Lightweight & Powerful
Nebo Peak represents nearly two decades of research and development, coupled with extensive real-world testing.
"The Ari Kings Peak is an impressively well-rounded fat bike with a frame design that makes it a versatile option for both snow and adventure riding alike."
"From the ordering process that utilizes the bike builder on their website to the solid professional pre-build to the in-field testing, the Ari Kings Peak has been totally solid."
"The geometry was developed from the ground up for more stability, maneuverability, and adaptability, plus there are loads of new features that improve on the previous version."
"There are more mounts, and everything is more svelte, from the fork to the rear dropouts. The previous Kings Peak was a good bike, but this one looks massively improved."
"The geometry is ... revolutionary."
"As you go to purchase your next bike, I encourage you to give Ari a look."
"With new buyers, the brand will go through an extensive fit process before sending the bike so that it’s ready to rock."
"I realized how deeply in touch Ari is with what riders want and what the industry needs."
