  If your ROLL-ROAD Scooter's continuous riding mileage is insufficient after charging, several factors could be at play. First, check your tire pressure and inflate if low. If the battery power is low or the charger is faulty, fully charge the battery or replace the charger. An aging or damaged battery will also reduce mileage, so consider replacing the battery. Driving on rough terrain will also reduce mileage, so adjust your route. Lastly, great headwind, frequent braking and starting, and a heavy load on the scooter can impact mileage. Adjust the bike load and consider using pedal assist.

  If your ROLL-ROAD Scooter's motor isn't working, the cell connecting line might be loose, so reconnect it. Alternatively, the speed governing throttle could be damaged; in that case, ask the distributor for a replacement. Lastly, the motor output line might be loose or damaged, so seek assistance from a repair store.

  If your ROLL-ROAD Scooter charger fails to charge, first inspect the connections to ensure they are properly connected. If the connections are fine, the fuse inside the cell box may have blown; if so, replace the fuse. Lastly, check if the battery pack's connecting wire has fallen off; if it has, weld the connecting wires back in place.
