The X-Treme Rubicon 48V long range high power e-bike is a vast improvement on the previous Rubicon model!  Now featuring more advanced features and an all powerful 500W 48V motor, the Rubicon packs a punch without hurting your wallet!

The Rubicon cranks out 500 Watts from the Bafang High Torque Zero Resistance Clutch Motor. This e-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.  

The Rubicon 48V comes with everything Aluminum - every bolt, every nut, every nipple, every spoke.  This means no rust on any of your components!  

The 100% hand welded lightweight aluminum frame electric bicycle 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 X-Treme Rubicon comes equipped with the King Meter 5 Speed Smart Power Assist System (SPAS) with a USB Phone Charging Port.  The electronics on this e-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 electric bike, because you select the power consumption (speed controls 1-5 setting) on the LCD during your ride.  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 while having to slow down for hair pin turns. 

Front and rear Tetko disk brakes are standard on the Rubicon 48 along with true VELO Brand Hand Grips and a mountain bike seat. 

This electric mountain bicycle comes standard with a free beverage holder.  

Available in All Black or Black with Red/White Accents.

Great Bike!

My first E-bike and I am pleasantly surprised with the power of the motor. The frame is well built and the bike has quality accessories including the brakes, gears, front forks, etc. The bike's description is very accurate and delivers all claims.

Thanks for your great review Eric, and congrats on your first e-bike! We hope you enjoy riding the X-Treme Rubicon for many years to come :)

I love the bike

Nicely designed and built

Should have ordered before the price went up by $150.
Arrived in good condition except missing one bolt for mounting the front brake to the frame. How can I get this item?
