Modes and run times
Knog's figures for each of the nine modes:
| Mode | Lumens | Run time |
|---|---|---|
| High | 7 | 3 hrs |
| Low | 1 | 15 hrs |
| Side Flash | 11 | 4 hrs |
| Full Bright | 20 | 7 hrs |
| Back To Front | 5 | 13 hrs |
| Front To Back | 8 | 6 hrs |

| Rotation | 6 | 13 hrs |
| Eco | 4 | 60 hrs |
Operation and battery
One button does everything: a long press turns the light on or off, a standard press cycles through the nine modes, and a quick press while the light is off shows the battery level across the LED array in 20% steps. It charges by USB-C; the cable isn't included.
Compatibility & fit
The integrated silicone strap stretches around the tube and latches on the hook, so no tools or separate mount are needed. Knog lists a fit of 22.2 mm to 32 mm diameter; its quick start guide says the Frog fits a handlebar, seatpost or any tubular part of the bike up to 32 mm. This is the rear light only; the front Frog is sold separately.
