✓Durable Alloy 6061 Frame with a rigid suspension system, paired with 27.5-inch wheels and dual disc brakes for reliable urban navigation.
✓Smart Connectivity via Bluetooth and mobile app control, offering ride history access and intuitive ride mode switching via an LED display with RFID key.
The Hero Lectro C5i is a sleek choice for city riders seeking a stealthy e-cycle look thanks to its 36V 5.8Ah in-tube battery. Its lightweight 18.5" Alloy 6061 frame and 250W rear hub motor make it perfect for quick, flat urban dashes. Buy this if you want a reliable, smart-looking commuter for short distances. However, avoid it if you have a long daily commute or live in a high-rise without charging access, as the non-removable battery requires bringing the whole bike to a power outlet.
✓ Who Should Buy
- •Urban commuters prioritizing a reliable and low-maintenance electric cycle for daily travel distances up to 25 km.
- •Riders seeking an e-bike with robust safety features, including comprehensive battery protection (BMS) and disc brakes with motor cutoff.
- •Individuals looking for an Indian-made electric cycle with smart connectivity for ride data tracking and basic remote management.
- •First-time e-bike users who prefer a straightforward, single-speed drivetrain and intuitive pedal-assist/throttle operation.
✕ Who Should Avoid
- •Enthusiasts requiring higher power output, multi-gear transmissions, or advanced suspension systems for off-road trails or challenging gradients.
- •Users needing extended ranges beyond 25 km or quick-swap/removable batteries for extended riding sessions or convenience.
- •Riders who prioritize lightweight folding mechanisms for extreme portability or complex integrated lighting systems for night riding.
Product Overview
The Hero Lectro C5i, an Indian-origin electric cycle launched in 2021, is purpose-built for urban commute and personal mobility. Its core architecture features a 470mm (18.5-inch) Alloy 6061 frame, finished with water transfer decals, designed for a rigid and responsive ride. Power is delivered by a 250W BLDC (Brushless DC) rear hub motor, equipped with a Hall sensor for precise control, enabling a maximum assisted speed of 25 km/h.
The energy source is a 36V, 5.8Ah (208Wh) Lithium-ion battery, discreetly integrated within the frame (in-tube mounting). This battery system incorporates a sophisticated Battery Management System (BMS) with critical protections against over-voltage, under-voltage, over-current, short-circuit, over-temperature, and deep discharge, ensuring both safety and an estimated cycle life of over 500 charges. The entire electrical enclosure boasts an IP65 rating, signifying robust resistance to dust and water ingress, crucial for diverse weather conditions. Charging takes approximately 3-4 hours via a 230V AC input, 72W proprietary charger.
Ride dynamics are controlled by a single-speed chain drive, supported by three levels of pedal assist (PAS) and a dedicated throttle, activated via a cadence sensor. Braking is handled by reliable front and rear disc brakes, which include a safety-critical motor cutoff feature. The cycle rolls on 27.5-inch wheels fitted with 2.0-inch tube tires and double-wall alloy rims for enhanced durability. Rider interface includes an LED display with an RFID key, providing real-time speed and State of Charge (SOC) indications, along with ride mode switching capabilities. Smart features like Bluetooth connectivity and a mobile app allow for ride history tracking and remote interaction. The C5i also features an immobilizer and a kickstand for added convenience and security, and comes BIS certified, ensuring adherence to national quality standards.

Engineering Analysis
The Hero Lectro C5i demonstrates a pragmatic engineering approach to urban e-mobility, focusing on efficiency, reliability, and safety.
Powertrain Architecture and Performance: At its core, the C5i utilizes a 250W BLDC rear hub motor. This motor type, known for its high efficiency and compact form factor, is optimally positioned for direct power transfer to the rear wheel. The integration of a Hall sensor ensures precise rotor position sensing, leading to smooth and efficient commutation, especially critical during initial acceleration and varied pedal-assist levels. While peak torque specifications are not provided, the 250W rated power is judiciously selected to meet the 25 km/h speed limit, making it fully compliant with Indian e-cycle regulations. Thermal management for the motor relies on passive air cooling, effective within its specified operating range of 0°C to 45°C.
Energy Storage and Management System: The 36V, 5.8Ah (208Wh) Lithium-ion battery is a key component, ingeniously mounted in-tube within the frame. This not only protects the battery from external elements but also contributes to the bicycle's streamlined aesthetics and balanced weight distribution. The integral Battery Management System (BMS) is comprehensive, offering essential multi-point protection: over-voltage (OV), under-voltage (UV), over-current (OC), short-circuit (SC), over-temperature (OT), and deep discharge. These protections are vital for extending the battery's estimated 500+ cycle life and ensuring operational safety. The IP65 rating for the battery enclosure guarantees resistance against dust ingress and low-pressure water jets, reinforcing its durability in varied urban environments. The 208Wh capacity, combined with the 250W motor, is optimized for the stated 25 km (PAS) / 20 km (Throttle) range, balancing energy density with practical urban use.
Chassis and Braking System Dynamics: The frame, constructed from Alloy 6061, provides a balance of strength and light weight, essential for a city commuter. Its rigid suspension setup, while not offering shock absorption, ensures direct power transmission and reduces maintenance, aligning with its urban application. The 27.5-inch wheels, paired with 2.0-inch tires and robust double-wall alloy rims, provide a stable and durable contact patch with the road. The braking system, featuring front and rear disc brakes, offers superior stopping power and consistency compared to rim brakes, particularly in wet conditions. Crucially, the motor cutoff on brake activation enhances safety by immediately disengaging power, reducing stopping distances and preventing unintended acceleration during braking.
Control and Interface: The LED display, complemented by an RFID key, offers a clear and straightforward interface for monitoring speed and State of Charge (SOC). The 3 pedal-assist levels and throttle mechanism provide flexible power delivery options. Bluetooth connectivity, coupled with mobile app control, allows for valuable data acquisition, such as ride history, enhancing the user's interaction with the vehicle's performance metrics and potentially facilitating remote diagnostics or future feature enhancements.
