Bags, panniers, trailers

 

Backpack

Any old backpack will do. However, there are specialised cycling backpacks that have compartments for phone, wallet and keys, and have handy features like reflective strips for riding at night.

Pros: Easy to take with you - carry a little or carry a lot

Cons: Sweaty back, and uncomfortable if too full

 

Panniers

Panniers sit on either side of your bike so you can balance the load or just take one. You will need to fit a rack either to the front or rear of your bike. 

Pros: Comfortable, large capacity

Cons: Can affect handling if heavy

 

Rain covers

Most panniers and some specialist bike backpacks come with them, but you can get ‘one-size-fits-most’ options too. They not only keep your gear dry, they  protect your bag, and their bright colours are good for visibility.

Pros: Cheap, keep your stuff dry, increase your visibility 

Cons: Harder to get to your gear

 

Trailer

Suitable for much larger cargo and not so useful for a daily commute. Also handy if you are riding to a destination (eg camping) and you can detach the trailer to go riding. 

Pros: Large capacity, doesn’t affect handling too much

Cons: Heavy, expensive, needs to be locked

 

There are a number of smaller bag options such as saddlebags and handlebar bags. These are designed for smaller items such as puncture repair kit, phone, wallet etc.
