Its Aluminium Alloy hardtail frame, paired with a 100mm front telescopic fork and mechanical disc brakes, ensures a robust and controlled riding experience across urban and mixed terrains, certified by BIS for safety.
Quick Answer
The EMotorad T-Rex+ V3 offers an optimal balance of sustained power delivery, robust chassis dynamics, and comprehensive battery protection for diverse riding conditions, supported by its 468Wh Li-Ion energy system.
✓Efficient 250W BLDC Rear Hub Motor with 5 Pedal Assist Levels and Throttle Support for versatile power delivery.
✓Long-lasting 36V 13Ah (468Wh) Removable Lithium-Ion Battery, offering up to 50 km PAS range with integrated BMS and passive cooling.
✓Durable Aluminium Alloy Hardtail Frame, 100mm Front Telescopic Suspension, and precise Mechanical Disc Brakes for superior control and comfort across varied surfaces.
The EMotorad T-Rex+ V3 is a top pick for riders seeking a rugged hardtail MTB that balances city commuting with off-road agility. Its 36V 13Ah removable battery packs a punchy 468Wh, outlasting many standard 250W hub motor e-cycles. Buy this if you want a lightweight 20kg aluminium alloy frame with a stylish Crimson Black or Olive Fade matte finish. However, skip it if you require a foldable frame or pre-installed integrated lighting and fenders, as this model prioritizes core performance over urban utility accessories.
✓ Who Should Buy
- •Urban commuters seeking an eco-friendly, assisted travel solution for mixed terrains, valuing range and reliability.
- •Recreational riders desiring a durable electric hardtail MTB for light trails, weekend adventures, and fitness.
- •Individuals prioritizing a cost-effective e-bike with essential safety, performance features, and BIS certification.
- •Users looking for a maintenance-friendly e-cycle with a removable battery and integrated display.
✕ Who Should Avoid
- •Professional mountain bikers requiring advanced full suspension systems, hydraulic disc brakes, or higher peak torque for extreme trails.
- •Riders needing extensive smart connectivity features like GPS navigation, mobile app control, or remote diagnostics.
- •Users prioritizing fast charging capabilities or integrated cargo solutions as a standard offering for heavy-duty touring.
Product Overview
The EMotorad T-Rex+ V3 stands as a robust electric cycle, meticulously designed for both urban commuting and light off-road excursions. Its foundation is an Aluminium Alloy hardtail MTB frame, finished in a matte Crimson Black or Olive Fade, providing both structural integrity and a refined aesthetic. Powering this e-cycle is a 250W BLDC rear hub motor, which delivers assistive thrust up to 25 km/h, perfectly complemented by 5 levels of pedal assist and a throttle for dynamic control. The energy source, a removable 36V 13Ah (468Wh) Lithium-Ion battery, is discreetly integrated into the downtube, contributing to a balanced center of gravity and offering an impressive 50 km range under PAS conditions. Gear transitions are managed by a reliable 7-speed Shimano Tourney system with a thumb shifter, ensuring smooth adaptation to varied gradients. Mechanical disc brakes on both the front and rear wheels provide consistent stopping power, enhanced by a motor cut-off safety feature. Comfort and control are further assured by a 100mm travel front telescopic suspension fork and 1.95-inch tubeless tires available on 26, 27.5, or 29-inch aluminium alloy spoked wheels. The user interface is facilitated by an intuitive LCD (Cluster i8) display, providing essential metrics like speed, battery state-of-charge (SOC), odometer, and trip meter, with backlight functionality for visibility. Essential safety features include integrated headlight, taillight, horn, and comprehensive electrical protections for the battery and motor, all contributing to a reliable and secure riding experience.

Engineering Analysis
The EMotorad T-Rex+ V3 represents a strategically engineered electric cycle, balancing power, durability, and rider ergonomics for its intended urban/off-road application. Its vehicle dynamics are anchored by a lightweight 20 kg Aluminium Alloy hardtail frame, which offers an optimal stiffness-to-weight ratio crucial for responsive handling in diverse conditions. The integrated front telescopic fork with 100mm travel effectively mitigates shock transmission from uneven terrains, providing a more comfortable and controlled ride without the added complexity and weight of a full-suspension system.
At the core of its propulsion is a 250W BLDC (Brushless DC) rear hub motor, a standard for Indian regulatory compliance, ensuring efficient power delivery. This motor, featuring a Hall sensor for precise commutation, is air-cooled for thermal management under sustained use. While specific torque figures are not provided, its rated power of 250W, combined with 5 pedal assist levels and throttle support, indicates ample capability for reaching the governed 25 km/h maximum speed and handling moderate inclines, especially when paired with the 7-speed Shimano Tourney drivetrain. The cadence sensor-based pedal assist system offers a reliable and cost-effective approach to power modulation.
Energy storage is managed by a 36V 13Ah (468Wh) Lithium-Ion battery pack, strategically mounted within the downtube. This placement lowers the e-bike's center of gravity, enhancing stability and handling characteristics. The removable battery design adds convenience for charging and security. A crucial aspect is the integrated Battery Management System (BMS), which provides comprehensive protection features including over-voltage, under-voltage, over-current, short-circuit, over-temperature, and deep discharge protection. This robust BMS, coupled with passive cooling, ensures battery longevity and operational safety. The 468Wh capacity translates to an estimated 50 km range under pedal assist, signifying a commendable energy efficiency for daily commutes and recreational rides.
Stopping power is delivered by mechanical disc brakes on both front and rear wheels. This system offers consistent and reliable braking performance across various weather conditions, surpassing rim brakes in efficiency and modulation. The motor cut-off feature upon brake engagement is a critical safety interlock, instantly disengaging power to ensure rapid deceleration. The choice of tubeless 1.95-inch tires across multiple wheel sizes (26/27.5/29 inches) on Aluminium Alloy spoked rims enhances puncture resistance and provides versatility for different rider preferences and terrain types. The Stem Integrated Cluster i8 LCD display offers vital telemetry, ensuring riders are well-informed of their speed, battery state-of-charge, and ride metrics, contributing to an informed and controlled riding experience. Furthermore, BIS certification and electrical isolation confirm adherence to national safety standards.
