The X-treme Summit 48 volt electric mountain bikes is currently the top of the line offering from X-treme E-bike. They are designed as true off road electric mountain bikes capable of tackling some of the most demanding mountain bike trails. But they aren’t just good off road, these bikes ride great on the street as well.
The mid drive brushless motor is the real star of this e-bike and this technology is usually only found in electric bikes twice the price of the summit. Among the many advantages of mid drive is the low and central center of gravity, which along with the center mounted battery, put most of the weight of this bike low and in the center, which greatly improves handling.
Because a mid-drive transfers power to the back wheel through the chain, it allows you to use the Shimano Altus 27 speed gear system to control the power of the motor. So if you’re going up a hill you can put it in a low gear and the motors power can pull you up that hill much easier. Then if you want to go faster, you can shift it into a high gear on a flat surface and get to a top speed well in excess of 20 miles per hour.
The X-treme Summit 48v has a range of around 40 miles per charge. This is thanks to the center mounted LiFePO4 10 amp hour Lithium Ion battery, that is removable so it can be taken inside to charge, or swapped out with a spare on longer journeys. The battery also locks to the bike with a unique set of keys.
This bike has both a thumb throttle, and a Smart Pedal Assist System or SPAS which amplifies the riders pedaling effort, and has five settings the rider can control from easy to aggressive. I found myself using the SPAS system almost exclusively on this bike just because it is so quick and responsive, I didn’t feel the need to use the thumb throttle too often.
The new LCD information panel shows speed, odometer, power usage, battery charge and allows you to control the SPAS power settings. The LCD panel is probably my favorite new addition to the X-treme line up, and makes it much easier to figure out how far you have traveled and how much charge you have left.
The summit has comfortable hand grips and side bars, that keep your hands from slipping off the grips when riding aggressively. The frame made from Temper Aluminum Alloy making this bike weigh in at a reasonable 51lbs. The front wheel is mounted on an adjustable hydraulic fork with a quick release axle. The tires are Kenda 26 inch x 1.95 inch mountain bike tires mounted on dual wall aluminum alloy power circle rims.
This bike has both front and back mechanical disc brakes that have allot of power. The rear cargo rack comes standard and has supports and tie downs for saddle bags.
This bike is comfortable for anyone from about 5’5” up to around 6’4”. When you order the bike, we ship it free to you via UPS, and assembly is easy which consists of attaching the front wheel, handle bars, pedals and rear rack and all the tools and instructions are included.
Maintenance is much the same as any other bike, and if you ever have a problem the 1 year warranty has you covered and we have all the replacement parts available if needed.
All around there isn’t another comparable bike at this price point that is as powerful and feature rich as the X-treme Summit Series.
