The Eahora Romeo Ultra is marketed as a long-range e-bike capable of traveling up to 200 miles on pedal assist and over 100 miles on throttle only. This claim is backed by its impressive 60V 70 amp-hour battery that delivers 4200 watt-hours of power — a massive capacity for a single-battery e-bike.

To truly test these claims, the bike was ridden on a three-state trip from Chicago to a my cabin in Michiana, MI, covering various terrains and conducting rigorous tests including:

• Hill climbs (including the notorious “Hill of Doom” with a 31% grade)
• Sand and off-road handling
• Brake performance at different speeds
• Long-distance endurance on throttle only

Real-World Performance Tests

Off-Road and Sand Handling

While the Romeo Ultra is not an aggressive off-road bike, its full suspension and powerful motor handle rough terrain and sand well. The bike cruised through wet sand at about 15-16 mph without issue, making it suitable for light off-road adventures and beach rides.

Hill Climb Challenge: The Hill of Doom

The bike tackled a steep 31% grade hill in pedal assist level 5 using throttle only. Although it struggled and slowed significantly, it managed to reach the top, showcasing the motor’s power under high demand. Battery consumption increased sharply during this test.

Brake Test Results

• At 21 mph, the bike took 29 feet to stop
• At 30 mph, stopping distance increased to 50 feet
• At 40+ mph, it required over 70 feet to come to a complete stop

Despite the long stopping distances, the brakes felt stable and controlled, but riders should allow ample room for stopping at high speeds given the bike’s weight and momentum.

Top Speed and Cruise Control

The bike reached a verified top speed of 43 mph at pedal assist 5. Cruise control worked well for maintaining constant speeds on open stretches, improving rider comfort during long rides.

Long-Distance Endurance: The Ultimate Test

The Journey Overview

The bike was ridden throttle only for most of the trip over approximately 87 miles covering mixed terrain including trails, city streets, and scenic paths from Chicago to Michigan City and beyond.

Battery Performance

• After 55 miles, the battery was still above 50% capacity, demonstrating excellent energy efficiency for such a heavy bike
• At 87 miles, the bike still had 20% battery remaining, proving the impressive range claim under demanding conditions
• The bike eventually cut out with no power around 90 miles, consistent with the manufacturer’s 100-mile throttle-only claim under ideal conditions

Pedaling Without Power

Once the battery died, the bike was still reasonably easy to pedal in gear 2 and 3, offering a fallback option for emergencies, although at a slower speed and greater effort.

Comfort and Handling

Riding Position and Seat Comfort

The seat is stylish but hard and not adjustable, leading to discomfort after 40 miles of riding. The aggressive forward-leaning position suits throttle riding rather than casual pedaling. After long rides, padded shorts are recommended.

Suspension Feel

Initially stiff out of the box, the suspension softened after about 50 miles, improving comfort over bumps and rough terrain. However, compared to higher-end air shocks, it remains basic.

Weight and Stability

The bike’s substantial weight contributes to a stable and centered feel, especially at speed. However, it reduces agility and ease of handling in tight situations.

Practical Considerations

Maintenance and Reliability

During the trip, a brake caliper bolt came loose but was easily fixed on the spot with basic tools. Regular checks of bolts and brakes are advised, especially after long rides.

Price and Warranty

The Eahora Romeo Ultra is priced at approximately $2,599 and comes with a two-year warranty, making it a solid investment for a high-capacity long-range e-bike.

Ideal Rider Profile

Recommended for riders between 5’5” and 6’9” in height, and weighing up to 300 pounds. Best suited for those prioritizing range and power over lightweight agility or comfort.

Final Thoughts: Is the Ehora Romeo Ultra Worth It?

The Eahora Romeo Ultra is a beast of an e-bike designed for riders who want to cover long distances at high speeds with throttle-only power. It excels in battery capacity, power output, and versatility across different terrains, making it ideal for adventure seekers and commuters who demand range and reliability.

However, its heavy weight, firm suspension, and hard seat mean it’s not the most comfortable bike for long rides without additional accessories or modifications. The long stopping distances at high speeds also require caution.

If you’re looking for an e-bike that can truly go the distance with minimal pedaling and deliver thrilling speeds, the Romeo Ultra is a compelling choice — just be prepared for the physical demands and size of this machine.
