** This Is The BEST GEAR RATIO For BMX ** 

25/9. But I remember the old days with my 44/16. It was crazy going to the 36/13. But the 25/9 works for me just fine. If I ever break the sprocket, I’ll try a 28t.

Way back in the day my gear ratio was 43 / 15 . It made for a bmx dirt racing style drive back then & it was smooth , I just brong it over to bmx freestyle , made it simple to sit down & pedal up steep hills & you got more torque to go faster & this was back in the late 80s early 90s . People who rode my bike for the first time couldn’t Believe how much torque it had & how smooth peddling was & fast made going for big airs really easy & I needed all the help I could get because my bike was 40 pounds on the dot . Back then bikes were made out of 4130 Chrome Molly which made them very heavy .

Back in the day I ran 39 16 for a while , it was cool in tiny parks and spaces where acceleration mattered

My sweet spot for gear ratios is always 3.07 to 3.11. that's the number you get when you divide the amount of tooth on the sprocket with the tooth on the driver/freewheel.. i got a 28:9 ratio on my beater bike. And 43:14 on my mid school bike. For me, that ratio is just perfect. Fast enough, but not to heavy.

Awesome video! I’m strongly opinionated that 30/9 is my favorite because you can get so much speed with such minimal effort. Pretty sure Mark Webb was running a 22/8. I’ve always been interested in trying out that combination for the major clearance benefits.

You can’t talk about gear ratio without crank length. Here it is 27-9 with 175mm, 26-9 with 170mm, 25-9 with 165mm. 1 front sprocket tooth per 5mm crank length, when using a 9t driver. Makes a good rideable feel anyone can comfortably ride regardless of age or strength. This is the combo. Trust me.

32 mph on a 20" BMX is haulin' bro! I'm running 39/17 on a 24" cruiser (DK Sentry 24 from 2013). My last bike was 25/10 (2020 model DK Legend 26") Seems like the most common are: ☆ freestyle bikes are unually 25/10 ☆ racing bikes are usually 39/17 For casual riding around the neighborhood or commuting to work, I find both are comfortable and still have a bit of sprinting ability.

For me personally it comes down to how hard you wanna pedal and rear end length. I used to run 28 tooth but my wheel would sit far out of the drop out. If I took a link out it would be a little to close to slammed for me. My route was get a 26 tooth sprocket. I also have a 27 as well. 26 is perfect for me. Just a tad harder to pedal than a 25 but not as hard to pedal as 28. And it keeps my wheel center in the drop outs.

Is 28 9 harder to pedal then 44 16?, I like haveing fast high end speed but I'd like to lose some top speed to have an slightly easier pedal, I'm going to research 28 9 gearing. Even though it's 22 8, 25 9, 28 10, 30 11, 33 12, 36 13, 39 14, 44 16, grew up on 44 16, switched to 39 14, easier to pedal no top end speed. 36 13 was harder to pedal but had top speed. 30, 11 was hard to pedal prolly least favorite combo 30 11,. 32 14, felt great wasn't hard on the legs but wouldn't have fast top speed. I want to find a gear combo. That's not as top speed as 44 16 but slightly easier to pedal from complete stop then 4416. Rideing really fast like race bike is fine but it's sorta more loose control Wipeout around turns.

❤Extremely informative!

So I currently have a 20 inch bmx with a 25-9 gearing and 170mm cranks. I'm considering getting either a 27 or 28 tooth sprocket but I'm trying to get into bmx racing

EXCELLENT video...and very informative. Personally, I'm old school, and I mean OLD. My ride back in the mid 80s was a Revcore (remember those?) and I ran a 36 up front and either a 14 or 16 in the back. Top speed was important because I could outrun somebody chasing me on foot. So now, I am putting a retro 1986 GT Performer together for my son, and buying him another bike in the meantime, and this micro-drive thing really threw me off. Now I understand it all. Thank you!

I use 25t x 9t for my 24inch bike ❤

There used to be a bmx gear ratio calculator where you could put number of teeth of sprocket and teeth# of rear cog. And it would describe how easy and hard to pedal it was I'm description. I can't find that bmx gear calculator page anymore. It's only 1 that had description of how hard or ez pedaling was

33/12 equals 44/16. 53.63 ratio. It's the perfect blend between acceleration and top speed. Thst means it's balanced between easy and harder to pedal. Too easy means you have no top end speed. And hard pedal is to rough to basically put all your weight in 1 leg to get first pedal off to roll .

So which bb height do you recommend, keeping in mind that the Bike should be stable enough

Hey guys whats the best for low speed or freestyles?

I run 28-9 on 160mm cranks!

33-9 is my gear of choice, it's stiff as hell but sends you to the moon off half a crank

I’m running 28t - 9 but will be going to 30t - 9

My preference is 27/9 have been riding it for years now.

Harder the ratio the less slack you have in your freecoaster!

28/9 on 175mm cranks, wouldn't have it any other way 💯

Best modern day is 170mm crank, 25t front 9t rear.

36/16 is great for hillclimbing!

31/9 170 cranks but i ride mostly trails and thats my preferred ratio…but ive ran 28 and 33 also with same driver and tested both with 175 cranks and 170 i can seem to tell the difference between 2 teeth also can tell 5mm crank difference tests were done separately so wasnt making two changes at a time exaggerating the feeling.

Does anyone understand that a 44/16 is an almost identical gear ratio to a 25/9 they did it because of size.

30 /9 duh 175 cranks

So one of my bmx bikes has a 16t freewheel in the back and a 36t sprocket in the front and I feel like I’m pedaling a mountain bike in the first gear when I’m on it I hardly catch any speed and max out so quick. To easily fix the issue do u recommend that I buy a smaller freewheel like a 14t for the back? or a bigger sprocket like a 38t or 40t for the front? Any help would be appreciated! I’m just newer to this bike stuff and wanna do this the easiest cheapest way. I just want more momentum and speed per pedal rotation

When I was growing up BMX meant you were racing on a dirt track. The guy in this video looks like he's riding freestyle or flatland.

I like 28/9 but have considered 30/9 over the past few months.

25-9-170

Hi

I run 33 /9 but i think im gunna be goin up to 35 /9 on my new bike

30 9

Profile elite ?

43-16

33/10 great for trails and street

Race or freestyle, for the love of God, there is a difference!

33/9 165 cranks

I'm riding 30/11, but I want to step up a notch by going 30/10

I ride 30/11

44/16 is the best for rolling ratio... Just not good on clearance.

cassette 28-9, freecoaster 30-9. freecoasters pedal smoother and lighter 30-9 avoids the hamster wheel feeling with them, you might want cl;arify how gear ratios work or some poor bastard that does't know anything ends up with 25-16 setup because they didn't know they have to have a cassette for any of this to appy

28/12 *chefs kiss*

28/9 165 cranks. feel no difference from 25t
