Description
Eunorau FLASH
The EUNORAU FLASH is not just an e-bike; it is a highly engineered, customizable utility platform. Swapping out standard configurations for total modular freedom, the FLASH frame is built from heavy-duty 6061 aluminum alloy with specific, integrated mounting terminals. This allows riders to scale up their battery capacity, select their preferred motor configuration, and bolt on specialized accessories seamlessly.
Industry-First Triple-Battery Ecosystem : Eunorau FLASH
The defining breakthrough of the EUNORAU FLASH is its native support for three independent batteries operating simultaneously, eliminating range anxiety forever:
-
Standard Battery: A frame-integrated 52V 16Ah base pack (included).
-
Top-Tube Expansion: An optional bolt-on 52V 17Ah battery terminal.
-
Down-Tube Expansion: An optional top-mounted 52V 21Ah battery terminal.
When fully loaded with all three packs, the system forms a massive 52V 54Ah (2,808Wh) Samsung-cell reservoir, feeding an intelligent Battery Management System (BMS). This configuration yields an incredible 354 km (220 miles) of continuous pedal-assist range or up to 170 km on pure electric throttle power.
Three Selectable Drivetrain Configurations
The FLASH platform utilizes a unified chassis that can be ordered in three entirely different motor layouts to suit your specific driving environment:
-
The Mid-Drive Monster: Driven by a 1000W Truckrun mid-drive motor outputting an earth-moving 220 Nm of peak torque. This configuration runs through a Shimano 8-speed drivetrain with integrated Shift Detection—instantly cutting motor power for milliseconds during gear changes to protect the chain and cassette from snapping under extreme load.
-
The AWD Predator: Employs Dual 750W hub motors (one front, one rear) to produce 1500W of continuous power and 184 Nm of dual-traction torque. This creates an electronic all-wheel-drive system that claws through deep sand, loose snow, and slick mud where single-motor bikes spin out.
-
The Urban Cruiser: A budget-conscious, low-maintenance 750W rear hub motor configuration (92 Nm torque) matched with a durable single-speed drivetrain, perfect for flat-land commuting and city errands.
Elite Utility & Passenger Architecture
Every iteration of the FLASH comes standard with highly sensitive torque sensors, meaning the motor mirrors your leg power proportionally for a completely natural ride and 30% greater energy efficiency over traditional cadence sensors.
To safely arrest its massive momentum and 200 kg (440 lbs) maximum payload, the bike is anchored by elite 4-piston hydraulic disc brakes clamped onto thick 180mm rotors. The Mid-Drive model is paired with an advanced full-suspension system—combining an EXSHO STRONG-DH 80mm front travel fork with a dual 290mm motorcycle-style rear spring setup—while rolling smoothly on ultra-stable 20″ x 4.0″ CST puncture-resistant fat tyres. A plush, extended dual-rider saddle effortlessly accommodates a companion with no drop in handling performance.
The Longest Range E-bike : Eunorau FLASH
The FLASH electric bike comes with three battery options. If a single battery isn’t enough, riders can add a second or a third battery. With all three batteries on board, the EUNORAU FLASH is said to achieve a range of 354 km (220 miles) on pedal assist 1. This long range makes it one of the longest traveling e-bikes in the industry.
Powerful and Stable Mid motor
It is a center-mounted drive which makes the bike’s center of gravity not change greatly, which greatly ensures the balance and stability of the bike.
It has superior waterproof performance and noise, and increases the practicality and stability of the motor. The motor has high-sensitivity torque sensor and speed sensor, which can realize precise control of the whole bike.
EXSHO STRONG-DH Fork
Front suspension fork features 80mm of travel, compression adjustment and lockout. It effectively absorbs most of the jarring bumps and shocks, especially on complicated and rugged routes, reducing your tiredness and allowing you to ride faster.
