Really the only thing that will truly hinder progression is not practicing. You can likely learn just about any trick on most setups, some things will be easier on a shorter bike and some things will be easier on a long bike. There really isn't an ideal setup, there will be pros and cons either way.

I am over 6 feet tall and have ridden very short bikes (1999 Hoffman EP, for example), long bikes like my current setup and everything in between. Progression happened on every bike whether it was short or long.

And there definitely are people riding flat on long bikes. An obvious example is Matthias Dandois, he currently rides with a TT of 21" .

Lol! How could I forget to mention Trevor Meyer! He has always been one to ride a long bike along with tall/wide bars.

I think you bring up a really good point here about riding long bike vs not riding... I am trying to build a new set up though so I just want something optimal. will def push on in the meantime.

I think it's imperative that we start an official Height / Bike / Frame database for
beginners looking for information on what size frame they should get to even someone
who thinks they might be riding the wrong frame. Or even someone looking for something
new.


In my opinion, people put waaay too much emphasis on top tube length. Not only is rear
end length just as important..but wheelbase is the most important thing on a flatland bike.


RULES -
NO GUESSING
ONLY ACTUAL DATA ALLOWED
THANKS!

1) Post your height
2) Your brand and model of frame
3) Your top tube length(s)
4) Your rear end length(s)
5) Your wheelbase (or wheelbases)


You can also add other information like whether you ride a zero offset fork or offset, crank length, stem length, etc. Comments on whether the bike feels cramped or spacious are important too. Any vital information.

This information is vital for people. Especially beginners. It's one thing to read about something. It's another to see what people actually use in real life according to their height and/or weight. This could help someone new from buying the wrong frame and/or wasting money / having to go through the process of selling a frame they hate to get another one.

I'll go first

Me -
Just over 5' 8" tall
130-135 pounds depending on the time of year
Lanky build (think caucasian version of Takahiro Ikeda)

2013 St. Martin Ten

17.9" top tube
12.1" Rear
30.5" Wheelbase
125mm Profile cranks
Zero offset forks

First off - Very few St. Martin frames are the actual length they are advertised as. That's just a fact. My friend Wes and I have owned just about every St. Martin frame ever made at one point or another. We have both meticulously measured them and most of them are shorter than advertised. The 17.9" top tube Ten by St. Martin is actually 17 5/8". MUCH shorter than 17.9". Keep this in mind as we go forward.

Feels cramped up front. Awesome for Hang Five type tricks. VERY squirrely for whiplash / front wheel tricks because the frame is very short and not very stable..so it doesn't work very well as a counter balance. You have to compensate with your body. Also, with light tires like KHE Mac 1's, the front wheel can unintentionally hop during Fire Hydrant type tricks. It just seems to have no anchor. A heavier set of tires and/or pegs on each end of this bike would do it justice, I think.

You need short cranks on this frame. Otherwise, they're just ridiculously in the way.

Overall, I think this frame would be PERFECT for someone between 5' 1" and 5' 6". Especially if you have short limbs and not monkey arms like I do.


===============================


2013 St. Martin Ten

18.8" top tube
12.1" rear
31.5" Wheelbase
145mm Profile cranks
Zero offset forks

Again, this St. Martin frame is actually 18 5/8"...not 18.8 as advertised.

Very comfortable up front. You can use a 26mm stem or 40-45mm stem and still feel comfortable on this bike. After riding it for a long time with a 28mm stem, I switched to a 35mm Colony Exon stem and it made the bike feel perfect for me. An inch doesn't sound like much..but the handling between this frame and the 17.9 Ten listed above is NIGHT and DAY. Frame works excellent as a counter balance and I'd say it's perfect for anyone between 5' 5" and 5' 10" tall. My only complaint is that I wish the frame was actually 18.8" because I grew up riding a frame that had a top tube which was almost exactly that size.

==================================

2013 St. Martin Voodoo

19.3" top tube
12.1" rear
32" wheelbase
125mm cranks
zero offset fork

Another St. Martin top tube scandal. I measured this one right away. From the Gyro tab holes to the center of the seat tube is 19 1/4". Not 19.3 as advertised. Close enough, though.

