This looked like a great bike at first, but after my son rode it for a day, one of the pedals detached and we cannot screw it back in place (the thread is broken.) I contacted customer service, who promesses that the Cycling Manager would call me (they set up a meeting time with me), but no one called. We are very disappointed and do NOT recommend this bike. Customer service gets an F since they failed to contact us... Now we are stuck with a bike that’s useless...
The only thing my son did not like was the grip shifter. It makes his palm quite painful after riding and the up shifting is not smooth. Otherwise, this is 100% worthy for entry level MTB.
Thanks for your honest opinion on the grip shifter on the ST100 24" Mountain bike. Yes I agree that the supplied entry level grip shifter is stiff and not the easiest for kids to use. You could try our kid's gloves @ https://bit.ly/2Do2sxX to add comfort to your son's palm.

I lived in France and rode Rockriders. It's a good, solid bike. The brakes and derailer we're we'll set up on arrival. My only complaint is that it doesn't have a suspension fork.
Me parece que hice una muy buena compra para mi hija, hay más baratas en otros lados pero ésta es muy solida, ligera y cero ruidos. Estoy contento con lo que obtuve por lo que pagué.
excellent vélo, je le recommande vivement !!!
- 100% Steel
Our engineers have designed a new sturdy steel frame. The frame's rear chainstays are short, making the bike responsive and easy to handle.
2 V-Brake pads for effective braking. These brakes are composed of calipers that exert more or less pressure on the rim to slow or stop the rotation of the wheels.
This bike is equipped with a grip shifter to change between the 6 speeds: It's a safer and easier system for children so they don't need to let go of the handlebar. This makes changing gears to match the terrain simple and easy!
A saddle with a sporty design, designed with care to adapt to the morphology of children. It is equipped with a plastic cover at the back (a bumper) to protect from any potential impacts.
To provide you with maximum comfort, this mountain bike is equipped with a high-rise stem. Your position on the bike is slightly raised so you can better anticipate your trajectory.
The new chainset has a 152 mm crank that is designed for a child's leg length. This chainset allows you to start pedaling more easily. The double chain guard prevents the chain from derailing.
To transport the bike, we’ve made it easy to remove and attach the front wheel. It is equipped with a quick-release system. The tires are designed for mountain biking. The side lugs provide good grip for cornering. The recommended tire pressure is indicated on the side of the tire (2 to 3.5 bars). 24" inner tube, 1.7" to 2.2" Schrader valve.
This MTB is equipped with a bell, lighting, wheel reflectors and platform pedals. The frame is also compatible with other B'Twin accessories: - front and rear mudguards; - stand; - bottle holder; - bike bags; - stabilizers
Length: 63". Height: 39.4". Width: 22".
Store the bike in a clean, dry place. Clean and grease the chain regularly. Our tips for before each ride: inflate the tires to the pressure indicated on the sidewall.
