X-Treme Boulderado 500W 48V/10.4Ah/17Ah Fat Tire Step-Through Mountain eBike with 5 Levels of Pedal Assist (PAS) and Thumb ThrottleX-Treme Boulderado 500W 48V Fat Tire Step-Through Mountain eBike Happy Trails

New stock - Latest model. Limited Supply.

One of the best value 500W mountain eBike on the market.

The X-Treme Boulderado is not only a beautiful mountain eBike, but it's also loaded with features that make it the perfect electric bicycle to ride to the office every day or hit the trails.

The Boulderado 48 Volt lithium-powered electric fat tire step-through mountain bicycle is a lithium battery powered ebike cranking out 500 Watts from the Bafang high torque zero resistance clutch motor. This eBike features a lightweight, compact lithium LiPo4 48 volt 10.4 Ah/ 17Ah integrated battery pack providing a considerable amount of power greater than our 24 volt or 36 volt models.  

Features of the X-Treme Boulderado 500W 48V Fat Tire Step-Through Mountain eBike

  • Step-through frame
  • 48 Volt high power long-range
  • Integrated lithium battery
  • 500 Watt Zero Resistance rear hub motor
  • Up to 70+ miles range on a single charge (depending on rider's weight and riding conditions)
  • LCD Smart PAS digital system
  • Digital Torque Sensing
  • MOZO front hydraulic suspension - unnecessary but why not have the best?
  • Shimano Altus 9-speed
  • Tektro disc brakes
  • Kenda oversized mountain tires
  • Velo mountain bike seat - Velo grips
  • Aluminum everything - zero rust - every bolt - every nut - every nipple - every spoke

Many people associate the step-through bicycle as being for women, however, they are convenient for any gender. The big advantage of step-through bikes is that they make it easier and much more comfortable to mount the bike. Your feet will be able to touch the ground and there are no worries about losing your balance and possibly falling while trying to get on it.

This eBike comes with everything Aluminum - every bolt, every nut, every nipple, every spoke. That means no rust. The 100% hand welded lightweight aluminum frame bicycle has Atlus Shimano 9-speed gears & shifting system, oversized MOZO front hydraulic suspension, aluminum rims with quick release axle on the front, and a waterproof quick disconnect on the rear and oversized Kenda 26 x 4.0 tires. Front & rear Tektro disc brakes are standard on the Boulderado 48 Volt Fat Tire Step-Through Mountain Electric Bicycle along with true VELO brand hand grips & mountain bike seat. This electric mountain bicycle comes standard with a rear cargo rack and high-quality beverage holder. There is no extra charge.

X-Treme Boulderado 500W 48V Fat Tire Step-Through Mountain eBike Disc Brakes

The Boulderado comes equipped with the King meter 5 speed Smart Power Assist System (SPAS). The electronics of the X-Treme electric bicycles are controlled 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 eBike because you select the power consumption (speed controls 1-5 setting) on the LCD during your ride. This feature will allow your Boulderado 48 Volt to possibly reach or exceed 70+ miles per charge when using low SPAS while always pedal assisting on flat ground under perfect conditions with a lightweight rider. The LCD also indicates speed, distance, and battery life.

The Boulderado 48 Volt lithium powered Fat Tire Step-Through Mountain Electric Bicycle is faster than any model we sell. It has been tested climbing a 5-7% mountain grade continuously for 45 minutes at 18 mph while having to slow down for hairpin turns.

X-Treme Boulderado 500W 48V Fat Tire Step-Through Mountain eBike Front Suspension

Three ways to ride the X-Treme Boulderado 500W 48V Fat Tire Step-Through Mountain eBike

  • Pedal only (with no help from the motor)
  • Pedal Assist (with 5 levels of assist to choose from)
  • Throttle only (effortless like a motorcycle)

The X-Treme Boulderado can be used as a normal bike where the rider provides all the power, or you can use just the throttle and let the bike do all of the work. There is also an in-between option, Pedal Assist, where the rider pedals and the motor provides a great boost at the same time. You can choose the level that is right for your type of riding. It makes riding fun and effortless.
