Using the Frey M600 is easy. First, make sure the battery is fully charged. Turn on the bike and select your desired assist level. When riding, use the SRAM 11 - speed drivetrain to adjust your speed according to the terrain. The Tektro HD725 Hydraulic Brakes will help you stop safely. For uphill rides, the powerful motor will give you an extra boost. When going downhill, use the dropper post to lower your center of gravity for better control. As for maintenance, keep the battery charged regularly. Check the tire pressure before each ride. Clean the bike after every use, especially after riding in muddy conditions. Make sure to service the drivetrain and brakes periodically to keep them in good working condition.
