Addmotor, a manufacturer of electric bike solutions, has announced the commercial availability of the U-Trike U-750. The vehicle implements a central pivot mechanism that allows the chassis to lean during directional changes, a departure from traditional rigid-frame electric tricycles. By utilizing a dual-mode system, the U-750 provides both static stability and dynamic leaning functionality, aimed at addressing common kinematic issues associated with three-wheeled bike platforms.
Mechanical Architecture and Pivot Engineering
The technical core of the U-Trike U-750 is its central pivot joint. In a conventional rigid electric tricycle, the frame remains on a fixed vertical plane, subjecting the rider to outward centrifugal forces during turns. The U-750’s tilting mechanism trike architecture decouples the front steering column and rider frame from the rear drive module.
This configuration allows the rider to lean the front section of the vehicle into a corner while the rear wheels remain planted. The resulting inward shift of the center of gravity effectively counteracts centrifugal force. Engineering data indicates this pivot steering trike design reduces the risk of inner wheel lift and tipping compared to static frames. Furthermore, the pivot joint allows the vehicle to adapt to uneven terrain, as the frame can flex independently of the rear module to maintain vertical alignment on slanted surfaces.
Dual-Mode Operational Logic
The U-750 includes a frame locking system that enables two distinct operational modes:
Fixed Mode: The pivot joint is mechanically secured, preventing lateral movement. In this state, the U-Trike U-750 functions as a standard rigid tricycle, providing maximum stability for users who require an upright posture or are carrying high-weight loads.
Tilting Mode: The pivot is unlocked, enabling lean-to-turn functionality. This mode is intended for increased maneuverability and higher-speed cornering, providing an agility profile closer to a two-wheeled vehicle while maintaining a three-wheel footprint.
Propulsion and Electronic Systems
The U-Trike U-750 Tilting Electric Trike is powered by a 48V 750W rear-mounted hub motor. To modulate power delivery, Addmotor integrated a high-precision torque sensor. This sensor measures mechanical force applied to the pedals in real-time, providing proportional motor assistance. This system aims to provide smoother power curves than cadence-based sensors, particularly during the shifts in balance required for tilting maneuvers.
Energy storage is provided by a 48V 20Ah Samsung lithium-ion battery. The battery is UL-2271 certified, ensuring electrical and thermal safety. The manufacturer lists an operating range of 40 to 85 miles per charge, contingent upon environmental conditions and the selected pedal-assist level. The EB 2.0 electronic platform manages seven levels of assistance and a 1/2-twist variable-speed throttle.
Frame and Load Specifications
The U-750 frame is constructed from 6061 aluminum alloy, selected for its resistance to torsional stress. The vehicle utilizes a “mullet” tire configuration, featuring a 24″ x 4.0″ front tire and 20″ x 4.0″ rear tires. The 4.0-inch width increases the contact patch with the ground, which Addmotor reports provides higher friction and a more controlled leaning experience than thin-tire tilting models.
Suspension is handled by an Addshox oil spring fork with 80mm of travel. The braking system consists of mechanical disc brakes on all three wheels. A manual parking brake is integrated into the handlebar assembly to lock the vehicle vertically when stationary. The U-750 has a net weight of 110 lbs (50 kg) and a total payload capacity of 450 lbs, supporting a 350 lb rider and 100 lbs of rear cargo.
Integrated Safety Systems
The vehicle includes the EB 2.0 5-in-1 lighting module, which integrates brake lights, turn signals, hazard lights, and running lights into a single unit. Riding telemetry—including PAS status, motor output, velocity, and battery voltage—is monitored via a 5-inch handlebar-mounted LCD.
