Hongge's 20-inch mermaid bike brings a playful under-the-sea look to everyday rides, with flowing streamers and a woven front basket that add a cheerful finishing touch. A hand brake, rear coaster brake, and fully enclosed chain guard help support confident stops, while adjustable seat and handlebar heights let the bike keep pace as riders grow. Large pneumatic tires, a bell, kickstand, and front and rear reflectors round out a ride that feels practical, visible, and fun.
