At Luckeep, innovation doesn’t stop at the first launch. We’ve always believed that the best eBikes are built hand-in-hand with our riders, listening to their real-world feedback and refining our products to match their needs. The M5 Ultra, one of our most popular dual motor fat tire electric bikes, has just received a major upgrade — and it’s all thanks to the valuable insights from our loyal riders.
Why We Upgraded the M5 Ultra
When the original M5 Ultra was released, it quickly became known as a high-performance, dual motor fat tire eBike with a massive riding range. Its dual-battery design allowed riders to go the distance, making it a favorite for adventure seekers, commuters, and off-road enthusiasts.
However, as more customers shared their experiences, a few recurring themes emerged:
-
Charging inconvenience: Two separate batteries meant managing two charging cycles, which wasn’t always practical.
-
Voltage drop issues: When one battery reached lower levels, riders sometimes experienced reduced performance or even unexpected cutoffs.
-
Efficiency concerns: Carrying and maintaining dual batteries added extra weight and complexity.
We took these points seriously. After months of testing in the Luckeep Product Research Lab, we are proud to announce the new single-battery M5 Ultra, now equipped with a 40Ah high-capacity battery and a 58.8V 6A fast charger.
The Advantages of the New 40Ah Single-Battery Design
The new battery system isn’t just a replacement — it’s a complete upgrade designed to improve reliability, efficiency, and user experience. Here’s what makes it special:
1. Simplified Charging
Instead of juggling two batteries, riders now enjoy the convenience of a single 40Ah battery pack. One plug, one charge cycle, and you’re ready to ride. With the new 6A fast charger, charging time is cut nearly in half compared to the previous 3A system.
2. Stronger, More Consistent Power Delivery
The new 40Ah pack reduces the risk of voltage drops at low charge levels. This means smoother performance even as the battery depletes — giving riders more confidence when pushing their limits on long trips.
3. Improved Range and Efficiency
Despite dropping the dual-battery system, the upgraded M5 Ultra still delivers up to 160 miles per charge under pedal-assist mode, thanks to its improved energy density and optimized controller system. That’s more than enough for urban commuting, mountain trails, or weekend adventures.
4. Reduced Weight and Complexity
By streamlining to a single battery, the new M5 Ultra shaves off unnecessary bulk, making it more manageable while maintaining Luckeep’s signature rugged fat tire design. Fewer components also mean fewer potential points of failure — a win for long-term durability.
What This Means for Riders
This upgrade isn’t just about specs — it’s about experience. Imagine finishing a long trail ride without worrying about balancing two charging cycles. Or commuting to work knowing your eBike delivers stable torque from start to finish. That’s what the new M5 Ultra promises: simplicity, power, and freedom.
Whether you’re a daily commuter looking for efficiency, a weekend explorer craving adventure, or a performance rider demanding torque and acceleration, the new battery and charger combination delivers exactly what you need.
Staying Ahead in the eBike Industry
The eBike market is growing fast, especially in North America, where riders are looking for high-powered, long-range electric bikes that balance convenience with durability. The upgraded M5 Ultra positions Luckeep at the forefront of this trend by solving the challenges that many dual-battery designs face.
Compared to other fat tire eBikes in its class, the M5 Ultra now offers:
-
Faster charging (6A vs. the industry average 2A–3A).
-
More stable power output across all riding conditions.
-
Class-leading 40Ah single battery, one of the largest on the market.
-
Trusted dual motor system delivering up to 3000W peak power.
A Special Thanks to Our Riders
This upgrade would not have been possible without the honest, detailed feedback from our community. One customer, Oleg, highlighted how charging two separate batteries often interrupted his daily routine. Another rider pointed out that low-voltage performance drops made off-road climbing less enjoyable.
