HybridBackpack was design so that your Backpack, Laptop Bag,
Shoulder Bag or a Small Briefcase can be attached to it. The attached
unit is then place on a bicycle rack (sold separately). It comes with straps to
keep your bags from falling off the rack.
Strengths: It allowed me to take my own backpack when I go trail riding on weekends. Then when I commute to work during the weekdays I can take my laptop/shoulder bag. Also, it can carry big items such as a case of beer. See my Channel on Youtube for my video reviews. Because of its ease of use I can decide to ride with my backpack or laptop/shoulder back on my back or put it on hybrid backpack.
The product does have a big triangle reflector at the back for safety.
Weaknesses: It only came in black. My bike is orange and I wish it came in that color. It doesn't come with a cable lock so I can lock it to my bike rack. You can purchase the lock on their website.
I would recommend this product to anyone who just wants to use it to take their existing backpacks or shoulder bag or any items. It's easy to use once it's on the bike.
For touring, it's probably not a good item because you can't put a pannier on the rack when hybrid backpack is on there. But I guess it's suppose to be an alternative to a pannier.
