Description: - back to top -
The X-Treme Summit 48 Volt Electric Mountain Bike is the top-of-the-line ebike from X-Treme. It’s a high-end, quality built electric bicycle from a manufacturer with 10+ years in the business. Take a good look at this one. When you factor in the quality, state-of-the-art components, boundless features and affordable price, you’ll find the Summit gives you a lot of bang for your buck.


There are tons of features that set the Summit apart from the competition, but its greatest advantage is motor placement. On most ebikes, you find the motor mounted in the hub of the rear wheel. A hub motor is heavy, impacts performance, handling and creates drag. The X-Treme Summit Electric Mountain Bike’s motor is located in the center, lower part of the frame and delivers a remarkably superior ride. In addition, the mid-motor system means you have zero resistance when riding with the power off. Riding while powered down feels almost identical to riding a standard high end bicycle.

The X-Treme Summit 48v’s 350 watt motor takes you up to 25 mph on throttle only. The Smart Power Assist System (SPAS) coupled with mid-motor placement lets you hit speeds up to 45+ mph when pedaling! The Summit delivers plenty of torque to get you up small hills and inclines on electric power alone. You can travel up to 32 miles on battery power only or 40+ miles when using the highly efficient SPAS feature. If you want to travel farther, buy another "easy swap" Summit battery pack. Carry it with you to double your ride time.

The advanced tech and features don’t end there. The X-Treme Summit electric mountain bike comes with a Shimano Tourney® 27 Speed Derailleur and Shifter system (3 speed derailleur in the front and a 9 speed derailleur in the rear). In fact, it’s the only 27 speed electric bike on the market. The front fork suspension is from Suntour®, the bicycle industries leading source. You also get JAK® 3S front and rear disk brakes, handlebar black bar ends that allow a second hand position (this increases comfort and is ideal when stand-up riding to tackle a hill or increase speed), advanced "easy swap" lithium LiFePo4 batteries, Kenda® off-road tires, a LED headlight, fully adjustable seat, a rear carry rack and more.

The X-Treme Summit 48 volt electric mountain bike comes with a Smart Power Assist System (SPAS). SPAS manages power output from the motor while pedaling to maximize efficiency. Five different power levels are available. The higher the level the more power the motor delivers. This feature makes pedaling much easier and helps take the sweat out of your ride. The SPAS on the Summit 48v is more advanced than the one found on their 36v electric bikes. The LCD display not only gives you the power assist level, battery level, speed, temperature, watt usage, an odometer and a timer, but also includes a torque sensor. This sensor detects the torque needed to climb a hill and increases torque output accordingly. The end result is a much more pleasant hill climbing experience.

Three SPAS power options are available:

1) Pedal Power Only.
2) Twist And Go (TAG) – The motor kicks in when you twist the throttle. The more you twist the faster you go. You can pedal while giving it throttle as well.
3) Smart Power Assist System (SPAS) – When SPAS is turned on, power is delivered from the motor with every rotation of the pedals. This power assist system is smart because the rider chooses the power output. SPAS offers five levels of assist from level 1 (minimum power) to level 5 (maximum power). If you need an extra boost of speed, you can always twist the throttle.
