I am 15 and i am getting into bmx but my bike has been giving me a bad lower back pain after and while riding. I know it isnt muscle pain because go to the gym and i know how that feels like and i know it isnt because i need more muscle becuase i am fairly fit. I believe that i need higher bars because i am around 175 cm tall and my bars are 6" what bar height do you recommend ?

6” bars? My back would be broken, not sore.

Don’t put 25.4 bars in a 22.2 stem.

Where are you measuring your bars from? In order for us to know where you are at, we need an industry standard measurement (i.e. center of the stem clamp area to the center of the grips, straight up. If that's too difficult to get, you can do the top of the stem clamp area of the bars to the top of the handlebars where the grips mount.

Same height as me, when i was your age i rode odyssey civilian bars 7.75 rise

I recommend getting some 9 rise or 9.25 rise bars it will be a game changer for you

I agree with the 9.5" bars however; if you are using a front load stem I would say 10".

Shoulder width/TT length/bottom bracket height, top load stem. All this play an effect on what bar height you should run.

But regardless 8.75-9.25 would probably be solid. Depending on top load or front load.

stretching before riding will help you more than bigger bars

I measured from the stem up to the tallest point of the bars so pracktickly the horizontal part of the bigger tube(2 piece bars)

I'd suggest 8.5 to 9" or so, taller bars are overrated (though 6" seems really small unless have a tiny starter bike and the TT is also too short). An inch or so on the bars doesn't really change your crouch all that much, it mostly just changes your leverage. If the height from your pedals to grips is 25" instead of 24", you're still bending over by more than half your height.

When you hit the gym, forget about your arms and focus on lower back. Dead lifts, standing presses, hang clean, reverse sit ups, anything that hits the lower back. After a few weeks, you'll forget what back pain felt like.

Remember when you could ride all day and not be sore for a week?

If my pedals are horizontal is around 27"
And if my pedlas are vertical it is around 16

I meant the straight vertical dimension from pedals when horizontal to the height of the bars. 27 sounds high, you probably measured at an angle? Mine's 21" measured vertically and I'm about 5'9", but I run em low and have a high BB for flat. I think most riders run around 23" to 24" or so.

My point was that an inch doesn't really change your posture much, so back pain isn't caused or cured by a slight change in bar height (unless you actually have back issues off the bike). Bar height mostly affects leverage, which can reduce strain a bit, but having a stronger back is always a better thing.

Agreed on the 8"-9" range.

I’d say 8.5” to 9” will be sweet. I used to swear by 10” bars, ran them for a couple of years. Moved to 9” bars a couple months ago and I never want to go back to tall bars now. I’m 5’, 7” on a 19.69” TT.
