Addmotor Launches Freetri E‑361 Semi‑Recumbent Folding Electric Trike Built on Freetan Platform

EL MONTE, CA, September 2nd, 2026, FinanceWire

Addmotor, a U.S. manufacturer of electric bikes and electric tricycles, launched the Freetan platform earlier this year, generating strong market response and positive operational feedback. The company today introduced the Freetri E‑361, a folding semi‑recumbent electric trike developed on the Freetan platform architecture and its comfort‑geometry foundation. The specification centers on a 750W rear‑drive motor system and the Xuanwu 48V 20Ah full‑potting battery pack built with Samsung 21700 cells. Additional structural elements include a folding frame, a semi‑recumbent layout, and an adjustable handlebar‑and‑backrest assembly.

Freetri Built on the Freetan Platform

The Freetan platform is Addmotor’s semi-recumbent trike architecture designed for reduced spinal load, stable three-wheel support, and extended operating range. Developed on this standardized foundation, the Freetri E-361 directly carries forward the core electrical and mechanical systems of the Freetan M-368X, including:

• Power & Control Systems: A 750W rear-drive motor, the EB 2.0 intelligent control platform, and the EC 3.0 electronic control system.
• Battery System: The Xuanwu 48V 20Ah full-potting battery structure built with Samsung 21700 cells.
• Platform Extensions: A newly integrated foldable frame, a tapered triangular saddle to eliminate thigh-root interference, urban-calibrated suspension, and optimized 18" × 3.0" front / 20" × 3.0" rear tires for enhanced paved-surface grip.

Folding Frame for Storage‑Constrained Environments

The trike measures 72 in × 29 in in riding configuration and clears standard 30‑inch interior doorways. When folded, the chassis compresses to 51.9 in × 29.9 in × 41.7 in, enabling storage in SUV cargo areas, apartment closets, and RV touring bays. Reinforced joints maintain load stability during transport.

Semi‑Recumbent Geometry

The Freetri incorporates a 90°–170° adjustable backrest and an adjustable handlebar assembly. The backrest supports upper‑body load and reduces axial compression on the lumbar region by transferring part of the rider’s weight into the seat‑back structure. The triangular saddle uses a forward‑tapered profile to eliminate thigh‑root interference and maintain full leg‑extension clearance. The handlebar assembly provides height and reach adjustment from 42.1 to 51.1 inches, accommodating riders from 5'1" to 6'7" without altering the semi‑recumbent geometry.

750W Rear‑Drive Motor with Digital Torque Sensor

Equipped with a 750W rear‑drive brushless motor delivering 1400W peak output and 90Nm of torque. The motor uses an upgraded stator layout and high‑density copper windings to improve thermal stability under sustained load, supporting consistent output during climbing, acceleration, and long‑duration operation.

The model incorporates Addmotor’s dual‑signal digital torque sensor using a spline‑tooth axle and a mechanically‑locked interface to maintain rigidity under high‑frequency torque input. The sensor provides fully digital left‑ and right‑side torque data, with both channels encoded and transmitted directly to the controller to support linear pedal‑assist response and produce consistent left‑right input symmetry compared with systems that rely on algorithm‑generated right‑side signals.

The EB 2.0 platform manages PAS logic and lighting, while the EC 3.0 controller processes torque‑sensor data at micro‑second intervals. EC 3.0 applies low‑speed modulation to suppress initial torque spikes and maintain proportional assistance based on real‑time pedal input. Together, the rear‑drive motor, dual‑signal torque sensing, and EC 3.0 modulation form the complete electrical drive chain of the Freetri

48V 20Ah Full Potting Aluminum Housing Battery Using Samsung 21700 Cells

The 48V 20Ah (960Wh) Xuanwu battery uses Samsung 21700 cells embedded in thermally conductive silicone and enclosed in an aluminum shell. The full‑potting structure forms a solid block that absorbs vibration, prevents micro‑fractures, isolates the cells from moisture, and conducts heat during discharge.

Samsung’s 21700 cells provide higher thermal tolerance and stable cycling performance compared with 18650 formats, supporting 3C‑class discharge behavior and maintaining capacity retention under standard cycling conditions. The company integrates BMS charge‑ and discharge‑protection functions, temperature sensing, and UL‑2271 certified safety control into the pack design. The battery supports up to 85 miles per charge on PAS Level 1 and retains 70%–80% of its capacity over 1,000 cycles.

Mechanical Stability Systems

• Rear Differential System — A mechanical rear differential allows independent wheel rotation and reduces tire scrubbing during cornering.
• Step‑Through Geometry — A 14.1‑inch step‑through height supports stable mounting and dismounting.
• Rear Anti‑Tip Stabilizers — Rear stabilizer structures increase lateral stability and reduce roll tendency during low‑speed turns or uneven‑surface operation.
• Front Suspension — A front oil‑spring suspension fork absorbs road irregularities and reduces forward‑impact transfer to the frame.
• Tire Grip & Compliance — High‑grip tires increase traction and contribute to vibration absorption on mixed surfaces.
• Braking System — Mechanical disc brakes on all three wheels provide stopping power, and a parking lock supports incline stability during loading or stationary positioning.
• Visibility Systems — Reflective tire sidewalls and EB 2.0 integrated rear lighting with turn signals support visibility in low‑light conditions.

Pricing and Availability

The Addmotor Freetri E‑361 is available with a suggested retail price of $2,699.

Available color options include:

• Neptune Blue
• Bay Blue
• Avocado Green
• Cream Yellow

All configurations include double‑walled aluminum rims.
