- About Us
Looking for a durable, built-to-last, and feature-packed adventure bike for your next adventures? Then look no further! This bike is designed for all kinds of terrain and weather and comes with everything aluminum - every bolt, every nut, and each 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, and 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.
The Boulderado 48 Volt electric fat tire step-through mountain bicycle is a lithium battery-powered bicycle cranking out 500W from the bafang high torque zero resistance clutch motor. This bike features a lightweight, compact lithium upgraded LiPo4 48 volt 17 Ah integrated battery pack providing a considerable amount of power beyond our 10 amp battery allowing for up to an additional 75 miles range (*depending on rider weight & terrain).
The Boulderado comes equipped with the King Meter 5 Speed Smart Power Assist System (SPAS). The electronics of the X-Treme Electric Bicycle 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 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 your Boulderado 48 Volt to possibly reach or exceed 150+ 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 Electric Fat Tire Step-Through Mountain Bicycle is faster than any model we sell. It has been tested climbing a 5-7% mountain grade continuously for 45 minutes at 18 miles/hour while having to slow down for hairpin turns.

Works great. Extra space to hold more items.
Being a more affordable electric bike I wasn’t sure what to expect. I love it!! It was easy to assemble and is a great looking bike. The battery is amazing, been on four rides and my battery is at about 80%. Extremely satisfied with my purchase.
This e-bike is powerful! When they told me "hang on" .. they weren't kidding. You can feel the power from each wheel. Each wheel has its own 1000w hub motor so this bike truly defines All Wheel Drive. And the power going uphill...I weigh 245-250 lbs and this bike has no problem carrying me around anywhere. Well done Rambo!
Thank u very quick and friendly
I bought this bike to be more green. I love the way it drives. With and without batteries. I had a minor issue but their customer service is helping every step of the way. I love this cargo bike, and for the money you can’t do better. Thanks for a cool product
My e-trike is so much fun! I’ve had so many people ask me about it.
I can run so many errands with it - forget the car!
Love my bike! It was simple and easy to put together. I use the throttle to start off rather then peddling to start as it’s easier and I can control the speed better.
The EUNORAU FAT-HS Fat Tire is hefty but fun. Great for commuting and moderate single track riding. Zoom provided responsive service.
I love the bike,it rides great. I have yet to really push it but so far so good. Zoom bike has been very professional. I'm satisfied all the way around
I want to thank Zoom for a great bike , very easy to assemble. I find myself waiting for the next opportunity to venture out on my e bike. I’m a middle aged man so I can appreciate the ride this bike offers. A+
Wish I could picture but it’s all decked out and hunt ready and can carry ALOT of weight.. it’s a work of bike art and a true blessing to own!! Thanks 🙏
Great ebike for the price and so much fun riding to the beach. Great value!
Extremely satisfied with purchase of The Revi Predator.. I have put it to a moderate test as a novice rider. To streets and trails it’s smooth and seems well built to a grade heavy duty in my opinion. Shipped from Zoom warehouse in California to central indiana In within 10 days.. Package well. And Assemble within 30 minutes.. Tools required were included, Before first ride.. Insure handle bars are correctly tighten. fork nut was Lose as I made my first voyage. simply tighten. I recommend the product and Store and can validate satisfaction.
