How To Choose the Best Bike Rack Bags:
Read on for a full list of important features to consider before choosing to buy a rack bag for your bike.
1. Waterproof Material:
When choosing any type of bike-related bag, you just have to consider the outer and inner fabric material used in that bag. Mostly we prefer waterproof polyester fabric or EVA fiber coated with PU film for best bike rack bags. This waterproof material will protect inner stored items from rain as well as from road dust.
2. Size:
The perfect size of your bag should match your needs and the size of the rear rack of your bike. Let’s suppose you carry little grocery or bakery items. Then, you can buy any regular-size rear rack bag that can hold up to 8 to 10 litres. But if you are looking for long-distance rides, then we will recommend an expendable Vantage Adventure rear rack bag with side-saddle-style panniers that can expand to give you 13-litre to 30-litre storage capacity.
3. Portable:
Always choose a portable rear rack bag that can be used as a travelling parent. Most of the above recommended bags come with adjustable shoulder straps and handle hooks to use them as a shoulder bag or to carry with hand.
4. Number of Pockets:
Think about how many small-size products you will need to carry in your bike rear rack bag. Therefore, the maximum number of inner or outer pockets will help you a lot to arrange these types of small items in a good manner. It would be better if you consider side pockets, top pockets, inner mesh pockets as well as drinking bottle pockets.
5. Free Extras:
It is your right to benefit from extra offers, especially if you are investing in getting a rear rack bag for a long time. Check the description and look for a free rain cover, adjustable top elastic cord to hold extra large items, night reflective strips or logo, crossed elastic rope, etc.
