Efficient 250W BLDC Rear Hub Motor with Hall Sensor technology, delivering a top speed of 25 km/h for urban and personal mobility.
Integrated 36V 10.4Ah (374Wh) Lithium-ion Battery with comprehensive BMS and cell balancing, offering up to 40 km PAS range and 500+ estimated charge cycles.
Durable Alloy 6061 Frame with 100mm front suspension, coupled with responsive dual disc brakes featuring motor cut-off, and an IP65 weather protection rating for enhanced safety and structural integrity.

The Hero Lectro F2i is a solid pick for urban commuters who value range over raw power. Its 36V 10.4Ah battery offers better endurance than entry-level models, paired with a sturdy 18-inch Alloy 6061 frame. Buy this if you want a reliable India-made e-MTB for long city rides and have a ground-floor charging spot. Avoid it if you require a removable battery for apartment charging or need high-torque for steep hills. It’s a smart, efficient cruiser, not a hardcore trail-breaker.

✓ Who Should Buy

  • Urban Commuters seeking an efficient, low-maintenance electric bicycle with reliable power assistance for daily travel.
  • Fitness Enthusiasts desiring pedal assistance for extended rides, varied terrains, or to reduce exertion on inclines.
  • Riders prioritizing robust safety features, including dual disc brakes with motor cutoff and comprehensive battery protection (BMS).
  • Individuals looking for an Indian-made, BIS-certified e-cycle with smart connectivity via Bluetooth and mobile app control.

✕ Who Should Avoid

  • Extreme Off-road Riders requiring full suspension, higher torque ratings, and specialized geometries for aggressive trail riding.
  • Long-distance Tourers needing significantly greater range (e.g., 80km+) without the convenience of frequent recharging, or removable batteries for extended expeditions.
  • Users requiring a foldable design for compact storage or seamless integration with multi-modal public transportation.
Product Overview
The Hero Lectro F2i is a 'Mountain E-Bike Smart' type electric cycle, meticulously crafted in India to cater to urban commute and personal mobility sectors. Its foundation is an 18-inch (45cm) Alloy 6061 frame, finished with water transfer decals for a premium aesthetic, while ensuring robust structural integrity. Powering the F2i is a 250W BLDC rear hub motor, equipped with Hall sensors for precise power modulation and achieving a regulated maximum speed of 25 km/h. Energy is supplied by a down-tube mounted 36V 10.4Ah (374Wh) Lithium-ion battery, which incorporates an advanced Battery Management System (BMS) with active cell balancing to maximize its estimated 500+ cycle life and ensure safe operation. The drivetrain features a versatile 21-speed Shimano gear system, managed by responsive trigger shifters, allowing riders to adapt to varied terrains. Combined with 3 levels of pedal assist and throttle support, along with a cadence sensor, the F2i offers a dynamic riding experience. For rider comfort, it includes front suspension with 100mm travel and 27.5-inch wheels fitted with 2.125-inch tube tires on double-wall alloy rims. Safety is paramount, with front and rear disc brakes incorporating a motor cut-off function, guaranteeing immediate power cessation upon braking. The integrated LED display with RFID key provides real-time speed and State of Charge (SoC) readouts, while Bluetooth connectivity and mobile app control add a layer of smart functionality to monitor and manage your ride. The F2i's electrical components boast an IP65 ingress protection rating, safeguarding against dust and water, and it adheres to BIS certification standards, reinforcing its reliability and safety.

Engineering Analysis
The Hero Lectro F2i demonstrates a well-balanced engineering approach for its intended application. The core powertrain comprises a 250W BLDC rear hub motor, which, while not specified for peak torque, is inherently tuned for efficient acceleration and sustained speed within urban environments up to its 25 km/h limit. The motor's Hall sensor integration ensures smooth, responsive power engagement for both throttle and pedal-assist modes, optimizing rider effort. The 36V 10.4Ah (374Wh) Lithium-ion battery system is a critical component, featuring a sophisticated BMS that provides essential over-voltage, under-voltage, over-current, short-circuit, over-temperature, and deep discharge protections, significantly enhancing cell longevity and operational safety. The specified 5-6 hour charging time via a 72W charger ensures a full energy replenishment for its 40 km PAS range. The lightweight Alloy 6061 frame, combined with an 18-inch geometry, offers a robust yet agile platform, well-suited for city riding and light trails. The 100mm front suspension contributes to improved ride comfort and shock absorption over uneven surfaces, enhancing control. Braking performance is achieved through mechanical disc brakes on both wheels, critically integrated with a motor cut-off switch for instantaneous power disengagement, thereby reducing stopping distances and improving overall safety. The 21-speed Shimano derailleur system broadens the bike's utility, enabling riders to efficiently manage gradients and speeds independent of electric assistance. Thermal management relies on passive air cooling for both the motor and battery, suitable for its rated power and typical operating conditions (0°C to 45°C). The IP65 enclosure rating for electrical components signifies a high degree of resistance against dust ingress and low-pressure water jets, making the F2i a resilient option for diverse weather conditions. BIS certification further underscores its adherence to national quality and safety standards.
