Good quality budget upgrade
Our upgraded from 14" to 20", They're just almost reaching 120cm and once on the move, they're enjoying riding noon stop, Perfect for them for probably another 3 to 4 years use?

Ok but needs improvement
There is no adjustable headset. The handlebars are welded, fixed to the stem. That's pretty stupid for a bike meant for growing children. I replaced the stem and bars and now my daughter loves the bike.

    A fun and easy to ride bike for kids.
    My 7 yo son loves this bike. The Rock Rider ST100 is so fun to ride that he quickly forgot about the older bike that he initially did not want to give up. This bike did not come with a kickstand so order one separately if it's something important to you.

    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 :)

    Formative years cycling experience!
    To get the confidence level up for a 5/6 yr old I switched from a training cycle to this 20” and she just loved it. A father-daughter Saturday morning cycling and jogging ritual.

    Excellent price and service
    I went to Decathlon to buy a bike for my 8 y.o. son. without any particular preference other than to get an affordable solution. Once in the store, I was pointed to the bike I ended up buying. The staff advised me on size, which I would have possibly guessed wrong, and price. This was the last piece in the store at the lowest price. They set up everything very quickly and I left the store quite satisfied with the bike and the service.

    no rest stand!
    Buyers should be alerted that bike does not come with a rest stand, which all the bicycles we have bought before has - especially for a kids bike. only realised upon delivery. shld be part of bike! otherwise, decathlon should at least alert buyers in the shops (where we tried out the bikes, and all there had stands!) or on the specs section pre purchase. cheers
