Merida eBig Nine 675 Electric Mountain Bike Review

The Merida eBig Nine 675 holds a distinct spot in the crowded electric mountain bike arena, combining robust engineering with practical features tailored to serious off-road enthusiasts. Designed specifically for mountain biking, this e-bike balances powerful assistance and a rugged build to support riders across a wide spectrum of heights and weights. On paper, it's clear this model aims to deliver a dependable and versatile ride, with a notable 250 W mid-drive motor and a substantial lithium-ion battery backing it. In this review, we'll detail how those specs come together, what they imply for real-world use, and who could benefit most from its capabilities.

Technical Specifications and Features Overview

Starting with its foundation, the eBig Nine 675 features a durable aluminum frame, weighing approximately 51.37 pounds, which provides a solid yet manageable presence on mountainous terrain. The 29-inch wheel size, paired with pneumatic, off-road tires of 2.2 inches in width, ensures good ground contact and improved obstacle handling. At the heart of its propulsion system lies a 250 W mid-drive motor delivering reliable torque of 85 Nm, consistent with its Class 1 rating, allowing pedal-assist speeds up to 20 mph.

The bike relies on a 750 Wh lithium-ion battery voltage rated at 36 V, which, based on its engineering data, offers a practical range of between 30 and 70 miles depending on conditions and rider input. This battery is also removable with a locking mechanism, adding convenience for charging and security. Although it lacks fast-charging support, the inclusion of a centrally located charging port makes recharging straightforward. Its drivetrain includes a 12-speed SRAM NX Eagle derailleur with a 10-50 tooth gear range, enabling optimal gear transitions for different terrain challenges.

Design & Build

On the surface, the eBig Nine 675 presents as a thoughtfully designed mountain e-bike built to perform. The step-over frame style favors versatility and ease of mounting, suiting a broad rider height range from 4'11" to 6'8". Its weight capacity of nearly 309 pounds confirms the frame's sturdiness and broad usability. Front suspension is highlighted by an air-type fork with nearly 4 inches of travel (3.94 inches), which will absorb shocks and rough terrain effectively. However, the absence of rear suspension defines it as a hardtail mountain bike. The inclusion of ergonomic grips and an adjustable saddle height aims to enhance rider comfort during extended use.

Performance

The mid-drive motor's continuous power rating at 250 watts and peak torque of 85 Nm provide a well-balanced level of support for trail climbing and steady cruising. Coupled with three selectable pedal assist levels, riders can adjust their experience effortlessly, tailoring power output to save battery or boost performance. While the bike does not include a throttle mode or cruise control, it compensates with a walk-assist feature ideal for navigating challenging starts or rough stretches. The bike's disc hydraulic brakes, paired with 7.09-inch rotors, promise firm control and stopping power essential for mountain descents, and they are UL/CE safety certified; an authoritative mark of quality and trust.

Display and Electronics

The bike's LCD, centrally mounted and backlit for visibility, delivers real-time information such as speed, distance (odometer and trip meter), battery status, and integrates with a smartphone app via Bluetooth connectivity. This smart integration supports ride data logging and provides riders with a modern edge to monitor and improve their cycling experience. While it lacks GPS tracking and navigation, the presence of these core digital tools equips riders well for both casual rides and more technically demanding outings. The bike is designed with user-friendliness in mind, though it omits USB charging or advanced connectivity like Wi-Fi.
