The X-treme XB-300Li Electric Bicycle is designed for reliability and comfort at an affordable price.  The XB-300Li can go 20 mph on electric power and has a range of 20-25 miles.

The XB-300li uses a Lithium Ion LiFePO4 electric bike battery, which is the best e-bike battery available today. This e-bike runs at 24 volts and has a 300 watt rear hub motor that gives the bike extended range and comfortable acceleration up to 20mph. It even has the power to get over most hills.

This electric bicycle has a twist throttle like a motorcycle and a pedal assist system that uses the electric motor while pedaling to about double the power and range of the bike. You can also turn off the battery and ride the bike unaided just like a normal bike.

The XB-300li has features only found on much more expensive electric bikes because FarBike works with our suppliers to get you the lowest price possible. We have lifetime tech support, parts and friendly support staff to help you out as long as you own your electric bike.

  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
