This bicycle controller is an essential part of your e-bike system, allowing you to manage and control various functions of your electric bicycle for optimal performance and safety. With the 2024 model upgrade, certain controllers come with new features and improvements, which may require us to confirm compatibility with your specific bike model.

• Invoice Requirement: In such cases, we kindly ask that you provide a copy of the invoice for your bike purchase. This helps us verify compatibility and ensure the correct controller is sent to you.
• Communication: Please ensure that the email address you provide is active and regularly monitored. If we do not receive a response within a reasonable period, we will cancel your order.
