How this e-bike scores for different riding styles

High Performance
98/100

Outstanding performance with 2000W peak motor, 37 MPH top speed, 130 N.m torque, and 40° climbing capability places this among the highest-performance e-bikes available.

Off-Road Adventure
95/100

Exceptional off-road capability with 2000W peak motor, full suspension system, 26-inch fat tires, hydraulic disc brakes, and 40° climbing ability make this ideal for trails and rugged terrain.

Recreational Leisure
85/100

Full suspension, comfortable ride, cruise control, and walk mode make this excellent for leisurely rides, though it may be overpowered and heavier than needed for casual cruising.

Daily Commuting
75/100

With 50-95 mile range and 37 MPH top speed, it handles long commutes well, but the 78 lb weight and lack of folding capability make it less practical for mixed-mode transit or apartment storage.

Cargo & Utility
70/100

The 300 lb max rider weight and included rear rack support cargo hauling, but dedicated cargo bikes typically offer higher capacity and more carrying accessories.

Compact & Portable
20/100

At 78 lbs with no folding capability and large 26-inch fat tires, this bike is designed for performance rather than portability or compact storage.

Our Verdict

The FREESKY Eurostar Ultra is a powerhouse electric mountain bike that delivers amazing performance for the price. With its 2000W peak motor and huge 1200Wh battery, this bike goes fast and far - reaching 37 miles per hour and traveling up to 95 miles on a single charge. The full suspension system with lockable front fork and rear shock absorber soaks up bumps like a champ, while the fat 4-inch tires grip everything from city streets to muddy trails. At $1,249, you're getting features that usually cost much more, including professional-grade 4-piston hydraulic brakes, bright 800-lumen headlight, and smart safety lights that show when you're turning or braking.

This bike is perfect for adventure seekers who want to explore trails, climb steep hills, and ride fast on weekends. It's also great for people with longer commutes who need serious range and don't mind the weight. The 40-degree climbing ability means you can tackle almost any hill, and the cruise control feature makes long rides less tiring. The 4.8-star rating from 110 buyers shows that people really love this bike once they try it. The UL-certified battery gives you peace of mind about safety and quality.

However, this bike isn't for everyone. At 78 pounds, it's quite heavy and doesn't fold, so forget about carrying it upstairs or taking it on the subway. If you live in a small apartment or need to store your bike inside, the size might be a problem. The 5-7 hour charging time means you need to plan ahead. Also, if you want modern features like phone connectivity or USB charging for your devices, you won't find them here. People who just want a simple bike for short trips around the neighborhood might find this too much bike - it's really built for serious riding.

What We Like

  • Really powerful 2000W motor gets you up to 37 miles per hour and climbs steep 40-degree hills with ease
  • Super long battery life goes 50 to 95 miles on one charge, so you can ride all day without worrying
  • Big 4-inch fat tires and full front and rear shocks make bumpy trails feel smooth and comfortable
  • Professional 4-piston hydraulic brakes with big 180mm rotors stop you quickly and safely even at high speeds
  • Great price at $1,249 for a bike with this much power and features - costs way less than similar bikes

What Could Be Better

  • Pretty heavy at 78 pounds, making it hard to carry up stairs or lift onto a bike rack
  • Doesn't fold up, so you need plenty of storage space at home and can't take it on a bus or train easily
  • Takes 5 to 7 hours to fully charge the battery, which is longer than some other bikes
  • No phone app or USB charging port to charge your devices while riding
  • Only holds riders up to 300 pounds, which is average but not as high as some heavy-duty bikes

Standout Features

2000W Peak Motor Power
Far exceeds the 750W average, delivering nearly 3x more power for superior hill climbing and speed
1200Wh Battery Capacity (48V 25Ah)
Nearly double the typical 500-624Wh capacity, enabling the exceptional 95-mile maximum range
4-Piston Hydraulic Disc Brakes
