The set combines a thick, wear-resistant tread with a robust inner tube to improve durability and ride comfort on mixed surfaces. Read on for compatibility notes, performance features, installation tips and who should consider this kit.

How do I confirm this tire fits my wheel?

Always check the sidewall markings on your current tire — the correct designation for this product is 14x2.50 or 64-254. The number “14” refers to the tire's outer diameter and does not automatically mean it suits every 14-inch wheel; some vehicles use different rim standards. This kit is intended specifically for electric folding bikes and e-scooters that list 14x2.50 on the tire sidewall.

• Verify sidewall stamp: look for "14x2.50" or "64-254" exactly.
• Not compatible with tires marked 10x2.50 or 2.50-10 — those are different sizes.
• Intended for e-bikes and e-scooters, not standard bicycles.

What riding conditions and surfaces is this tire designed for?

The tread pattern and wider shoulder are optimized to handle varied surfaces common to urban and light off-road e-mobility. The rubber compound and tread depth give traction on gravel, wet pavement, compacted dirt and light snow, while the tube’s butyl construction helps dampen vibration.

• Thick tread for better grip on gravel and dirt paths.
• Widened shoulder reduces rolling resistance and improves stability.
• Butyl inner tube offers puncture resistance and smoother rides.

How easy is installation and maintenance?

Installation follows standard tire-and-tube replacement steps for small e-vehicle wheels; you’ll need basic tire levers and a pump rated for the tube’s valve type. Regular checks for proper inflation, tread wear and any embedded debris will extend service life and keep performance consistent.

• Comes as one outer tire and one inner tube per set — check your vehicle for front/rear needs.
• Use appropriate tire levers and a pump to avoid pinching the new tube.
• Maintain recommended pressure printed on the sidewall for best efficiency.

What are the construction and durability highlights?

The outer tire is crafted from durable rubber with a pronounced tread and reinforced shoulders to resist wear and improve mileage. The included inner tube is made of thick butyl rubber to reduce vibration, resist air loss and provide dependable shock absorption on uneven roads.

• Rubber compound designed for wear resistance and anti-skid performance.
• Thick tread and widened shoulder to lower rolling resistance and protect the rim.
• Butyl tube for longer hold and better damping of road vibrations.

Who is this for: riders of electric folding bikes and e-scooters that specify a 14x2.50 (64-254) tire size who want a durable, multi-surface replacement that balances grip, efficiency and comfort. If your current tire shows wear, punctures, or your vehicle’s sidewall reads 14x2.50, this NiuJKun set is a direct replacement option; do not purchase if your tire is labeled 10x2.50 or 2.50-10.
