Dominate any terrain with the Rambo Megatron 4.0 All-Wheel Drive E-Bike, dubbed "The Beast of E-Bikes" for its raw power and relentless performance. Since pioneering the AWD e-bike revolution in 2019, Rambo has refined this beast over six years, culminating in the Megatron 4.0—a machine built to tackle mud, steep hills, and rugged trails with ease. Powered by dual 1000W Bafang hub motors delivering up to 2000W of nominal power and 180 Nm of torque, this e-bike offers unmatched acceleration, speed, and hill-climbing prowess.
Take control with the on-the-fly AWD system, seamlessly toggling between front-wheel drive (FWD), rear-wheel drive (RWD), or all-wheel drive (AWD) to adapt to any environment—maximizing traction on loose gravel or conserving battery on flat trails. Equipped with an integrated rear rack, full front and rear fenders, and a custom Rambo Storm LED lightbar (toggleable between white and green), the Megatron 4.0 is adventure-ready from the start. Its hydroformed aluminum alloy frame is tig-welded for rugged durability, paired with a maintenance-free single-speed gear system (upgradeable to Shimano 8-speed) for a smooth, reliable ride.
Choose a 20Ah or 30Ah battery, or add an optional 14Ah battery for up to 110 miles of range—perfect for long hunts or epic explorations. Stop on a dime with Logan 4-piston hydraulic brakes, and roll confidently on Kenda 26” x 4.8” anti-puncture tires. Whether you’re an off-road junkie, a hunter hauling gear, or an adventurer pushing limits, the Megatron 4.0 delivers power, versatility, and reliability like no other.
Why the Megatron 4.0 Stands Out-
Extreme Power: Dual 1000W motors conquer any challenge with 2000W output.  
Adaptive Traction: On-the-fly AWD for ultimate control across terrains.  
Long-Range Capability: Up to 110 miles with dual battery setup.  
Built Tough: Rugged frame and accessories for off-road mastery.
Rider Feedback: Users love its dirt bike-like power, exceptional hill-climbing ability, and AWD versatility. The integrated rack and fenders make it a hunter’s dream, though its 75 lbs frame (without battery) reflects its heavy-duty build.
Compared to Others: Outmuscling the Rambo Krusader 3.0 (dual 500W motors), the Megatron 4.0’s dual 1000W motors double the power for extreme conditions. It also outshines the Megatron 2.0 with enhanced battery options and accessories.
Motor: Bafang dual 1000W hub motors (2000W nominal, 2500W peak, 180 Nm torque)  
Battery: 48V 20Ah (960Wh) or 30Ah (optional); add 14Ah for dual battery setup  
Range: Up to 65 miles (single battery), 110 miles (dual batteries)  
Speed: Up to 36 mph  
Frame: Hydroformed aluminum alloy 6061 T6, heat-treated, tig-welded  
Tires: Kenda 26” x 4.8” anti-puncture aggressive tread

Took this beast out into the mountains last weekend and it did not disappoint. The AWD mode makes a huge difference in loose terrain, and the torque is unreal. It feels more like a lightweight dirt bike than a typical e-bike. Shipping from The Prime Pinnacle was smooth, no issues at all.
Thanks so much, Malik! We’re thrilled the Megatron is powering your adventures. Appreciate you supporting our first responder-owned small business!
This bike is a beast. It’s on the heavier side, but that’s the tradeoff for the power and durability. Took it through some muddy trails and it powered right through. Would love a bit more gearing flexibility, but overall very happy.
Appreciate your honest feedback, Dae-Hyun! Great to hear the Megatron is handling the trails well. Thanks for choosing to support a first responder-owned business!
The Megatron 4.0 is intense—in the best way. I had to get used to the AWD toggling, but once I figured it out, it was smooth riding. Very comfortable saddle and great battery life. Only wish the display was a little easier to read in bright sun.
Thank you, Anya! We’re glad the Megatron is delivering the performance you expected. Your support means a lot to our small, first responder-owned team!
This thing is an absolute powerhouse. I use it for hunting and it handles mud, inclines, and rocky trails effortlessly. The integrated light bar is brighter than expected. Ordering from The Prime Pinnacle was super easy and the support team was really responsive.
Javier, we really appreciate your support! Glad to hear your Megatron is performing out in the wild. Thanks for backing a small business built by first responders.
I've tried a few fat-tire e-bikes, and this one blows them away. Dual motors really do make a difference when climbing or going through soft sand. It’s a bit overkill for city riding, but off-road? Nothing compares.
Thank you, Fatima! We’re so glad the Megatron is living up to the hype. We truly appreciate your support!
Let customers speak for us
from 830 reviewsThe most solid Frame and design I've ever had. I love this bike..
 
  You can feel the quality the moment you swing it. The U19 gives a strong, mid high flight with a bit of draw bias. Exactly what I was hoping for. Easily my favorite hybrid now.
 
  I play the 5W in R flex and love the feel. The club sits nicely at address and the lighter swing weight (around D0) makes it super easy to control through impact.
 
  From the satin and gold finish to the soft contact feel, everything about these irons screams quality. They’re extremely forgiving, even with the lower lofts. The weight and lie angle feel dialed in perfectly for me.
 
  Turned our weekend into luxury with room for 12 beds and cots. The storm doors and mesh windows kept bugs out while letting in breeze. Easy to maintain with the PVC groundsheet.
 
  Took these out for my first round last weekend, absoilutely unreal. The sound off the face is pure, and the distance is consistent even on off center hits. You can feel the craftsmanship in every club.
 
  This tent is massive—384 sq. ft. fits our whole family plus gear comfortably. The stove jack kept us toasty in fall, and setup was straightforward with the included frame. Highly recommend for group outings!
 
  The ball flight is nice and high without ballooning. I’m using the R flex version and it’s very stable. Even with my moderate swing speed, I’m getting great carry and predictable spin from the 9 and PW
 
  fit our hunting group's gear and cots for 12 w/ room to spare. The canvas held up in heavy rain, and the stove jacks kept us warm. Setup was a team effort but worth it!
 
  You can tell this was handcrafted. The balance and feedback are outstanding. Every shot feels controlled and solid.
 
  This machine cranks up the challenge with 80mph speeds and heavy backspin, helped me nail my returns in no time. Electronice elevation for lobs is spot on for overhead practice. The Prime Pinnacle's tracking updates were flawless!
 
  Perfect for our tennis acadmey! Players the different drill variety. The hopper is large enough to have continous sessions without reloading. Kept us updated every step of the way with tracking. Worth every penny for serious training!
 
  Takes my practice to the next level! Feels just like a real match. Battery lasts through long sessions. Prime pinnacle has great customer service!
 
  The upgraded battery gives 7+ hours of play, ideal for advanced volleys and spins without interruptions. It's a bit heavier than the original, but the features make up for it. The 100 pack of pickleballs is a great deal as well and they feel great!
 
  This fireplace is a stunner in my living room! The flame styles and crackling sounds create such a cozy vibe. App control is seamless. Prime Pinnacle support was great and tracking updates were perfect. Arrived quickly and in great shape
