it would depend on whither you are riding on a mountain bike or something that wont be doing stunts or a bmx or dmr. for mountain bike it probably will not matter whither it is big or not however for bmx or dmr it would be a good idea to have a smaller one as when at skate parks eg. you where going to drop into a bowl that is quite steep if you have a big on then the chances are it is going to hit the coping (top of edge) and maybe fall off. also if you are thinking of getting a smaller sprocket you will need to get a smaller cassette but don't guess how big the cassette should be for a sprocket just take it to a bike shop and they should be able to tell you. for a smaller sprocket i would recommend a 25t to 30t,, the 25t will have to have about an 8 or 9 tooth cassette. hope all of this helps took me a while to type out anyway :P!!

The dimensions of the tire is written on the sidewall of the tire. Make a note of these, then just buy an inner tube with the same dimension. You can go a bit narrower than recommended but the wheel diameter needs to be of the right size.

There is no reason not to ride a bike if you are heavy. However, make certain that you do not exceed the weight limits of the bike. Special heavy duty bikes may be a solution to the problem.

frame tubes are constructed from solid blocks of steel that are pierced and "drawn" into tubes through several stages. These are usually superior to seamed tubes, which are made by drawing flat steel strip stock, wrapping it into a tube, and welding it together along the length of the tube. Seamless tubes may then be further manipulated to increase their strength and decrease their weight by butting, or altering the thickness of the tube walls. Butting involves increasing the thickness of the walls at the joints, or ends of the tube, where the most stress is delivered, and thinning the walls at the center of the tube, where there is relatively little stress. Butted tubing also improves the resiliency of the frame. Butted tubes may be single-butted, with one end thicker; double-butted, with both ends thicker than the center; triple-butted, with different thicknesses at either end; and quad-butted, similar to a triple, but with the center thinning towards the middle. Constant thickness tubes, however, are also appropriate for certain bikes.

The tubes are assembled into a frame by hand-brazing or welding by machine, the former being a more labor-intensive process and therefore more expensive. Composites may be joined with strong glue or plastic binders. The components are generally manufactured by machine and may be attached to the frame by hand or machine. Final adjustments are made by skilled bicycle builders.

Really depends on what kind of bike you're looking at. A nice road bike can be 16 lbs, while a DH MTB can be 40 lbs.

The parts to build a bare-boned fixed gear you need:

1. A bicycle frame with non-vertical rear drop outs. Google "vertical drop outs" and then "horizontal drop outs." Horizontal dropouts are necessary to tension a chain.

2. A rear wheel with a track hub. These are threaded so that a special fixed gear cog threads on, and then a lock ring threads on in the opposite direction to keep the cog from coming undone while you are riding.

3. A cog and lock ring as described above

4. A bottom bracket and/or crank which will allow you to make a straight chain line from the cog to the front chain ring. This is important both for efficiency and safety reasons. By moving the chain ring closer/farther away from the bottom bracket it may be possible to make the chain go in a straight line from the cog to the chain ring. However, it may also be necessary to get a shorter bottom bracket spindle to bring the cranks and chain ring closer to the frame.

5. The other parts. Namely, a seat, chain, chain rings, seat post, stem, headset, handlebars, pedals, cranks, front wheel, inner tubes, tires, etc.

Riding without brakes is unnecessarily hard on your knees and I'd recommend against it. AND MAKE SURE YOUR LOCK RING IS TIGHTENED DOWN!

Tour de France

1) undo wheel nuts 2) hook chain tensioner onto wheel axle and over open end of drop-out 3) tighten chain tensioner until chain tension is OK, spin crank and check for tight spots 4) put wheel nut back and tighten them 5) spin crank and check for tight spots

By law, it is legally required to have lights on bicycles in almost every state in America. These states include Seattle, Massachusetts, and others. Contact the state department in one's area to see if it is required.

If you sit inside the wheel it's a Monowheel, if you sit on top it's a unicycle.

Depends on what you want from it. Single speed bikes are as a rule very robust, and the drivetrain components tends to last a long time. They also tend to be fairly clean-looking, with a minimum of parts cluttering up the frame. With that said, being limited to only one gear can be quite restricting if you're riding in a hilly area for instance. It'll be heavy uphill and you can't get more speed downhill by pedalling.

This question is covered by the Road Traffic Act. If a cyclist is seen by a member of the police riding on the pavement the could incur and £30 Fixed Penalty Notice.

Another point to note, cycles also must have lights in the hours of darkness, again failure to abide by this could result in a £30 FPN.

If the fines go unpaid, a summons will be issued for the rider to attend Mags court.

I am looking for one too. This is all I found, I don't know the name of the bike. It might be custom made?

Check that bits that are supposed to stay on are firmly attached, that bits that are supposed to move actually does that freely, that the chain is reasonably clean and lubed, that brake/shifter wires aren't frayed, that tires are well inflated and doesn't show signs of cracking.

Bottoming out means that the suspension has compressed as far as it can, and usually it doesn't mean that much. Suspension parts frequently have a rubber block that the mechanics fetch up against at full compression.

But it will mean a harder landing that may either damage the bike or the rider.

Depends on the type. Quill-type stems have an expander bolt pointing towards the fork which regulates height and alignment, then there's a pinch bolt which holds the handle bar in place.

Aheadset type stems have pinch bolts at the back which locks them to the steerer tube and faceplate bolts at the front which holds the handle bar in place. Then there's a top cap that's used to set headset bearing preload.

The cost of a road bicycle can vary depending on the type of bike, the quality, and the features that you want. However, you can expect to pay anywhere from $500 to $5,000 for a decent road bicycle. In this article, we will break down the cost of a road bicycle and help you decide what is the best option for you.

It depends. If it is just a bicycle that isn't very expensive, or has a long warranty on it, then it doesn't really need insurance, mostly because there are little to no bike accidents where people are killed, and bicycles aren't all that expensive. If it is a very expensive bike (over $1,000 or more), then insurance wouldn't be a bad idea, but only if you ride the bike a lot, or if it is something very important to you. Otherwise, bicycles shouldn't have to have insurance - there's just no need for it.

The actual riding isn't any more dangerous, but if you fall on a road you might get run over by a car, which wouldn't happen if you fell on a footpath. Regardless of where you ride, bicycling is generally speaking a very safe activity.

Motorized bicylces can be bought in a few places. They can be bought at stores that specialize in bikes such as Motorized Bicycle Canada or Zoombicycles, as well as at regular stores like Walmart. They can also bought on ebay, kijiji and craigslist.

probably in taiwan where most bikes are made
