A loose or dirty battery connection is one of the most common reasons for sudden power loss.

What to do:

1. Remove the battery and inspect the terminals
2. Look for signs of corrosion or loose fit
3. Clean contacts with a dry cloth and reattach firmly

Tip: A slightly dislodged battery can cause your eBike to cut out even on smooth roads.

Even if your display shows a full battery, it could be failing internally. Lithium-ion batteries can degrade over time and lose their ability to deliver consistent power.

What to do:

1. Charge the battery fully and test again
2. If it drains rapidly, consider a battery health check or replacement

Search tip: People often google “ebike battery charged but not working”—this section covers exactly that.

Loose wiring or worn motor cables can interrupt the power supply from battery to motor.

What to do:

• Look for visible cable damage, fraying, or loose plugs
• Gently wiggle wires near the motor to test connection

If your eBike motor cuts out randomly, this is a likely culprit.

If your eBike uses a torque sensor (like Vtuvia's SN100), a misaligned or faulty sensor could be sending wrong signals.

What to do:

1. Check for error codes on your display
2. Restart the bike and watch for warning lights
3. Consult your eBike’s manual or support team

If you're riding for a long time—especially in hot weather or rough terrain—your eBike’s battery or motor might overheat and trigger a safety cut-off.

What to do:

• Pause your ride and let the bike cool down for 10–15 minutes
• Avoid keeping the throttle fully engaged for extended periods
• Store and charge the battery in shaded or cool areas when possible
