Polar Plug
Keeping your hands warm in winter is one of the endless battles in cycling. Thankfully there is a new product on Kickstarter that will make you lose those bulky gloves while biking in cold weather. Polar Plugs fit into the two ends of the handlebars, in place of the existing plugs, and with the push of a button, they will heat up to 40 Degrees Celsius (104 Degrees Fahrenheit)! The Polar Plugs are designed to fit all major manufactured bicycles, charge via USB, and are good for 5 hours on a 2-hour charge.
