The X-Treme X-Treme Boulderado Step-Through Fat Tire Electric Bike is a Lithium Battery powered e-bike cranking out 500 Watts from the Bafang High Torque Zero Resistance Clutch Motor. This e-bike features a lightweight, compact lithium LiPo4 48 volt 17 or 10.4 Ah integrated battery pack providing a considerable amount of power greater than 24 volt or 36-volt models. 

This e-bike 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, Suntour 700C Front Hydraulic Suspension, aluminum rims with quick release axle on the front, and a waterproof quick disconnect on the rear.

Powerful. Catalina comes equipped with the King Meter 5 Speed Smart Power Assist System (SPAS) with a USB Phone Charging Port.

Better. The electronics of the X-Treme Electric Bicycle are controlled via rider input on the LCD screen attached to the handlebars.

Efficient. Smart PAS with 5 speeds will enable the bike to operate nearly twice as efficiently 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 it to possibly reach or exceed 70+ miles per charge when using low SPAS while pedal assisting on flat ground under perfect conditions with a lightweight rider. The LCD also indicates Speed, Distance, and Battery Life.

Faster. It has been tested climbing a 5-7% mountain grade continuously for 45 minutes while slowing down for hairpin turns.

Safe & Comfortable. Front & rear Tetko disk brakes along with true VELO Brand Hand Grips & oversized comfy beach cruiser seat with dual springs to soften your ride.

Stylish & Convenient. It comes with a high-quality beverage holder & a folding basket that you can hang on either the front handlebars or on either side of the rear rack.
