Few cyclists seem to wear a helmet but with winter ice, sandstorms and strong winds, a helmet is highly recommended.
Bicycles can be rented from a number of hotels and specialist cycle shops in Beijing. BicycleKingdom is one such option.

A good lock is a necessity. Cycle parking is available for a small fee at numerous pavement bicycle parks around town and you should never be too far from a bicycle repair shop if you have a puncture or some other mechanical problem.
