The MITH Frame Kit from UNNO redefines the standards of full-power E-MTB. With its full carbon chassis, the DJI Avinox M2S motor delivering 1300 W / 130 Nm (150 Nm in Boost mode), and an 800 Wh battery, this frame kit offers one of the lightest and most powerful platforms on the market: only 21.9 kg as a complete bike. Designed and tested in Barcelona, this technical base allows you to build your own machine, without compromise, with your favorite components.

MITH Frame Kit Overview

The MITH Frame Kit includes the T700/T1100 monocoque carbon frame with visible raw twill finish, the complete Avinox M2S drive system (motor, 800 Wh battery, 508 W fast charger, controllers, 2" OLED touchscreen), as well as all integration components: Acros Block-Lock headset, e*thirteen Helix Race 36-tooth chainring, integrated rear triangle and linkage protections. This kit provides the ideal technical foundation to build a custom E-MTB around one of the most advanced suspension kinematics in the industry, the Virtual Pivot system with 160 mm of rear travel.

Next-Generation Avinox M2S Drive System

• Exceptional power: The Avinox M2S motor delivers 1300 W continuous and 130 Nm of torque, with a Boost mode activatable for 60 seconds to reach 1500 W / 150 Nm. This is one of the most powerful systems on the market, with an exceptional power-to-weight ratio (only 2.6 kg for the motor).
• Battery and range: Integrated fixed battery of 800 Wh (3.74 kg), rechargeable from 0 to 75% in 1h30 and from 0 to 100% in 2h25 thanks to the included 508 W fast charger. Ideal for long rides and consecutive bike park descents.
• Technology and connectivity: 2-inch OLED touchscreen integrated into the top tube, handlebar controllers, customizable assistance modes (Eco, Auto, Trail, Turbo, Boost), Avinox mobile app for advanced settings, and GPS tracking via Apple Find My.
• Compactness and discretion: With an ultra-compact format (107 x 172 mm), the M2S motor integrates perfectly into the MITH frame, preserving the sleek aesthetics and handling of a traditional MTB.

Frame Architecture and Virtual Pivot Suspension

• High-performance carbon: T700/T1100 monocoque carbon with visible raw twill finish (without heavy paint layers), for weight savings and a premium finish. Tested beyond ISO standards, the frame comes with a lifetime warranty.
• Optimized Virtual Pivot kinematics: 160 mm of rear travel with optimized anti-squat for efficient pedaling and controlled progression. Compatible with 230 x 65 mm shock, air or coil, without special linkages or compromises.
• Bearings and durability: Oversized EnduroMAX double-row bearings with lifetime warranty. Fully sealed system against spray and moisture, guided internal cabling, integrated rear triangle and shock protections.
• Modern and aggressive geometry: Head angle 63.5°, seat tube angle 77°, chainstays 450 mm. Three sizes (S1 / S2 / S3) with reach of 430, 460, and 490 mm. Mullet configuration (29" front / 27.5" rear), tire compatibility up to 2.6" at the rear.

Standards and Compatibility

The MITH Frame Kit incorporates the latest standards: SRAM UDH (Universal Derailleur Hanger) for compatibility with modern drivetrains, Boost 12x148 mm rear axle, Post Mount disc brake, 170 mm fork compatibility (29") with 44 mm offset. The frame accepts dropper seatposts of 150 mm (S1), 175-180 mm (S2) or 200-210 mm (S3) with an insertion depth of 250 mm. Bottle cage storage possible in the front triangle (650 ml in S1, 750 ml in S2/S3).

Design and Technical Details

The MITH stands out with its avant-garde and sleek design, featuring a strongly sloping top tube and characteristic integrated seat dome. The raw carbon twill finish reflects the actual frame structure, without aesthetic artifice. The seatpost collar is integrated with rubber cover, allowing the use of an exclusive D-shaped seatpost. Recycled molded protections (Oceanworks) on the rear triangle, integrated chain guide, reinforced motor cover with seal. Every detail is designed for performance, reliability and ease of maintenance, even after hundreds of rides.

Available Sizes

• Size S1: Reach 430 mm / Stack 624 mm — for riders 155 to 170 cm
• Size S2: Reach 460 mm / Stack 636 mm — for riders 170 to 180 cm
• Size S3: Reach 490 mm / Stack 658 mm — for riders 180 to 195 cm

Awards and Recognition

The MITH received the Design & Innovation Award 2026 in the E-Mountainbike category. In independent tests, it consistently ranked among the fastest on descents, where only chassis quality matters, independent of motor power. UNNO thus establishes itself as a reference for demanding riders seeking to push the limits without compromise.
