I keep looking for info about the bike and where it came from, Bike Beat.
The shop is mentioned in this MBA article from 1991:
"Bike Beat in Orange County was one of the premier bike shops in the country and certainly the Los Angeles. There was a close relationship between MBA and Bike beat and according to Doug many bikes that were sent to MBA for test reviews came back adorned with Bike Beat decals."
"although Doug believes this bike was built only for the test and specifically made to fit Zap from MBA it may have been sent to Bike Beat for assembly and thus recorded that way in the ledger, but there is no way to confirm that. Bike #175 was also annotated with an (EASTON) comment and was logged under Cambria bike (another major bike shop in California."
Bike Beat is mentioned a few times in this thread, Defunct bike shops.
