Great quality product!!!

Santa brought my son this bike for Christmas. My son was not an experienced rider, but this bike has brought out his confidence and love for biking. Now looking at adult versions for my wife and I. I highly recommend this product and I plan on this being the first place I look for bikes in the future.

Want to love it as much as my grandsons do

I ordered two of these bikes for my grandsons for Christmas. They are beautiful (the bikes and the grandsons). However, one of the bike's inner tubes will not air up and the front breaks on that same bike will not adjust properly. The other bike is in perfect working order. I really wish they were both in that condition so both of my grandsons were happy.

At 100

I bought this bike for my grandson. Bike came by mail 90% assembled. My grandson liked it very much. The rear tire keep losing air. We are keeping an eye on that. It looks like some kind of leak.

Good starter bike

Wanted our son to learn how to ride a bike without training wheels and the height was perfect for him. I removed the pedals easily so he can learn how to balance and coast, and within an hour he was successful!

Great Bike Kids (Beginner)

Rockrider ST100 bike is sturdy with easy adjustable seat that's comfortable and suitable for my kids (ages 9-11) who just started to learn cycling without the supporting wheels. They pickup cycling less than 15minutes :)
