If up and down buttons integrated in the handlebar of your ZBike don't behave correctly during a session, they may have some kind of electrical fault.
The symptoms are quite characteristic:
If it is the right up button that doesn't work correctly, the ZBike will increase the resistance to the maximum and won't slow down.
If the left button is faulty, the effect will be the opposite, you won't be able to increase the resistance.
If this is the case, please contact Zycle by completing the form below and we will contact you as soon as possible to provide a solution.
