[AJUDA] Movements

Gente eu tenho aqui uma script simples de bike e uso ela no slot  9 "ring" mas quando estou usando ela eu posso retirar ela do slot e joga-la fora, eu gostaria que enquanto eu estivesse usando ela ficasse sem poder se mover para evitar usar e emprestar para outros jogadores, alguém poderia me ajudar, eu tentei editar no movements o dequip mas não consegui.
