Feeling zippy? Segway’s F40 electric kick scooter is $300 off for Prime Day and perfect for adults looking to skip the subway commute. Electric scooters are a great way to get around, but being at the whim of available Lime rentals isn’t sustainable. Owning your own scooter gives you immunity from train delays, gas price spikes, and parking fiascos. It’s also even more affordable on Amazon’s largest shopping holiday.
