your e-bike excellent rideability. Despite these properties, under excessive overloading or impact, the 

carbon structure can be damaged – cracked.

        IMPORTANT NOTICE 

When used properly, composite frames have a higher fatigue life than metal frames. However, you 

need to check such a frame regularly, especially after any collision or accident. If you find damage 

such as cracks, do not continue to use the frame! Be aware when fitting components to the composite 

frame, especially when tightening the seat clamp bolts, rear suspension mechanism bolts and rear 

axle bolts. Observe the recommended torques!

Do not expose the carbon frame or any other component to high or extremely low temperatures, as 

this could lead to structural changes in the material and subsequent cracking. Damage to the carbon 

may not be visible, so we recommend replacing any carbon components that have been exposed to 

extreme temperatures or significant impact, even if the damage is not visible to the eye.

        NOTICE 

If you use a  mounting stand for e-bike maintenance, never mount the e-bike by the frame – 

compressing the frame can crack the composite material.

In the event of a  service that requires the use of special tools, we recommend that you contact 

a professional bike workshop.

SUSPENSION FORK

If you have a suspension fork on your e-bike, do the following:

SUSPENSION HARDNESS ADJUSTMENT

1. SPRING FORK

The unit for adjusting the hardness of the suspension fork is located at the top of the right fork leg. On 

a suspension fork that is equipped with a suspension lockout, the hardness adjustment unit is located 

on the left fork leg. Gradually turn clockwise to set a higher fork firmness, turning counter-clockwise 

decreases the fork hardness.

should rotate without any friction and play. If this is not the case even after adjustment with the help 

of cones and lock nuts, it is necessary to disassemble the hub, clean the sliding paths of the balls and 

the balls themselves, lubricate with a new suitable lubricant and reassemble and adjust the hub. If you 

do not have experience with hub disassembly, due to the complexity of such a task, we recommend 

you contact a professional bike service.

RIM

Before riding, check that the e-bike wheels are correctly centred and that the wheel rims are not 

damaged. Use or impact can cause grooves and cracks on the rim. Riding on a  damaged rim is 

dangerous – replace the damaged rim!

TYRE

Never ride on under-inflated or over-inflated tyres. Observe the recommended inflation values shown 

on the sidewalls of each tyre. Conversion of the pressure measurement units indicated on the tyres: 

100 kPa = 14.22 P.S.I. = 1 bar = 1 at

In case of a  puncture, always replace the damaged inner tube with a  new one with the same 

parameters – the dimensions are indicated on each inner tube or on the side walls of the tyre.

Before installing a new inner tube, inspect the tyre inside and out around the entire circumference, 

as well as the rim around the circumference, and remove any dirt or foreign objects that may have 

caused the defect to prevent damage to the new inner tube. If there is a crack or other damage to the 

tyre, it should be replaced immediately with a new tyre of the same specifications.

FRAME AND FRONT FORK

Regularly check the frame and fork of your e-bike for damage. Damage to the frame or fork (bending 

or breaking of tubes or welds) occurs mainly in crashes. Do not continue to use a damaged frame or 

fork in this way, you risk serious injury!

CARBON COMPOSITE FRAME

The carbon composite gives the frame high strength, low weight, vibration damping and thus gives
