Topeak BabySeat II Bike Rack, Disc or Non-Disc Brake Bikes - 26", 27.5", 29"

I bought the topeak baby seat unaware it would not fit on my bike. Once I attempted to install the seat I learned the rack was not large enough to fit on my 29 inch tire. This rack made it fit and my son loves the seat.

I have used three of these in three different MTBs (trek marlin). These bikes are used for commuting in very hostile conditions (tropical rain forest and beach front in Costa Rica). The racks works perfectly fine to carry my 8 year old girl or to carry heavy grocery bags (I use the rack with a child seat or with a Topeak basket).

I have this brand of rack on my 27in mountain bike, but I recently bought a 29er. On my 27in mx bike, the rack (the 27in version) provides much more clearance between the rack and tire. See the 29er version clearance in the picture. This may just be my bike. It doesn’t rub that I’ve noticed, but I wish there was more space. Also, I purchased the longer arms and that made all the difference. I don’t think the bike seat would work on my bike using the attachment arms that came with the rack. It feels really sturdy though and I love this bike seat for my little one!

finally - I can put my baby seat on my 2013 rockhopper comp!This may work on other size bikes. If you haven't installed one before - go to a bike shop. you can mess up your threads, esp on aluminium.

I have Trek Roscoe 7 and tried to install the topeak child carrier on it, it 27.5 inch so I bought the 27.5 inch rack and did not fit! the rack is right on top of the tire! so there is no way for it to move, then I tried the 29 inch rack to have move room on top my tire, now the bracket does not reach the bike frame, so with a lot of trying I was able to extend the bracket by attaching another one to it, at the end it worked but with a lot of afford. Summery: this would only fit the 27.5 inch mountain bike, also you will need to buy the extra Long bracket, the standard one won’t reach the bike frame!

We are on vacation and purchased the Topeak child seat which has a rack that does NOT fit a 29 incher - it just sits on the tire! So, we did some research and learned that we need a bigger rack that is specific for a 29'er AND disk brakes. A pain, but we order the specific rack for the 29'er. We wait for nearly 5 days for the item to arrive. Thank you amazon for getting it to us 1 day early!So excited to put this new bracket on and get riding with out little one. Oh, wait, there's barely a millimeter of space between the top of the rack where the child seat sits, and the tire! This cannot be safe with a CHILD on the back?!Research further and it seems we also need the extra long arm brackets to install this. Those extra long arm brackets that fasten to either side if the frame under the seat (horizontally), do NOT come with the original product. They also do NOT come with the 29 inch larger bracket- are you kidding me? Insane amount of hassle. Start providing the longer arm brackets with the 29 inch!! You know the child seat requires them to give the bracket and seat enough clearance over the tire! Not to mention, it's not like we are transporting a block of wood here, we are counting on Topeak to give us a SAFE and reliable method to ride a bicycle with our precious children!I have called the 1800 # to get customer support and no one answered. The option was to leave a message for a call back, which I have done.Enormous disappointment and infuriating that we spent hundreds of dollars to be able to go on a family bike ride that cannot happen due to Topeaks failure to provide the appropriate support brackets!

We use this with the Topeak Child Seat and LOVE it! It's durable, well built and easy to move the seat on and off onto our other bike. Easy enough to install.

I have this seat on the back of my bike with a Bobike mini on the front--I love it! Of course, I didn't install it my husband did. He had it on and ready to go in about 30 minutes. My child loves to be out of that stupid trailer and loves to be able to feel the wind on her face. Once strapped in your child is super safe and they will love it!
