    Can you include images of the frame and anything that may stand out such as logos, decals, interesting lugs etc it will help greatly in identifying it if possible. Welcome to SE Bicycles!

Google is your friend. Based on a report from the South Yorkshire Police , they received a report of a stolen BMX with "mbi-2325" as the "serial number" in 2010. Seems to be a mistake in that was a frame model and the serial number is one of the other values.

However this same police report lists it as


which means little to me. More Google returns http://www.vitalbmx.com/product/feature/Mirraco-Blend-Two-Complete-Bike,2275
