    Poor quality control

    Both brakes rub against the wheels. I tried the easy fixes from support and those have not worked. I should not have to spend hours of my time fixing an expensive, brand new bike. Very disappointed in the quality control.

    I am trying my best to fix the brakes on my grandson's 20” bike. In my 75 years I have never encountered anything as upside down in design. The child brakes which pulls a cable to the rear tire, which in turn somehow pushes(?) pulls(?) another cable to activate the front brake. There are no available documents to guide in the assembly or correction of the assembly. The company did furnish my children with a broken piece; but even after the youtube video, it is not operational. There is something amiss with the back brake that does not activate the front when applied. I have decided to purchase another bike for my grandson and it will not be a web purchase or one without full documentation. I was fixing my own bikes at the age of 7 and it was easy and straight forward. Good luck! Remember, it is your loved one that is riding what you put under them.

    Late and Grips

    The delivery was late and the hand grips on the gear switch handle slide off.

    Hi, Thank you for the feedback. Apologies, shipping with fedex was delayed. We will follow up with fedex. We want all of our bikes to arrive within 1-5 days. A cool trick to get loose grips to stay on is to spray the inside of the grip with hairspray. This will prevent the grips from sliding off. It's a trick bike shops commonly use. Best, Sam
