FlatOut QuickStrike Tire Sealant for Small Tires — 16 oz Kevlar‑Reinforced, Fast‑Sealing for Bikes & Scooters

FlatOut QuickStrike Small Tire/Bicycle Formula is a fast-acting, Kevlar-reinforced tire sealant in a 16-ounce bottle designed to prevent and repair punctures for tires under 3.5 inches wide.

This QuickStrike formula is engineered for small tires — bicycles, scooters, mopeds, mobility devices and single-wheel platforms — where rapid sealing and low weight matter. The product combines fast-flowing liquid with Kevlar fibers to close holes up to 1/4", resists drying out, and works in both tubed and tubeless setups. It’s water-washable and latex- and adhesive-free, which simplifies installation and cleanup.

How quickly does this sealant stop a leak?

QuickStrike is formulated to travel to the puncture faster than typical sealants, giving near-immediate sealing action for many punctures. While results vary by puncture size and tire pressure, the goal is rapid plug formation so you can get rolling again.

• Flows rapidly to the puncture for faster sealing.
• Seals tread-area holes up to 1/4 inch in many cases.
• Useful for sudden flats and gradual slow leaks alike.

Will this work in my tubed or tubeless small tire?

Yes — QuickStrike is compatible with both tubed and tubeless small tires. It is specifically tuned for tire widths under 3.5 inches, making it appropriate for most bicycles, e-scooters, mopeds, and mobility scooters.

• Suitable for tubeless and traditional tube setups.
• Not recommended for passenger vehicle tires or large commercial wheels.
• One-time application that is intended to last the life of the tire under normal use.

What makes the formula different from other sealants?

Three elements set QuickStrike apart: faster flow for prompt sealing, Kevlar reinforcement for durable plugs, and a water-washable, latex-free composition that avoids sticky residue. These features combine to provide strong, cleaner protection without frequent reapplications.

• Kevlar fibers create strong, flexible plugs that resist repeated flexing.
• Latex- and adhesive-free so it won’t gum up rims or valves.
• Non-flammable and non-corrosive for safer storage and use.

How do I install and maintain it safely?

Installation is straightforward: remove the valve core or access the tire per manufacturer instructions, pour the recommended amount for your tire size, re-inflate and rotate the wheel so the sealant coats the interior. Periodic inspection is advised, but the formula is designed to remain effective without drying out.

• Follow vehicle or tire maker guidance for valve access and quantities.
• Rotate or spin the wheel after filling to distribute sealant evenly.
• Check tire pressure and inspect for leaks after installation.

Who is this for? FlatOut QuickStrike Small Tire/Bicycle Formula is aimed at cyclists, commuters, and owners of small-wheeled mobility devices who want a dependable, low-mess solution to prevent and repair punctures. It’s ideal if you need a fast-sealing, low-maintenance product that won’t spoil rims with sticky residue. Do not use this formula for passenger car tires; select a product rated for larger wheels if needed.
