This all-new Wiki Peak is the best we have ever built!  Better pedaling saves rider energy, better descending to instill confidence, and a more active, lively suspension design makes sure you return to the trail head with a smile on your face.

The heart and soul of the Wiki Peak is the new Tetra-Link suspension design combined with our GA-Link Geometry.

  • Climb-conquering pedaling efficiency – the suspension kinematics have been refined to increase pedaling efficiency and get you to the top of the climb faster and with more energy in your legs.
  • A plush/bottomless feel – Fezzari designed a very progressive suspension to give an incredibly plush ride. This leads to great small bump sensitivity while preserving mid-stroke support.
  • Active braking – the design ensures the suspension stays active under braking, even through technical sections.

Fezzari’s GA-Link Geometry allows you to adjust the geometry for both 27.5 plus and 29er wheels while maintaining a consistent bottom bracket height between the two platforms.

The Wiki Peak may be our entry level full suspension bike, but it can hold its own against the more expensive rides. On the 27.5+ platform, the Wiki Peak's AT529 frame has all of the key features of its more expensive counterparts, like 12mm rear axle and tapered headtube for stiffness, boost spacing, sealed bearings on the pivots, and smooth welding. With 5.1" (130mm) of rock-chewing suspension travel, 27.5+ wheels, and an efficient pedaling platform, you'll climb parts of trails and descend through sections you didn't think were possible. Shimano hydraulic disc brakes will keep your speed in check.

Combine these features with our 23-point custom setup and you have a quality bike that is specifically built with your riding style in mind. If you are looking for your first full suspension mountain bike or want to upgrade your current ride and price is important, you can't beat the value and ride quality the Wiki Peak offers.

Industry Reviews

Fezzari is a company that has customer service on the brain.

Our look at the details suggest that the company has done their homework.

Initially [the factory direct] process may sound a bit cold and corporate, but in reality, it's quite the opposite.

Customer Reviews

ONE of the BEST CUSTOMER service companies, bar none!!

by Jay Mentz (Walden, NY)

I don't know where to write a review of ONE of the BEST CUSTOMER service companies, bar none!! From Dan who built my bike to Maddie , Melisa (Sorry if I got her name wrong), and Ian!! This WIKI PEAK is above all my expectations. Buy any of these FEZZARI bikes and go ride. I own two. Just upgraded to the WIKI PEAK and the friends I ride with are all huffin and puffin as I glide past and remind them that they should buy a Fezzari. Then I laugh all the way up the hill and wait for them to walk their Specialized bikes up. Thank you all again for such an awesome buying experience and for the quality you have achieved in your products. Jay P. Mentz

I just upgraded to the WIKI PEAK and I am blown away! I have the Lone Peak. I want to thank the AWESOME customer service people at Fezzari. I spoke with Maddie, Melisa, and Ian. I can't say enough positive things about these dedicated people. I was telling them how I have been telling my friends to buy a Fezzari. I love to pass them on hills and say,"You should buy a Fezzari." I then laugh as I wait for them to walk their Specialized bikes up. You can not match the value and the service Fezzari ofers. By far the best bikes on the market.

Blown Away!

by Kerry McGinnis (Opelika, Al)

I have been shopping and test riding bikes for about four months, and this Wiki Peak is the best bike I have ever ridden. It takes other brands two to four times the cost to compare with this bike. The fit is perfect, it digs into the turns, it is soft on landing drops and jumps, and sometimes I do not even notice when I have started going up hill. My friend who had his eye on a EX 8, is now looking at your Hidden and Cascade peak after riding my Wiki.
