Setup, Compatibility & Care
Battery Care: Charge the 345Wh battery after every ride to maintain cell health. Avoid leaving the battery in extreme temperatures (below 0C or above 40C).
Calibration: Be aware that the first 100km is a 'learning phase' for the motor system; ride naturally to allow the e-Motiq software to map your performance profile.
Maintenance: Regularly inspect the four-wheel SuperRoll+ base for debris. Keep the drivetrain clean and lubricated to ensure the 4-speed gear shifts remain crisp.
Folding Mechanism: Always ensure the frame hinges are fully locked before mounting the bike. Periodically check the tension on the fold latches to ensure a secure, rattle-free experience.
