The HEXEH QS180 8000W Mid Drive Motor Tricycle Kit paired with the Far Driver ND721200 Controller represents a robust solution for electric tricycle conversions or builds demanding high torque and reliability. Designed for commercial applications, heavy-duty cargo transport, or riders navigating challenging terrains, this system combines industrial-grade engineering with user-centric features. At its core lies the QS180 mid-drive motor, a 72V behemoth capable of delivering 8000W peak power, while the accompanying ND721200 controller ensures precise management of energy distribution.
Power and Performance
Central to the kit’s appeal is its ability to handle sustained high-load scenarios. The 72V architecture provides a foundation for consistent voltage delivery, crucial for maintaining speed and torque under strain. With a continuous power rating of 3000W (3kW) and a peak output of 8000W, the motor caters to applications where traditional hub motors might falter, such as steep inclines or heavy payloads. Riders transitioning from lower-powered systems often highlight the immediacy of the torque response, particularly when accelerating from standstill or tackling gradients. One user noted, “The pickup feels almost instantaneous, even with a fully loaded trike, which makes navigating urban hills far less daunting.”
The mid-drive configuration contributes to this performance. By driving the crankset directly, the motor leverages the tricycle’s existing gearing, allowing for efficient power transfer and reduced strain on the drivetrain compared to hub motors. This design choice also centralises weight distribution, improving handling—a critical factor for three-wheeled vehicles where stability is paramount.
Thermal Management and Efficiency
Heat dissipation remains a persistent challenge in high-output electric drives. HEXEH addresses this through a combination of passive cooling fin design on the motor and intelligent thermal regulation via the Far Driver controller. The latter employs real-time temperature monitoring to adjust output, preventing overheating without abrupt power cuts. Enthusiasts appreciate this subtlety; as one rider remarked, “There’s no sudden drop in power on long climbs—just a gradual taper that still leaves enough assist to keep momentum.”
Efficiency gains are further bolstered by the controller’s sinusoidal wave technology, which minimises torque ripple. This results in smoother acceleration and reduced mechanical noise, a feature frequently mentioned in user experiences. “It’s surprisingly quiet for something this powerful,” observed a cargo trike operator, “and the vibration-free operation means less wear on components over time.”
Controller Capabilities
The Far Driver ND721200 serves as the system’s brain, offering programmability through Bluetooth or CAN bus interfaces. This flexibility allows fine-tuning of parameters like torque curves, regenerative braking strength, and speed limits—a boon for mechanics tailoring setups to specific use cases. Commercial users particularly value the ability to create custom profiles for different load scenarios, from empty runs to maximum cargo capacity.
Built-in protection mechanisms cover over-voltage, under-voltage, over-current, and short circuits. These safeguards not only prolong component lifespan but also enhance safety during abrupt load changes or electrical faults. “Having that peace of mind when operating in wet conditions or pushing the system hard is invaluable,” shared a delivery service operator.
Installation and Compatibility
Weighing 18.5kg, the motor demands a sturdy frame mount, preferably on steel or reinforced aluminium frames. Compatibility with standard bicycle bottom brackets simplifies integration, though the high torque output necessitates robust chain retention solutions. Many users recommend pairing the system with a premium-quality chain and sprockets to handle the power transmission.
The controller’s compact form factor allows discreet placement, while its IP65 rating ensures resilience against water and dust ingress—a necessity for all-weather operations. Wiring harnesses are reportedly well-labelled, though some installers suggest adding supplementary cable management for complex builds.
Real-World Applications
In practical use, the kit excels in scenarios demanding both power and endurance. Food delivery riders report reduced journey times across hilly routes, attributing this to the motor’s ability to sustain higher speeds under load. Meanwhile, adaptive trike users praise the smooth low-speed control, which aids precise manoeuvring in crowded areas.
The system’s regenerative braking functionality garners particular praise from those covering long daily distances. By recovering energy during descents or stops, it extends range—a critical factor given the high power consumption inherent to 8000W systems. “On mixed routes with frequent stops, the regen effectively adds about 10-15% to my range,” noted a courier.
User Impressions
Feedback consistently highlights the balance between raw power and rideability. While the sheer output potential dominates initial impressions, longer-term users emphasise refinement. The lack of cogging torque at low speeds makes manual pedalling unassisted by throttle feel natural, a detail appreciated by riders who occasionally switch between electric and mechanical propulsion.
Durability under sustained use receives frequent mention, with several operators logging over 5,000 miles without performance degradation. Maintenance requirements appear minimal beyond routine chain lubrication and occasional torque arm inspections.
Considerations
Prospective users should note the system’s power demands necessitate high-capacity battery packs—ideally 72V 30Ah or larger—to fully utilise its capabilities. While suitable for road-legal applications when appropriately restricted, the kit’s unbridled output far exceeds UK e-bike regulations, necessitating careful configuration for public road compliance.
In essence, the HEXEH QS180 with Far Driver ND721200 Controller delivers industrial strength in a adaptable package. It bridges the gap between conventional e-bike components and light electric vehicle systems, offering expandability for those needing commercial-grade performance without custom engineering.
