns to be met are:   Should be fast enough to compete with road racers over short distance Should be light as a road  Should be as close as possible in as cheap as possible.

I have a Lappierre Zesty 314  (2012). I'm running XT rear mech, an SLX front mech, my crank is XT, rear cassette is XT and XT chain. I went to the Forest of Dean and after the day was over I snapped my chain! I picked up a SRAM chain for my bike and now when I pedal hard it slips with a big bang. I have new Eastern Havens so my hub is fine. Can you help with any ideas to help me solve this? Shall I get a new rear cassette?

A few years ago, I've bought  (see edit) bike. At that time I was around 90 kgs and I didn't have any problems.  Today I'm around 120 kgs and I was considering (among other things) starting cycling again. Is this bike "good" enough to carry me? What should I expect? Any tips?  EDIT! Apparently, Drag have renamed some of their bikes in the last few years, so the above information is a bit wrong.  seems to be my bike. At first I didn't recognize much difference, but this one has suspension on the front which mine also has. Does this change anything

So I was doing a fairly simple model of a Glock hand gun. I had already applied a mirror modifier to the model, that I had so far (which was the grip). Then I applied the subdivision surface modifier. At the point where the mirrored part of the model and the "real" part of the model met it collapsed inside of itself. Bellow will be a picture of the model. I would really appreciate it if someone could tell me how to fix this so I can get back to working on my model. Also the picture is the bottom part of the grip, it may looks like two smaller grips, they are supposed to form one. But like I said it collapsed in on itself.  Thanks, Nova
