Pivotrax AP102F Front Tire 80/100-21

Take your ride off-road with confidence — the Pivotrax AP102F delivers reliable front-end grip and control for dirt, trail, and mixed-terrain riding.

Key Features & Benefits:
Optimized for soft to intermediate terrain: The tread compound and knob design are tuned for performance on loose dirt, sand, damp soil, and moderately rocky trails.

Excellent traction & handling balance: The tread’s void ratio offers a balance between biting grip and self-cleaning, giving you traction on loose ground without quickly clogging with mud or debris. 

Improved cornering & braking performance: The larger-contact shoulder knobs enhance stability and traction when leaning into corners or braking — giving more confidence on off-camber or uneven surfaces. 

Durable construction with terrain adaptability: A flexible yet robust carcass helps the tire adapt to changing terrain while resisting wear, making it suitable for repeated trail use. 

Ideal front wheel size: 

The 80/100-21 sizing (≈ 80 mm section width, 21″ rim diameter) pairs with common dirt-bike and electric-dirt-bike setups, providing good obstacle-rolling capability and stability on irregular terrain.

Why It Fits Your Style (Especially for Electric Dirt Bikes / Off-Road Builds):

If you run bikes similar to Sur-Ron Light Bee X or Sur-Ron Ultra Bee — or modified electric/motocross bikes with 21″ front wheels — this tire is a great match. The 21″ front diameter makes it easier to roll over rocks, roots, and rough terrain, while the tread design gives predictable control in loose or soft ground.
Good For:
•    Trail and off-road riding on dirt, sand, and mixed terrain
•    Riders who want dependable traction and good cornering stability
•    Bikes with 21″ front wheel setup (especially light electric dirtbikes or converted trail bikes)
