I've caught this movie quite a few times and I always enjoy it. It's the tale of a despatch rider (played by Neil Morrisey) who buys a demonically possessed motorcycle that runs on blood instead of petrol. It's a silly idea fleshed out with great characters; a comedy vicar (played by Anthony Daniels) and fine comic copper (Michael Elphick). The films cheap, but resolutely cheerful and the overall effect is very pleasing. Particularly good apres pub viewing. I'd recommend it.
