Evolved Geometry
Quickly learn new skills and develop a deeper sense of bike control with geometry that supports your progression. The 801 26" hits a sweet spot for tackling dirt jump lines. The 801 27.5" helps riders feel locked in on pump tracks or dual slalom courses.
Strength and Durability
Robust aluminum frame built to take a beating. The 801 is constructed of 6061-T6 aluminum alloy for high strength in a lightweight, robust package. We tested the frame to the same impact standards as our Superior Peak DH bike that has survived Red Bull Rampage. Ride confidently.
Derailleur Compatible
801 27.5" comes with a derailleur hanger and cable routing for a drivetrain. Drivetrain capability provides gear optimization and the ability to shift to an easier gear for climbing back to the start of a dirt jump line or to a harder gear before you drop in.
2 Frames, 3 Disciplines
Dirt Jumps
801 26 delivers a smooth, responsive ride with precise control, making every jump feel effortless and dialed.
Pump Tracks
801 27.5 glides effortlessly through pump tracks with incredible flow, speed, and precision in every berm and roller.
Dual Slalom
801 27.5 rips through dual slalom courses with explosive acceleration, razor-sharp handling, and confident stability in every turn.
Chassis
Built tough. Finished thoughtfully.
Custom-molded protection quiets chain slap and shields high-impact areas. UDH compatibility simplifies service, while the epoxy-infused finish is made to resist chips and scratches.
Watch
Your cheat code for fun.
If you're the type of rider who loves jumps, tricks, or improving your skillset on the bike, the 801 is for you.

An extensive fit process before sending the bike so that it’s ready to rock.

Common questions
Still deciding? Our team rides these bikes and can help you find the right setup.
Who is this bike for?
The 801 is our dirt jumping, slalom racing, pump track slashing bike built to handle air time and flowy berms. What about skills training? The 801 is the perfect bike to improve your technique on, whether you are an avid XC enthusiast or enduro racer.
Where did the name come from?
801 is a Utah phone number area code we used to name our first dirt jumper that was made of steel. This was in memory of the Geneva Steel Mill that operated from December 1944 to November 2001. It was located just 2 miles from our headquarters and was a local economic driver in the area for years.
Do you offer financing?
Yes, at checkout there are several options available for financing.
How long will it take to arrive?
Estimated lead times are listed under each model's size in the bike builder. Times may vary a little based on current conditions, frame size, color, and availability.
What is the maximum tire clearance?
26in x 2.4in or 27.5in x 2.4in. Front tire: per fork manufacturer.
Can the 801 be set up tubeless? What are the advantages of a tubeless setup?
Yes; however, many dirt jump riders prefer to run tubes to allow for higher psi. Tubeless valves and sealant may be added to your order under Recommended Accessories in the shopping cart. The advantages of a tubeless setup are increased flat protection from punctures and the ability to run a lower tire pressure for increased comfort and traction.
What is the bottom bracket spec used on the 801?
73mm BSA English Thread.
How can I know I am getting the right size?
The 801 is a one-size-fits-most bike.
What about service?
You can work directly with us, one of our recommended shops, or work through your local shop.
What is the warranty?
Each frame comes with a Lifetime Warranty. Ari-branded frames come with a transferable warranty as well.
What is the guarantee?
It comes with a 30-Day Love It or Return It Guarantee.
How does transferable warranty on Ari bikes work?
Ari-branded frames come with a transferable frame warranty available to the second owner. The second owner can receive a one-year frame warranty from the date they purchase the bike from the original owner. Warranty only transfers once. All Ari bikes must have the transfer documented from the original owner to the new owner here in order to qualify for a transferable warranty.
