This chapter explains how to prepare your Ruffian for the ride. Inflate the tires first. The air pressure volume is described in chapter 3.1. Your Ruffian is supplied as a part assembly and as a full assembly. In the latter case, you can skip items 2.1. and 2.2.
COMMISSIONING 2.1. HANDLEBAR ALIGNMENT The stem is a significant safety component. When tightening the bolts, ensure that you use the torque as defined in the torque table under 9.3. Otherwise, there is a hazard of accident! » Lift the vehicle by the front frame, so that it no longer touches the ground.
COMMISSIONING » Place the crank in a horizontal position, the right pedal oriented towards the front wheel. » Tighten the pedal with an SW 8 Allen key at 30 - 35 Newton meter. 2.3. SETTING THE SADDLE DISTANCE The correct saddle distance is achieved when you can place your football on the pedal with your leg in extended position.
COMMISSIONING Do not pull the saddle support from the seat tube if you want to change the saddle height. The front part must lie flush with the upper tube. If you pull out the saddle support, both the support or the upper end of the seat tube may break.
COMMISSIONING 2.6. ADJUSTING SUPPORT LEVEL For the adjustment of the support level, press the „+“ button on the control unit until the required support level is shown on the display. To lower it, press the „–“ button. 2.7. SWITCHING ON/OFF THE LAMP By pressing the light button, the LED head- lamp and rear light are switched on and off.
BEFORE EACH RIDE BEFORE EACH RIDE 3.1. CHECK TIRES Air pressure: The allowed pressure range of the Cruzo Classic 76-559 is between 1 and 2.5 bar. The following applies: The higher your weight, the higher the air pressure to be used. If you are not a light-weight person, set the pressure of your rear tire at 2.5 bar.
BEFORE EACH RIDE » The brake discs must be oil-free. Any oil on the brake discs is removed with alcohol. Do not use a conventional brake disc cleaning solution! The pressure point is the lever position of the travel at which the brake is engaged.
BEFORE EACH RIDE 3.6. CHECKING THE SCREW CONNECTIONS Before each ride, check the firm screw connections for » Quick release of the front wheel » Screw axis of the rear wheel Also check that the following parts do not rotate: »...
OPERATION BEFORE EACH RIDE 4.1. NUVINCI HUB GEAR The NuVinci gear system allows the stepless adjustment of the transmission via a twist grip. Changing gear during the ride » For starting or riding up a hill, change to a low gear ratio: Turn the Nfinity Controller twist grip to the "Mountain"...
OPERATION 4.2. DRIVE UNITS 4.2.1. BELT DRIVE UNITS At delivery, the belt is optimally tensioned and is not to be re-tensioned, nei- ther after the prolonged use of the drive. When mounted correctly, a high load can be placed on the belt in pulling direction. The carbon fibers embedded in the belt are very flexible, but react very sensitively to knicking twisting...
4.3. BRAKE SYSTEM Your Ruffian is equipped with hydraulic brake discs for a fast and safe stop- ping action. Use both brakes simultaneously for an optimal and safe braking. The left brake lever has an effect on the front wheel brake, the right brake lever has an effect on the rear wheel brake.
ERGONOMIC SETTING 4.4. SIDE STAND When manipulating your side stand, observe the following: Riding with unfolded side stand may lead to falling. Moving the Pedelec backwards with an unfolded side stand may lead to the clamping of the stand onto the crank. ->...
MAINTENANCE 5.2. BRAKE LEVER You can adjust the brake lever position on the handlebar, along with the brake lever angle and lever width. 5.2.1. ADJUSTING BRAKE LEVER POSITION For a firm holding onto the handlebars when braking, take the brake lever by your index and middle finger.
MAINTENANCE 5.2.3. ADJUSTING BRAKE LEVER DISTANCE The brake lever distance setting should allow to operate the brake lever by the first pha- lanxes of both fingers positioned on the lever. The lever width is adjusted with a T25 p-han- dle Torx compatible wrench. For this purpose, adjust the screw at the marked position 1.
MAINTENANCE 6.1. WEAR PARTS LIST The following parts of your Pedelec are subject to wear according to their use. This wear is not covered by the warranty. » Battery » Tires and tubes » Brake pads, brake discs » Chain, chain ring and sprocket »...
MAINTENANCE » Check headlamp inclination » Check brake pad wear condition (first time after 621 miles (1,000 km)) Every 1242 miles (2,000 km) (or once a year) » Check brake disc wear condition » Check tightening torques of brake levers, saddle, saddle support, stem, han- dlebar »...
MAINTENANCE Environmental temperature at storage Battery life is reduced when the bike is stalled at temperatures exceeding 30 °C or in the direct sunlight. Storage at temperatures between 0 and 20 °C increases the battery life. Charging status during storage The highest battery life is achieved when the battery is stored with a charging status of approx.

MAINTENANCE » Open the quick release by turning over the handle. » Loosen the nut a few turns at the other end of the quick release. The front wheel is now slid out from the dropout of the fork. » Move the transportation lock between the brake pads.
MAINTENANCE 6.6.2. DISMOUNTING THE REAR WHEEL » Change gear to a position allowing the easy access to the cable pull end on the Nfinity hub interface. » Remove the cable pull ends provided with a snapper or catch from the Nfinity hub inter- face following steps 1, 2 and 3.
MAINTENANCE 6.6.3. CHANGING TIRES/TUBE » Unscrew the valve cap from the valve. » Release the air completely by pressing the valve pin halfway the valve. » Remove the tire at one side of the wheel rim with the aid of a tire lever. If required, use a rinsing agent and water for an easy lifting of the tire.
MAINTENANCE With too low an initial tension of the quick release, the wheel can come off during the ride. A hazard of accident exists! -> Always tighten the quick release firmly so that when lifting up the tension lever, by its force it leaves an imprint on the palm of your hand.
