Preface Keep in mind that every bicycle type is built for a specific intended use. Be sure to use your bi- cycle only according to its intended use, as it may otherwise not withstand the stress and would fail and cause an accident with unforeseeable consequences! 1.
regulations. • Adjust your handling on wet or slippery roads; ride more slowly and brake carefully and in good time as you will require a much greater braking distance. • Adopt a speed that reflects the terrain as well as your riding ability. • Do not listen to music through headphones when cycling. • Do not cycle when using a mobile phone.
Quick Start Guide: 8 steps to getting on the road (Before the first ride) CAUTION: E-BIKE OWNERS: Do not use the battery for the first time until it has been fully charged at least once or you may decrease its perform¬ance (see instructions below). 1. Unpack the bike and check the contents Carefully remove your bicycle and all other items from the box. You may find it easier to open the side of the box and roll the bike out.
correct handlebar height. Check to make sure the brake levers, gear shifts, displayer, bar ends and other parts attached to the handlebars are positioned comfortably. These can all be adjust- ed using one of the included Allen keys. 5. Adjust the seat Using an Allen key, loosen the nut on the side of the seat post clamp.

III-2.2: Operating the quick-release device WARNING: • All quick-release devices must be tightened securely before you set off. Check this before every journey. • If you leave your bike unattended, check that all quick-release devices are correctly secured before setting off again. • When closing the quick-release lever to lock it, it must be necessary to apply a force that causes you to make a first with your hand as otherwise the quick- release device could...
III-2.4: Adjusting the saddle angle • Your bike saddle should be as close as possible to horizontal. • You can make use of longer bike rides to find out what your most comfortable seat position is. If you want to tilt the saddle, try tilting it very slightly forwards.
Adjust the handlebar tilt as follows: • Undo the clamping screw by turning it anticlockwise through two or three revolutions using an Allen key. • If you own a model that is also equipped with detents, continue turning the c lamping screw anticlockwise to disengage the detents. •...
WARNING: Checking the headset If you do not adjust the headset properly or tighten it too tightly, this could cause bre-ak- ages. This should therefore always be carried out by a professional bike workshop. If you ride with the headset loose, Unis could damage the bearing shells or fork. VI.
ticularly high level of stress due to unevenness of the riding surface and the weight of the rider. The wheels are carefully checked and trued prior to delivery. However, the spokes may settle when you ride the first kilometer on your bike. •...
Always replace the tyre with a tyre of the same type, dimension and profile as otherwise the ride characteristics may be adversely affected. This can lead to accidents. CAUTION: Tyres are wear parts. Check the tread depth, tyre pressure and condition of the tyre side- walls regularly.
X-1. Important information and precautionary measures WARNING: Have maintenance work on t\e brakes carried out by a professional bike workshop. Do not allow fluids containing oils to come into contact with the brake pads, brake con- tact surfaces on the rim, brake blocks or brake disc as this could otherwise impair the effectiveness of the brake. Brake blocks and brake pads are wear parts.
X-3. Disc brakes With this brake type, the brake discs are on the hub and the brake caliper is on the frame or fork. WARNING: Have your disc brakes adjusted by a specialist cycle shop. If this is done incorrectly, an accident may occur. Once the brakes have been adjusted, always perform a brake test by pushing the bike quickly forwards and operating the brake lever.
Page 19
WARNING: Once the brakes have been adjusted, always perform a brake test by pushing the bike quickly fbrwards and operating the brake lever. You should only use your bike if you can safely stop it using the brakes. Check regularly, also before each journey, that the lines and connections are tight. If lines and connections are not tight, brake fluid may escape from the brake system. The brake may not work properly as a result.
X-3.4: Fitting/removing the wheel • When removing the wheel, we recommend you use a brake block spacer. This prevents the piston from being pushed out if the brake lever is operated once the wheel has been re- moved. This also prevents air bubbles in the expansion vessel from entering the system. •...
XI-2. Shifting lever XI-2.1: Standard shifting lever Both levers a and b always revert to the initial position after they are pressed. The crank must always be turned when a lever is pressed. Operating the front derailleur shifting lever Shifting from a small to a large chain ring Press lever a once to move the chain from a small to a larger chain ring.
If the chain is on the large chain ring and the large sprocket, the chain will rub the front derailleur producing a characteristic noise. When this happens, press lever b lightly to the point where it clicks, this causes the front derailleur to move slightly towards the smaller chain ring, thereby eliminating the noise.
NOTE: If the chain is in the position shown, it could rub against the chain rings or the front derailleur and make a noise. If this is the case, you can shift the chain onto the sec- ond or next largest sprocket. XI-3.2: Cleaning •...
XIII. Electric system XIII-1. E-bike fundamental legal principles The fundamental idea behind the E-bike is not only to be able to cover greater distances more quickly, but also do this comfortably. You can choose to relax and let the bike do the work, exert yourself more physically, or simply to get from A to Bas fast as possible.

Infor- mation about the battery and its charge state is provid- ed based on the number of LEDs that light up and the way in which they light up.
XVII. Charger Read the two stickers on the charger before using it for thefirsttime. WARNING: Do not use other chargers. Only charge the battery using the charger provided, NOTE: If used incorrectly, the device may be damaged or inflict injuries. •...
XVIII. Care and maintenance of the bike XVIII-1. Care WARNING: Do not allow care products or oils to come into contact with brake pads, brake discs and the rim's brake contact surfaces. This could reduce the effectiveness of the brake. NOTE: Do not use a powerful water jet or high-pressure cleaner.
XVIII-3. Tires Due to their function, bike tires are subject to wear. TTiis depends on how the bike is used and the rider can influence this significantly. Do not brake so sharply that the wheels lock. • Check the tire pressure regularly. The maximum permissible tire pressure, and normally also the minimum permissible pressure, can be found on the tire wall.
XVIII-10. Handlebar tapes and handle grips Handlebar tapes and handle grips are subject to function related wear and therefore may need to be replaced. • Check regularly that the handles are securely seated. XVIII-11. Hydraulic oils and lubricants The effectiveness of hydraulic oils and lubricants decreases over time. If lubricants are not replaced, this increases the wear of the relevant components and bearings.
