Bee Defender Step-Thru – BeeCool’s First Super Frame eBike

The Bee Defender Step-Thru is BeeCool’s first Super Frame eBike, engineered for riders who demand range, power, and comfort.

With a 48V 20Ah lithium-ion battery, it delivers 80+ miles per charge. The 1000W brushless geared hub motor (peaking at 1300W) puts out 110Nm torque, giving you the strength to climb hills and handle rugged terrain with ease.

The brand-new Horst link full suspension system, paired with 26” x 4.8” super fat tires, ensures control, comfort, and stability across all terrains — whether commuting, exploring, or trail riding. And thanks to its low step-thru frame, mounting and dismounting is easy for riders of all heights.
