The X-treme X-Cursion is a very cool electric bike.  It is has the power to move both on and off road and has the ability to folding in half and store easily inside or in a cars trunk.  That is the big advantage of this electric bicycle.  The stats and features are the same as the X-treme Trail Maker or X-treme Trail Climber, but this has the ability one to fold.

This X-Cusion is brand new this year, an update from the XB-310Li with new rock solid components.  The light weight aluminum frame and Lithium Ion LiFePO4 battery make is weigh only 50 lbs which is one of the lightest full size electric bikes available.  The X-cursion can do a comfortable 20 miles and hour both on and off road, and can still be ridden like a normal bike without the battery.

  1. The way to go. 5 Star Review

    Posted by on 16th May 2016

    Since getting my bike I have been stopped by all kind of people wanting to look at it and try it. My female friend went ahead and bought one for the same reasons I did, getting on in life and like me she just loves it. Doesn't ride her bike any more.
    If you want to really enjoy cycling without all the pain this is the way to go.

  2. Best thing I have ever bought 5 Star Review

    Posted by on 26th Apr 2016

    I am getting on in life and my legs were starting to burn on my regular bike. Got to the point I stopped biking. Got the 310 and I just love it. It is well built and very rugged. I have been out everyday and it is just a joy to ride.Combine the PAS and Throttle with peddling and the battery seems to go on for ever.Not been able to exhaust it yet but I am trying.If you are thinking on getting one you will not be disappointed as they are great value for the money and Farbike has the best price.

  3. 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.

  4. 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.

  5. 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.

  6. Very Satisfied 5 Star Review

    Posted by on 6th Apr 2015

    I'm very satisfied with my purchase, it makes my commute alot faster. Definitely will recommend this bike to my friends.

  7. Great bike and worth the money 5 Star Review

    Posted by 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.

  8. Great Entry Level Electric Bike-Fun, Efficient, Good Value 5 Star Review

    Posted by 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.

  9. Great Bike! 5 Star Review

    Posted by 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!

  10. Very good experience to be my first e-bike 5 Star Review

    Posted by 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.

  11. very nice bike 5 Star Review

    Posted by 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.

  12. My Favorite Bike ! 5 Star Review

    Posted by on 21st Nov 2013

    The Extreme XB 310 Li is my fave bike, even more fun than my pricy Fuji. It does not look like any electric bike, and most folks have to actually ask where battery is. Nice suspension and disc brakes and decent tires. I did have a blowout of the back tire, but some 'Fix a Flat'got me home.No problem unplugging one cable and 2 nuts to take off back wheel/motor. I have since upgraded to a heavy duty inner tube. Other add ons include mirror, gel seat cover, extra lights, grips,and horn. One thing absolutely needed is a handlebar stem riser extension (28.6 mm )and an adjustable angle threadless stem (31.8 mm ) which together raises the handlebar up a good 8 inches. Here in flat Florida I am getting over 20 mph, and even more than 30 miles between charges. I do use the handlebar mounted button to turn off the PAS peddle assist when slow riding around town or approaching intersections. The only time I use the TAG Twist and Go is for a few seconds when first starting off. All and all its a blast to ride and the price cant be beat.

  13. Good aluminum frame designed 4 Star Review

    Posted by on 12th Oct 2013

    For almost 20 years I use bike going to work and this is my first e-bike ,I received it with minor damaged and wrong part but they send me a new part and I fix it. I like the frame designed rigid and folding,Im 5'4" 155 lbs.and this size is exactly fit to me.I like also The aluminum wheels,brakes,hydraulic fork,Hub motor and gear shifter ,some parts 70% acceptable.The battery when full charge run good but after 7 or 8 miles it getting slower,I don't know how long the battery will last.I replace the inner tube when I hit a sharp metal chip. I using this 5 times a week and a total of 7 miles a day ,for me this help a lot.Thank for farbike.com

  14. Arrived when and how, exactly as advertized. Good starter e-bike. 4 Star Review

    Posted by on 14th Jul 2013

    The bike (XB310Li) arrived as promised and was easy to assemble. Instructions are not great, nor complete, but most things make obvious sense. I replaced stem, handlebars, saddle with better quality parts ($65 total), which made all the difference. I also tightened all bolts; especially pedal bolts need attention, as they settle after first use. Everything works fine so far. Paddle-assist is occasionally quirky, but handle-bar power works great (even together). Biking without power is not a good idea, as you get the motor drag.
    Always tailwind is a great sensation. Commute got a lot easier. Wrote my experience in blog: http://vdpluijm.blogspot.com/2013/06/a-hybrid-bike.html

