Chinese electric bike warranty: duration and covered parts (complete guide 2026)

Warranty duration: what you really need to understand

In general, for brands such as Engwe, ADO E-Bike, Fiido, Samebike, Shengmilo, Hitway, Tenways, Lankeleisi, GUNAI, Euybike, Urlife, Hidoes, Coswheel, Akez or Randride:

- The advertised warranty is often:

• 1 to 2 years on main components

But in reality:

- each part has its own warranty period

The most important parts (and the most closely monitored)

On a comparison platform like GreenCycleHub, warranties are analysed primarily for the components that most frequently cause problems:

Battery

• Warranty: 6 months to 2 years
• This is the most sensitive component

Important:

• A gradual loss of range is normal
• Some brands limit the warranty to a certain number of charge cycles

Motor

• Warranty: 1 to 2 years
• Generally reliable

Brands like Bafang (found on certain models) often offer better reliability

Controller (the bike's brain)

• Warranty: 1 to 2 years
• Manages all the electronics

This is one of the most common causes of failure

Other components: more variable warranty

Frame

• Warranty: 2 to 5 years
• Rarely a weak point

Drivetrain (Shimano or other)

• Warranty: variable
• Often depends on the component manufacturer

Screen / display

• Warranty: 6 months to 1 year
• Sensitive to moisture and impacts

Brakes, tyres, chain

• ❌ Often considered wear parts
• Rarely or never covered

Why do warranty periods vary so much?

Because not all parts wear at the same rate:

• Battery → natural wear
• Brakes → consumables
• Motor → durable component

Brands therefore tailor their warranties according to the actual risk of failure.

How does the warranty work in practice?

Thanks to warehouses in Europe:

✔ Fast parts dispatch
✔ Online customer support
✔ No need to return the whole bike in most cases

Most of the time:

• remote diagnosis
• part replacement

Watch out for common misconceptions

❌ 2-year warranty = everything is covered for 2 years": False
