Merida Big Nine 80 MTB 2025

The perfect partner for mountain bike adventures as well as a rugged day-to-day companion, the BIG.NINE 80 features a quality double-butted aluminium frame with comfortable geometry and smooth rolling 29er wheels to tame the bumps. With the control of a 100 mm RockShox suspension fork, the dependable performance of a Shimano 9-speed drivetrain, and powerful hydraulic disc brakes, it's ready for weekend adventures or to be a reliable partner during the week.

Our bikes come fully assembled and ready to ride, and we offer the first service for free.

Mountain biking is one of the most varied cycling disciplines and probably the most demanding when it comes to equipment. While full suspension bikes offer amazing riding characteristics, the classic hardtail remains one of the purest tools for the job. Our 29er wheel-equipped BIG.NINE range comes in carbon and aluminium and features multiple geometry options. 

Our classic hardtails are the backbone of our range and showcase the enormous wealth of experience and knowledge we have gained in over half a century of bike production and manufacturing. The BIG.NINE range represents the symbiosis between modern frame technology, attention to detail, and craftsmanship 'Made in Taiwan.'
