bmx biking

I want to ride dirt trails and some street riding. I now have a mountain bike thats around 20 inch top tube and it has 29 inch wheels. I want something a little smaller that i can do tricks with. I’m 15 y/o and 6 foot. Should I get a bmx bike or stick with a mountain bike?

If you will be doing jumps and street, go with a bmx bike. Try to get on a bike with a 21" top tube, and as much chromo as you can afford.

I was biking i did a 180 off a box and i messed up and all my weight went to my left leg and i landed awkward. I had probobly one of the worst pains in my life. Its been a couple of days now and when i walk it hurt a little and if i try to skretch my leg it hurts right under the knee.

Why ask complete strangers via the Internet? If anyone here gives incorrect medical advice, they could be held responsible – LAWSUIT! Don’t you or your parents have a doctor?

I’m at beginning bmx and I just wanted to know what is a good weight range for a bike to be good for tricks.Like wheelies and manuals and etc.Best answer gets 10 points.

For a beginner 26lbs and lighter is recommendable.
20 – 24 would be ideal (I would save the crazy light stuff for a few years down the road)
You should try to aim for quality parts though.

Say you get a 15lbs bike with plastic, aluminum, and carbon fiber. In this case the bike would be outrageously expensive, and very weak. On the other hand if you go with a 26lbs complete bike, chances are you will be working with something just as weak.

Try as hard as you can to get a bike that has:

Chromo – frame fork bars axles and cranks

Micro drive train – 25 to 9

If you buy a bike that qualifies those specifications, you should be in good shape.
