Flash Series Electric Bike — Long-range, Commuter-ready

Overview

The Flash Series includes three configurations: Flash (mid-drive, full-suspension), Flash AWD, and Flash Lite (hub-motor, hardtail). Built on a 20" 6061 aluminum frame, the bikes accept up to three batteries for extended range and arrive with essential accessories so you can ride soon after unboxing.

Benefits

• Travel farther with confidence — using up to three batteries gives you long range and fewer stops to recharge on commutes and longer trips.
• Ride more comfortably on rough roads — the full-suspension Flash smooths bumps while the hardtail AWD/Lite keeps things lighter and simpler for daily use.
• Stay safer and visible in traffic — bright lights and hydraulic disc brakes improve visibility and stopping control.
• Save time on setup and upkeep — an included manual and basic tool kit make assembly and routine maintenance easier at home.
• Adapt the bike to how you ride — multiple motor options, battery placements, and optional fenders let you configure it for commuting or extended rides.
