The Rambo Bike has carved out a niche for itself, particularly among outdoor enthusiasts and hunters, thanks to its rugged build and off-road capabilities. Costco’s offering of the Rambo bike, complete with front/rear racks, fenders, and a waterproof pannier bag at $2000, has caught the attention of many. While the deal looks appealing on paper, and online reviews are mixed, real-world user experiences offer valuable insights, especially if you’re considering purchasing one. This review dives deep into the realities of owning a Rambo bike, drawing from firsthand experience and focusing on essential upgrades and whether it truly represents good value.
One user’s journey highlights the bike’s potential and its shortcomings straight out of the box. Initially intended for hauling gear and navigating challenging terrains, the stock Rambo bike reveals a gearing setup that’s less than ideal for everyday road riding. The low gearing, perfect for off-road grunt, becomes a hindrance on paved surfaces, causing legs to spin excessively at moderate speeds.
Addressing the Speed Issue: Sprocket Upgrades
The first and most impactful upgrade for road-oriented riders is addressing the bike’s gearing. The stock 34t front sprocket is geared for torque, not speed. Upgrading to a 46t sprocket provides a noticeable improvement, but for those primarily riding on roads or trails, even further enhancement might be necessary. A 52t front sprocket emerges as the sweet spot, transforming the bike’s road riding experience.

Performing this sprocket swap requires specific tools: a pedal tool, extra chain links, and a chain break tool to accommodate the larger gear. While it adds to the initial effort, the change in riding dynamics is significant.
Brake and Comfort Enhancements: Beyond Stock Components
Beyond speed, other areas of the Rambo bike benefit greatly from upgrades. The stock manual disc brakes, while functional, are often cited for being noisy. Adjusting them is crucial to mitigate squeaking, but for enhanced performance and reliability, upgrading to higher-quality disc brakes is a worthwhile investment.
Comfort is another key consideration. The factory seat tends to be uncomfortable for longer rides. Swapping it out for a comfort seat, ideally paired with a suspension seat post, dramatically improves ride quality, especially for those with lower back sensitivities. Similarly, an adjustable handlebar riser and swept-back cruiser handlebars allow for a more upright and relaxed riding posture, further enhancing comfort and control.

Tire Transformation: From Off-Road to On-Road Efficiency
The tires are another component where a change can yield substantial benefits. Stock tires designed for off-road use often generate considerable road noise and rolling resistance on paved surfaces. Switching to road-oriented tires, such as Origin8 Supercells, makes a world of difference. These tires reduce road noise, improve steering responsiveness, and, crucially, lower rolling resistance, which can positively impact battery life. Experimenting with tire pressure, slightly above the recommended maximum (e.g., 22 PSI instead of 20 PSI), can further optimize battery efficiency.
Battery and Controller Considerations
The Rambo bike’s battery performance is generally reliable. Real-world testing shows a range of around 30 miles on the lowest assist level, with battery life varying based on usage and terrain. While the battery itself may be adequate, the mounting system is an older style, potentially making it harder to find replacement batteries compared to newer, more common mounts. Upgrading the battery mount/carriage could be a future-proofing measure.
For riders seeking to unlock the bike’s full potential, flashing the controller with performance-oriented settings, like Luna’s power and speed profiles, can bypass factory-imposed speed limitations. This modification, however, may void warranties and should be approached with caution and awareness of local regulations.
Addressing the “Clicking Sound”
A common question regarding internal gear hub bikes like the Rambo is the presence of a clicking sound. This sound is inherent to internal gear hubs and is perfectly normal operation. It’s not a defect but a characteristic of this type of gearing system.
The $2000 Question: Value for Money?
The Costco price of $2000 for a Rambo bike package raises a critical question: Is it worth it? Considering the need for several upgrades to optimize the bike for road and trail riding, the total investment quickly escalates. At this price point, it’s prudent to explore other e-bike options specifically designed for road or rail trail riding that might offer comparable or better performance and components out of the box.
However, if you secured the Rambo bike at a lower price, as one user did for $1200, the cost of upgrades becomes more justifiable. The platform provides a solid base for customization, allowing riders to tailor the bike to their specific needs and preferences.
Final Verdict: Customization is Key
The Rambo bike, particularly the Costco bundle, presents a mixed bag. Out of the box, it’s a capable off-road machine with limitations for road riding. However, with strategic upgrades focusing on gearing, comfort, tires, and potentially controller settings, it can be transformed into a versatile and enjoyable e-bike. The key takeaway is that customization is often necessary to unlock the Rambo bike’s full potential, and the $2000 price tag warrants careful consideration of alternative e-bike options before making a purchase. If you are prepared to invest time and resources in upgrades, the Rambo bike can be a rewarding project; otherwise, exploring purpose-built road or trail e-bikes in the same price range might be a more straightforward path to riding satisfaction.
