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 Beast 29 elektrobicykel, metal blue/black

Amazing electric bike for an amazing price, the price-quality-performance ratio is top. The color is beautiful metallic blue with yellow-green accessories. The bike's equipment is sufficient even for high-mountain trails. It is suitable for both men and women. I rate the pluses that the battery can be removed and charged. The battery is a great help in high hills. The suspension is ideal, it can also be adjusted individually. The pins on the shock absorber creaked a little at the beginning, but somehow it settled down over time. The only minus on this bike is the seatpost is terribly hard and after a long ride you feel like you are sitting on a board.

SK A ešte si treba dať pozor pri full vytočení do prava, kde sa vytlačí poistka batérie vrchom vidlice, inak za tie peniaze, krásny a funkčný bike. U mňa láska na prvý pohľad a veľká spokojnosť 👍 sedlovku som už vymenil 🫣

Variant DEMA Beast 29 elektrobicykel, metal blue/black

My first ebike transition from XC, so my initial joy remained high even after 400km. The seat suits some, some don't, it's individual, they fit narrower for me, so the first and only change came. As a bottle I have a stand with a magnet, which is a great idea, due to the narrow place at the top of the frame. Maybe not even a minus, but rather you need to be careful with the battery fuse, when you turn the wheel fully to the left, the top of the shock absorber catches it and moves, just an observation. In short, for me a great bike.

Variant DEMA Beast 29 elektrobicykel, metal blue/black

I recommend 10/10 in terms of equipment and comfort, you can't buy anything better for the price. The engine pulls well and the battery lasts 90-120km without any major limitations.
I have to repeat myself again... unbeatable price for this equipment and used components, I am extremely satisfied ?

Variant DEMA Beast 29 elektrobicykel, metal blue/black

For the money, the best price-to-equipment ratio on the market. No problem. If someone wants a full-fledged one with decent components, there's nothing to hesitate about. You won't get one for that price even at the bazaars
