What to consider before purchase

• Consider storage space availability at home or the workplace
• Evaluate your daily travel distance against the battery capacity and 5-hour charging time

Usage recommendations: Regularly check the tire pressure, inspect the mechanical disc brakes for wear, and ensure all folding hinges and quick-release mechanisms are securely locked before every ride. Store the battery at room temperature and avoid letting it completely drain for extended periods to maintain optimal battery lifespan.
