Using your Tech Deck BMX Finger Bike is super easy. Just hold the bike firmly between your fingers and use the articulated handlebars to control it. You can pull off cool tricks like tail whips and flips by moving your fingers in a quick, coordinated way. When using it on the ramp sets, make sure to place the bike on the ramp carefully to start your ride. As for maintenance, keep your bike clean. You can use a soft cloth to wipe off any dirt or dust. Store it in a dry place to avoid rusting, especially since it's made of metal. Also, be gentle with the handlebars and wheels to make sure they keep working properly. And remember, the individual bike models and ramp sets are sold separately, so you can choose the ones you like to build your collection.
