You look around at E-Bikes and nothing seems to be able to do everything you need, and stay in budget right? Stop right there! Look no further, the Rubicon is here!  Insane Power!  Battery Life! Comfort! And Versatility!  One of our Best Sellers! The Rubicon Lithium Battery powered E-bike cranks out 500 watts from the Bafang High Torque Zero Resistance Clutch Motor with Digital Torque Sensor. This bike features a lightweight, compact lithium LiFePo4 48 volt 10.4 Ah integrated battery pack providing a considerable amount of power greater than our 24 volt or 36 volt models. This bike comes with everything Aluminum - every bolt, every nut, every nipple, every spoke. The 100% hand welded lightweight aluminum frame has Atlus Shimano 9-Speed Gears & Shifting System, Suntour XCT Front Suspension & KS Rear Shock Suspension, aluminum rims with quick release axle on the front and a water proof quick disconnect on the rear.

The Rubicon comes equipped with King Meter 5 Speed Smart Power Assist System (SPAS) with a USB Phone Charging Port. The electronics of the X-Treme Electric Bicycle are controller via rider input on the LCD screen attached to the handlebars.  Smart PAS with 5 speeds will enable the bike to operate nearly twice as efficient as a non-smart assist e-bike, because you select the power consumption (speed controls 1-5 setting) on the LCD during your ride.  This feature will allow your Rubicon 48 Volt to possibly reach or exceed 35-55+ miles per charge when using low SPAS while always pedal assisting on flat ground under perfect conditions with a light weight rider.  The LCD also indicates Speed, Distance and Battery Life.

The Rubicon 48 Volt Lithium Powered Electric Mountain Bicycle is faster than any model we sell.  It has been tested climbing a 5-7% mountain grade continuously for 45 minutes at variable speeds while having to slow down for hair pin turns*.

The Rubicon has variable speeds (faster if you pedal*) which is faster than any model we sell and will go the distance of up to 70 miles range using low PAS & flat terrain while pedal assisting*. The LiFePo4 lithium battery pack is lightweight, compact and mounts to the down tube of the frame and is hardly noticeable since it matches the color of your bicycle frame.

Front & rear Tetko disk brakes are standard on the Rubicon 48 Volt Electric Mountain Bike along with true VELO Brand Hand Grips & Mountain Bike Seat. 

This electric mountain bicycle comes standard with a high quality beverage holder!

*Max Speed & Mileage is not guaranteed and depends on rider weight & terrain Distance obtainable when using SPAS.

      Great bike

      I purchased this bike as a replacement to a Giant mountain bike that I had for about 10 years. I was a little worried about purchasing a bike on line as well as the whole ebike shame vibe from other riders.
      Journey bikes made the purchase a breeze.
      Everyone of my biking friends that has tried the bike has been impressed with the value of my x treme mountain bike.
      I have about 400 miles on my bike and have had zero problems. The way I use the bike I have averaged about 250 miles per charge. The top speed on level ground that I have seen is 22mph.
      Is this like riding a 5 to 6000 dollar mountain bike? No, but what bang for your buck at this price point.

      So sweet

      I put it together myself, against my better judgement, but it came out fine. It just took longer than I thought it would.
      Let me say right now this thing far exceeded my expectations. It hauls a$$.
      I'm 250 lbs and on flat ground I can go 22 mph without pedaling. But it will wear your battery out quicker.
      When I go for a longer ride, I go easy on the assist level keeping it at 1 or 2.
      I can go 30 miles on a charge. But, if I am in a hilly area punching it, I only go around 10-15 miles.
      I love this thing. I have over 320 miles in a month. It is really fun to drive and in a beach community it is perfect to run around.
      Owner was chatting online with me making the decision easy.
      Thanks Journeybikes
      I can't wait til they design a battery that will last longer.

      Great bike so far. 350 miles no issues. Thank you Xtreme and Journeybikes!

      Great choice

      I wasn't sure whether to pick the Rubicon or sedona, both had similar features, but I went with this, I love it! I have a 10 mile trip each way to work and I have plenty of juice left each day. Super fast, I really love this bike, thanks!

      Really nice design, handles comparable to my mountain bike, suprising for an ebike, once you try an ebike it is hard to go back!
