Never stranded with a flat tyre again! Thanks to the special gel, this inner tube seals holes up to 3 mm automatically, so you can simply keep cycling.
When do you choose this product?
When do you need a 12 inch inner tube?
An inner tube for 12 inch wheels is mainly used on children's bikes, balance bikes and some compact folding bikes. This FISCHER inner tube suits several tyre widths within the 12 inch category, which makes it versatile. You need a new inner tube when the old one has a puncture that can no longer be repaired, or when the valve is damaged.
Why choose this specific size?
This inner tube fits several tyre sizes within the 12 inch category, from narrow 1.75 tyres to wider 2.25 variants. Thanks to the broad ETRTO compatibility, you don't need to know exactly which tyre size is fitted to the bike. The Dunlop valve is the standard Dutch bicycle valve, so you can simply inflate the tube with any Dutch bicycle pump.
Puncture-proof technology with gel
What makes this inner tube special is the built-in special gel that automatically seals holes up to 3 mm in diameter. This means small punctures from nails, glass shards or thorns seal themselves without you having to stop and repair straight away. The protection works continuously while you ride.
Practical fitting information
With a valve length of 35 mm, this valve fits through most 12 inch rims. Before you buy, check that your tyre matches one of the ETRTO numbers on the side of the tyre, such as 47-203 or 57-203. These numbers show the exact size and ensure the inner tube fits perfectly.
