Production Update: ODK 3.0 Controller System

The electronics have been upgraded to make the bike more robust and provide higher performance. Our goal is to make the electronics as simple as possible, cutting down on time needed to service the bike. 

Reducing the system's complexity reduces the number of failure points. We target 10 minutes replacement time for any electronic component including the battery and motor. Here are some highlights of the ODK Version 3's new electronics system. 


New Wiring System


It takes considerable effort to coordinate with all the parts suppliers to ensure that everything works properly. The 1-into-4 wiring harness has upgraded quick connect plugs. The new connectors now have a more attractive outer stainless steel lock-ring to prevent accidental disconnection and provide improved waterproofing. The cable design makes it impossible to incorrectly install a connector plug. 

The motor's wire can disconnect near the controller and also near the motor. This makes both tire changes and controller swaps much easier.

 

Controller Programming

The controller sends power to the motor when you twist the throttle. The sensorless controller has been reprogrammed for smoother acceleration. It takes into account the speed of the bike when delivering the power to the motor. There is reduced chance to slip the front wheel on a slippery surface even when giving full throttle. The delay in the throttle experienced on the V2 bikes after a brake cut event has been reduced.   

The controller now uses 12 Transistors instead of the 9 used in the previous version. The reliability of the controller system is improved. 

 

Upgraded Throttle

The new half twist throttle from Zannx has a more progressive throttle response. There is less on/off-ness than the previous Wuxing throttle. Also the throttle needs to be twisted less before the motor starts turning. Additionally, the larger grip feels nicer in your hand. Low speed control is smoother and easier to manage.
