X-Treme Summit 48V LiPo4 Mid-Motor Powered Mountain Electric Bike


X-Treme is proud to introduce the all new X-Treme Summit 48 Mid Motor Electric Mountain Bicycle with Extra Large 10 AH 48 Volt LiPo4 lightweight battery pack. While most all other electric bicycles have the motor in the rear wheel / hub, the Summit 48 is one of the first to introduce the motor in the center of the lower frame and as a combined part of the crank system Hence: (Mid Motor). 

This is the ULTIMATE E-BIKE EXPERIENCE, it's smooth, quite, power, fast & attractive.

The benefits of a Mid Motor system include but are not limited to Zero Resistance when pedaling with the power off, low center of gravity for better handling, greater performance & lighter weight. Most of all, when the power is off and you are powering the bike by pedaling, because there is zero resistance and no heavy rear hub motor to pedal against, your overall riding experience will be identical to that of a non-electric powered bicycle (when the power is turned off).

Smart Power Assist System (SPAS): The electronics of this X-Treme Electric Bicycle are controlled via rider input on the LCD screen attached to the handlebars. This feature can allow your Summit 48 to possibly reach or exceed 40+ miles per charge (during optimal terrain conditions) LCD also indicates Speed, Distance & Battery Life. 

The upgraded SPAS also contains a torque sensor that no other X-Treme Bicycle features which will sense the torque needed to climb a hill. When climbing, the Summit 48 will increase torque output which will result in a pleasant hill climbing experience, even if the hill is steep. 

Top speed for this bike is up to 25 MPH "on throttle only" (45+ MPH if you pedal assist on LCD level 5 with the 27 speed system), faster than any model we sell, and will go the distance of up to 32 miles using power only or up to 40+ miles per charge using the SPAS on low.  Another new feature is the Shimano Tourney 27 Speed Derailleur and Shifter system (3 Speed Shimano derailleur on the front wheel and 9 Speed Shimano derailleur on the rear wheel).

Another new feature is the convenient USB port located on your battery pack to allow you to charge your cell phone, iPod or any other smart gadgets while riding your Summit 48.
