Eastern is a company that has its roots in BMX. Eastern has done very well at bringing high quality bikes and bike parts at affordable prices. Eastern, in recent years, has branched off into making 26” Dirt Jump bikes and these bikes are stacked with great parts and frames!

The Thunderbird Bike is Eastern’s mid level Dirt Jumper Mountain Bike. The frame is made from durable Chromoly. The frame also has an integrated headtube and Spanish bottom bracket. The SR Duro DJ-D 100mm travel fork has a 20mm Thru-axle. This fork is tough enough to tackle the trails and keep on going. This Thunderbird has a 12T steel cassette driver paired with a 25T Eastern Phorcys alloy Chainwheel. This provides a comfortable all around gear ratio of around 3.9, or 4.3 meters development. To help move this bike along, it’s fashioned with a durable half-link chain. Half link chains add a degree of control over your wheel base with horizontal drop outs.

The Thunderbird is a fantastic Dirt Jumper with a strong component build. This bike is strong where it needs to be while remaining comfortable where it matters. If you’re looking for a bike with great components that won’t break the bank, then the thunderbird is for you.
