Speed Up Bag carries cyclists' stuff and reduces drag
The base version of the bag has a waterproof plastic body, a capacity of four liters, and a zippered opening in the back, facing the rider. There's no word on weight. Plans call for it to be available in a variety of colors, plus a lighter, pricier carbon fiber version is also being offered.

According to Petkovsek and his business partners, the drag coefficient of the Speed Up Bag is 60 percent lower than that of a standard handlebar bag. Additionally, use of one of the bags is said to lower the rider's own drag by approximately 15 percent, as it channels air away from the concave wind-catching surface of their chest and abdomen. This reportedly results in an average cycling speed increase of 6 percent, or 10 percent more range in the case of an electric bike.Joze is currently raising production funds for the Speed Up Bag, on Indiegogo. A pledge of US$269 will get you one, when and if they're ready to go – if you want a carbon fiber model, you'll have to offer up $399.

Iridium Go! hotspot can turn your smartphone into a satellite phone

The Iridium Go! is a lot like a portable hotspot device that you might pick up at your local wireless store. Only instead of picking up a local 4G signal to send to your tablet or laptop, it supplies some of those devices with the same data that you'd get from a satellite phone. The downside is that this data is going to be ridiculously slow (Iridium tells me "up to 2.4 kbps"). But the upside is that you'll have a connection to the outside world no matter where you are.

The Go is a fairly small and portable device, measuring 114 x 83 x 32 mm (4.5 x 3.25 x 1.25 in) and weighing 295 g (10.4 oz). When you need to send for help, check for typhoon warnings, or just check in with a loved one, you merely flip up the device's antenna. This powers on the Go and activates its hotspot.
