Considering most decent bikes at this price range are out of stock - this seems like good buy.
Great for keeping fit during lockdown.

5 sizes available in either yellow or grey (limited)
See youtube videos. Very well reviewed bike at a good price.

*** Due to the number of people ordering bikes at the moment / ability to keep up with demand, they only take a limited number of orders each day. Therefore, wait the best time to order is between 11pm and 1am otherwise no chance of getting a slot. ***

Faturing a CGF frame with upright rising position, 21 speeds, 80mm suspension, ErgoFit hammock saddle with Flex seat post and 27.5-inch wheels, it provides control, durability and comfort in equal measure.
  • Light and rust-free alloy frame
  • Grippy tyres and V-brakes
  • Available in different sizes

WHAT SIZE MOUNTAIN BIKE TO CHOOSE?

Several sizes available:
XS: between 1.40m and 1.54m
S: between 1.55m and 1.64m
M: between 1.65m and 1.74m
L: between 1.75m and 1.84m
XL: between 1.85m and 2.00m
To adapt the bike to your height and size, try these tips:
1/ Sitting on the saddle, you should be able to touch the ground with the tips of your toes.
2/ To find the right saddle height, your knee should be slightly flexed with the foot on the pedal in the lowest position.
3/ If you're between two sizes, choose the larger size.

UNISEX FRAME
With a very marked slope on the top tube and a wide range of sizes (from XS:1.45m to XL:2.00m),
The ST 100 mountain bike frame is UNISEX.
TheST 100 mountain bike exists with the same frame in a WOMEN'S version: adapted seat, narrower handlebars, shorter stem, fork with a more flexible spring, and brake levers that are closer together.
As a WOMAN, if you choose the MEN'S model, we recommend at least purchasing the WOMEN'S SPORT 500 saddle which is adapted to women's body types.


A WORD FROM THE TEAM
We created this ST 100 mountain bike at our B'Twin Village (Lille, France) especially for mountain biking enthusiasts.
Recreational mountain bikers told us they wanted comfort, effectiveness and durability. Those features were our starting point as we designed, developed and tested the ST 100 mountain bike, with real riders involved throughout the project.


A LIGHTWEIGHT, COMFORTABLE, FUN FRAME
It isn't always easy to get the right position on a mountain bike. Our designers have
created an entirely new frame that is easy to step over.
The 100% aluminium CGF frame (Comfort Geometry Frame) is both comfortable and easy to handle. The slope angle has been designed to keep your back straighter whilst the rear has been shortened to ensure the bike is very agile when turning.


FRONT SUSPENSION
The 80 mm front suspension helps you overcome your first obstacles on slightly uneven trails with no worries. Its mechanical spring is a stamp of reliability. And the fork is particularly easy to maintain. To adjust the stiffness? It's very easy using a single dial.

REAR SUSPENSION: NONE
This mountain bike has no rear suspension.
It is a "hardtail" mountain bike: perfect for beginners launching themselves into their first mountain bike touring rides.
Compared to a full suspension mountain bike (with rear suspension), the advantages are clear: the mountain bike is lighter; you expend less energy on flat ground.


DERAILLEUR & DRIVETRAIN:
3 x 7 speed chainwheels, 21 speeds total!
2 easy-to-use grip shifters on the handlebars.
Left (chainwheels): control ascents/descents.
Right (speeds): more precise control over your pedalling.
In detail:
-Triple-chainwheel chainset (22/32/42 teeth)+ anti-grease protection.
-Microshift FD-M20 front derailleur
-Microshift RD-M25 rear derailleur
-Microshift MS25 grip shifters with speed indicators
-Shimano TZ500 7 cog cassette, 14 to 28 teeth
-Large, solid KMC Z51 chain


HANDLEBARS, STEM, GRIPS
With a stem that tilts 10° upwards, the riding position of the ST 100 is raised, accessible, and comfortable.
In detail:
- 90mm (in sizes XS and S) or 110mm (in sizes M, L and XL) aluminium stem with an angle of 10° for maximum comfort
- 620mm-wide steel handlebar, for stability and control
-"Soft touch" grips for a firm yet soft and pleasant grasp.

SADDLE
The saddle of the ST 100 is welded to prevent any movement of the saddle.
And because your comfort is our next priority after safety, we've added an exclusive wider Ergofit saddle with a hammock shape.
Easilyadjust the height of your saddle with the Flex steel seat post, either350mm or 400mm long (according to the bike size). Its reduced diameter of 27.2mm provides your seat with natural flexibility, 30% more than a standard solution.

V-BRAKES WITH PADS
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.
Thanks to the special design of the ST 100's aluminium brake levers, you only need two fingers to brake.


27.5" WHEELS & TYRES FOR DRY TERRAIN
The wheels of the ST 100 are tolerant and robust, with 27.5" double-walled 28-spoke rims (26" for the XS size). Slow down without worrying about obstacles: small rocks, cracks, holes and bumps!
Because your first rides will be on dry ground, this mountain bike is equipped with DRY 27.5 x 2.0 tyres. Their performance has been optimised thanks to a faster central section, while their side lugs offer excellent traction in turns.


PLATFORM PEDALS
The Rockrider ST 100 mountain bike is supplied with hard resin platform mountain bike pedals for added lightness and safety.
If your foot slides on the pedal, there's less risk of injury.

TRANSPORT & STORAGE
We added a quick release system for easily removing/reattaching the front wheel.
There is a nut at the back to secure the bike and limit the risk of theft. You will need a spanner to remove the rear wheel.
Tip: a bike rack is an easy way to transport your mountain bike without dirtying your car.

ACCESSORIES
Your ST 100 mountain bike comes with a derailleur guard, chainwheel guard (to prevent your clothes from getting dirty), bell, lights, wheel reflectors, and pedals.
The frame is compatible with:
- Front and rear mudguards (Flash MTB or MTB 700)
- Stand (500 Adult Base)
- Bottle cage
- Saddle bag
- Rear pannier rack
- Child seat (depending on the model)
...

COMFORT & SAFETY
Your bike's fittings (chain, derailleur, brakes, etc.) will adjust over time. Take advantage of a free servicing within 6 months after purchase. Our technicians will carry out a 13-point check of your bike. Just come to your nearest Decathlon workshop with your Decathlon card and/or receipt.

Riverside 900 from Decathlon. (When it comes back to stock)


Why not strada 2 commuter at 300?
JonSno02/05/2020 22:37

Just personal preference and returns policy.


What's the returns policy?
Are these hard to put together
Bell sold it to me
When I see one of these on the street it always makes me think Cxxxrider for some strange reason, much better to buy one of the lovely new Carreras at halfords.
Cxxkrider
Voting cold as this is the normal price. Bought for my son about a month ago having just missed out on it being £159.
For anyone considering a bike from Decathlon, due to the number of people ordering bikes at the moment / ability to keep up with demand, they only take a limited number of orders each day. Therefore, wait until just after midnight otherwise no chance of getting a slot.
I am embarrassed to say that I don't know how to work gears properly...

They arrive pre-built in a huge box. Just take it out of the box, adjust the handlebars, add the pedals and you're ready to go.
