CatEye’s AMPP 900S delivers a strong 900-lumen high beam from a compact, USB-C rechargeable body, making it a sensible all-rounder for commuting and unlit lanes. The OptiCube lens spreads light evenly across the road rather than a single hotspot, and a daytime HyperConstant mode keeps you conspicuous in traffic. The mode button glows red once charge drops below 20% so you are never caught out.
- Five modes including a 35-hour flashing setting
- USB-C charging in roughly four to eight hours
- FlexTight bracket clamps without tools
- Memory function recalls your last-used mode