I literally just built this bike yesterday. Generally, a 19.3" top tube would be a deal breaker for me because that usually means a longer rear end. However, not in this case. The rear end is still only 12.1" which keeps the wheelbase length down while giving you TONS of room up front. As of right now, I'm running a 35mm stem on it. I don't have the experience on it to get into great detail..but I can tell you this - If I wasn't old school and didn't still use the top tube for tricks, the bike would be too long for me..and probably anyone around 5' 8"..unless you like a LOT of room. However, I still launch decades from the top tube and it feels amazing. I love having the space up front with a super short rear end. When I have more experience with this bike, I will come back and edit this to add more information.


I've added photos of each frame / rig in order of listing below.
Great thread and info here. I'm 6'2 195. My 19.5 Ares AFX tt feels plenty long but with a 12.6 CS my heel hits the back peg . I'm just getting back into bmx and flatland for the first time since about 1988. I also have a 21 inch tt street bike with 13 inch cs, a Fly Omega, which feels plenty roomy but way too long for flatland.  As I do more front and back wheel tricks on my Ares I should get a better idea of my ideal bike dimensions. Incidentally I already broke the Ares stem bolt so I'm replacing it with an s&m flatland stem. Also I'm swapping out the 27 inch wide Ares bars for 22 inc wide Bayou bars I scored on Offer Up. I also don't like the Ares pedals so I'm swapping them for some Odyssey Grandstand V2s since my feet are big and need more surface contact....

Hey guys,


This is an awesome thread. I'm currently in the market for a new frame and am wondering how much longer I should go.



Height: 5'11
Weight: 180lbs


Current Setup:


ST. Martin Eiffel Frame


TT: 18.2


I'm just getting back into flat after a long hiatus and have noticed that I just don't feel like I have enough room at times. I've been eyeing the Autum Blitz No Touch Frame TT 18.7


Before I shelve out any money I was wondering is .5' would actually make a difference? Also what happened to all the style??? Everything just look like regular street bikes now.

Hello classytouch, nice to have you here!
Yeah, the street look... I don't like it so much but almost all riders follow this trend at the moment. This is why frames like the Autum are rare.About the TT length: 0.5" can feel a lot! I would not choose more difference (although in the end you can get used to anything).
But it depends a lot on the overall geometry! When you have a longer TT with HT and ST angle being the same, your seat is more far away from the handlebar (as long as you do not compensate with your seat position (as long as you don't use pivotal seats)). But you could have the same effect for example with a lower ST angle...
For backwheel tricks the wheelbase is very imortant for your overall feeling. So you need to consider this parameter and it is influenced by the CS length, ST angle, HT angle and TT length.
This may help to estimate how much different another frame might feel.

I am on a short setup pretty much at 18.75 frame length(Motel Works)
6.75 bar height etc(Ryal Goods-Dylan Worsley bars) etc etc


It is really how comfortable you are with your setup in your
setting up the bike and i feel comfortable with my setup!

Hey DaddyCool,


I really appreciate your taking time to answer my question! I've been riding for some time but for some reason never truly understood the mathematics of frames with respect to rider and fit. I know some of it is trial and error but I also want to get something i'll be really happy with...Something with some STYLE too! I think I'm going to give the Autum a shot..... Also... Where can one get an Ares? It seems Flatlandfuel doesn't have as many frame options as they used to have.

I was checking out Alejo Marques' channel on youtube. He rated the Autum his number one frame currently on Flatland Fuel. He also liked the Heresy, based on his riding it...incidentally. at 6 feet tall he said anything over 20tt is uncomfortable for him for flatland.  I think what we have to keep in mind is we really don't pedal that much; it seems like the distance between peg, and distance to get around the bike matters. For me I'm riding 19.5 tt with 8 inch bars. I'm switching to 9 inch bars but I think my next frame will be 19.3 or even 19...

Those are two good frames and at 6 foot or about 6'1 as the 19.5
is about right length and you do not have to be a Trevor Meyer or
a Kevin Jones,who are both tall,to ride a 19.5 frame. i have said it
is what you are comfortable on and I am 5'8 and just ride a 18.75
frame.OSG,who i ride with rides a Hoffman Strowler frame..Kevin
Jones second design effort..The Big Daddy Frame was introduced
in the early 1990's. He is a big guy at 6'2 and he loves the frame
as it is light and 74.5HA(head angle).It comes in 18.75 and 19.75
frame length.Removanle brake mounts and cable guides,Mid BB,
integrated  headtube with removable detangler tabs.


It is a really steady frame for the larger flat riders and is like
around $250.00 and you can still get them and just look around!
The thing as they are very steady and will take tall and heavy
riders and still are light!
