Product question
Tern Orox S12 27.5 electric bike
Level and quality of equipmenthelp
Serious sports equipment for intense and regular off-road driving, where you can 100% rely on sufficient performance and component installation.
Aluminium frame
Lighter, relatively durable and stiff material that is affordable. The most widespread material for the production of bicycle frames.
27.5” wheels
Universal size for a wide range of bicycles. The advantage is better cross-country ability, higher traction and comfort, and still good dexterity. Slightly heavier.
Hydraulic disc brakes
Reliable in all conditions, better modulation of the braking effect with the use of less force on the lever. Heavier weight, more demanding service.
Rigid fork
You will appreciate the lighter weight and stiffness, especially when riding on the road or bike path. Minimal service.

Our editorial video related to this product
warning
Due to long-term issues with the supply of components, some manufacturers exceptionally approach changes of installed components contrary to the specification without letting us know. Unfortunately, it is not in our power to go through each bike and verify the differences between the manufacturer's stated components and its actual equipment. Alternative parts should meet the same standards as the original. We apologise for any discrepancies.

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:
- 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 pickup 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 tires 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.
