Two Years Toward the Absolute: Addmotor Freetan M‑368X Full‑Suspension Recumbent E‑Trike Story
Addmotor Freetan M‑368X
The Story Behind the Addmotor Freetan M‑368X Full‑Suspension Recumbent E‑Trike
From the beginning, Addmotor has been driven by a simple but powerful mission: to make the joy of riding accessible to everyone—regardless of age, physical ability, or riding experience. For more than a decade, we have dedicated ourselves to building electric tricycles that restore freedom, expand mobility, and redefine what comfort can mean on three wheels. The Freetan M‑368X represents the purest expression of that mission.
The Freetan M‑368X is more than a new model—it is the culmination of a two‑year pursuit of absolute comfort, engineering purity, and uncompromising ride quality. Every curve, every joint, every millimeter of adjustability reflects a development journey defined by persistence, failure, reinvention, and breakthrough.
1. Two Years of Research and Development
The Two-Year Journey: From Failure to Breakthrough
The Freetan M‑368X began as an ambitious idea that took two full years to mature. Early in development, the team explored a left‑right swing mechanism, investing six months, eight design iterations, and three prototypes—yet none met Addmotor’s stability and safety standards.
A turning point came from market feedback. Inspired by simplicity and reliability, the team made a decisive shift: abandon unnecessary complexity and focus on full‑suspension comfort and a low‑step, universally accessible frame.
The most challenging design of the lead engineer's career
The Freetan M‑368X is the result of 12 months of dedicated work from Addmotor's lead designer. Among all models he has created, this trike stands as the most technically demanding—engineered to deliver the most comfortable riding experience ever offered by Addmotor, while balancing aesthetics, practicality, and universal usability.
2. Core Design Innovations & Engineering
Structural Structural Design for Comfort
Full-suspension system: Equipped with front and rear absorber forks. And Rear suspension was tested across 300–1000 lb spring rates and tuned for 200–250 lb riders. It offers about 4–5 cm of compression, starts firm, softens after break‑in, and delivers best comfort around 200 lb.
Low‑step through frame: Ultra–low step–through frame for easy on/off access, ideal for mobility–limited riders and stop–and–go riding.
Maneuverability & Rider Adaptability
Minimum turning radius: ≈2 m; completes a 180° turn in one car lane with the left wheel nearly stationary for precise low‑speed control.
Handlebar adjustability: Height‑ and angle‑adjustable with multiple positions, including an “ape‑hanger” riding posture.
Sliding footrest module: Automotive‑inspired mechanism with a wide adjustment range to fit different leg lengths.
Seat and backrest: Adjustable from 90° to 170° with a wide, supportive design, offering enhanced comfort for riders with lumbar or hip issues and for those with rehabilitation needs.
Fits riders from 5'1'' to 6'7''.
Advanced Engineering & Elite Workmanship
Fully Internal Cable Routing
Brake, shift, and electrical lines are completely hidden inside the frame. This requires complex internal grooves and precision threading procedures, delivering a clean, premium appearance with zero exposed cables while protecting the wiring system.
Self-developed Universal-joint Steering
Moving beyond off-the-shelf U-joints with large play, Addmotor engineered a steel gear-mesh universal joint. Using custom-molded components, this innovation eliminates steering looseness and delivers unmatched precision and feedback.
Three-wheel-specific Torque Structure
Adapted from motorcycle engineering, this reinforced, oversized tubing system was redesigned for trike-level torque loads. Key areas use custom-molded parts and have passed rigorous heavy-load and stress testing.
High-difficulty Assembly & Support
Due to the sophisticated internal routing and limited space, internal cable replacement requires a dedicated pull-string tool. To ensure a seamless experience, early production units will include custom installation accessories provided by Addmotor to assist customers with maintenance.
Upgraded Performance & Safety
Electronic Control System
The electronic control system uses a proven 2.0 architecture paired with the 750W EC 3.0 controller and a 48V 20Ah battery with integrated lighting. To accommodate the low‑step frame design, it adopts a small chainring and a two‑stage reduction system, keeping the chain line low and the drivetrain structurally optimized.
Self-developed Steering
Instead of using off‑the‑shelf U‑joints with excessive play, Addmotor developed a steel gear‑mesh universal joint paired with custom‑molded components. This proprietary design eliminates steering looseness and delivers significantly improved precision.
Battery Technology
Use a full potting process (applicable to both Kirin and Xuanwu models), the pack is filled with thermally conductive silicone to deliver enhanced heat dissipation, safety, and waterproofing. The Xuanwu model features a mid‑section aluminum alloy housing that increases the heat‑dissipation surface area and helps prevent battery thermal runaway.
Reinforced Chain System
The secondary chain between the motor and the differential has been upgraded to a motorcycle grade, thicker and reinforced design. It uses a different specification from the primary chain and resolves previous issues of twisting or breakage under high torque. All trikes have adopted this upgrade since October–November of last year.
Additional components: We've introduced a chain guide wheel to avoid foot interference and a side-mounted front basket with a custom-molded M-head integrated into the injection mold.
3. New Color & Aesthetic Direction
Avocado Green
Inspired by Addmotor’s helmet design, custom‑mixed for a soft yet modern tone. It reflects a new visual identity that is vibrant yet sophisticated.
Bay Blue
A lighter, more refreshing shade that visually reduces the mass of the large frame. Both colors pair with our signature orange wheel rims, creating a recognizable identity.
A New Benchmark for Comfort
The Addmotor Freetan M‑368X is not simply a recumbent e‑trike—it is the most ambitious comfort‑focused platform Addmotor has ever built. Born from two years of iteration, failure, and breakthrough, it represents a new standard for full‑suspension recumbent riding, universal adjustability, and precision engineering.
Ride in Comfort. Move in Freedom. Freetan M‑368X.
In the next chapter, we will take a closer look at how the Freetan M‑368X transforms these engineering breakthroughs into real‑world riding advantages—its performance on varied terrain, its ergonomic philosophy, and the unique rider scenarios it was built to empower.
