About Us

BTLOS is the first letter of each word that "Beyond the Limits of Self". It was created from our pursuit of yearning for life. Cycling is an extreme sport. We hope that every rider can go beyond the limits of self, create infinite possibilities, enjoy life, and enjoy riding.

Xiamen Btlos Bicycle Co., Ltd. is a professional manufacturer focused on the design, development, and production of carbon fiber bicycle road rims, carbon mountain bike rims, carbon fat bike rims and carbon wheelsets.
After many years as an OEM manufacturer/supplier, in 2017, BTLOS launched our consumer website making our years of quality and manufacturing expertise available direct to the consumer at the retail level for the very first time.
