The seat is one of the main contact points you have between you and your bike (along with the pedals and grips) so you want it to be comfortable.
When choosing a seat there is a range of options: pivotal, railed, combo, stealth pivotal, and tripod.
The option available to you may depend on what type of seat post you already own.
We have a large selection of BMX Seats for sale at Backyard BMX including railed BMX seats and comfortable pivotal BMX seats.
