Carbon20 Highlights
14.9kg Ultra-Light Design
Lightweight Comfort for Every Rider
At just 14.9kg including the removable battery, Carbon20 makes mobility effortless. Elderly users can lift it upstairs or push it with ease, enjoying reduced fatigue, safer handling, and greater comfort in every moment of the ride.
2.0kg Lightweight Rear Motor
Powerful Assistance, Whisper-Quiet Ride
The 2.0kg rear hub motor delivers 250W of power and 42Nm torque, ensuring steady and silent acceleration. Its balanced placement enhances control and smoothness, giving you power without compromise.
Global Supply Efficiency
From Purchase Order to European Retailers in Just 2 Months
Our mature global supply chain and optimized logistics system enable fast-track delivery. From factory production to European retail partners in only eight weeks—ensuring faster availability and smoother market launch for Carbon20.
Aerospace Technology Empowerment
Flecca CFRP — From the Sky to the Street
Powered by Go Macvol’s exclusive Flecca (Flexible Compound Carbon Architecture) composite technology, Flecca integrates aerospace-grade CFRP (Carbon Fiber Reinforced Polymer) — a cutting-edge composite material — and innovative Mg-Al alloy processing techniques . This Flecca-driven synergy delivers ultra-high tensile strength and extreme lightness; since the Carbon20’s frame is made of this Flecca material, it is over 40% lighter than aluminum while withstanding greater impacts, ensuring every ride is built on aerospace-level foundations.
Aerospace-Level Testing Certification
Proven by Aviation Standards
Carbon20 has undergone rigorous testing by one of the leading aerospace testing institutions in the Asia-Pacific region, the same experts who certify aircraft components such as Rolls-Royce engine blades. This aerospace-level validation ensures uncompromising performance, durability, and safety in every ride.
Aerospace Simulation + Modular Architecture
Stability Meets Flexibility
Engineered with the Abacus aerospace simulation platform, Carbon20 optimizes stress distribution across the frame for enhanced stability. Its modular architecture enables customized structural optimization, ensuring seamless adaptation to diverse urban and leisure riding scenarios.
Color Your Ride
Personal Expression Through Design
Choose from Matte Black, Sky Blue, Energy Orange, and Lavender Purple. Whether you prefer minimalist elegance or bold individuality, Carbon20 brings your personality to life with a color that matches your mood.
Patented Battery Dock Design
Smart Integration, Effortless Energy Access
The patented battery compartment merges flawlessly with the carbon frame. With a simple motion, the rider can remove or insert the battery within seconds—resolving the long-standing inconvenience of battery replacement in traditional carbon eBikes.
Samsung Battery System
90km Range. Reliable Power. Peace of Mind.
Equipped with Samsung 18650 high-performance cells (336Wh), Carbon20 delivers up to 90km range on flat roads. Its stable discharge curve and long lifespan ensure consistent power—ideal for daily commuting and weekend exploration alike.
Leading the Way, Verified by Authority

Aerospace - Grade CFRP Material: The Core Support for Lightweight and High - Strength

The frame of Carbon20 adopts the aerospace - grade Flecca® patented technology, innovatively combining aerospace - grade CFRP (carbon fiber reinforced polymer) with magnesium - aluminum alloy. As a high - performance material commonly used in the aerospace field, CFRP has the dual characteristics of "ultra - lightweight" and "high - strength". Compared with traditional aluminum alloy frames, the frame of Carbon20 is reduced in weight by over 40%. Meanwhile, its tensile strength and impact resistance are significantly enhanced. It not only enables the entire vehicle (including the battery) to achieve an ultra - light weight of 14.9 kg, but also can handle the bumps and stresses during urban cycling, laying a foundation for safety and portability.

Abacus Aerospace Simulation: Precise Optimization of Frame Performance

To maximize the structural advantages of the Flecca® composite new carbon fiber frame, Carbon20 introduces the Abacus aerospace - grade simulation platform for frame design optimization. Derived from aerospace structural simulation technology, this platform can accurately simulate the stress distribution of the frame under different cycling scenarios (such as climbing, sudden braking, and bumpy roads). Through multiple rounds of simulation iterations, the frame's curvature and the thickness of stress - bearing nodes are adjusted to ensure lightweight while improving structural stability and durability. Ultimately, it achieves the goal of "suitability for all cycling scenarios", allowing the frame to maintain a stable stress state during daily commuting or short - distance leisure rides and avoiding damage caused by local overload.

Low Carbon Emissions throughout the Life Cycle: The Balance between Environmental Protection and Performance

Relying on the material properties of CFRP and modular production processes, Carbon20 achieves a significant reduction in carbon emissions throughout its life cycle. Compared with traditional aluminum alloy ebikes and traditional all - carbon - fiber ebikes, Carbon20 has significantly lower carbon emissions in all aspects, from frame raw material production and frame manufacturing to the production cycle and transportation. It not only optimizes the choice of frame materials and production processes to effectively reduce carbon emissions, but also further reduces energy consumption with its shorter production cycle. Through comparative analysis, Carbon20 has a substantial reduction in overall carbon emissions compared to traditional models.
