Eunorau FLASH: The Industry Leader in Range and Raw Torque

The Longest Traveling E-Bike Ever Built

The Eunorau FLASH is a marvel of electric bike engineering, designed for those who want to eliminate range anxiety forever. While most e-bikes top out at 40-60 miles, the FLASH features a revolutionary triple-battery system that can push your journey to an incredible 220 miles on a single charge. Whether you are a long-distance tourer, a daily commuter, or an off-road explorer, the FLASH provides more freedom than any other bike in its class.

Three Motor Configurations for Ultimate Control

Tailor your power to your lifestyle. The FLASH is available in three distinct drive types:

• The Mid-Drive Monster: Featuring a Truckrun 1000W Mid-Drive motor with a staggering 220 Nm of torque. This configuration includes an 8-speed Shimano drivetrain with shift detection and a full-suspension frame for elite climbing and technical trail performance.

• The AWD Predator: Dual 750W motors (1500W total) for unmatched traction in snow, sand, and mud.

• The Urban Cruiser: A reliable 750W rear hub motor for smooth, efficient city commuting.

Elite Components & Heavy-Duty Utility

• 4-Piston Hydraulic Stopping Power: To control its massive torque and 440 lb payload capacity, the FLASH is equipped with 4-piston hydraulic disc brakes. These offer superior heat dissipation and sensitive, reliable braking force in the harshest conditions.

• Advanced Full Suspension: The mid-drive model features the EXSHO STRONG-DH 80mm front fork and a unique dual rear spring suspension (290mm), providing a "cloud-like" ride over rough terrain and city potholes.

• Smart Visibility: Integrated front and rear lights are powered by the main batteries. The automatic taillight features a braking sensor, illuminating instantly when you slow down to warn motorists behind you.

• Digital Ecosystem: The BC281 LCD display connects via Bluetooth to the "EUNORAU GO" App, offering calorie tracking, trip records, and social networking features.

Frequently Asked Questions

How does the triple battery system work?

The FLASH frame is uniquely designed to house three separate batteries: one standard 16Ah unit, one in the top tube (21Ah), and one in the down tube (17Ah). The system intelligently draws power to provide an industry-leading 220 miles of range. You can start with one and add more as your adventure needs grow!

What makes a "Mid-Drive" motor better for hills?

The Truckrun 1000W mid-drive motor leverages the bike's 8-speed Shimano gears. This allows you to shift into a lower gear for a massive mechanical advantage, resulting in 220 Nm of torque. It can climb steeper inclines than almost any hub motor bike on the market while keeping the center of gravity perfectly balanced.

Is this bike safe for two riders?

Yes! The FLASH features a plush, extended saddle and a high payload capacity of 440 lbs. The 1000W motor is more than capable of hauling a passenger without sluggish acceleration. The 4-piston hydraulic brakes provide the extra stopping power you need when carrying a companion.

What is "Shift Detection"?

Integrated into the mid-drive motor system, shift detection momentarily cuts power to the motor the instant you click the gear shifter. This prevents the motor from "slamming" the chain and derailleur while under high torque, ensuring smooth gear changes and a much longer lifespan for your drivetrain.

How do I charge three batteries at once?

The FLASH comes with a high-speed 4.0A smart charger, which is twice as fast as standard 2.0A chargers. While the batteries can be charged on the bike, they are also removable, allowing you to charge them separately at home or in the office for convenience.
