G2 Ultra vs G2 Max: Which KuKirin Wins for Light Off-Road?
Not every off-road adventure requires a 65kmh beast. Sometimes you want something lighter, more affordable, and still capable of handling gravel paths, grassy fields, and the occasional dirt trail. Enter the KuKirin G2 Ultra and KuKirin G2 Max — two capable performers from the G2 family that take very different approaches to light off-road riding.
The G2 Ultra uses dual 800W motors for all-wheel-drive traction. The G2 Max relies on a single 1000W motor but packs a larger battery for extended range. Which one is right for your weekend escapes? This head-to-head comparison breaks down every difference to help you choose.

G2 Ultra: The Hill-Climbing Specialist
The G2 Ultra is built for traction. With dual 800W motors driving both front and rear wheels, it grips loose surfaces and climbs hills with confidence that single-motor scooters can't match.
Why Choose the G2 Ultra:
1. Dual-Motor Traction (1600W Total)
The front wheel pulls while the rear wheel pushes. On gravel, grass, or wet dirt, this extra traction prevents wheel spin and keeps you moving forward. Single-motor scooters can lose grip when the rear wheel hits loose material.
2. Better Climbing Ability (26° vs 22°)
The G2 Ultra tackles steeper hills. Those extra 4° matter when you're exploring hilly trails or park paths with elevation changes. The dual motors share the load, so neither motor overheats as quickly on long climbs.
3. Larger Disc Brakes (160mm)
The G2 Ultra features 160mm disc brakes — larger than many commuter models. More stopping power means more confidence on descents.
4. Brighter Headlight (10W vs 6W)
If your off-road adventures stretch into the evening, the G2 Ultra's 10W LED (60° beam, 5m² area) illuminates the trail better than the G2 Max's 6W light.
5. Wider Touch Display (294×42mm)
The G2 Ultra's ultra-wide LED touch display is unique in the lineup. It shows speed, battery, mileage, cruise control status, and speed modes — all with touch controls.
Where It Falls Short:
| Shortcoming | Why It Matters |
|---|---|
| Shorter range (55km vs 70km) | Fewer miles between charges |
| IPX4 waterproof (vs IP54) | No dust protection rating |
| No seat included | Must purchase separately if desired |
| Narrower tyres (32-33 psi) | Less cushion than pneumatic |
G2 Max: The Long-Range Explorer
The G2 Max takes a different approach. Instead of dual motors, it uses a powerful single 1000W motor and puts the extra weight into a larger battery. The result? More range, a comfortable seat, and a simpler drivetrain.
Why Choose the G2 Max:
1. Longer Range (70km vs 55km)
The 48V 20.8Ah battery gives you 70km of range — about 25% more than the G2 Ultra. That means longer weekend adventures without range anxiety.
2. Seat Included
The G2 Max comes with a detachable seat — perfect for longer rides when you want to sit and relax. The seat is easy to remove when you prefer standing.
3. Higher Top Speed (55km/h vs 50km/h)
On open trails or roads between off-road sections, the G2 Max's extra 5km/h helps you cover ground faster.
4. IP54 Waterproof Rating
IP54 protects against dust and splashes. The G2 Ultra's IPX4 rating only guarantees splash protection. For dusty gravel trails, the G2 Max offers better peace of mind.
5. Simpler Maintenance
One motor, one controller, fewer things to go wrong. The G2 Max's single-drive system is easier to maintain than the G2 Ultra's dual-motor setup.
Where It Falls Short:
| Shortcoming | Why It Matters |
|---|---|
| Single motor (less traction) | Can spin out on loose surfaces |
| Lower climbing ability (22° vs 26°) | Struggles on steeper hills |
| Smaller 6W headlight | Less illumination for night riding |
| Smaller display (133×76mm) | Less information at a glance |
Head-to-Head: Light Off-Road Performance
| Terrain Type | G2 Ultra | G2 Max | Winner |
|---|---|---|---|
| Gravel paths | Excellent (dual traction) | Good (single rear wheel) | G2 Ultra |
| Grass fields | Excellent | Good | G2 Ultra |
| Packed dirt trails | Excellent | Very good | G2 Ultra |
| Steep hills (20-26°) | Capable | Struggles near 22° | G2 Ultra |
| Gentle hills (15-20°) | Very good | Good | G2 Ultra |
| Flat forest roads | Good | Excellent (more range) | G2 Max |
| Mixed pavement + trails | Very good | Very good | Tie |
| Long distance (50km+) | Limited by range | Excellent | G2 Max |
The Verdict on Terrain:
-
Choose G2 Ultra if your off-road routes include steep sections, loose surfaces, or technical climbs.
-
Choose G2 Max if your adventures are longer but less steep — think forest roads, canal paths, and gentle fire roads.
Range vs Traction: The Core Trade-Off
| Priority | G2 Ultra | G2 Max |
|---|---|---|
| Maximum range | 55km | 70km |
| Hill climbing | 26° | 22° |
| Loose surface traction | Dual motors | Single motor |
| Ride comfort | Spring suspension | Spring suspension (similar) |
| Night visibility | 10W headlight | 6W headlight |
| Water & dust protection | IPX4 (splash only) | IP54 (dust + splash) |
The core decision: Do you need more range or better hill climbing? The G2 Max gives you 15km extra range. The G2 Ultra gives you 4° better climbing and dual-motor traction.
Suspension and Ride Quality
Both scooters use spring-based suspension, but there are differences.
| Feature | G2 Ultra | G2 Max |
|---|---|---|
| Front suspension | Double cantilever spring | Spring shock absorption |
| Rear suspension | Double cantilever spring | Spring shock absorption |
| Tyre type | 10" vacuum (32-33 psi) | 10" pneumatic (50 psi) |
The G2 Ultra's double cantilever spring design provides more progressive damping — softer on small bumps, firmer on big hits. The G2 Max's standard spring suspension is still comfortable but less sophisticated.
Verdict: G2 Ultra has a slight edge in suspension quality for rough terrain.
Lighting: Night Off-Road Capability
| Model | Headlight | Beam Angle | Area |
|---|---|---|---|
| G2 Ultra | 10W LED | 60° | 5m² |
| G2 Max | 6W LED | 45° | 5m² |
The G2 Ultra's 10W headlight is noticeably brighter. If your off-road rides often continue after sunset, the extra 4W makes a real difference on unlit trails. Both have turn signals and brake lights.
Verdict: G2 Ultra wins for evening or night off-road riding.

Portability and Storage
| Model | Weight | Folded Size (L×W×H) |
|---|---|---|
| G2 Ultra | 30.4 kg | 1258×650×545 mm |
| G2 Max | 31.72 kg | 1260×605×580 mm |
Both are similar in weight and folded size. The G2 Ultra is about 1.3 kg lighter and folds slightly smaller. Not a dramatic difference — both are manageable for most adults to lift into a car or carry up a few stairs.
Verdict: Tie — both are similarly portable.
Price and Value
| Model | Price Range | Value for Light Off-Road |
|---|---|---|
| G2 Ultra | Mid | ★★★★ Excellent for hills |
| G2 Max | Mid | ★★★★ Excellent for range |
Both offer strong value in their respective niches. The G2 Ultra is the better investment if your priority is climbing and traction. The G2 Max is the better investment if your priority is covering long distances on mixed terrain.
