On top of the comfortable ride, the X-treme XB-310Li folds to half its original size.  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.

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.

  1. Great bike and worth the money

    Posted by Bill on 11th Jul 2014

    I have had the 310 for a month now and it is great. It is equipped well and the folding allows me to take it anywhere.

  2. Great Entry Level Electric Bike-Fun, Efficient, Good Value

    Posted by Jim W on 10th Jul 2014

    Xtreme's XB 310 folding e-bike was a great value at the price I purchased it in April, 2014, with good components. The bike offers an amazingly smooth and speedy ride and I find the XB 310 looks much more stylish than the XB 300 & 305-it seems to be more aerodynamic than its little siblings. The bike itself is more complicated to put together than the 300 and unless you are pretty comfortable working on bikes I recommend you invest the $50-$75 and have a professional bike mechanic assemble, adjust and tune up. The bike did not come with assembly instructions but did come with a general manual and diagram. There does appear to be something of a design issue that gave me a good scare: the seat post abuts against where the battery connects, making it difficult to get a good connection. If you don't connect properly the key won't turn. I was able, after some pretty good effort, to jam the battery into the plug, but this is something the manufacturer should address. I upgraded the seat pad so I am now riding in cushy comfort. Also upgraded the headlight and added a tail light and odometer/speedometer. I really like being able to see how fast I am cruising. Unlike the XB 300, the XB 310 has its controller located high above the ground underneath the battery. The XB 310 is nice and versatile and handles excellent on road and on the trail. I am impressed. While Xtreme's XB 310 li may not have as powerful of a motor and as big a battery as my Prodeco Phantom X2 had,it offers a better overall ride than the pricey Prodeco. My Xtreme also has power-assist and a push-button mechanism for advancing gears with its Shimano shifter system--Prodeco didn't have any of this. All in all, I am extremely pleased with my Xtreme XB 310 li and highly recommend.

  3. Great Bike!

    Posted by Tony on 9th Mar 2014

    I live in Atlanta where it is very hilly. Some of the hills are so steep. I put on the pedal assist and I make it up even the steepest hill. The throttle is great for getting the bike going from a stop, it makes accelerating effortless. I've put a bunch of miles on the bike since I bought it a few weeks ago. I use it to go 3 miles to the gym and back. Even after a hard workout, the ride home is so effortless and relaxing. I had no mechanical issues with the bike and I really have nothing bad to say about it at all. If you're still deciding - get one!

  4. Very good experience to be my first e-bike

    Posted by Leonardo Monroy on 21st Jan 2014

    It was fun bicycling in this e-bike, very comfortable and easy to use, definitely it will be a useful tool to get to my work every day. thanks Farbike.

  5. very nice bike

    Posted by Thomas Laine on 20th Jan 2014

    Bike arrived very fast and in good shape except for some damage on luggage rack and the sensor at the crank was touching the wheel that activates it (not mentioned in instructions until troubleshooting section). All in all it is a very nice bike. Would not purchase if shorter that about 5'10" tall as the seat will not adjust much shorter. The damage to the luggage rack did crack the paint in a few places but I think it is still sound. I would recommend to anyone wanting a versatile electric bike.
