INTRODUCING THE 801

June 10, 2025

Ari Bikes is excited to introduce the all new 801, the revival of its dirt jump and pump track bike. The 801 is built to enhance your skills—or just have fun on two wheels. Choose the 26” for flickable control on dirt jumps and tricks, or the 27.5” for a more trail-ready feel that builds skills on pump tracks and carries over to mountain bike rides.

Who’s it for:

When fun and progression are the highest priority. The 801 is a bike built for dirt jumping, slalom racing, and pump tracks. What about skills training? The 801 is the perfect bike to improve riding technique on whether an XC enthusiast or enduro racer.

Key Features of 801:

1. 26in or 27.5in Frames

Pick your wheel size. With two frames for either 26 inch or 27.5 inch wheel sizes, riders can optimize their ride for what they find most fun. Choose the 801 26’’ for nimbleness on dirt jumps or the 801 27.5’’ for extra stability and versatility on pump tracks and dual slalom courses. (It’s still no slouch while jumping!) The 801 27.5’’ frame also features Boost 148 thru-axle spacing for compatibility with modern hubs and wheelsets.

In Ari’s testing, they found that 27.5’’ wheels better mirror the handling of mountain bikes and translate skills from pump tracks and jump parks more directly to trail riding. This helps riders experience varied terrain and improve their skills as they become a better all-around rider on the 801.

2. Evolved Geometry

Dialed handling for confidence and control. The 801 26’’ has an agile 69° headtube angle, short 385mm chainstays, and 22mm of bottom bracket drop hitting a sweet spot for tackling dirt jump lines. The 801 27.5’’ features a 1° slacker headtube angle, 10mm longer chainstays, and 20mm of additional bottom bracket drop so riders feel locked in on pump tracks and dual slalom courses.

3. 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. Ari tested the frame to the same impact standards as their Superior Peak DH bike ridden in RedBull Rampage. Ride confidently knowing the 801 is designed to take a beating as riders push personal limits and try new tricks.

4. 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 dropping in. The 801 Pro 27.5’’ includes a SRAM GX DH 7-Speed drivetrain for riders looking for expanded versatility. All 801 27.5’’ bikes and framesets include the derailleur hanger as part of the dropout assembly providing a seamless upgrade path if riders want to add gears down the road.

5. Gyro Mount

Tailwhip and barspin all day. Threaded gyro mounts located on each side of the head tube allow for the installation of a rear brake gyro. With this option, riders can tailwhip and barspin over and over without having to remember if they have enough cable wrap for their next trick.

6. Build Your Dream Bike

Framesets available for custom builds. Choose either the 26’’ or 27.5’’ frame and build a dream bike from the frame up. Nuff’ said. Framesets include headset, seat clamp, and rear axle (axle only included on 801 27.5’’ since the 801 26 uses a bolt on rear wheel). Frames starting at $549 (26″) and $579 (27.5).

7. Meticulous Detail

Down to the final bolt. The 801 is equal parts passion and performance. Every feature, angle, material, and spec choice was meticulously defined to provide a refined riding experience.

8. The Complete Experience

The whole is greater than the parts. The 801 blends cutting edge manufacturing, purposeful design, and leading components. Each build level delivers exceptional ride characteristics and immense value. Plus, every Ari bike is backed by a Lifetime Warranty and 30 day Love It or Return It guarantee. With Ari, riders get more.
