I dropped off my bike.

Can I say "I fell down from my bike?"

Many thanks~~

ı can understand u :) so ı thing u can

yes, i think you can..

I fell off my bike.

 I dropped off my bike = I left my bike somewhere on purpose, so that someone could use it or repair it.

for instance:

I dropped off my bike at my friends house (so he could borrow it).

I dropped off my bike at the repair shop (so it could be fixed).

Or another example:

I dropped of the books at the library.

Thanks for all of your repsponse.

And can I say :"I fell DOWN/FROM my bike"?

I read the sentences in the dictionary  like"Be careful lest you fall from that tree." &"I was black and blue after i had fallen down the stairs."

yep you can even say I fell down from my bike.

yes,I think :P

feasible

good ,when i was a child ,i had fell off my bed

dadong

I think "When I was a child, I fell off my bed for many times."   would sound a bit better.

thank you ,but 我只掉下来一次，怎么说啊
