  • •Recreational riders seeking a reliable, low-maintenance e-bike for mixed-terrain use, benefiting from the 100mm front suspension.
  • •First-time electric cycle owners desiring a technically sound yet user-friendly experience with comprehensive battery protection and clear display diagnostics.
  • •Individuals valuing practical additions such as included fenders, rear carrier, and kickstand for enhanced utility.

✕ Who Should Avoid

  • •Extreme off-road mountain bikers requiring full suspension, hydraulic disc brakes, or significantly higher motor torque/peak power.
  • •Riders prioritizing a lightweight folding e-bike for multi-modal transport where portability is paramount.
  • •Users who require advanced smart connectivity features like mobile app control, GPS tracking, or OTA updates.
Product Overview
The EMotorad T-Rex Pro, launched in 2024, redefines the electric cycle segment with its dual-purpose design for urban commuting and all-terrain exploration. Constructed with a resilient Aluminium Alloy 6061 hardtail MTB frame, available in 27.5 or 29-inch wheel sizes, it weighs a lean 20 kg. Propulsion comes from a 250W BLDC rear hub motor, providing a top speed of 25 km/h, complemented by a Shimano Altus 7-speed gear system controlled via a thumb shifter, and 5 levels of pedal assist alongside full throttle support. The energy source is a removable 36V 13Ah (468Wh) Lithium-Ion battery, discreetly mounted on the downtube, capable of delivering up to 70 km of range with pedal assist or 45 km on throttle alone. Charging is facilitated by a 100-240V AC input charger, achieving 80% charge in approximately 4.6 hours and a full charge in 5-7 hours. Rider comfort and control are enhanced by a 100mm travel front fork suspension with lockout, mechanical disc brakes with motor cut-off, and 2.25-inch tubeless nylon tires mounted on double-wall aluminium alloy rims. The integrated lighting system includes headlight, taillight, brake light, and turn signals, further enhancing safety. Essential ride data is presented on a backlit Handlebar Integrated LCD (Cluster i13), displaying speed, SOC, range, odometer, and trip meter. The T-Rex Pro also features a rear carrier, fenders, kickstand, and BIS certification, ensuring a complete and reliable package for the discerning rider.

Engineering Analysis
The EMotorad T-Rex Pro exhibits a well-engineered architecture designed for robust performance and rider safety. The powertrain is centered around a 250W BLDC (Brushless DC) rear hub motor, which is an efficient and low-maintenance solution for electric cycles. This configuration, coupled with a responsive cadence sensor, offers five levels of pedal assist and a full throttle mode, allowing for flexible power delivery up to the regulated 25 km/h maximum speed. The integration of a Shimano Altus 7-speed mechanical drivetrain via a thumb shifter provides optimal gear ratios for varying gradients and rider effort, enhancing overall efficiency and range by minimizing motor strain. The energy storage system is a 36V 13Ah (468Wh) Lithium-Ion battery, strategically housed within the downtube. This placement lowers the center of gravity, improving vehicle dynamics and handling stability, particularly crucial for an 'All-Terrain' application. The battery is removable for convenient charging and is safeguarded by a comprehensive Battery Management System (BMS) that actively monitors and protects against over-voltage, under-voltage, over-current, short-circuit, over-temperature conditions, and deep discharge. This proactive protection ensures battery longevity and operational safety. The chassis and suspension dynamics are founded on a lightweight yet robust Aluminium Alloy 6061 hardtail MTB frame, contributing to the cycle's manageable 20 kg weight. The 100mm travel front fork suspension, equipped with a lockout mechanism, is critical for absorbing impacts on uneven surfaces, while the lockout feature allows for efficient power transfer on smooth roads, preventing 'bobbing'. The choice of 27.5 or 29-inch wheels, shod with 2.25-inch tubeless nylon tires and mounted on double-wall aluminium alloy rims, provides a balance of rolling efficiency, grip, and puncture resistance across diverse terrains. Braking performance is handled by reliable mechanical disc brakes on both front and rear wheels, featuring an essential motor cut-off function that instantaneously disengages power when brakes are applied, thereby shortening stopping distances and enhancing rider control and safety. The integrated electronics and controls are managed via a Handlebar Integrated LCD (Cluster i13) which provides critical real-time telemetry including speed, state of charge (SOC), estimated range, odometer, and trip meter, all with backlight for visibility. The inclusion of integrated lighting (headlight, taillight, brake light, and turn signals) is a significant safety enhancement, providing visibility and communication in all riding conditions. The EMotorad T-Rex Pro’s design adheres to practical considerations with an adjustable seat, rear carrier, fenders, and kickstand, underscoring its utility for daily commutes and recreational rides while maintaining a sleek aesthetic with its pearl/luxury car-grade paint finish. The BIS certification further confirms its adherence to Indian quality and safety standards, particularly concerning electrical isolation and water resistance.
