About This Motor Axis Extender
Note: It fits BeeCool motors with an M12 x 1.25 motor bolt.
It doesn't fit our 72V Jupiter X1 series e-bikes.

1) It can be used to extend the motor axis so that you can add a pedal for the rear-seat passenger or a cargo trailer for your e-bike, because sometimes the motor axis is too short to add accessories to your bike. At this point, you need to extend the motor axis to get more gears on your bike.
2) This extender is made of aluminum.
3) The inner screw tunnel is 50mm long, and the outer screw is 20mm long.
