Sometimes we need a little help. The Smart Wheel by FlyKly converts your regular bike into an electric bike. Just replace your rear wheel with the Smart Wheel, and you’ll get a boost of up to 25 km/h. On a fully charged battery (takes only 2-3 hours), expect travel of up to 40 km. It weighs only 3 kg, comes in 3 wheel sizes: 28”, 26”, 20” rim and 3 colors: white, silver, and glow in the dark. There’s also an app for your smart phone that allows you to lock the wheel for security, set your top speed, monitor your speed, and track other stats that you can share. Available to ship in October 2014.
