  1. Looks good & well built!

    Posted by Rob on 10th Sep 2014

    Nice bike once I installed a more comfortable seat & handlebar stem extender. It could be geared a little lower for my style. Other than that, you get what you pay for...I'm satisfied. Overall it is a very nice bike!

  2. XB-300Li is a great buy!

    Posted by Barry on 26th Aug 2014

    This is my third electric bike and I like it the best. I've had it two months and ride it everyday. I use it around my neighborhood on surface streets which are not very steep. I get good mileage and amble power assist from the battery. It appears to be well constructed. Assembly was pretty easy. Other than the seat being rather uncomfortable, I have no complaints at this time. I will let you know if it gives me trouble. FarBike customer service has been good.

  3. great price for good bike

    Posted by Markus on 12th Jul 2014

    good ped bike for the price..Shimano parts,solid frame, and lithium battery are the positives...sketchy brakes and average rims are the cons...battery will get you 18 to 30 miles depending on condition
    s/effort...I would recommend this bike for the price....I have ridden my extreme 300 over 1000 miles

  4. Use it on my daily 9mi one-way commute

    Posted by toni on 25th May 2014

    Bike is great-I've put on about 200mi in the past 3 weeks, and am still using the same tires and everything's running great! The bikes a bit heavy to get up and downstairs every day, but nothing I can't handle. I wish the handlebars were a bit higher, or adjustable. Just rode in a downpour and everything still works fine (so far-won't be making that a habit tho!). Seat isn't the best, I'd recommend buying a crotchless squishy schwinn or something more comfy, because it's hard and you can't adjust the tilt. I'm tall @5'11", and I've gotta have the seat at the highest position in order to extend my legs properly to the pedals, so it's a bit of a hike to have to hop on the seat since its not tilted. Ah well. Nothing Wal-Mart won't fix... Headlight is essentially a flashlight and not very bright, but it works if only to let oncoming traffic see you. Right grip likes to slip off, so I'll be whipping out some duct tape whenever it finally drives me over the edge. Great bike, easy to put together - it came with all the needed tools, and I put it together in about 30mins.

  5. XB-300Li Electric Mountain Bike

    Posted by Dexter on 24th May 2014

    So far so good the bike is great it helps a me a lot specially up hill. There is some detail that they should focus on it.The bike when you got a hard rough road the chain will detach from front gear because the gear plate is not in align.
