Interesting frame, not sure what I got I just bought this nifty looking bike, but alas I don't know the manufacturer or model it is. There's a logo with a silver looking &quot;Z&quot; and a made in Taiwan sticker. Any help you can provide would be greatly appreciated.
P.S. There was also a sticker that said the bike was &quot;Manufactured Exclusively for S.B.S. Inc., Seattle&quot;. Seattle Bike Supply closed about 5 years ago.
It looks a lot like this 1998 Zephyr Boardwalk 6

The Boardwalk also came in a single speed. Both bikes came in men's and ladies models.
Sorry about the bad picture, I looked for better ones.
The &quot;Zephyr&quot; brand was also used to on BMX bicycles.
On the linked BMX bike the logo is similar and there is a &quot;MANUFACTURED EXCLUSIVELY FOR S.B.S INC. SEATTLE WA&quot; sticker.
If the BMX Museum is accurate the BMX bikes were made between 1985 and 1999
Interestingly there is also a &quot;Torker Boardwalk 6&quot; cruiser which looks a lot like the Zephyr. It turns out that:

In 1984, the Torker Bicycle Company went bankrupt, and Seattle Bike Supply purchased the name.
