evo.com | Lezyne Front Lights > The Lezyne Mega Drive 1800i Front Bike Light does everything but pedal your bike for you. As far as lights go, this one's pretty unbelievable-evidence that it's not just bike frame materials and electronic bits that are in constant evolution. The Mega Drive 1800i can sense and adjust to ambient light, is controllable via Lezyne's free app, and is built from CNC'd aluminum to last forever. Internal USB-Rechargeable Battery Smart Connect Using the free Lezyne LED Ally phone app, Smart Connect lights can be controlled and programmed either as a combo or individually. The simple interface of the app can be used to control your lights on the fly, or to custom program the modes. If the front and rear are linked, the front light will now wirelessly control the rear light as you toggle through the modes, even if you are not connected with the app. Quick Recharge Time This light fully charges in 4.5 hours with a standard 2A USB charger. 3 LEDs Secure Strap Mount | Lezyne Mega Drive 1800i Front Bike Light 2021 in Black | Aluminum
