Sturdy stabilisers to fit a 20" wheel BMX bike?
825585
I dont know where to get them (sorry) but I have seen motorcycles with stabilisers on, in use training people to controll big sports bikes. \nMaybe you could look in that direction ? call a few track race-day motorcycle  training schools and ask them if they know anything about them.\n\nWish I could help further.\n\nJust seen theese on eBay.... maybe a thought to look there ?

They dont sell to many complete race bikes on there but I suggest building yourself up a Saats or Standard frame.  I am actually riding a Standard right now but am going to go with an aluminum staats for this racing season.  If you really want a complete the only race bike they sell is a MCS.

I think you'll find most bars are tapered a little bit- they're beefier in the middle for more strength where the stem clamps on.\n\nWhat kind of riding are you doing?  The only caution about riser bars is that they make it more difficult to put weight over your front wheel as your are climbing.  So if you're a xc rider you may go with a shorter rise.\n\nYou could try getting an angled stem to use w/ your flat bar- they make stems w/ an adjustable angle also.

You made an excelent question, and often an overlooked factor when buying a bicycle.\n\nAs a rule of thumb never buy a serious bike at a departament store, always go to a local bike shop, where you will get great advise.\n\nThe most important measures when buying a bike are\n\n1.- Frame size. There should be 1 or 2 inches between your crotch and the top tube. A longer top tube will give you more stability.\n\n2.- Saddle height. Your leg should be slightly bent while sitting on the saddle and the pedal is at the lowest.\n\n3.- Handlebar Height/lenght. Depending on what you want to do, your handle bar could be 1 or 2 inches below the saddle (mostly MTB and race bikes) or even with the saddle ( touring ) - A short stem will gove you better handling.\n\n4.- Saddle. Once again it will be determined by your riding style, you should find the center of gravity for your riding\n\nThere are a lot of internet sites that could help you make a decision, I suggest you read more on the subject and most important, go to a local bike shop where you will get expert advice.

Go to your local bike shop and ask them to recommend a tire for you. You'll get a better answer there than you will here.

For light exercise I personally would not recommend a fully suspended moutain bike.    \n\nI purchased a Specialized Crossroads for my partner and she loves it.  It has a light duty front shock that's not heavy and a suspended seat post with a nice cushy seat.  If you are looking to pedal around the park with your family or run errands around town, I would recommend a bike like this.  I'm sure other brands have something comparable.  I believe this model is also in your price range.\n\nAs someone else said, go to your local bike shop.  Most of the time they are very helpful.  If you are as specific with them as you were here, they will show exactly what you need and explain the pros and cons of different brands and let you make up your mind.\n\nGood luck!

I found stabilisers were worse than not using them!\n\nThe most important thing is to make sure you have the right size bike! If your daughter can put her feet flat on the floor when the bike is still and she is sat on the saddle then you have the right size!\nOnce you have the right bike, you must make sure they wear at least a helmet for safety.\n\nNow find yourself a large area, like a park where she has plenty of room to wobble!\n\nGet your daughter to sit on the bike and just free wheel it a bit...... by this I mean get her to push the bike forward with her feet and then lift her feet off the floor so she can feel the balance of the bike. Once she can move the bike a few feet on her own without wobbling too much she can go on to stage 2.\nDepending on what foot is the most comfy, get her to put the pedal to the top and then rest her foot on it, with her other foot on the floor. When she is ready get her to push down on the pedal and feel the bike move forward.\nOnce she has mastered this she can then go to stage 3.\nDo as stage 2 then get her to quickly put her foot on the other pedal as it comes up................. with a lot of practice and determination she will master it very quickly.\n\nJust be prepared to nurse some cuts and bruises and maybe a little hurt pride!\nDon't push her, she will take her own time and her confidence will grow with each stage passed.\nIt took me a couple of hours to get both my boys riding bikes. It was a wonderful feeling seeing them acheive it.\n\nGood luck!

they are supposed to be, BMX bikes are designed for stunts and tricks,so they make them smaller and lighter

If you want a really cheap bmx, than go to your local walmart or kmart or target too.  but beware, alot of those bikes are heavy as shit and they are welded by machines, so when the welds are passed, they are turned up almost as hot as they can go, so that the machines can weld right over it as fast as possible, they ussually xray a few to make sure the welds are ok, but the truth is most bikes are ussually in the shape where they could fall apart at any second.  look into the walmart bikes, 9 different lawsuits on them.

I have made and ridden motorcycles for 20yrs and the biggest factors with tyre sizes are stabilty from centrifugal force. Bikes with small wheels are unstable at higher speeds, they are inherently closer to destruction because at the same speed a smaller tyre is revolving faster. Tyres are critical on bikes. As a bike leans in to a corner, the tyre, because of it's shape or profile, increases in contact surface to counteract the amount of force pushing the bike to the outside of the corner. These forces get to a certain point before the bike will slide and crash. Things that affect the performance of this are, heat in the tyre, weight vs power vs tyre size, tyre profile, diameter, motorcycle geometry.\nBasically you do not change wheels or tyre shapes on a bike unless u are prepared for the consequences. Harleys may put really big tyres on but they are not performance orientated. \nAlmost all bikes these days have a 120/70 17inch front and depending on power a 160-200/55 17inch rear. Most bikes pre-1988 ran 18inch(or bigger) tyres. The simple reason for this is stability vs steerablity. 17inch is the best compromise. If you are designing a bike, stick with these sizes and work on suspension, geometry and weight distribution as they are more changeable. cheers Neil

Hi, You can try either www.kitbag.co.uk, www.subside.co.uk or cheapest of all I think would be www.sport-e.com (I used the last of these to get mine for just £15!).

Obviously the bigger names like Yakima or Thule make racks for 5 or more bikes, but it is hard to say which is better...  depends on whether you are using a trailer hitch or a rear door mount.  Get thee to your local bike shop and check them both out.  Ride safe!

Get thee to your local bike shop.  Get fitted.  I have a KHS folding bike that I keep in the trunk of my car.  It is great to get around on and a little bit of exercise when necessary, but I wouldn't recommend it for long rides.  Ride safe!

Again, go and try a few out. You do want a certain amount of clearance while standing over the frame, mountain bike more than road bikes, but it's the saddle to handlebar size you want to be right for the correct reach as that is only adjustable by a tiny amount where as you can lift the saddle up and down by miles to get the right height.

Depends on what item your looking for.  To my knowledge there is a Tuff Block (spelled just that way) that manufactures BMX brake blocks, and also a Tuff Block (again spelled as such) that manufactures mats and flooring.  \n\nNot sure if either of these are what you're looking for, but hope it helps.\n\nStatic
