I know how hard it can be to find OEM Surron parts these days and these aren't needed.
All parts below are interchangeable and work with the Surron Light Bee X and Older Light Bee model.
OEM Surron Light Bee X model (Works with non X model as well) Front brake caliper and cable. Works just needs a Front Lever assembly and a brake bleed.
OEM Surron Light Bee Non X model Front brake caliper and cable. Works just needs a Front Lever assembly and brake bleed.
