Using your Focus Jam² SL 8.8 eMTB is a breeze. First, turn on the bike by pressing the power button on the Fazua LED Hub. You can use the Ring Control to select different levels of motor support according to your needs. When riding, shift gears smoothly with the Shimano Deore XT M8100 shifter. For a more comfortable ride, adjust the seatpost height as per your preference. Here are some important things to note. Always wear a helmet and appropriate safety gear when riding. Don't overcharge the battery; once it's fully charged, unplug it. Avoid riding in extremely wet or muddy conditions as it may damage the electrical components. As for maintenance, regularly clean your bike with a soft cloth and mild soap. Check the tire pressure before each ride and keep it at the recommended level. Lubricate the chain every few rides to ensure smooth shifting. Also, have your bike serviced by a professional at least once a year to keep it in top condition.
