Before you bike ride, adjust the seat to your height. To adjust, loosen the bolt on the stem below the bike seat. Lift the seat until it is approximately even height as your inseam, then tighten down the locking mechanism on the seat stem. Make sure you’ve adequately tightened the locking mechanism to avoid the seat falling or twisting while you ride.
For your scooter ride, kick start to get it up to speed first, then press on the throttle near your right thumb to accelerate. Familiarize yourself with the speed first. To ride safely, squeeze the brake to slow down when needed.
