After receiving this seat and an infant bike helmet one week ago, had it attached within 5 minutes, and have used it several times with my 12 month old daughter. I am 5'3" with a small-medium build and have had NO PROBLEM reaching the handle bars around her. I have a ladies' mountain bike so maybe it would be difficult with bikes with smaller handle bars. I also have no problem getting on and off the bike. The first "take off" was a little awkward but now it is a breeze. There is adequate room between the ibert seat and my own seat. My daughter loves riding with me and can tolerate about 20 minute rides so far before she starts going crazy with the helmet and trying to tear it off. I LOVE, LOVE, LOVE this seat.
