Bicycle Baby Carrier in Stem, Seatpost or Rack mounts

I’ve had this seat for several weeks and taken it on many short rides around the neighborhood and on a few two mile rides on the local greenway. Both my son and I like it.Installation was fairly easy. It clamps to the frame on the seat tube (not the seat post, but the tube below it). Four bolts and nuts are used to attach and tighten the two portions of the clamp around the tube. They provide an allen wrench (hex key) for the bolt. I can’t recall whether they provided a wrench for the bolt. I used my socket set for the bolt. They do provide bolts of two different lengths to support larger tube diameters. My mountain bike was at the top end of allowable tube size for the shorter bolts. I imagine oval tubes would work with the longer bolts, but I can’t be sure. Overall, the installation was quite easy. When I later found that I needed to lower the clamp a bit to allow the bike to fit on my car rack, that was also easy. The seat easily attaches and detaches from the clamp. This is convenient if you transport the bike on a car rack and need to frequently remove the seat.My 3 year old son seems to find the seat to be comfortable. He is always eager to join me and the “big kids” for a ride. He did mention after this evening’s ride that his helmet is bumping against the back of the seat. But we were riding on a gravel road that was a bit bumpy, so that may account for the complaint.I don’t have any complaints or cons with this seat other than I cannot mount my trunk or panniers when the seat is mounted. But that is no surprise. It goes with the territory with a seat mounted over the rear wheel.The seat does have a nice safety feature in that there is a guard inside the foot/leg area to prevent the child from putting his foot into the spokes.I’m glad I bought this seat. I would buy it again, and I recommend it.—-UPDATE—–After using this several times a week for several months, I discovered it had rubbed th paint of the seat stay on one side of my bike. The seat stay is the diagonal tube running from the top of the seat post to the rear axle. After careful examination, I saw that I had, in fact installed the seat slightly off center so that the protective shield that keeps the kid’s leg out of the spokes was rubbing one side more than the other. But the other side also had a tiny bit of paint missing too. So even if I had it perfectly centered, I would not have avoided the problem. And I was barely off. So close, in fact, that I decided not to try to adjust it,I ended up touching up the paint and then buying lizard skin patches to protect the frame. You can find them on amazon here:http://www.amazon.com/gp/product/B001CK0I9K/ref=oh_details_o05_s00_i00?ie=UTF8&psc=1They seems to have done the trick. Luck for me, that part of my bike is black. I see clear patches are also available. I recommend you apply something to protect your finish before you start using this seat.I do still like the seat and use it at least weekly.
