EMotorad X3: Integrated 250W BLDC Hub Drive & 36V Lithium-Ion Power System
The EMotorad X3 is an urban-centric electric cycle engineered with a robust 250W BLDC rear hub motor and an integrated 36V 7Ah Lithium-Ion battery, delivering an efficient 40 km range and a top speed of 25 km/h. Its high-tensile steel frame and Shimano 7-speed drivetrain, complemented by a 5-level pedal assist system, offer a blend of durability and intuitive electric propulsion for daily commuting.
Quick Answer
The EMotorad X3 offers a balanced integration of 250W electric propulsion and reliable mechanical components, making it an ideal choice for efficient and dependable urban electric mobility.
✓Efficient 250W BLDC Rear Hub Motor with Hall Sensor Technology
✓Integrated 36V 7Ah (252Wh) Lithium-Ion Battery for 40 km Range & Removable Design
✓Durable High Tensile Steel Frame, 100mm Front Telescopic Suspension, and Dual Disc Braking
The EMotorad X3 is a sharp, matte-white entry into urban e-cycling. It’s perfect for city commuters who want simplicity without breaking the bank. With its 250W BLDC hub motor and removable 36V 7Ah battery, it’s designed for efficiency on flat roads. Buy this if you need a reliable, steel-framed daily driver for short office runs or campus commutes. However, avoid it if you require long-range endurance or integrated safety lights; its 252Wh capacity is strictly tailored for shorter, breezy urban hops.
✓ Who Should Buy
- •Urban commuters prioritizing efficiency and low-maintenance electric assist for daily travel.
- •First-time e-bike users seeking a dependable and easy-to-operate model with proven components (Shimano gears, disc brakes).
- •Riders needing a removable battery for convenient charging in apartments or offices.
✕ Who Should Avoid
- •Off-road enthusiasts or riders requiring advanced torque sensing for highly varied terrain (due to cadence sensor and no torque spec).
- •Users who require higher payloads or extended ranges beyond 40 km without recharging.
- •Riders seeking premium smart features like GPS, mobile app connectivity, or advanced telemetry.
Product Overview
The EMotorad X3 redefines urban commuting with its meticulously engineered electric drivetrain and robust cycling infrastructure. At its core is a 250W BLDC (Brushless DC) hub motor strategically positioned in the rear wheel, providing direct and efficient power delivery with a maximum assisted speed of 25 km/h, compliant with Indian regulations. This motor features a Hall sensor for precise commutation and smooth acceleration, seamlessly integrating with the rider's input.
Powering the X3 is a 36V nominal voltage, 7Ah (252Wh) Lithium-Ion battery pack, elegantly mounted on the downtube. This removable battery design facilitates convenient off-bike charging, taking approximately 3-4 hours for a full charge. A sophisticated Battery Management System (BMS) ensures optimal cell balancing and comprehensive protection against over-voltage, under-voltage, over-current, short-circuit, over-temperature, and deep discharge, safeguarding the longevity and performance of the power unit.
The drivetrain incorporates a reliable Shimano 7-speed gear system, operated via a thumb shifter, allowing riders to adapt to varied urban topographies. Complementing the electric assist, the X3 features 5 distinct pedal assist levels controlled by a cadence sensor, along with a full throttle option for effortless cruising. This synergistic design provides riders with versatile control over their riding experience.
Driving comfort and safety are paramount. The EMotorad X3 is built on a durable high-tensile steel diamond frame, designed to withstand the rigors of daily urban use. It features a responsive front telescopic fork offering 100mm of travel, effectively absorbing road imperfections and enhancing ride quality. Braking confidence is assured by front and rear disc brakes, equipped with a motor cut-off safety feature that instantly disengages power upon brake application. The 27.5-inch wheels fitted with tubed tires provide a balanced blend of agility and stability for city streets. An integrated LCD display provides essential telemetry including speed, state-of-charge (SOC), odometer, and trip distance, alongside ride mode switching capabilities, enhancing the overall user interface.

Engineering Analysis
The EMotorad X3 is engineered for optimal performance within its urban commuter segment, demonstrating a thoughtful integration of electrical and mechanical systems. The 250W BLDC rear hub motor, while not specifying peak torque, is paired with a 7-speed Shimano drivetrain. This combination allows riders to leverage mechanical advantage through gearing, compensating for varied inclines and load conditions, enhancing overall system efficiency despite the absence of a torque sensor. The Hall sensor-based commutation ensures smooth motor operation and precise power delivery across its 5 pedal-assist levels, with throttle support providing immediate on-demand power.
The 36V 7Ah Lithium-Ion battery, equating to 252Wh, is a critical component for the X3's rated 40 km range. This range efficiency translates to approximately 6.3 Wh/km (252Wh / 40km), which is a competitive figure for urban e-cycles, indicative of efficient motor calibration and moderate average speed usage. The removable downtube mounting improves user convenience for charging and security. Crucially, the embedded Battery Management System (BMS) provides comprehensive protection (over-voltage, under-voltage, over-current, short-circuit, over-temperature, deep discharge), significantly extending the battery's lifecycle and ensuring rider safety, a key engineering consideration.
Vehicle dynamics are enhanced by the front telescopic fork suspension, offering 100mm of travel. This significant travel depth is effective in mitigating shocks from potholes and uneven urban surfaces, improving rider comfort and control. The high-tensile steel frame provides a robust structural foundation, capable of supporting a maximum payload of 100 kg, ensuring durability for daily use. The braking system, featuring front and rear mechanical disc brakes, provides consistent and strong stopping power across various weather conditions. The integrated motor cut-off feature on brake activation is a vital safety mechanism, instantly disengaging power to prevent unintended acceleration and ensure rapid deceleration.
The 27.5-inch wheel size is a strategic choice, offering a balance between maneuverability in tight urban spaces and stability at speed, contributing to a confident riding experience. While detailed IP ratings are not provided, the water resistance specified for environmental ratings suggests a degree of protection against ingress, although precise technical limits remain undisclosed. The passive cooling for the battery and air cooling for the motor are standard for this power class, efficiently managing thermal loads under typical urban operating conditions.
