Product questions
BULLS E-Stream EVO TR1 27.5 electric bike
Level and quality of equipmenthelp
Built for regular rides on unpaved and forest roads, with equipment with a good balance of durability, functionality and performance.
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.
Air fork
The best option in terms of weight and comfort. Provides more adjustment options (rebound, compression). Requires regular service - the service cycle is specified by the manufacturer.
Air shock
When buying a bicycle, it is necessary to set it to the required pressure according to the weight of the rider (specified by the manufacturer of the shock absorber, a shop assistant can also help you). Can provide several ride and suspension adjustment options. Requires regular check-up and is also more demanding to service. Compared to the spring one, it is significantly lighter.

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 packaged back into a box and shipped
- If you order a bike for in-person pick-up or home delivery, the bike will be waiting for you assembled and checked
- 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 seat post 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.

Byvam casto kriticky, ale po prvej jazde dostava Bulls 5 hviezdiciek. vazi 27kg, co nie je malo, ale je skvele ovladatelny, 26.feb. bolo blato, bahno, sneh aj lad - vsetko sme skvele zvladli. 925Wh + 90Nm = vydrz + sila slona (vlastne bujaka). v rezime AUTO nie je co riesit, v lubovolnom terene, sklone ci rychlosti. jazdim freeride na Santa Cruz, tak som mu nic neodpustil, ale nesklamal, ked mal, tak ma podrzal.
