Can anyone help me out with this please?

Serial no. HQHA04399L

The frame appears to be a 1999 Expert Pro but stampings state 1998?

Thanks

Yep 1999.

What stampings state 1998?

Im only new to this mate, so bare with me......

But from what I can find it states its a 1998 but from what lim iced info I do know its a 1999.

below is the website I got my info from.

https://shop.re-rides.com/blogs/news/mo … new-school


Mid-school Mongoose BMX bikes built through most of the 90’s have a serial number that begins with 4 letters. The 3rd letter corresponds to the year of manufacture.

A      B     C      D     E      F      G      H      I
91   92    93    94    95    96    97    98    99

The 4th letter indicates the Month

A      B       C      D       E        F       G       H       I          J       K        L
Jan  Feb  Mar   Apr   May   Jun   Jul    Aug    Sept   Oct   Nov   Dec



Is this incorrect or am I reading it wrong?

Are you able to point me in the right direction for this model? For I can't find any catalogs or info on this frame, everywhere I look people have different looking frames and parts on a 1999 expert pro.

Thanks in advance.

You’re reading the SN right using that decoder...

Thanks for the info mate,

So with all that info and the above reference the frame was a 1998 build but was constructed as a Expert pro in 1999?

Being built at the beginning of the year like that, for sure makes it a 1998 Frame, then in 1999 they came out as a complete or ??? (not sure on a Model for it one way or another)

hmmm ok, being this my first build Im not really wanting to step off on the wrong foot and build it to the specs of something its not.

My next question is why do some 1999 25th Anniversary Mongoose Expert Pros have different Seatstays (hopefully I have the right name for it).
Some appear to be stamped and others are not.
Am I looking to far into this??

Pics below are of example of what  going on about.

Could it mean a difference between a Walgoose & a bike shop Mongoose(probably a long reach)

Again mate that's what my thoughts are.

But I didn't think they started doing them until after 1999 and this frame is 1998

Feel free to pm me with info.

Hi Guys any help with this serial number I have HQGI006171 or it may be HOGI006171
