Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

Merida - Big Nine 20 Black/Silver



  • 16 Speed
  • Hydraulic Brakes
  • Lightweight Alumnium Frame
  • X-taper Headtube
  • Internal Cable routing
  • 29 inch Wheels


29er hardtail with sophisticated TFS aluminium frame, 2 x 8 transmission, lockout fork and Shimano hubs and chainset Merida's heartland has always been bombproof aluminium hardtails. Half a century of frame building experience counts for a lot.

Merida UK chose to upgrade all the Big Nine and Big Seven bikes destined for the UK to use a sophisticated TFS frame featuring the latest technology:

full internal cable routing, for a neat and clean set up,
tapered headtube for future upgrade potential
inboard disc brake mounts to protect the brake and maximise stopping power

Perfectly matching the modern frame Merida have used as much Shimano componentry as possible for reliability.

Merida offer a wide range of sizes, Big Nine for taller riders, Big Seven for shorter riders with a healthy overlap of sizes in between.

For riders in the middle, riding style can be taken into account. If you are looking for speed and efficiency choose a Big Nine, if you are looking for agility chose a Big Seven.
