ok im new to this forum i didnt search it sorry and its probably been asked before.
will someone who cant or never ridden a bike. throw your balance off if they were to jump on the bike with you?
my wife does not know how to ride a bike and sometimes when we've been to the shore i see rentals for tandem bikes and wondered would she throw our whole balance off with her not knowing how to ride or will my balance be enough for the both of us to ride? hmmmm
