The Rambo Roamer 750 XC comes with a 48-volt 10.4 amp hour LG battery allowing you to travel up to 35 miles on one charge and a 750W high torque mid drive motor, this bike has plenty of power to get you to your destination. The Roamer features a Sturmey Archer -3 speed internal geared hub which allows this bike to operate without a traditional derailleur system. There are three ways to operate this bike, pedal assist, meaning as you pedal the motor kicks in to assist you or FULL THROTTLE or shut the motor off and just pedal like a traditional Mtn Bike. This electric bike also features 4” Kenda Krusade tires, these tires have a Kevlar anti-puncture lining to help prevent flats when riding off-road. Also, to note about these tires is Rambo’s built tough – solid double wall rim, this helps eliminates mud, water, debri and sticks from getting inside and damaging your tire, unlike most fat tire bikes out there that have the holes inside the rim. Another important feature of the Rambo Roamer is the front GT-MRK suspension fork. This allows for a much smoother ride going off-road and over bumpy terrain.
