Using your Cube women's hardtail mountain bike is easy. Just hop on and start pedaling! Whether you're on a scenic trail or racing cross - country, the bike will handle well. When you're riding, make sure to adjust the gears according to the terrain using the Shimano Tourney drivetrain. For braking, use the Tektro hydraulic disc brakes gently at first to get a feel for their responsiveness. As for maintenance, regularly check the internal cable routing for any signs of wear. Keep the threaded bottom bracket clean and lubricated. If you plan to use mudguards or a carrier, make sure they are properly attached to the mounting points. When not in use, store the bike in a dry place and use the kickstand to keep it upright. And remember, different frame sizes are designed for different riders, so choose the one that fits you best for a comfortable ride.
