BMX - BMX vs trials bikes

i don't usually frequent this forum so i'm sorry if it's been discussed here before... i've become somewhat interested in trials riding and other than the newest, most extreme trials bikes, i'm wondering what the differences are between a BMX bike and a 20" trials bike (i know there are 24 and 26" trials bikes). i know the stem is longer and the bars are different, and the rear wheel seems to always look beefier... but i don't see a whole lot.

anyway, i'm just curious

*makes an irrelevant comment about how riding a 20" trials bike is gay as hell*

Trials bikes have different geometry, I'm not sure how the angles differ but I do know they aren't the same.

Also trials riders will almost always run either discs, or hydraulic v-brakes with tar on their rims. And the gearing is a whole lot lower, since instead of getting up to speed they need to do pedal kicks and stuff.
Plus a lot of trials bikes don't have a seat, and if they do it's just a plastic one-piece thing to save weight. And they usually run pretty wide tires with not much pressue in them to absorb the force of drops.

This site will explain better for you, if you haven't checked it out yet:

trail bikes are a little lighter the frame is somewhat stronger and geared for more excell for easy ride

the frame is somewhat stronger

Uh... no.

Uh... no.

Nor is the stem.

I hope that link took care of all the questions. Rev. Chuck, another mod, knows quite a bit about trials as well. Send him a PM.

I had never heard of trials bikes before this thread...I though everyone was misspelling trails.:eek: :D

You did see the pics of my cave, didn't you?

most tirals stuff is done on one wheel
its kinda like hopping around from ledge to ledge...and i think off some pretty big drops

bmx is more flow and big tricks.

i spelled trials wrong. im not gonna go edit it.
deal with it.

BMX>any other type of bike riding. And if you don't believe that then what the cocking-flaps are you doing here?

Besides what has already been said, 20" trials bikes use a 19" rear rim with a really fat, grippy, bouncy, low pressure tire.
They also usually have a bash guard built into the frame to protect the chainring, and are made to use super small (compared to other kinds of riding) chainrings and big rear cogs, to get the low gearing needed for short bursts of power.
Another big difference is that the rear cog is usually fixed, while the freewheel is in the bottom bracket.
