What to Compare Before Buying
- Light output and runtime: Lumen output and battery runtime are not specified. Check these figures if brightness or time between charges matters to you.
- Mounting fit: The stated fit is for standard handlebars or a seat post, but no mounting dimensions are given. Check the fittings against your bike.
- Battery details: USB-C charging and a battery-level display are specified, but battery capacity and charging time are not. Look for these details if they affect your choice.
- Rating scope: Confirm whether the stated IPX5 rating applies to the front light, rear light or both.
How It Works
The front light’s sensor mode responds to ambient light as described above; manual mode lets you choose among its other listed modes. The rear light has four modes of its own, so consider which setting you want on each light.
Setup and Correct Use
The lights are described as tool-free to fit. Check that the mounting points suit your handlebar and seat post, and follow the product instructions when fitting and operating them.
A Quick Pre-Ride Lighting Check
Before setting off, check that both lights are fitted as intended, choose a front and rear mode, and check the displayed battery level. If you want the front light to respond to ambient light, make sure its sensor mode is selected.
Before You Decide
Check the mounting fit, which light the stated IPX5 rating covers, and whether the separate front and rear modes suit your needs. If runtime or brightness is important, look for those figures for the exact B9 set.
