Great site on Sekai

Im still trying to ID my unknown 1977 frame. I found a 1979 ad in “Bicycle Motocross Action in a 1979 issue with a bike just like mine. Leading me to believe if Sekai was in business in 1977 it may be a Sekai. Then I found this great Sekai fan site: http://www.yellowjersey.org/sekai.html

Here is some quick info from it

We proudly sold Sekai bicycles from 1973 until their death around 1986.
Mr Katsu Yamashita worked tirelessly from his family’s firm,
Shinwa Trading Company, to ensure the very best quality and arrange all the myriad details of these wonderful bicycles.
Frames were built by Yamaguchi Frame in Osaka.
Professional Sekai frames, models 4000 and 5000, both road and track, were built by Miki
. Assembly was done at Sakai Export, Osaka.”


1977 Sekai?

Ok hopefully someone who worked at Sekai or owned one back in the day can chime in. I got a unknown BMX bike about a year ago. Never saw another one till recently. The owner of that bike also doesnt know what his is. But both of our bikes are 1977’s. Mine had old old Kuwahara decals pre 1979 font when they introduced them to the USA. So at first I thought maybe a Japaneese 77 Kuwahara. But after making this site I saw the similarities to the 79 Sekai. Hrmm are these two bikes 1977 Sekai’s???

Welcome to Sekai BMX!

Welcome to sekaibmx.WordPress.com. I hope this becomes the site for Sekai fans and those that just love the old small companies. Sekai was a regional company and very popular in its hiome area of the Great Northwest.

This is my fourth fansite. I also created one for Redline, CYC and Powerlite. I plan to do one for Webco, DG and maybe some others.
