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.

Variant DEMA Ergo 29 elektrobicykel, light steel blue/black

SK Bicykel faj, bez vážnejších problémov, ale......
Ukazuje sa ,že slabinou bicykla bude stojan. Mal by byť posunutý min cca 2cm ďalej, nakoľko pri pedalovaní sa mi stávalo , že som oň zachytil pätu topánky. Kamarát z bezpečnostných dôvodov si už musel stojan odmontovať. Uvidíme ako často bude dochádzať ku kontaktu cyklotopánky o stojan .

Variant DEMA Ergo 29 elektrobicykel, anthracit/silver

Hello, I have a Dema Ergo e-bike. I found out that there is a steel nut with three pawls, 2pcs 6902 bearings. The question is - what kind of nut is it and whose spare part do you have it for? Thank you

SK Dobry den,

zial na tieto OEM naboje neexistuju blizsie specifikacie, okrem zapadiek (ich poctu a tvaru) moze byt odlisne aj samotne telo orecha, jeho kovanie v miesto dosadania na telo naboja a pod. - samotny orech tak odporucit nevieme, zvacsa sa v takychto pripadoch prepleta koleso na novy (kvalitnejsi) naboj
