Product Reviews


Really pleased with this bike. Very well built and comes with front and rear lights. The team at the Rushden Lakes store made sure it was safety checked and ready to ride...so thanks for that! Also has quick adjust saddle which is an added bonus. Bought for an 8 yr old and he is really happy with it.
So happy to know you are satisfied with your bike and the service our team provided. Don't forget to come back for your 3 months free service soon!

Велосипедът е чудесен. Като цяло не отстъпва на по-скъпите на пазара. Единствен недостатък - малко по-тежък.
От всички най доволен е синът ни.
Kolo super, ale mohlo by být levnější
Velmi doporučuji. Skvělé kolo za dostupnou cenu.
Nevýhoda je, že řazení je velmi těžké a 6 leté dítě nemá téměř šanci používat převody.
Perfektní kolo na krátké výlety, máme jako druhé na chatě a úplně dostačující. Jediná nevýhoda je váha. Součástí jsou přední i zadní světla. Oceňuji ochranu přehazovačky!
Syn je naprosto spokojený
Kolo v pořádku jen jsem při vyzvednutí déle čekal omylem mi připravili jiné kolo toto museli teprve smontovat...
Z kola panuje nadšení.
doporučuji. Rozhodně vynikající poměr cena/kvalita.
Jsme spokojeni, za tu cenu dobrá koupě.
Hezké kolo a ještě za dobrou cenu ;)
Syn vůbec neuměl jezdit na kole tu sedl manžel ho chvilku držel a ejhle syn jezdí suuuuper
Velmi dobrý
Additional Product informations
Composition
Frame
- 100% Steel
Frame designed for mountain biking
Our engineers have designed a new, robust steel frame. The frame's rear chainstays are short, making the bike responsive and easy to handle.
Why have we created a brake lever specifically for children?
Because children have smaller hands than adults, it's not always easy for them to reach the brake lever. This is why our engineers designed a brake lever that is closer to the handlebars and thus easier to hold.
Changing gear
This bike is equipped with a grip shifter to change between the 6 speeds: an easier, safer system as the child's hands stay on the handlebars.This makes changing gears to match the terrain simple and easy!
Controlled braking
Two V-Brake pads for effective braking.These brakes are composed of callipers that exert more or less pressure on the rim to slow or stop the rotation of the wheels.
A reinforced, ergonomic saddle
A saddle with a sporty design, designed with care to adapt to the morphology of children. It is equipped with a plastic section on the rear (a bumper) to protect against any impacts.
Riding position
When mountain biking, it is important to control your path. To make it easier for children to learn, our engineers installed a handlebar and stem that are combined into a single steering block. This eliminates the needs for adjustments, so they can stay focused on the road!
Crankset
The new chainset has a 140 mm crank that is designed for a child's leg length. This chainset allows you to start pedalling more easily. The crank is covered to prevent the child from coming into contact with the metal part.The double chain guard prevents the chain from derailing.
20" wheels and mtb tyres
The tyres are designed for mountain biking. The lateral lugs provide good grip on turns.The recommended tyre pressure is indicated on the side of the tyre (2 to 3.5 bars). 20" inner tube, 1.7" to 2.2" Schrader valve.
Mtb fittings
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 cage- saddle bag- stabilisers: https://www.decathlon.co.uk/20-and-24-stabilisers-id_8550741.html
Dimensions of the bike ready to use
Length: 140cm.Height: 80cm.Width: 54cm.
What if i order online?
For smoother shipping, our bikes come with their pedals removed and the handlebar unscrewed (instructions and tools are supplied)
Frame dimensions
Top tube length: 431.6 mmSeat tube length: 285 mmChainstay length: 360 mmSeat post length: 300 mmHead angle: 68.8°
Photos non binding
For the drive train parts (freewheel and derailleur), the photos or videos provided on the product description show a Shimano derailleur and a Spark freewheel. However, because of procurement issues, an equivalent, derailleur and cassette from a different brand may be present on the bike.
