I bought the Kwik Tec ScootR Logic Center Bag because every girl needs more storage on her scoot. The bag is a little larger than it looks in the photos, but definitely not as large as a full-sized backpack. It's a little too big to go on the bag hook on a Honda Met. It does fit well on the front of the seat. It has a skinny nylon web strap and fastener that allows you to attach the bag around the front seat hinge so it hangs under your knees when you ride. The removable shoulder straps allow you to wear the bag as a backpack or take them off so they don't flap around while you ride. It has a large main compartment big enough for a netbook or iPad and a few other things, smaller front zippered pocket, small mesh side pocket, and a loop on the other side to attach the Kwik Tec ScootR Logic drink holder. I've had this for over a year. I highly recommend this bag.
