One of the fastest step-through electric mountain bicycles we carry! The X-Treme Boulderado cranks out an impressive 500 Watts of power courtesy of the Bafang high torque zero resistance clutch motor. Along with the 48 Volt 10.4ah integrated battery pack this eBike provides an enormous amount of power even greater than our 24 or 36 volt models. 

The Boulderado is made of 100% hand welded lightweight aluminum so pumping up hill is easier with all of that power at your disposal. The Smart Power Assist System (SPAS) is easily operated via the LCD screen on the handlebars. There are 5 speeds and you select the power on the setting from 1-5. The LCD also indicates speed, distance and battery life.

Under perfect conditions with a light weight rider on flat ground it can be possible to reach or exceed 70 + miles per charge when using the low PSAS.  

Oversized Kenda 26 x 4.0 tires are coupled with front & rear Tektro disc brakes so stopping on a dime is not a problem. These tires coupled with the oversized MOZO front hydraulic suspension makes riding rough terrain and doing downhill a breeze. 

You can upgrade to the 17ah Battery model and increase your range to up to 150 Miles. 

If speed and power are your thing then the Boulderado is for you.

Testimonials

I love exploring and my e-bike allows me to get out so much farther for longer without expending more energy. Thanks Crankworks for the cool mtb e-bike.

Alex M.

I find myself getting out more often with Sam and we both get great exercise. I love the fact that I can pack his and my stuff on my rack!

Heather W.

Our group rides have definitely changed since I got my QuietKat Warrior. It's become much easier as an "older dude" to keep up with the youngsters out in the woods! Loving my e-mtb!

Jay F.

I love doing a 12 mile bike loop around our lake every weekend, but it was starting to be a bit much for my knees & back to handle. The electric assist on my e-bike has been a god send! Thank you so much for making my favorite weekly activity possible & enjoyable again!!

Sally M.
