AZ Racing Stacyc Rear Disc Brake Kit - Semi-Hydro

Good kit. Much better than stock for braking power. Fixed the issue of little guy not being able to reach and pull in stock setup. Only thing I would add to kit is a small bottle of hydraulic fluid or at a minimum, recommend some hydraulic fluid to be purchased as well.

Very nice little kit. The options with the modes and speeds make it very easy for your little one to learn. Easy to install and get up and running. I would suggest cutting a small amount of the front brake mount post. Mine was hitting the battery bag when turns were being made.

Not only was the customer service great the product was above and beyond what we had anticipated.

This bike is so much fun! It rips I love it and it's quiet just got it from my birthday so I haven't been able to ride it much but it has lots of power

Recommend the semi disc brake, especially with the asv lever. Gives the stacyc a nice look
