Frequently Asked Questions
Q1:Can the AK work with an electric tricycle control system?
Yes. It can be matched with compatible electric tricycle controllers. Electronic differential operation depends on the complete motor and controller configuration.

Q2:What water protection is available?
The matching waterproof controller version uses multiple sealing layers and has a stated immersion depth of 0.5 metres. The permitted immersion duration and conditions must follow that version’s specifications; this statement does not establish an immersion rating for the entire rear axle assembly.

Q3:Is replacement straightforward?
Positioning tools are provided to help align the assembly. The stated installation time is within two hours after removing the old assembly, provided the vehicle and mounting points are compatible.
Q3:Can it climb hills with a full load?
The stated capability is a 20° slope with an 800 kg load. The source also describes short-term operation at 1.2 tonnes, but this should not be treated as the normal load rating.

Q4:Can it be used in a modified vehicle?
Yes. Applications using an electric scooter controller may require an adapter. A matching conversion module is available.

Q5:What warranty and support are included?
The stated coverage includes a three-year frame warranty, a two-year gear-set replacement policy, and 24-hour technical support.
