If you’re in the market for a high-powered e-bike that doesn’t hold back, the EAHORA Romeo Ultra Ⅱ is one model that demands your attention. As Scott, host of BikeRide Reviews, puts it: “Today, I'm testing the EAHORA Romeo Ultra 2, the most powerful e-bike that we've ever had on the channel.” After putting this “beast” through rigorous testing, let’s break down its standout strengths—from battery capacity to suspension—followed by answers to your top questions.
Key Strengths of the EAHORA Romeo Ultra 2 (Straight from Scott’s Test)
1. Battery Capacity: A Colossal Power Reserve
This e-bike doesn’t skimp on battery size. “This bike has a 60-volt electrical system... and an 80 amp hour battery. Yes, that's a 4,800-watt-hour battery,” Scott emphasizes. He adds that the battery itself is substantial: “The 40.5-pound battery is semi-integrated into the bulky downtube structure where it's secured with a keyed block.” For context, this is far larger than the batteries of most consumer e-bikes, laying the groundwork for its impressive range and power.
2. Motor Power: 5,000 Watts of Unmatched Force
When it comes to raw power, the Romeo Ultra 2 is in a league of its own. “This monster packs 5,000 Watts of motor power. Yeah, you heard that right. Each of the wheels contains a 2,500-watt hub motor,” Scott says, noting it’s “significantly more power than anything that we've tested before.” This dual-motor setup is what gives the bike its motorcycle-like performance.
3. Controller: 41-Amp Brain for Smooth Power Delivery
The bike’s power is managed by a robust controller. “This bike has a 60-volt electrical system, 41 amp controller,” Scott explains. This component ensures the 5,000 watts of motor power is distributed effectively—whether you’re using single-motor, dual-motor, or pedal-assist mode.
4. Power & Speed: Thrills That Rival Motorcycles
The combination of big motors and a strong controller translates to blistering speed. “With both motors powering the bike, it's torky and incredibly fast. It zips past 20 miles per hour in under four seconds, and it comfortably cruises at over 40 miles per hour,” Scott raves. In formal tests, “using a single motor, the bike got from 0 to 20 miles per hour in 6 seconds... With both motors engaged, it took just four seconds.” He adds, “It really feels like an electric motorbike with some pedals attached—I found myself zooming around town on throttle power alone, easily keeping up with traffic.”

5. Range: Exceeding Expectations Even at High Speeds
Despite its power-hungry setup, the Romeo Ultra 2 delivers impressive range. “I was skeptical about EAHORA's stated battery range. However, I was pleasantly surprised as the bike managed over 70 miles with pedal assist on its highest setting,” Scott says. “On slightly lower pedal assist levels, the claimed hundred-mile range is definitely achievable.” Even in extreme conditions—“highest assist setting and dual motor mode, reaching speeds above 40 miles per hour”—it still traveled 72.75 miles, which Scott calls “the longest range that we've had from any e-bike we've tested.”
6. Hill-Climbing Ability: Dominates Steep Slopes
Hills are no match for this e-bike’s power. “This bike can climb hills at over 40 miles per hour. It is shockingly fast. I've never actually ridden an e-bike that accelerates quite so quickly up a 12-degree slope using only the throttle. It's truly exhilarating,” Scott says. In tests, “it raced up our less steep hill in just a minute and 35 seconds (50% faster than typical e-bikes) and the shorter, steeper hill in 1 minute 12 seconds—beating our previous champion, the Quiet Cat Lynx, which took 1 minute 57 seconds.”

7. Water Resistance: IPX6 for Off-Road Confidence
For riders who venture into wet or muddy terrain, the Romeo Ultra 2 has you covered. “For weatherproofing, the Romeo Ultra 2 is rated IPX6, which is a solid rating for an off-road bike,” Scott notes. This rating means it can withstand heavy splashes—ideal for off-road adventures or rainy commutes.
8. Suspension: Adjustable Front Fork & Rear Shock for Versatility
While Scott found the stock suspension firm, its adjustability is a key strength. “The hundred millimeter air fork has adjustable air pressure and compression, and the 50 millimeter air shock has rebound adjustment,” he explains. This lets riders tweak the setup to match their weight, riding style, or terrain—from smooth pavement to light gravel.
9. Maintenance & Customer Support: Accessible Channels
EAHORA’s established presence makes post-purchase care easier. “Chinese e-bike brand EAHORA has been selling bikes since 2018. They sell e-bikes direct to consumers through their website and on Amazon,” Scott shares. This direct-to-consumer model simplifies reaching support for maintenance questions or issues.
