2026 Flight Risk SF400 EBike
$1,899.00
It is built for adventure, combining comfort, power, and control in every ride. Designed for Australian conditions, it’s refined to perform across city streets, sunburnt towns, and coastal roads with ease.
Every detail has been upgraded to enhance the ride experience. Four-piston hydraulic disc brakes deliver confident stopping power, the new supersoft seat provides lasting comfort, and precision shifters make gear changes smoother than ever. Classic MTB-style adjustable front suspension adds control over rough terrain, while the Bafang 20Ah 960Wh battery supplies consistent power to the 500W Bafang motor.
Engineered for riders who value both performance and comfort, the EBike transforms every journey into a smooth, balanced, and effortless experience.
