I had one, but we mostly used it for walks and the pedals were always frustrating for the kids. By the time they could actually pedal they wanted to use their bikes (with training wheels). We never actually converted it to a trike. Plus the storage part on the back of ours dragged on the ground which made it useless, I had to hang things from the handles. If I did it all over again, I'm not sure I'd get one.
This is the one we have. We use it for short walks. It has a cover for the pedals if they’re not at that stage yet but it’s annoying because there’s not enough storage so you’re gunna have to carry a bag and the handle is unbelievably low. I’m hunching over walking and if my daughter turns the handles, the whole thing turns and there’s no way to change that. Wouldn’t recommend it, but we use it because she’s just close to pedaling herself that we won’t need to use the handle. https://www.target.com/p/radio-flyer-4-in-1-stroll-n-trike-red/-/A-52810433
We got this one for my little guy. It converts to a regular trike or you can take the pedals off for a balance bike https://www.amazon.com/gp/aw/d/B0BT9CKSCL?psc=1&ref=ppx_pop_mob_b_asin_title
I’m following. I’m wanting to know the same thing
