Translation:I can no longer ride this bicycle because it is too small for me.
'I no longer can' and 'I can no longer' are both commonly used and correct. But here only the latter is accepted.
"I can't ride that bike anymore because it is too small for me" should be accepted too.
"I cannot ride THIS bike any more because it is too small for me" is accepted, and it should automatically be accepted with the contraction. However, the demonstrative pronoun tohle means "this," not "that."
