Cannondale m300 (Flagstaff)

I have a cannondale m300 mountain bike.
The bicycle is blue.
The bicycle has Shimano altus cranks 175mm long.
The bicycle is a 21 speed.
Three chainrings up front seven speeds in the rear wheel.
The brakes are smooth post cantilever.
The bike is 16 inches or 40.
6 cm.
The top tube should measure about 20 inches, but the bicycle is a low step over height style.
The rear rack, front basket, kick stand, front light, rear light, and water bottle cage are included.
I am looking to trade for a bike light kit like the Schwinn 500 and a 256 gb micro SD card.
