Eunorau | Flash

Overview

The Flash is a 20" electric bike available in a single mid-drive model (FLASH) and dual/rear motor variants (FLASH AWD & FLASH LITE). It combines strong motors, a modular three-battery system for extended range, wide 4.0" tires, hydraulic disc brakes, and a clear LCD display. Choose full-suspension for smoother off-road comfort or the hard-tail setup for a simpler, lighter ride.

Benefits

• Go farther between charges — a three-battery setup gives up to 220 miles of range, so you can ride longer routes without worrying about power.
• Ride more comfortably on rough roads — full-suspension FLASH absorbs bumps for less fatigue.
• Faster commutes and more route options — higher top speed on AWD/Lite models (up to 28 MPH) shortens travel time.
• Better control and confidence — hydraulic disc brakes and 180 mm rotors provide reliable stopping power in varied conditions.
• Simple maintenance and included tools/manual — you get what you need to keep the bike road-ready.

Features

• Multiple motor configurations: mid-drive or dual/rear motor layouts to match riding style and power needs.
• Modular three-battery system for extended range and flexibility.
• Thumb throttle for easy power control and a BC281 LCD display for ride info.
• Hydraulic disc brakes with 180 mm rotors front and rear for consistent stopping.
• 20 x 4.0" CST tires on 20" alloy rims for stability and traction.
• Optional fenders, included manual, and included tool kit.
