How you bikepack or bicycle tour is a personal preference based on style and values. However, the contents of what to pack are pretty universal. To help get more folks out on multi-day bicycle adventures, Mary Lytle (@maryroselytleart) and I created this pack list resource.
This resource includes a list of items I use for my packing adventures, big and small. Typically, I will bring everything listed for bicycle tours, including 2-3 "extras." For faster/more technical challenges that require minimalism, I pair down this list by sacrificing camp shoes, cooking kit, a few first aid items, and all "extras."
Consider
Research your route to understand what type of climate and environment it travels through. The nightly temperatures will dictate how warm a sleeping bag you need. A chance of rain or insects will tell you what type of shelter to bring. The frequency of resupplies informs you how much space you need for food and water.
Are you a glamper, minimalist, or somewhere in between? Your availability will dictate how much time you can spend on the route. If you have to cover a lot of distance in a short time, a set-up on the more minimal side will be practical. On the other hand, if you have 5-days to complete 100 miles, you may have time and the ability to carry more stuff (a fishing rod, coffee set-up, camp chair, etc.).
Bikepacking can be equipment-heavy, but most people have some basic camping supplies. Take an inventory and use what you have. If having the proper equipment is a barrier, check if your town has a local gear exchange/library or borrow gear.
How to pack your stuff
For optimal handling, store heavier items low and toward the center of your bicycle.
Leave space around your cockpit for things you want to access while riding.
Pack layers such as a rain jacket and gloves toward the outside of your bag so you can access them quickly without emptying all the contents of your bag.
Tip
Before your trip pack your bike with everything you plan to bring. Then, take your bike for a test ride; climb a hill, roll-off curbs, and check for any extra movement, loose items, weird noises, or bags/straps rubbing against your tire. Make any needed adjustments.
