Magic Milk Innertube BioBike Sealant - 250 ml

BioBike is focused entirely on innertubes — the result is a biodegradable formula that seals up to 6 mm in larger tyres, with no latex rubber and no palm oil.

What goes into your tyre eventually ends up somewhere else. BioBike is an innertube sealant made from vegetable and mineral ingredients — 100% biodegradable, water-based, non-corrosive. It seals punctures up to 6 mm and works with Presta and Schrader valves, from −20°C to +50°C. For tube riders who care about what they leave behind.

The plant-derived formula flows to a puncture under pressure and seals from the inside — no intervention required. It performs across the full temperature range and holds at the pressures tube riders use day to day, from 30 to 80 psi. When the tube reaches end of life, nothing toxic goes with it.

Why biodegradable

Most sealants contain synthetic compounds that don't break down. BioBike is built entirely from plant-derived and mineral ingredients — it biodegrades, and so does the chemistry inside your tube. Same puncture protection. No petrochemical residue. The choice is yours to make at the point of sale, not at the point of disposal.
