The City Rover Power 700 is a USB rechargeable headlight with a powerful lithium-ion battery and a darkness destroying CREE LED bulb. Equipped with a power meter on board, so you can see just how much charge you've got, the City Rover Power 700 will never leave you in the dark. Its precision reflector provides superior luminous guidance to the front and side for up to 20 hours of ride time. The City Rover will run for an additional 15 minutes in low power safety mode after the low battery indicator light comes on. Supported by the Mission Control III mounting bracket the City Rover Power 700 will never come loose or bounce about on rough terrain.
