somebody did the math .... besides the theoretical approach from the sellers ( and designers) and came to about 50 % isch.... now a regular old chain is about 95 isch ... or double .... meaning you have to peddle double as fast or hard to get the same distance as a normal bike .... than add the weight of that beauty ... rougly double than a normal bike .... you get the idea ? And yes if the battery os down there is nothing which moves the bike .... wonder if you can peddle standing still for an hour and than keeping peddling you might make it the next 5 miles before the battery is down again ....

hmmm ???
It sure is a looker though
