  If the assistance on your Bulls Bicycle isn't working, several factors could be at play. First, ensure your speed isn't exceeding 25 km/h, as the electronic gear assistance is only active up to this speed. Next, check the battery level and recharge if necessary. If you've been riding at high temperatures, up long inclines, or carrying a heavy load for a prolonged period, the battery might be too hot; in this case, switch off the drive system, wait a moment, and then check again. If these steps don't resolve the issue, the rechargeable battery, on-board computer, or assistance switch may have a problem, and you should contact your specialist dealer.

  If the drive system or on-board computer of your Bulls Bicycle fails to start, begin by checking if the battery is switched on and start it if it is not. If the battery level indicator LEDs do not light up, contact a specialist dealer. Try removing and reinserting the battery. Also, ensure all contacts are clean by wiping them with a soft cloth before reinserting the battery and attempting to start the drive system again.
