What are the benefits of the Halfords puncture prevention service?

Halfords’ puncture prevention service uses a high-quality Slime Bike Tyre Sealant, which is a fantastic solution for all those annoying flat tyres, whether you’re biking on the road, down the mountain or in the park, and the sealant will remain as a liquid inside your tyre, not hardening or drying out over time.

How does the puncture prevention work?

A sealant is injected into the inner tubes, and it seals a 3mm in diameter hole. If you get a puncture whilst out on a ride, all you do is pump it up and it will seal automatically.

Environmentally friendly

Environmentally friendly and non-toxic, our experts will simply fill your inner tube with the Slime Bike Tube Sealant, coating the tread area of your tyre as it rotates whilst you’re cycling.

Two-year warranty

The sealant has a two-year warranty, therefore if the product does not seal the puncture, we will replace the tube and add puncture prevention for free.



We’d always recommend adding Slime to your bike purchase and can offer this service for just £20/€24 on selected Adult Bikes, and £12/€14 on selected Kids Bikes, when you get your bike built by an expert in store.
