The humble backpack can be a handy accessory for cyclists who need to carry small loads a moderate distance. 

They are very convenient, easy to access, and a well-designed pack can comfortably carry up to five kilograms. Any heavier than that and you really need to start thinking about using panniers or a rear-mounted basket. 

However, not all backpacks are the same, with those made for hiking or school usually being less than ideal for someone riding a bicycle. 

Good quality cycling backpacks are laterally stable, lightweight, waterproof and include stowaway zones or pockets for items such as helmets and water bottles.

When browsing for a new backpack, look for padding on the main supports and for extra straps across the chest and waist. 

A few people actually find that a messenger or courier bag worn across one shoulder is a more comfortable option. 

Perhaps the most important consideration in our climate is adequate ventilation – nobody likes riding around with a large patch of sweat permanently on their back.

Some of the newer cycling backpacks on the market help overcome this problem by having a small gap between your body and the pack allowing air to circulate. 

Other useful features you may like to look for include a media player/iPod cache and speaker cable outlet, reflective piping and a carry handle.
