Rambo Bikes Krusader 3.0 All-Wheel Drive – 20Ah

This all-wheel-drive electric bike combines dual hub motors with a step-through frame for travel across muddy trails, snowy fields, loose surfaces, steep hillsides, and other challenging terrain. The lowered top tube also makes mounting and dismounting easier.

A 500W motor powers each wheel, providing up to 1000W of combined nominal power. The rider can switch between front-wheel drive, rear-wheel drive, and all-wheel drive to adjust traction and power delivery for changing terrain.

The 20Ah internal battery provides a verified range of up to 65 miles. A compatible 14Ah secondary battery can extend the total range up to 110 miles using dual-battery technology.
