Critical Operating Notes

This e-moto is not street-legal and must not be used on public roads, highways, or any street-legal surfaces. Operate only on private property or designated off-road trails with permission. Verify local regulations and obtain proper insurance before operating. Both kill switches—side stand and handlebar emergency—are critical safety devices; use both. Always wear full protective gear: helmet, gloves, protective jacket, and boots. Charge battery fully (3.5 hours) before extended riding sessions. Battery life expectancy is approximately 500 charge cycles. Dual suspension system requires periodic inspection; consult manual for maintenance intervals on inverted fork and KKE rear shock.
