The electrical drivetrain of the ZOOZ is "divorced" from the rest of the bike - which means the battery, controller, motor, and all components are stand-alone. This makes servicing the rest of the bike easy for anyone with standard bicycle knowledge.   We recommend keeping your battery in a climate-controlled environment and storing it at about half charge. Try to maintain that half charge throughout the time it is stored. Once you are ready to ride again, make sure it is fully charged up before use.   -Do not store a discharged battery. It could go into deep discharge which will reduce its life   - Even if it can withstand storage temperatures of 23°F - 104°F (-10°C - 40°C), you can optimize its shelf life by storing it at room temperature 65°-75°F (18° - 23°C).  Bicycle components will inevitably need to be replaced when they are worn out over time, due to use. It is the customer's responsibility to maintain their bike and ensure that it is in good working order before each ride. Routine maintenance and checks should be performed before each ride to ensure proper function and safety. (Damage from maintenance are not covered under warranty)  Brake pads: replace every 300 – 500 miles  Brake bleeding: preform as needed  Rotors: replace every 1000 miles (about 1609.34 km) or as needed  Chain: lubing & cleaning / replacing as needed  Tires: replace as needed  Tubes: replace as needed  As the owner of the bike, you can expect to replace or maintain all the above parts within the lifetime of your Zooz Bike.   All the parts you need to keep rolling can be found here on our website.   It is important to check your brakes periodically. IF you do need to bleed your brakes, we recommend the brake bleed kit in the amazon link below. It has everything you need and nothing you don't.
