We have loved our bike! We got it so that one of our daughters (who has multiple special needs) could participate in bike riding too, and she has loved it! The other kids think its so cool, they always ask for turns too! The E assist is so helpful, i couldn't do all the leg work required without it. The interface is very simple to use, the ride is smooth. I was a bit nervous because I hadn't spent that much money on a bicycle before, but I have not regretted it. Worth every penny.
The only two things I wish we could change...
First, that there be an option for a one-person seat belt, not just the two kids set up. Our daughter with special needs is nine and tall for her age, so the seat belts (since they are made for much younger kids) don't fit her. The shoulder straps could almost fit, since they do adjust, but the bottom part that the two shoulder straps snap into doesn't. Also, there's only one connection on either side, and since she is so much bigger and takes up pretty much the whole seat, we would need a seatbelt that connects in the middle.
Secondly, I'm pretty short (5'4"), and the pedals are set a bit lower down (maybe to easier meet the back wheel for the E assist?). This means it is harder for me to reach the pedals, even when the seat is set as low as it can go. I have to pedal with my toes.
