I'm looking into an electric assist bike I can use for a 4.4 mile commute with a 3 year old in a rear rack mounted seat and a 5 year old in a trailer, along with various backpacks, etc. I am an average-sized woman and we would have to go up one fairly long hill during our ride and a couple shorter, steeper hills. I'm totally happy to pedal to assist the motor, so I don't expect to do no work, but I absolutely can't do it with that weight on my current, non electric bike. Any thoughts on the EG Athens? I like the price and features.
