1997 Specialized started it’s Fatboy BMX Line up with just 4 race models. They were instantly recognizable
by the fat oval tubes & Y shaped frames. This design was something no one had seen before.
1998 They would add a 24” version of the aluminum A1, an Expert version of the 4130 Fatboy & a
Park/Street model with the all chrome Flyboy. This would be the only year for both the 24” A1 & Flyboy.
1999 Specialized would release 4 new frame designs. First a new Monocoque aluminum frame in both 20”
& 24” versions for the Fatboy race line. A new 4130 street frame with the 415 line, & the all new 4130
Vegas line for dirt jumping. This would also bring the Fatgirl with a sloped top tube for female riders. The
Monocoque frame would prove to be stronger & more durable than the previous Y framed race models.
The Vegas & 415 would complete the lineup with 10 complete bikes.
2000 Would make more improvements to the Monocoque frame, redesign the 415 & improve the Vegas
frames. Specialized also added the TRX version for a mid level bike. Little racers would also get smaller
versions of the Monocoque frame in both Mini & Expert sizes. Color Options for some models were added.
2001 The Fatboy name was dropped from all the models. The year would bring more improvements to the
Monocoque frame & would introduce the S-Works Hydro-Form frame for racing. Both the 415 & Vegas
frames would again see improvements along with adding an expert version of both.
2002 Brought the beginning of the Hydro-Form Hemi line. The same technology from the 2001 S-Works
frame was brought to the Hemi Pro, Hemi Comp & a 4130 version for the MX. Improvements were again
made to the 415’s & Vegas frames designs with dual cable routing. The S-Works DIRT & ST (street)
frames were introduced as frame only options made of high end Reynolds 853 butted Steel. The S-Works
Race frame was improved & a 24” model was added. Both came with an optional Disc Brake mount. The
Vegas line saw the introduction of the Dirtboy & TRX 24”.
2003 Brought 15 models plus 3 S-works frames. All the race bikes now came with Euro bottom brackets.
The Vegas frames were redesigned again to look more like the S-Works Dirt frame. The 415 line would also
undergo a transformation to look like the S-works ST frames. The Streetboy would be added to the 415
2004 Would bring big changes to every bike. The 415 & Vegas lines would be replaced by the New Fuse
models. A New S-works Fuse frame & a New S-works Hemi frame were introduced. The Hemi frames
were completely redesigned to be lighter, stronger, & stiffer. And a full line of Kids Hemi’s were added
from mini, junior, & expert.
2005 This would be the last year Specialized offered a full line of BMX bikes. The Hemi’s would only get
new paint jobs & decals. The S-Works Fuse frame would see improvements but the S-Works Hemi would
remain the same with a Brushed Aluminum option.
2006 Specialized would cut the Hemi line right before production started. They would only offer the Fuse
models from now on. The S-Works BMX frames were also cut from the lineup right before production.
2010 This would be the last year of the Fuse BMX line.
2011 Specialized would create the P Series BMX Line. Only 3 bikes would be offered this year. A P20
Amateur would be the lower grade frame & bike. A P20 Pro would be the High end Frame & complete
bike. There was also a P24 added to round out the BMX models.
2012 Specialized would Drop the P24 form the lineup. They would add the P18 Amateur for younger Kids
2014 Specialized would make a all new Reynolds 520 Double Butted Frame for the P20 Pro. The Amateur
would come in Hi-Ten Steel again.
