When You Should Be Concerned

Not all noises are serious, but you should pay attention if:

• The motor cuts off while riding
• The bike loses power
• You feel resistance when pedaling

 These may indicate controller or motor issues

Quick Troubleshooting Checklist

Before taking your bike for repair, try this:

• Check and tighten all bolts
• Lubricate the chain
• Test brakes and alignment
• Ride without load and listen carefully

This solves most problems in minutes.

When It Might Be Time to Upgrade

If your eBike:

• Keeps making noise after multiple fixes
• Has repeated controller or motor issues
• Feels unreliable

 It may be more cost-effective to upgrade to a more reliable model

For example:

• Rebel.2 Folding eBike – stable, quiet, commuter-friendly
• Cougar Series – durable build with strong motor performance

A well-built eBike should feel smooth, stable, and quiet under normal conditions.
