  1. Going the distance! Thank you Farbike :) 4 Star Review

    Posted by on 8th Jun 2015

    I've had this bicycle for about a year. I have nearly replaced the automobile. I commute to work on this bike (about twenty miles each way) and so far the bike is holding up great.

    I've had a few flat tires, and there are a few design issues, which I've also seen in some of the other reviews: I'd like to put the seat an inch or two lower (I'm 5'7) , but if I lower it, it would block installation of the battery, making it impossible for the battery to fit.
    The frame is a bit narrow in the back, requiring a bit more muscle to get the back wheel on and off for changing a tire. The back tire went flat on my first ride. I replaced it with a heavy duty tire. (I've had a few flats since then, but that's to be expected in the course of a year considering that I ride this thing sometimes more than forty miles a day on all sorts of terrain from city streets to park trails and anywhere else that looks appealing.

    I've read about spokes breaking a lot on electric bikes, but I have not had that issue. All of my spokes are still in place, I have absolutely no issues there. I'm speculating as to the cause of broken spokes for some people: Maybe they are hitting full throttle too fast, and stopping too fast? Just guessing, I could be way off. I usually start out pedaling, and get up to speed by pedal power, then use the throttle to maintain the speed. I also slow down in anticipation of red lights, so I don't have to stop fast. I've not broken a single spoke.

    I can get most of the way to work without even pedaling if I choose. I tried it just out of curiosity. Because of all of the hills, the battery will run out a few miles short of the destination. If I pedal and use the motor at the same time, I make it the full 20 miles. Then I recharge the battery while I'm at work, and have a full charge when I'm ready to go home. It takes me an hour and a half to get to work (twenty miles, mostly up hill) and only an hour to get home.

    I realize of course that most people aren't interested in commuting twenty miles to work on a bicycle, I'm probably a bit nuts. But it's a lot of fun, and a great low impact way to keep in shape. Just remember if you're commuting on a bicycle: Obey the traffic laws, put some lights on the bike if you'll be riding in low light, and a reflector vest wouldn't hurt.

    The folding thing is really convenient too! I've put it in the trunk of a car quite a few times. Easy and fast to fold up.

    I went ahead and bought a 2nd battery while I was ordering the bike, for those times when I want to take an extra long trip. I put saddle bags on the luggage rack, and carry a spare fully charged battery on every long trip just in case :)

    Farbike customer service treated me great when I was ordering this thing. Thanks a lot guys. I recommend you on a regular basis to everyone I meet who compliments the bike.

  2. Get back out there! 5 Star Review

    Posted by on 7th Jun 2015

    I really like this bike. I ride it every day (for exercise) and it does everything it promises. Take it to any local bike shop for assembly. Recommend for anyone wanting to get back out on the trails without having to dismount at hills.

  3. This thing rocks 5 Star Review

    Posted by on 27th Apr 2015

    I have had this bike for about a year now. I am very satisfied with it .. and yes the folding is quite a convinience when putting it in my SUV. everything has held up so far.. I did have a problem with spokes breaking but the company sent me a new rear tire..WOW now that was cool...and it has been working great ever since.I commute to work now as much as possible with it. also I am about 5'8 and I don't have a problem with height being an issue with this bike like I saw in some other review.This a great bike for the money.

The X-Treme XB-310Li X-Cursion - Folding Electric Mountain Bicycle

The XB-310Li electric folding bike is now called the X-Cursion for 2015 and has an amazing set of features for the price.  This electric mountain bike features a full suspension for a comfortable ride on all terrains.  This electric bicycle both a hydraulic front fork and a shock absorbing rear end so your wheels always stay glued to the ground and provides maximum safety and comfort.

On top of the comfortable ride, the X-treme XB-310Li folds to half its original length.  It features a high strength safety hinge in the middle of the frame that allows the bike to fold in half.  The hinge is designed for strength and will never fold when the bike is in motion.  This folding ability makes the XB-310Li easy to store, and fit in the trunk of most small cars, so no need for a bike rack to bring this bike with you on the road.

X-treme XB-310Li Feature List



The X-treme XB-310Li electric folding bicycle features a light weight aluminum alloy frame, and front and rear disc brakes which makes this ebike stop on a dime. The XB-310 comes with a LiFePO4 Lithium Ion electric bike battery, which is the longest last and lightest weight electric bike battery available today. This bike also uses a Shimano Tourney 7 speed gear system for smooth and reliable gear shifts.

X-Treme XB-310li Electric Folding Mountain Bike has the same specs as the XB-300Li and XB-305Li but with the added advantage of a folding frame and a rear shock absorber.  It is a great bike at an unbeatable price.  These bikes sell out quick, and FarBike is the top dealer of X-treme Electric Bikes.  Read our customer reviews below for first hand accounts from our customers.  If you have any questions please give us a call at 305-209-4411.