  15. The XB310-Li just the facts 5 Star Review

    Posted by on 19th Jun 2013

    I bought this bike as an alternative to driving the 10 mile trip to work every day. So far it has served me well. I way about 225 lbs and this bike will take me 20-25 miles on a full charge. My average speed is about 18 mph on flat land. The bike can fold in half which is a huge advantage when riding the train. Its easy to fit in most of my friends cars because it can fold in half. The locking mecanism is pretty sturdy as well. Gears work great. All in all a pretty solid bike. My back tire went flat a week into riding (i did ride a lot the first week to test the durability) but this was quickly fixed at a local bike shop. Now i have a stronger inner tube in the back tire and it only cost me $30 bucks. No complaints about that. I would recommend to anyone who likes the outdoors, wants a little easy excercise to work (i never break a sweat to work and its only 12 miles from my house). Bring your charger with you as you tend to forget sometimes how much fun and how far you have actually travelled lol. Thanks FarBike.com

  16. Slick, sturdy, and functional as a commuter. (Handlebars and waterproofing should've been better designed) 4 Star Review

    Posted by on 26th Jun 2012

    *** WARNING. If you get this bike, don't use the throttle and pedal assist at the same time! You will probably burn out the controller, like I did once. And keep in mind that the pedal assist is almost always on, unless you turn it off with the key.

    I've owned this bike for a little over a year now. I am quite happy with it. For the most part, it's got quality components where it really counts (breaks, gear shift, motor, etc). The speed and range are both quite suitable, especially given that the battery recharges in about 3 hours or so (6 if you deplete it fully, which isn't recommended by the manufacturer). I have no problem riding it in either pedal assist or throttle mode to work or to a friends house, recharging it there, and riding home. If I forget the charger or something, it will get me there and back without a problem. (Max range is probably about 20 miles, maybe even a bit less if you use the throttle and have a lot of gear).

    That's another good thing about it. Gear. Cargo. The rack is quite nice, and I've added two quality paniers (search for Arkel Utility Baskets online), as well as a small tool bag, and a handlebar bag. I mean, I load this thing up! And for the most part it handles it very well. Acceleration can be a little slow, especially uphill, but I usually feel I have enough power.

    Note that the bike itself is heavy, which is both good and bad. It's good because it will protect you somewhat in case you get hit by a car, as I did not long ago. I got clipped by a car going something like 30 mph while I was going 18, and the only thing that happened was that I tipped over somewhat suddenly to one side. The weight of the bike absorbed a lot of the energy - otherwise I could've gone flying into the air.

    Finally, I'll tip my hat to the customer service people, who mostly do a very good job. They will guide you through any repairs and replacements. The warranty could be a bit longer though (parts is only 90 days, battery 12 months).

    Oh yeah, I might as well reiterate that it's slick! It doesn't even look like an electric bike unless you scrutinize it, which I sort of appreciate. I like to fit in, especially if I have to use sidewalks. Not only will you fit in as a bicyclist and not some strange-contraption-rider, you will probably get complemented.

    The downsides:

    - You will need to replace the uncomfortable seat and the cheap headlamp. Not a big deal. (Oh yeah, the tools they supply are cheap and sort of useless too.)

    - The handlebars are kind of low and far away and not adjustable. I think this is typical for a mountain bike - gives you better control or something on slopes - but it's annoying for a commuter and can cause back and neck strain. I've been meaning to get different handlebars/special grips which can fix this.

    - This thing is heavy. Good and bad, like I said. Bad because you will not enjoy yourself if the battery fails or runs down and you have to pedal it under your own power. Also, you will not want to mess with hoisting it up onto a bus rack. Or into a car trunk. Which is another thing:

    - Although it folds, it is quite big even when folded, even with the handlebars removed. Bigger than I expected. It will only fit in a very LARGE car trunk. Otherwise you'll need to leave the trunk open. Combined with the weight, this defeats the purpose somewhat, in my opinion. Not a huge thing, but good to realize this before the fact, not after the fact.

    - Not truly waterproof, though I've been lucky. I haven't had any problems personally (survived quite a few severe downpours), but I've read on forums about controllers shorting out because of rain. Having tinkered around with the controller case a bit, I'm not surprised. There are no rubber gaskets or seals around the controller - just loosely fitting plastic.

    I have a few complaints, but I'm quite happy given the price and its performance over the past year.

    *** Oh yeah, and fill the tires to 65 PSI like it says on the tires, not whatever low ball number it says in the manual (checked this with the manufacturer).
