TrueKinetix uses a very new way of creating realistic indoor sports through robotics. One of the cool features this brings is that we are able to harvest your energy and store it for later use. That is where the battery comes in. We store the energy you create in that battery.
This battery has enough power to operate the bike or trainer (without cycling) for about an hour. This is also why the trainer or bike turns of after a certain period, to preserve the battery.
