2. Please note: The dual-motor version of the controller is no longer sold individually. Due to the controller upgrade, if a single controller fails, you need to replace the front and rear wheel controllers at the same time to ensure compatibility.
3.There are upgrades and replacements of the controller, and the version may be different. Please be sure to take a photo for us to confirm after purchasing. So that we will not send the wrong controller.
After March 2024, the latest version of the controller was upgraded. The details are as follows:
The new version controller does not require the motor adapter cable as shown above. The original motor adapter cable of the bicycle needs to be discarded. There is a terminal on the controller that is directly connected to the motor. This design reduces the failure points.
Payment issues
When making international payments, your issuing bank may block the transaction for security reasons. This is a protective measure.
Recommendation 1: Notify your bank in advance. Advise the buyer to call their issuing bank’s customer service before shopping, informing them that “you are about to make an overseas online transaction of [amount] in [currency],” and request authorization for this transaction.
Recommendation 2: Verify online and international payment functionality. Confirm whether your credit card has activated “online payments” and “international payments” features.
Recommendation 3: Review payment limits. Ensure your credit card’s “single transaction limit” and “daily transaction limit” are sufficient.
Recommendation 4: Try an alternative card. Occasionally, a specific card may fail authorization. Switching to another card (even from the same bank) may resolve the issue.
