Question: anyone knows the weight limit?
Document: The metal frame is a little heavy and our son, at first, had trouble just trying to move the weight of the tricycle. But over time, it has help build up his leg muscles and now it is a joy to see him pedal as fast as he can with his little legs, telling us he can &#34;go fast&#34; on his tricycle. This is probably the best low maintenance, outdoor product we have ever bought for him so far!
very sturdy and perfect for my 3 year old. We have this and Radio Flyer and we prefer this one!
the German quality is outstanding. Easy to assemble and the 1 year assisted every step on the way as she could not wait to get on her first bike. The seat belt and push rod ensured a safe and quick use of the trike.
We've not had any problems or complaints about the plastic parts. Our Kettler came with the parent bar, which is a life saver at times when our son becomes tired or when we go up steep hills. We love how you can lock the front and/or back wheels so our son can steer himself, or we can steer for him from the parent bar. The removable basket is great for carrying keys, our mail, water, small bags, etc.
We will be getting MANY MANY safe years of play out of this trike.
We registered for this trike when our first kid was born. Though well-built and adorable, this trike is one of the heaviest and most useless things in our apartment. And ours is not a large apartment.
We have this trike, along with tandem add on seat for out twins. They used from 1 to 4 years old, and thought it was a blast and fun alternative to the stroller. After three years living outside it still looks and works like new. Serious quality and must for multiple kids!
We had done our share of reviews when we first looked into tricycles for our child, so when we bought the Kettler, our expectations were pretty high, especially for its price. We bought this for him when he was about 1.5 years old, and after a year and a half, this tricycle has well surpassed our expectations.
This was a good deal at $169 and assembly was easy but it came one screw short (for seat belt). Grips and wheels came pre-installed, which was appreciated. The little one can't peddle yet, but likes it nonetheless. I would like the guide handle to be a little more stout, but it is effective, as is the rear wheel steer.
This is an all-around great product. We got it this summer for our 2.5 year old son. We use the handle on the back and can push him around when we go for walks...instead of pushing him in the stroller. It's very sturdy and safe - and it was highly recommended from a friend - and it's worth it. It's not going to tip over, it's not all wiggly, it's not crappy plastic like so many others.
