I. KuKirin Hears the Pain Points of Existing Users

Over the past two years, the KuKirin G2 and G4 have become the top choice for many commuters, delivery riders, and short-distance travelers thanks to their solid build quality, powerful performance, and long range.

However, precisely because of the large user base, a small design flaw has been magnified—the factory front fender is too short.

You've just washed your car, changed your shoes, and driven through a wet road left by a water truck. In just a few seconds, you have a "mud tattoo" on your chest, your right trouser leg is soaked, and even your rear footrest is covered in mud.

That's right, this is the common "pain" of KuKirin G2/G4 owners: the original scooters looked good, but they really couldn't keep out mud.

The factory design prioritizes aesthetics, with the fender flush against the tire, resulting in a clean and simple look. However, in actual riding, the water and mud kicked up by the high-speed rotation of the front wheel are not stopped by the fender; instead, they fly forward and upward along the tangent of the tire's rotation, and are then blown towards the bike and rider by the oncoming airflow.

The result was:

Mud splattered all over the chest, trouser legs, and shoes;

The rear footrest and under the seat (if it's a G4) were filthy;

Key components such as the brake calipers, front shock absorbers, and folding mechanism were chronically corroded by mud and sand, affecting their lifespan.

The good news is that in 2026, KuKirin finally received its first major upgrade—this time, they didn't blindly pile on features, but precisely addressed the most pressing pain point for owners: a complete overhaul of the front fenders, completely eliminating mud and rain splashes!

II. What's new in the 2026 front fender upgrade?

This upgrade isn't simply about "lengthening" the fenders; it involves optimization in structure, coverage area, and installation method. The key changes are summarized below:

1. Significantly increased length, wider coverage area:

The new fenders extend to the front of the front wheels. This means that mud and water splashed up when the tires spin are intercepted by the mudguard the moment they fly out, instead of being directly thrown at the rider.

2. Widened Sides for Better Protection:

The front mudguard has been widened on both sides, forming a more complete curved protective structure. Even in crosswinds or when turning at an angle, it effectively blocks lateral splashes.

3. Improved Installation Stability

The new model features a slightly adjusted mounting method, increasing the friction of the contact surface. Combined with more rationally positioned screw holes, it is more stable after installation, and the problem of abnormal noise is significantly reduced.

III. Actual Riding Experience: Really No More Mud Splashing?

Commuting Scenario Test

I wore light-colored pants and white sneakers, riding at 25-35 km/h through slippery sections. The new mudguards almost completely trapped all the water splashed up by the front wheel around the tires; only a very small amount of water mist was blown onto the shoes, but my pants, chest, and rear pedals remained mostly dry.

Rainy Day Riding Experience

In light rain, the new mudguards performed admirably. While not completely waterproof, the amount of mud and sand splashed was reduced by about 80% compared to the old model. Most importantly, there was a significant reduction in mud and sand adhering to the front shock absorbers and brake calipers, which greatly helps extend the life of the braking system and reduce abnormal noise.

Impact on Ground Clearance

Will the longer and wider mudguards affect ground clearance? In our tests, there were no problems going over curbs or speed bumps. The only thing to note is that if you frequently need to push your electric bike up relatively high steps, the front of the mudguard may make slight contact, but this will not cause damage. For most urban commuting scenarios, this length is perfectly acceptable.

IV. Installation Difficulty: ⭐ (Very Simple)

Precautions:

During installation, ensure the fender is centered with the tire; otherwise, it may rub against the tire at high speeds.

It is recommended to apply a small amount of thread-locking adhesive (blue Loctite) to the screws to prevent them from loosening due to vibration.

After installation, rotate the front wheel to check for any abnormal friction noises.

The entire installation process takes approximately 15-20 minutes and requires no technical skills; even riders with average DIY abilities can easily complete it.

Installation tools are provided with the purchase of the scooter. Attach the front fender as shown in the picture, and tighten the screws onto the front fork crossbar.

V. Is it worth the upgrade? What kind of experience will this upgrade bring you?

The experience improvement from this upgrade is very significant. For a cost of only a few tens of dollars, you get daily cleanliness and peace of mind, making it extremely cost-effective.

✅ Daily commuting, complex road conditions, frequently passing through watered areas or roads after rain;

✅ High-frequency users, riding for long periods every day;

✅ Requires a clean vehicle and doesn't want to wash the bike or shoes daily;

✅ Wants to extend the lifespan of components such as the front brake and shock absorbers.

VI. Summary: A Practical Evolution for KuKirin

In 2026, the upgrade of the KuKirin G2/G4 didn't rely on flashy technology or gimmicks, but truly addressed a real pain point that plagued countless riders from the user's perspective.

From "good-looking but not functional" to "good-looking and functional," the new front fender proves through its performance that a good electric scooter not only needs strong power and range, but also needs to withstand the test of daily use in its details.

If you're considering buying a KuKirin G2 or G4, congratulations! The 2026 model eliminates the hassle of mud.

Clean riding starts with a mudguard.
