I commute to work and ride around town rather than search for parking for as much as I can do. I did a lot of research to tote around my 28 pound, 22-month old son now that the awful winter is (hopefully) over. At my office bike parking, there are probably 4-6 different kinds of carriers/trailers regularly parked. I asked the owners for their personal feedback, and all were happy; however, the YEPP owners were both ECSTATIC. I now understand why! I struggled a bit with the price (especially because I had to buy a new hybrid-style bike to handle the extra load), but after using this for a week, I can say the peace of mind from having such a well-constructed and well-designed seat (and happy camper!), it was worth it!The installation was easy! I had a problem because I didn’t want to buy a bike which didn’t fit the seat, yet I couldn’t try it out before buying (I have a good relationship with my bike shop so I wasn’t especially concerned, but still…). The installation adapter had plenty of room for narrower or wider diameter tubing – no problem at all. Another concern I had was where to carry my lock, since previous U-lock holsters were in the same location. I found a different style of lock that fastens to the down-tube (I think it’s called).I ride on bike lanes in the city, and the bright orange YEPP seat seemed like the safest (yet not ugly – in fact, pretty cool looking) option for me. I don’t worry about not being visible, and the weight distribution was very easy to get used to. It would be nice if there was a clip or strap to clip my flashing rear light, but I fasten it to my helmet or backpack instead. I worried that my son wouldn’t get much of a view, or that my backpack would be right in his face. Fortunately the seat has a bit of a distance that leaning forward on flat handlebars seems to provide enough space and (so far) he’s so excited to be riding and waving to the pedestrians/traffic, it doesn’t seem to be an issue. Should be good for another year or two.Finally, the YEPP seat is so easy to remove/connect, that I have no problem removing it for my typical solo commute and re-connecting it on the weekends or evening rides, as needed. One caution: the adapter may cover your saddle screw, so make sure your saddle is adjusted exactly where you want it before you install the adapter — otherwise you may need a bike shop allen wrench with little clearance to make adjustments.I’ve already recommended to my brother and neighbor who have similar size/age kids, and really am thrilled with this purchase!

My husband might hate me telling this story, but here: we bought this at his urge because: oh gosh, awards, colors, reviews it looks way better than the other seats we kept browsing. I was reticent of it, it was just a bike seat, what’s the big deal? We decided his bike was better since he has better agility and balance than I do.Well, on our second use, while I was ahead of my husband I slowed down to ask him what road to take on a fork ahead of us, he slowed down and veered to our right, then sped up in front of me. To my motherly horror, as soon as he gained that speed, the whole seat came off, with our son on it, while his arms looked like flailing spaghetti.I have no idea how the crap I got off my bike without falling while I was still riding it. I screamed, I heard my son cry: MAMA, MAMA, MAMA, his seat rolled thrice, and all I thought was: his face is gliding on the pavement, his knees are scraped. He’s grated cheese.My husband stops, I reach my son, I pick him up, he’s bawling in fear still crying mama, mama.I take a look at him and he’s whole, with ONE small scrape on his knee. That’s it. He had a helmet, which helped him keep his face off the pavement. The locks on his feet helped keep his legs in place, the foam-rubber sides kept him cupped safely inside his seat.The seat came off because my husband had put the wrong side of the lock from the seat onto the base on the bike. Basically the dang seat was never attached and the inertia from his slowing down, his turn and his speeding made the seat come off. So, please pay very close attention to hearing that “click” sound when securing the seat to the base. Also, always make sure your kid has a helmet. I was so tempted of not putting the one we had that day because it was way too big, our ride was less than half a mile, it was in a closed off walkway, and my son was fighting putting the helmet on. Then I thought: it’d be really crappy if your husband falls off and your kid hits his head.So, I’m glad I got that seat, my son was cocooned safely in it, and always put a helmet on kids. Even if you’re biking 10 feet.

My 2 year old daughter and I were bicycling up the street today for a trip to the park. A car clipped my handlebar as it tried to pass us. Probably doing about 25, at least that’s the speed limit there though people speed. I literally didn’t know what hit me initially. I’d heard the guy behind me accelerate, like he was going to move into the left lane and pass me, but traffic was very dense, he cut it way way too close, and he actually hit me. Not sure what he was thinking, particularly given there was clearly a child on the back of the bike. And then he sped off (someone got his plates and had a dash cam, so with a little luck he won’t be doing that to someone else any time soon). It took me a second to realize what happened– probably way too many seconds actually–and to try to gather us up and out of the road. Thank God the next guy was able to brake pretty fast. I got us out of the street. Daughter was wailing, but aside from one little scratch on her knee — she’s fine!!! I was pretty banged up, but when the ambulance came we actually turned down the trip to the hospital. This thing, and a helmet, may well have saved her life. It’s well engineered to (1) stay on — it was knocked sideways but still on the bicycle frame; and (2) envelope a kid properly to protect him/her. I already would have recommended it had someone asked me, but this left me thinking I should write a positive review. This is a product the manufacturer should be proud of.

Bought this seat thinking it was the same as the Thule Yepp Maxi on the RadPower Bike website. The necessary seat is the “Thule Yepp Maxi Rack-Mount Child Bike Seat”. Will be returning this and have ordered a compatible seat.

This is a quality seat and my daughter loves riding on it. I like the bright orange and the quality feel of the seat. Only improvement is that my vertical bar (under seat post) is a bit slanted back causing the seat to sit slightly too upright. They assumed this bar would be 90 degrees.
