Urban mobility is changing rapidly. As traffic congestion peaks and environmental concerns become more urgent, city dwellers and commuters are seeking alternative modes of transportation. While traditional bicycles and two-wheeled electric bikes have long been the default choice, a new contender is redefining stability, utility, and comfort on city streets: the folding electric tricycle.

Addmotor, a pioneering brand in the e-mobility industry, has consistently pushed the boundaries of micro-mobility engineering. Among their folding electric trike lineup, the Addmotor Citytan M-315 (750W) and the Addmotor Citytri E-310 (750W) stand out as exceptional solutions tailored for modern urban living. Combining robust power, advanced battery technology, and smart space-saving designs, these two trikes cater to distinct rider preferences while maintaining uncompromised safety and versatility.

This comprehensive guide explores the specific technical features, performance capability, and functional advantages of each model—individually and thoroughly—to help you discover which 750W electric tricycle fits your lifestyle.

Engineering Foundation: 750W Motor & Safety Systems

Before examining what makes each model unique, it is vital to understand the high-performance core technology that Addmotor integrates across both platforms. Trikes carry more inherent structural weight and cargo volume than standard e-bikes, requiring robust powertrains and safety systems.

Both models feature upgraded 750W nominal rear-drive motors capable of delivering up to an impressive 1400W of peak power and 90 Nm of torque. This heavy-duty configuration ensures that accelerating from a complete stop feels seamless, even on a 15% incline with a fully loaded rear basket. Both models reach a top design speed of 20 MPH, perfectly aligned with Class 2 e-bike regulations.

Crucially, Addmotor integrates a mechanical speed differential into the rear axle of both trikes. When turning a three-wheeled vehicle, the outer wheel must travel further and faster than the inner wheel. The differential ensures smooth, balanced cornering, enhancing rider stability and control during sudden turns.

Furthermore, both tricycles utilize an identical premium safety framework:

• Triple Disc Brakes: Dedicated mechanical disc brakes on all three wheels ensure balanced braking force, preventing pulling or skidding.
• Parking Brake System: Integrated parking brake levers lock the wheels completely when stationary to prevent rolling on inclines.
• EB 2.0 Lighting Ecosystem: A high-lumen front headlight pairs with an advanced 5-in-1 taillight cluster that features integrated brake lights, hazard lights, flashers, and fully functional left/right turn signals operated directly from the handlebars.

The Addmotor Citytan M-315 Folding Electric Trike 3-inch Tire Cruiser

The Addmotor Citytan M-315 is engineered specifically for riders who value ultimate comfort, rugged stability, and all-terrain adaptability. It redefines the traditional cruiser experience by combining heavy-duty components with an incredibly accessible frame design.

Frame Architecture and Ride Ergonomics

The structural backbone of the Citytan M-315 is crafted from heavy-duty alloy and features an ultra-low 14.1-inch step-through frame. This intentional design allows riders with limited mobility, balance concerns, or stiff clothing to mount and dismount the vehicle effortlessly without having to swing a leg over a high top-tube.

With a generous 47.2-inch wheelbase and a premium front suspension fork offering 80mm of travel, the Citytan M-315 delivers a smooth, highly stable ride. The geometry encourages a relaxed, upright riding posture that reduces strain on the rider’s back, neck, and shoulders during long journeys.

All-Terrain Tire Specification

What truly sets the Citytan M-315 apart is its rugged tire configuration. It comes equipped with 20″ x 3.0″ fat tires on all three wheels. The extra width provides a massive contact patch with the ground, lowering overall tire pressure. This enables the Citytan M-315 to glide effortlessly over potholes, light gravel, sand, and uneven city asphalt, acting as a natural shock absorber that handles rough road surfaces better than standard narrow tires.

Xuanwu Battery Performance & Range

Powering the Citytan M-315 is a high-capacity 48V×13.5Ah (648Wh) battery pack incorporating Addmotor’s proprietary Xuanwu battery technology. Rather than using vulnerable, standard plastic-wrapped battery packs, the Xuanwu system sets a new benchmark for safety.

The internal cell structure is completely embedded in a specialized, thermally conductive silicone potting material, providing superior IPX5-rated waterproofing and absorbing heavy road shocks. Encasing the core is a heavy-duty aluminum-alloy structural case that acts as an efficient heat-dissipation surface area. This ensures stable power delivery, protects cell longevity, and provides critical physical armor. Positioned cleanly behind the seat tube to maintain an optimal center of mass, this battery delivers up to 50–65 miles of range per charge using its multi-level Pedal Assist System (PAS) or convenient half-twist throttle.

Portability and Cargo Capacity

Despite its rugged fat-tire profile, the Citytan M-315 features a heavy-duty folding frame with quick-release hinge clamps. It folds down into a compact footprint (41.3″ L x 43.3″ W x 45.3″ H), resolving the storage limitations typically associated with utility-focused fat-tire vehicles. For utility, the reinforced rear frame sections comfortably support substantial payloads, making it an ideal alternative for heavy grocery shopping or weekend hauling.

UL 2849 Certified Addmotor Citytri E-310 Folding Electric Trike Nimble Urban Commuter

Mixed Wheel Size & Agile Proportions

The standout structural innovation of the Citytri E-310 is its unique mixed wheel size format: a 20″ x 2.4″ tire in the front combined with dual 18″ x 2.4″ tires in the rear. By utilizing smaller wheels in the rear, Addmotor successfully lowers the trike’s overall center of gravity. This design modification significantly improves lateral stability, dramatically reducing body roll and increasing driver confidence during high-speed urban maneuvers.

Additionally, the Citytri E-310 features a streamlined width profile of just 28.3 inches. This narrow footprint allows the vehicle to slip easily through standard doorways, narrow city bike lanes, and crowded elevators where traditional adult tricycles cannot fit.
