Using your Focus Jam² 8.8 Electric Mountain Bike is a breeze. First, make sure the battery is fully charged. You can use the Bosch Kiox 300 display to control the power settings and monitor your ride stats. When riding, shift gears using the Shimano XT 1x12 shifter according to the terrain. For braking, simply squeeze the Magura MT5 brake levers. As for safety, always wear a helmet and follow local traffic rules. When it comes to maintenance, keep the bike clean after each ride, especially the chain and gears. Check the tire pressure regularly and make sure the brakes are working properly. Also, have the bike serviced by a professional at least once a year to keep it in top - notch condition.
