UBI Faculty

UBI Faculty

Every UBI faculty member has years of bike industry experience and was chosen for their extensive backgrounds in mechanics, frame building, shop operations, and other industry endeavors. In fact, UBI employees have spent a combined total of more than 200 years in the bicycle industry! Their teaching style creates a fun and creative learning environment which stimulates the mind and allows easy comprehension of each mechanical procedure.

The size of our faculty roster means that UBI has the best student-teacher ratio in the industry. In our mechanics classes, our student-to-teacher ratio is no less than 6 to 1, and in our frame building classes it is a minimum of 4 to 1.
