If you have 56 bikes & 128 wheels: How many tricyles & how many bicyles?
104029
40 bicycles and 16 tricycles. do a system of equations using 3x+2y=128 and x+y=56. where x is the number of tricycles and y is the number of bicycles.

A good site is Weight Weenies.  Shows the weight of many bicycle parts.

If you ride a lot you could handle a 100-125, maybe even a newer model 150. The older bikes are heavier, so you have to drop down in cc's. A lot of grown women ride 150's and they are 110/120 lbs at your height. It is also important as to how agressive and mature you are. If you and your parents think you'll do some risky stuff, you're better off with the smaller bike because it's lighter if something bad happens, and it goes slower.

Get thee to your local bike shop...  they will help you find the right wheels to help you ride safe!

this is the equation \n\n2x + 3y = 19\n\nwhere 'x' is the no. of bicycles\nand 'y' is the no. of tricycles.\nJus substitute any1 and u'll get the other.

Rim compatibility should be no problem as long as rim and hub have the same number of holes.\n\nDepending on the age of your hubs,  600 hubs were part of the Ultegra gruppo. If these are 600/Ultegra hubs then it is most likely you can use an 8 or 9 gear cassette on it no problem... but it is always a good idea to check first.\n\nIf your hubs are from the "early days", the rear is likely outfitted for a freewheel. I know an 8 gear freewheel is available but am not sure about a 9. In either case you'll need to make sure that an axle of the correct length can be procured.

I've seen a 450 cc, and I thought that was big, but I recently came across a 500 cc as well!  I haven't seen any bigger than that.  I tried my friend's 450 cc, but I don't like them.

My sister and i have Ocean Pacific Cruisers they are 26 in and we bought them at sams club for 80 dollars some are 50 they are very good bikes maybe the best cruisers

From your current location take 120 steps north then turn left & take 1000 steps then turn north east & take 55 steps & if you find a bike shop. It would be a spot on guess. lol

I agree with an earlier answer in that you do not want a spoke count that low if you are going to use disc brakes.  Discs add a great deal more force on the spokes.  In fact, it is recommended that disc specific wheels be laced a certain way, and it is much different than a "regular" bike wheel will be laced.  By "regular" I am referring to a wheel which is laced for use with V-brakes.\n\nAlso, typically, because you are talking about a special lacing, you typically will pay a premium for it.  Be prepared to pay at LEAST over $100.00 per wheel.\n\nCheck out www.spinlitecycling.com, and www.wheelworld.com

Technically your bike has 21 gears--the number of rings on the front times the number of rings on your cassette in the back.  However, you don't really have 21 usable different gears.  This is because:\n\n1) Depending on how many teeth are on your chainrings (front rings, you have 3) and your cassette (7 rings on back), you may have some gears that repeat.  It is all about the ratio between the front ring and the back ring the chain is on.  For example, let's say your middle front ring has 38 teeth and one of the rings on your cassette in the back has 19 teeth, you have a ratio of 2 to 1 when your chain is on these two rings.  If your smallest ring in the front is 28 teeth and your smallest ring in the back is 14, you again have a ratio of 2 to 1, so these gears are actually the same.  \n\n2) There are also certain gears you should not use.  You should avoid cross-chaining--being in smallest ring in front (closest to the bike, on the inside) and the smallest ring in back (farthest away from the bike) or largest in front (farthest away from bike) and largest in back (closest to the bike).  Either of these gears, or close to them, puts a lot of stress on your chain because it torques it sideways.  This will cause additional wear on the chain and shorten the life of it.  Most bikes will allow you to do this because the chain is put at a length to allow for it, but it will also likely cause your chain to rub somewhere and also possibly make your bike not stay in gear very well.  \n\nHowever, these days, rather than multiplying the number of front and back rings to get speeds, bikes are now often referred to by the number of rings on the chain ring and cassette separately.  You ride a 3 by 7 (3x7).  A double road bike with a 10 speed cassette (typical of today's high end road bike) is a 2x10.  A more touring oriented road bike often has a triple chainring and is likely to be a 3x9 or 3x10.  A fairly typical mountain bike is a 3x9, but there are a lot of 2x9 or 3x8s out there too.

18 speeds are out-dated. Even your junk bikes from Walmart are now at least 21 speed. You did'nt say what your "expensive" is. Figure on spending at least $250 on a new entry level bike. You can try craigslist and/ or ebay for used bikes. But know what you're buying. Make sure it's a name brand like Trek or GT. Your department store bikes are all junk as far as quality goes. Unless you're 8 years old and will trash the bike in two months anyway. BTW, a good way to tell if the bike is half way decent is to see if it has quick release levers on BOTH front and rear wheels.

ok biker bike, here we go.\n\nacc.= g = 9.8 m/s2, (any object moving in air will have this acc. or retardation)\n\nb) we apply formula\ns=ut + 1/2at^2\nu=20\nt=4\ns=20*4 + 1/2 *9.8 *4*4\n  =158.4 m\n\nc) v=u + at\n  therefore, t= v-u/a\n                   =50-20/9.8\n                   =3 seconds (approx)

u dont need the 6 in this question because all the tyres travel the same amount. (its juss there 2 throw u)\nso then all we have to do is go:\n\n 16000(distance travelled) / (tht means divide)8 (amount of wheels)= 2000 (basic division)

You need metric tools and bicycle parts.  Then, you need too follow the instructions that came with the bike.

Finding the individual cog may prove to be tough. You can, however, buy a complete freewheel with a 34 tooth cog on it from Harris Cyclery.\n\nhttp://www.sheldonbrown.com/harris/freewheels.html#7
