Using your Pedal Ranger 3 is easy. First, adjust the seat to a comfortable height so your feet can reach the pedals easily. When you're riding, use the Shimano Trigger Shifters to change gears according to the terrain. For flat roads, you can use higher gears for a faster ride. On hills, shift to lower gears to make pedaling easier. When you need to stop, gently squeeze the V - Brakes. Remember, always wear a helmet for safety. As for maintenance, regularly check the tire pressure of the 27.5' tyres. Keep the chain clean and lubricated for smooth gear changes. If you notice any issues with the front suspension fork or the drivetrain, it's best to take it to a professional bike mechanic.
