FVRITO 16x3.0 Inner Tubes TR87 Bent Valve 2-Pack — heavy‑duty rubber, spare cores & caps

FVRITO 16x3.0 inner tubes with TR87 angled valve stems are replacement tubes designed to fit 16x3.00–3.50 tires on small electric bikes, scooters, mopeds, trikes and folding bikes, sold here as a 2‑pack with valve accessories.

If you ride compact electric vehicles, kids’ chopper bikes or folding frames, getting a reliable inner tube in the right size and valve style matters for easy repairs and steady air retention. These tubes are manufactured from heavy‑duty rubber, include bent TR87 valve stems that clear rims and forks, and ship with spare cores and caps to make roadside fixes quicker. The pack is built so one purchase covers two wheels plus extra valve parts for future use.

Will this tube fit my 16‑inch tire and rim combination?

These inner tubes are sized for 16x3.00 tires and stretch to fit 16x3.25 and 16x3.50 widths, matching rims commonly found on e‑bikes, electric scooters and small mopeds. Always check your tire sidewall and rim diameter before ordering to confirm compatibility.

• Sizes compatible: 16x3.00, 16x3.25, 16x3.50
• Rim diameter match: 12 inches rim listed for common fit — verify rim marking
• Valve type: TR87 bent valve stem for constrained rim or fork clearance

How is the TR87 angled valve stem helpful for compact wheels?

A bent TR87 valve stem positions the valve at a convenient angle so pumps and pressure gauges attach easily even when rim holes or mounting hardware block straight access. The included red aluminum caps and spare valve cores reduce the chance of getting stranded with a lost or damaged cap.

• Angled valve provides easier pump attachment in tight wheel wells
• Red aluminum caps for visibility and corrosion resistance
• Spare brass cores included for quick field replacement

What materials and accessories come with the tubes?

The tubes are molded from premium heavy‑duty rubber intended to resist punctures and hold air under normal riding loads. The package adds practical repair items so you can replace cores or swap caps without running to a shop.

• Material: durable, thick rubber for longevity
• Package contents: 2 inner tubes, 2 red caps, 2 black caps, valve core wrench, 5 brass valve cores
• Designed for both home repairs and small commercial fleets

How do I install and maintain these inner tubes?

Install the tube by partially inflating it, seating it into the tire, then mounting the tire on the rim and fully inflating to the recommended pressure. Keep spare cores and the small wrench handy; replacing a core or cap is a simple five‑minute task that prevents slow leaks.

• Tip: pre‑inflate slightly to avoid pinching during installation
• Use the included wrench to tighten or replace valve cores as needed
• Check pressure regularly and inspect for embedded debris to prolong tube life

This 2‑pack with spare cores and caps is ideal for parents, repair shops, delivery services and anyone who wants to keep two wheels fully stocked for quick roadside repairs. If your vehicle uses a 16x3.x tube and would benefit from an angled TR87 valve stem for easier pump access, this FVRITO kit is a practical, ready‑to‑use option.
