Magical brick wall

The flying motorbike was equipped with a device which, when activated with a green button near the fuel guage, emitted a huge solid brick wall in the path of pursuers. The device was added to the bike by Arthur Weasley before the Battle of the Seven Potters and was used to good effect by Hagrid against Death Eaters on brooms (DH4).
