  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.
