All bicycles at the MTBIKER shop are new, not-ridden, from an official distributor and with a full warranty. Several brands even offer a lifetime warranty on the frame after registration. We perform all warranty services in MTBIKER stores after personal delivery or after sending the bike (or its part) by courier.

Our bike shipment is as follows:
  1. The bicycle is taken out of the manufacturer's box
  2. The bicycle is assembled, inspected and adjusted (front and rear derailleur, shock, fork, wheels,...)
  3. The bicycle is carefully packaged back into a box and shipped
  4. If you order a bike for in-person pick-up or home delivery, the bike will be waiting for you assembled and checked
  5. If you order a bicycle via courier to your home address, the following must be done at home:
    1. Take the bike out of the box and carefully remove safety material and foils
    2. Mount handlebar to stem (1 minute, 4 or 5 mm hex hey is needed).
    3. Mount front wheel to fork (1 minute, without the need of any tools if the bike has a quick release).
    4. Loosen the screws in the headset, straighten the stem with the front wheel, tighten the upper screw on the fork and then tighten the headset (2 minutes, 4 or 5 mm hex key is needed).
    5. Mount the pedals to the cranks while lubricating the thread and carefully mounting it the right way (1 minute, 8 mm hex key or 15 mm wrench).
    6. Mount seat post to frame (10 seconds, without needing any tools if the frame has a quick link).
    7. Inflate the tires or fork and shock to desired pressure (2 minutes, pump needed).
    8. Check the tightening of hex keys and quick-releases (2 minutes, 4 and 5 mm hex key is needed).
    9. Go for a test drive! Handle your bicycle carefully until you get used to it. If the bike has disc brakes, their performance will be limited from now on - they will gain their full power after 4-5 strong brakes at higher speed.

The ratio of the price and equipment of the components is indeed very decent, maybe even the best ratio when I take the VIP price into account.
Carbon frame and carbon fork plus carbon handlebars and telescopic seat post, all components GRX 810 and above.
But there is one big but, I have exactly the same problem as a CPK user, and that is that the seat post is constantly falling. I solved it with the first complaint, where they said that they used carbon paste, but after 40 km it's exactly the same and the seat post keeps falling.
Plus I have one more problem, something is constantly creaking there, and I also received a statement that it was lubricated and the creaking no longer appears, but now it has started to crack again.
I'll send the bike back on Monday for a claim, but the bike can't be used like this and I'm only giving it one star because of the sagging seat post.
I recommend not buying this bike, at most if a new revision comes out, or they change the mechanism for attaching the seat post.
I am also sending a photo, the first photo was taken directly in mtbiker after the first complaint.
The second photo is after 30 km and I told myself that it is still quite decent.
The third photo is after another 5 km and it's all the way down there.

SK Čaves, ja som mal presne rovnaký problém s padajúcou a pukajúcou sedlovkou na Giant Contend AR2 2021. V Giant servise mi to odmastili, vyčistili a utiahli na 7Nm (o 1Nm viac ako sa požaduje). Po asi dvoch dňoch mi to začalo pukať…už to nepadalo ale pukalo. Po dlhom skúmaní a skúšaní mi pomohlo celú sedlovku vybrať, vyutierať do sucha vreckovkou, namastiť vnútro + sedlovku pastou Muc-Off Carbon Gripper a dotiahnuť na 7Nm. Okolie som olepil izolačkou, aby sa tam nedostali nečistoty (z toho to pukanie) a musím poklepať, zatiaľ drží. Možno to pomôže aj tebe.

SK Je dosť možné, že tento problém je len pri teleskopickej sedlovke, ale nepotvrdím ti to.
Nakoľko aj táto recenzia https://www.mtbiker.cz/clanky/125555/test-rock-machine-gravelride-crb-900-axs-kamarad-pro-vsechny-napady.html
čo bude nová rada možno pre rok 2024, tak mala nejaký problém s teleskopickou sedlovkou, posielam priamo z danej recenzie: "Na tento test jsem se velmi těšila. Poprvé jsem se s GravelRide 900 setkala již na podzim, kdy mi byl zapůjčen, ale kvůli technické chybě uchycení sedlovky jsem kolo po 2 dnech musela vrátit"

SK Presne pred rokom som kupoval CRB 700 a so sedlovkou problém nebol, mne pre zmenu pukal ježko čo sa reklamáciou vyriešilo.
Možno vám moja skúsenosť pomôže

SK Tento zvuk išiel zo stredového zloženia, toto už nespôsobovala sedlovka, preto aj daná odpoveď priamo z mtbikeru: "Vrzganie mohlo byť spôsobené nasucho nakrúteným stredom alebo patkou. Obe boli namastené a vŕzganie sa už neprejavovalo."
A trochu to aj pomohlo, lebo predtým ten zvuk bol ozaj dosť horší, ale stále to bolo počuť.

+ Decent frame, filters vibrations quite well, but is also quite strong
+ The color of the frame looks better than the name, it is matte, I took size L (my height is 178 cm) and it fits just right

- Regarding the brakes, I previously had a GRX BR-RX400 and they braked comparably if not better
- Problems with the seat post. After riding about 50 km, it fell by 1 cm (I weigh 75 kg), so I sent the bike for a claim.

Edit (19.05.2023):
- After the first complaint, the problem with the seat post became even more pronounced - I sent the bike for a second complaint.

Chtěl bych koupit kolo na firmu v ČR. Platba by byla možná v CZK i EUR. Kolik bude stát doprava kurýrem do ČR?
