My wife has one. It weights 60#. You get a work out when the battery dies. This one has three peddle assist settings. One of the things you have to learn to do is turn the assist OFF when you stop.
If you bring your top peddle down when assist mode is on and you are trying to stop; it will still go and run over you trying to put your foot down. It is fun to ride and gets about 30-40 miles a charge.
