NIU XQi3 Wild

Overview

This fully electric dirt bike from Niu, called the XQi3 Wild, is easily the most powerful electric vehicle I've tried to date. As someone who has spent the last five years reviewing standard e-bikes, getting on a true electric motorcycle is a whole new animal, but I love it. After just a few minutes in the saddle, I knew I was hooked.

The XQi3 Wild won the Red Dot Award for design in 2024, and I think it looks absolutely fantastic in person. But it is much more than just a nice-looking bike with a lot of power. Niu actually makes two versions of this platform: a road version and this wilder off-road version. Both utilize the same 3,500 W motor, but they've done some specific tuning on the Wild to deliver that power faster and stronger. Coming in at $4,000, it bridges the gap between a high-end e-bike and a full-blown gas dirt bike, and they even give you all the paperwork needed to register it for street use.

Real-World Performance

I put the XQi3 Wild through its paces on both flat stretches and some incredibly steep, rocky trails. The bike features two primary riding modes: Eco (indicated by a green screen) and Sport (indicated by a red screen). During my speed tests on flat ground, I topped out at 37 mph in Eco mode. When I flipped the switch into Sport mode, I was able to hit 46 mph. Niu claims the bike can reach up to 51 mph, but I couldn't quite get there. Apparently, that top speed isn't achievable for a guy who weighs 180 lb like I do.

There is also a trigger for Ultra Boost mode, which delivers 36 percent more power from the motor. This mode only works when you are already in Sport mode. It provides a limited burst of power that lasts for about 15 seconds, tracked by a white timer bar that turns red as your joy is about to end. When I used Ultra Boost during my top-speed run, I still only hit 46 mph. However, when going slower, hitting that Ultra Boost trigger provided a massive, immediate feeling of increased torque and acceleration. Niu claims a 0 to 46.6 mph acceleration time of just 2 seconds, and while I wasn't crazy enough to go full-throttle from a dead stop in Sport mode, I can confirm this thing has plenty of power. It is genuinely hard to keep the front wheel down if you grab too much throttle.

To test its true off-road chops, I took it to a hill so steep that from the top, I couldn't even see all the way down. The surface was completely covered in loose, chunky rock. My first attempt didn't go too well as a rookie rider, and I struggled to maintain traction. But I refused to be defeated, turned around, and tried it again. The bike absolutely ripped up that steep, loose incline. It has tremendous power for climbing, and taking it off some small trail jumps proved it can easily handle getting off the ground.

Design & Build Quality

Coming from the e-bike world, the physical presence of the XQi3 Wild was a massive adjustment for me. This bike weighs 167 lb, which is roughly 100 lb more than most e-bikes I test. The second major difference is the ground clearance. Standard e-bikes sit about 7 to 8 inches off the ground, but this thing has roughly a foot and a half of clearance. Sitting up that high gave me a much higher center of gravity, which heavily affected my balance and stability initially. Thankfully, the learning curve was short; I was nervous doing 15 mph at first, but ten minutes down the road, I was comfortably pushing the speed.

The standout build feature for me is the suspension. The front fork offers both rebound and preload adjustments, while the rear shock features adjustable compression. With everything opened up, the ride is incredibly cushy. It exceeded my expectations when I was plowing over large rocks on the trail—it simply eats up the bumps. If you tighten the suspension down, it makes a night-and-day difference, firming up perfectly for high-speed stability on pavement.

I also have to mention the tires. They are incredibly knobby, to the point where I found a massive rock lodged directly in the tread. If you plan to use this primarily as a commuter, I highly suggest swapping those knobby tires out for street rubber.

Key Features

Starting the bike is a unique experience. It is NFC capable, and tapping the card makes a fun noise to let you know it's awake. It defaults to a red park mode where the throttle is dead—a great safety feature you can't disable. To ride, you have to put the kickstand up, hit the brake lever, and push the green button. You can also start it via Bluetooth using the app; as you approach, a blue light indicates standby mode, and holding the button for 3 seconds turns it on. It even locks automatically when you walk away.

Niu set this bike up to be street legal right out of the crate. It features low and high beams, turn signals, mirrors, a horn, a bright taillight that activates with the brake levers, and a license plate light. There are also bonus glowing side panel lights, though they aren't road-approved, so they ship disconnected. To plug them in, you have to pull the battery and connect two small wires.

That brings me to my biggest complaint: charging the bike. There is no easy-access charge port on the frame. You have to remove the seat, unbuckle straps, unplug the battery from the bike's controller, and then plug the charger directly into the battery. It is a frustrating extra step, especially since pulling out the nearly 40 lb battery is quite a chore. The upside is the massive 72V 32Ah battery charges fully in just 3 to 4 hours, and Niu says it provides up to 55 miles of range.

The app integration is deep. You can activate 'Wild Mode' to increase power delivery in both Eco and Sport. The bike's display connects to your phone to show incoming calls, though there is no built-in speaker, so the button on the dash just answers the call on your headset. You can also check error codes, adjust the movement sensitivity of the built-in alarm, unlock the seat, and record lap times using a dedicated button on the left handlebar.

Who It's For

I'd recommend the NIU XQi3 Wild to thrill-seekers and off-road enthusiasts who want the raw power of a dirt bike without the noise and maintenance of a gas engine. It is perfect for riders who want a highly capable trail machine that can also be registered and legally ridden on the street. If you live near rugged terrain or steep trails and want a plush, highly adjustable suspension to tackle them, this bike is an excellent fit.

Who Should Skip It

If you are looking for a lightweight, pedal-assist commuter, you should definitely skip this. At 167 lb with a high center of gravity, it is far too heavy and aggressive for casual bike-path riding. Additionally, if you don't have a secure garage setup and need to frequently carry your battery inside to charge, lugging the 40 lb pack out from under the seat every day will get old very fast.

How It Stacks Up

Because I strictly review standard electric bicycles, the XQi3 Wild completely shatters the scale of what I usually test. Compared to the typical fat-tire e-bikes in my garage, this Niu has vastly superior suspension, exponentially more climbing torque, and a true motorcycle seating position. It trades the lightweight agility and pedal-ability of an e-bike for raw, unadulterated off-road power. It requires registration to ride on the street, putting it in an entirely different legal and performance category than standard e-mobility devices.

Final Verdict

The NIU XQi3 Wild is an absolute beast that handled some incredibly steep, rock-covered hills during my testing. The suspension is fantastic, the tech features are genuinely useful, and hitting 46 mph on an electric vehicle of this size is a thrill. Despite the frustrating battery charging process and the heavy curb weight, for $4,000, it delivers an unreal riding experience. If you are ready to graduate from e-bikes and tackle serious trails, this is a phenomenal machine.
