UPDATE: Almost exactly a year to the date, another bike broke, which now makes a total of THREE BROKEN BIKES. Like the other two bikes it just broke for no reason. One moment my kid was riding the bike, the next she was sitting on the ground because the spring broke. We never ever switch her bike to scooter, knowing that there's a chance it could upset the temperamental spring. Awful awful awful. You're better off buying either a bike or scooter because at least they would work. I will never purchase anything from this company again. PREVIOUS REVIEW: Ordered two of these in April 2020 for my twins' birthday. Less than a week later, having only been ridden once for a test drive, it broke - spring issue just like in all the reviews. I contacted customer service asking if there was some sort of replacement part or way to fix the bike and a week or so later they replied with a canned answer/email. Essentially fill out the RMA, we'll be in touch. There was no level of customer care or explanation on the return process, or even a way to simply fix this on our own with a new part. Surely they must be aware, based on all the negative Amazon reviews, that this is an issue. Not only did we have to tell our kids that they couldn't play with their birthday gift, but we had to tell one that their bike was broken. Since the bike broke almost immediately, we returned it via Amazon as it was clearly a faulty item. Six months later, another bike has broken - same spring area. Because we knew of the spring issue previously, we rarely, if ever, convert the bike from bike to scooter, and we have treated them with kid gloves. Still, it broke, and it broke while my kid was casually riding it, sending him to the ground. After our previous encounter with customer service and after reading what they charge to repair their bike, we'll probably cross our fingers and attempt to fix the bike ourselves. One broken bike I could chalk up to an fluke, but two in less than a year? And both with the same issue? That's a major design flaw that needs to be addressed. I expect many of these bikes get tossed once they break - either by the owners or by the company - and that also doesn't sit well with me, especially if it's a part that can simply be replaced. Swagtron should recall the bikes. Poor craftsmanship, poor customer service, and dangerous. Great idea, but I would never buy these bikes again, nor would I ever recommend them unless they resolve the above issues.
