reply from Ambifirner

Hello Christina! Thank you for your detailed feedback, and I’m truly sorry to hear about the issues you experienced with the bike. It’s unacceptable that the forks were tight without grease, the shift lever felt weak, the derailleur wouldn’t adjust properly, the rear hub was wobbly, and a bolt was missing from the rear brake. We clearly fell short of our quality standards. Please reach out to our Customer Care Team so we can look into these specific problems and assist you further. Your satisfaction is important to us, and we want to make things right.
