Electronic Bicycle - It's too crowded in city.
you don't need a big bicycle to ride.
these days smaller bicycle like a 'minibello'
is going to popular cause it's portable.
but when you ride in high speed small and
short bike is hard to get a center of gravity.
My Electronic Bicycle can change the shape from shorter one to longer one.
if you want to enjoy the speed, just make your bicycle longer and enjoy it!
if you need to ride in crowded and make it easy to carry, just make it shorter.
