Controller Overheat Protection

Under some conditions, early generation CCS models sold before 2017 experienced an issue in which the motor controller (ECU) would reach a high temperature and force the system to shut down. Under load, the controller will heat up faster than it can cool itself, causing the internal temperature to rise.

As soon as you use reduce power or stop, the bike starts cooling down so that the system can operate normally again. If you shut down the bike and try to start it back up before it has adequately cooled, the bike will not start.

An overheat condition can occur under the following conditions:

1. High boost setting "S" mode is engaged while on a steep hill or pulling a heavy trailer.

2. A strong rider, cranking forcefully on the pedals will send the highest level of power through the controller while travelling on extended uphill terrain.

3. Heavy loads and low speeds where less wind is blowing over the frame.

Note:

Juiced Bikes Current-Series bikes made after 2016  have improved transistors and improved thermal management that will very rarely encounter over-heat conditions. We have also added a temperature-monitoring function in the advanced display mode of the LCD display so you can monitor the controller’s temperature while riding. When temperatures exceed 85C, the performance will be automatically reduced to avoid overheating.
