Why does my FAFREES F20 Master have reduced range?
- R
  Robert MarksAug 10, 2025
  A reduced range in your FAFREES Bicycle can be caused by several factors: * **Tire Pressure:** Ensure your tires are properly inflated. * **Battery:** Check the battery connections and charge level. A low or faulty battery can significantly reduce range. * **Riding Conditions:** Excessive hills, headwinds, braking, or carrying heavy loads can impact the range. Try assisting with pedals or adjusting your route. * **Brakes:** Check if the brakes are rubbing, as this can create drag and reduce range. * **Battery Condition:** If the battery has been discharged for a long period without regular charges, is aged, or damaged, this can lead to a decline in range. If the issue persists, contact Product Support.
