What is the weight limit on these training wheels ?
There is no official weight limit associated with these training wheels. These training wheels are designed for smaller children, perhaps around 40lbs - again, this is not an official number. If you are concerned about weight, you may want to look at some of the other options we carry. Two in particular you might want to look at would be item numbers K92-1657 and K92-1658, depending on the wheel size of the bike that will be used. You can find our other training wheel options here:
