✓Efficient 250W BLDC Rear Hub Motor with Hall Sensor for consistent power delivery and 25 km/h max speed.
✓High-capacity 36V 11Ah (410Wh) Lithium-ion battery featuring BMS, cell balancing, and a 55 km PAS range.
✓Durable Alloy 6061 frame (470mm) paired with 21-speed Shimano Trigger Shifters and front suspension for versatile ride dynamics.
✓Enhanced safety with front and rear 160mm disc brakes, incorporating motor cutoff, and IP65-rated electronics for all-weather reliability.
✓Integrated Bluetooth connectivity and mobile app control for a smart and connected riding experience.
The Hero Lectro F6i is a standout for urban commuters who prioritize convenience; that 410Wh semi-integrated battery is removable, making indoor charging a breeze. Its 18-inch Alloy 6061 frame offers a premium feel compared to entry-level steel models. Buy this if you need a reliable daily driver with decent range and the backing of Hero’s vast service network. However, avoid it if you require integrated lights or cargo racks, as this 'Mountain E-Bike' leans more towards a minimalist, sporty aesthetic than a utility hauler.
✓ Who Should Buy
- •Urban commuters seeking an efficient, low-maintenance daily transport solution with an assisted range of up to 55 km.
- •Riders looking for a comfortable e-bike featuring front suspension, multi-speed Shimano gearing, and disc brakes for varied city terrains.
- •Individuals prioritizing battery security (lockable, removable) and comprehensive electronic protection (BMS, IP65 rating, electrical isolation).
- •Environmentally conscious riders desiring a BIS-certified personal mobility vehicle for sustainable travel.
✕ Who Should Avoid
- •Off-road enthusiasts or hardcore mountain bikers requiring higher peak motor torque, advanced rear suspension, or wider, tubeless tires.
- •Users needing extended ranges significantly beyond 55 km on a single charge for very long commutes without charging access.
- •Riders who prefer hydraulic disc brakes or a torque sensor for a more immediate and intuitive pedal assist response.
Product Overview
The Hero Lectro F6i emerges as a meticulously engineered electric cycle, optimized for the demands of urban commuting and personal mobility. Its foundation is a resilient 470mm (18-inch) Alloy 6061 frame, finished with water transfer decals, guaranteeing both structural integrity and aesthetic appeal. Powering this e-bike is a sophisticated 36V 11Ah (410Wh) Lithium-ion battery, semi-integrated within the frame for enhanced protection and aesthetics. This power unit is not only removable and lockable but also features an advanced Battery Management System (BMS) with cell balancing, extending its estimated 500+ cycle life and backed by a 1-year warranty.
Propulsion is managed by a 250W BLDC rear hub motor, compliant with a maximum speed of 25 km/h, making it ideal for city regulations. The motor's Hall Sensor ensures smooth and responsive power delivery, seamlessly integrating with the rider's effort. The drivetrain boasts a 21-speed Shimano Trigger Shifter system, offering a wide gear ratio for tackling varying terrains and inclines with ease. Riders benefit from three levels of pedal assist and a convenient throttle for effortless cruising.
Charging the 410Wh battery takes approximately 6 hours via a 72W proprietary charger, connecting to a standard 230V AC input. Safety is paramount, with robust front and rear 160mm disc brakes providing reliable stopping power, complemented by a motor cutoff feature that instantly disengages power upon braking. The ride comfort is augmented by a front suspension system and 27.5-inch wheels fitted with 2.0-inch tube tires on double-wall alloy rims, ensuring durability and a stable ride.
Electronically, the F6i is designed for endurance, featuring an IP65 rating for its enclosure, safeguarding against dust and water ingress. Comprehensive protection features include over-voltage, under-voltage, over-current, short-circuit, over-temperature, and deep discharge protection for the battery. Thermal management is passively air-cooled, maintaining optimal operation within 0C to 45C. An intuitive LED display with backlight provides essential ride data like speed and battery SoC, alongside ride mode switching. Connectivity options include Bluetooth support and mobile app control, enhancing the user experience.

Engineering Analysis
The Hero Lectro F6i's engineering profile reveals a calculated design choice focusing on durability, efficiency, and rider safety within its target application. The `Alloy 6061` frame material provides an optimal strength-to-weight ratio for a premium mountain e-bike chassis, ensuring structural rigidity for urban and light trail use.
Vehicle Dynamics & Power Management: The heart of the F6i's propulsion is its `250W BLDC Rear Hub Motor`. While specific rated torque (Nm) is not provided, this motor configuration, combined with `Hall Sensor` technology, ensures smooth, linear power assistance, regulated to a maximum speed of `25 km/h` in compliance with Indian electric cycle standards. The `36V 11Ah (410Wh) Lithium-ion battery`, semi-integrated and removable, forms the core energy storage. Its `55 km (PAS)` range translates to an impressive energy efficiency of approximately `7.45 Wh/km` (410Wh / 55km), indicating optimized power delivery and minimal losses across the motor-controller-battery system. The inclusion of a robust `Battery Management System (BMS)` with `cell balancing` is critical for maximizing battery lifespan (rated `500+ cycles`) and ensuring stable performance under varying load conditions, while protection features (OV, UV, OC, SC, OT, Deep Discharge) safeguard the investment.
Drivetrain Architecture: The `21-speed Shimano` drivetrain with `Trigger Shifters` offers riders granular control over gear ratios, crucial for adapting to varying gradients and maximizing mechanical advantage, whether powered by the `250W motor` or pure pedal input. The presence of a `cadence sensor` ensures seamless and intuitive activation of the `3 pedal assist levels` and `throttle support`, making the transition between human and electric power fluid. The chain drive system is a proven, reliable method for power transfer.
Braking System and Safety: Safety is prioritized with `front and rear disc brakes` utilizing `160mm rotors`. Crucially, the `motor cutoff on brake` feature immediately disengages power when brakes are applied, significantly enhancing rider safety and control, especially during emergency stops. The `IP65 rating` for the electronic enclosure guarantees robust protection against dust ingress and water jets, ensuring operational reliability in diverse environmental conditions. Further electrical safety is confirmed by `BIS Certification` and explicit `electrical isolation`.
Thermal Management & Structural Components: The `Passive Air Cooling` strategy for both the motor and battery, designed for operating temperatures between `0°C and 45°C`, indicates a reliable thermal design suitable for typical urban climates. The `27.5-inch wheels` with `2.0-inch tube tires` and `double-wall alloy rims` provide a balance of agility, durability, and impact resistance for urban terrains.
