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.
- The bicycle is taken out of the manufacturer's box
- The bicycle is assembled, inspected and adjusted (front and rear derailleur, shock, fork, wheels,...)
- The bicycle is carefully packed back into a box and shipped
- If you order a bicycle for in store pick up or home delivery, the bicycle will be waiting put together, checked and ready to use for you.
- If you order a bicycle via courier to your home address, the following must be done at home:
- Take the bike out of the box and carefully remove safety material and foils
- Mount handlebar to stem (1 minute, 4 or 5 mm hex hey is needed).
- Mount front wheel to fork (1 minute, without the need of any tools if the bike has a quick release).
- 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).
- 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).
- Mount seatpost to frame (10 seconds, without needing any tools if the frame has a quick link).
- Inflate the tyres or fork and shock to desired pressure (2 minutes, pump needed).
- Check the tightening of hex keys and quick-releases (2 minutes, 4 and 5 mm hex key is needed).
- 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.
