One-piece bicycle phone holder with mechanical lock, the width can be freely adjusted within this range (6.4-8.6cm), suitable for most mobile phones on the market. The bike lighting unit has silicone pads on the bottom of the stand and on both sides of the clip to prevent scratching your phone. We've upgraded from a flexible clip to a mechanical lock to hold your phone more securely. Bike Headlights: This LED bike light set has 550 lumens of brightness and two lamp bead designs to ensure safe driving at night. In order to let you see the mobile phone navigation at a more suitable angle, we designed the lamp bead part to be adjustable up and down 45 degrees. There are 3 modes of strong light, weak light and flash, and the running time can reach 4 hours in the brightest mode. Bike stand upgrade: In order to be compatible with more bicycle handlebars, we have developed a three-section stand with an adjustable structure. The stand can be rotated 15 degrees in the horizontal plane to increase the flexibility of the light forward. The bracket is a rotary quick-release structure. Note Bike Light Set LED Battery: This lighted bike can be used as a power bank with an integrated 4000 mAh battery to charge your phone and other USB devices. There is a 4-bar power indicator next to the power bank switch button, which is convenient for you to check the remaining power and ensure timely charging. It's also IPX4 waterproof, so don't worry when it rains.
