Timbuk2 Tandem Bike Pannier
The Timbuk2 Tandem Bike Pannier are excellent on storage capacity, short length (to avoid peddle-kick), and rugged quality. Timbuk2 has two sturdy Velcro straps at top which lash to the front of the rack with no problem. It also comes with two smaller hooks on the back-side for affixing the bottom to the rack, near the tire hub. But the Velcro straps are so secure that I don't find this necessary; the bottom hooks store behind straps to prevent any interference with spokes. There is also an essential shoulder strap tucked into the pocket; no need to scavenge one-off another bag. This design, with a flat middle extension between bags that covers the rack, will allow you to pack additional stuff on top of the rack, as needed. You can just lash that extra cargo with bungee cords. You will love the simplicity of the Timbuk2 Tandem Bike Pannier, just two bags. The bag has safety reflectors on both ends. The magnets do indeed create a slim profile for the commuter load (clothes, lunch, and purse) that you carry. Great design!
