Eunorau Flash

Flash Series Electric Bike — Powerful, Long-Range Commuting

Overview

The Flash Series offers two configurations — the Flash (mid-drive, full-suspension) and the Flash AWD / Flash Lite (hub-motor options, hardtail). Both are built on a 20" 6061 aluminum frame, accept up to three batteries for extended range, and include core accessories so you can ride soon after unboxing.

Benefits

• Go farther between charges — ride up to 220 miles with three batteries, reducing range anxiety and fewer charging stops on long trips.
• Handle rough roads and stay comfortable — the full-suspension Flash soaks up bumps while the hardtail AWD/Lite is simpler and lighter for everyday use.
• Feel confident in traffic — hydraulic disc brakes and bright lights improve stopping power and visibility.
• Simplify maintenance and setup — included manual and tools mean faster assembly and basic repairs at home.
• Customize for your needs — optional fenders and multiple battery placements let you adapt the bike for commuting or longer adventures.

Features

• Multiple motor options: mid-drive and hub-motor variants to match riding style and load needs.
• Triple-battery capability for extended range without frequent recharging.
