unnecessary, and you can use the tuning if you have an additional lighting system powered by the battery. The tuning makes the final speed void, that means the terminal velocity is only limited by the power of the drive and the muscular strength invested.

Safety instructions, product liability and exclusion of liability By using the bikespeed-RS on your pedelec, a relevant safety feature (the speed-dependent limitation of the motor power) is overridden. You must assume that your pedelec is not suitable for this and e.g., frame, brakes, chassis, tires, etc.

Bikespeed or the manufacturer of your pedelec cannot guarantee that brakes, frame, chassis, tires, etc. are designed for the use of the tuning part. Before use, the more highly stressed components of the pedelec (e.g., frame, brakes, tires, bearings, and suspension, etc.) must be tuned by the manufacturer or tested and approved by a suitable testing Centre (e.g.,...
Description of functions The bikespeed-RS removes the limit at 25 km/h of your pedelec. All other features and functions of your bike remain as usual. This also includes the protective measures installed by the manufacturer (e.g., short circuit, overcurrent, power, torque, temperature, etc.), except for the safety device for limiting the maximum speed.

Repeat the procedure, if necessary, to obtain the desired setting. If you have a bikespeed-RSc you use the combination you chose beforehand. (see page 13, paragraph Description of the custom-variant“) Furthermore, please note that you must switch the stages to enter the combination.

Level 1 will only switch to "off" in this way. If successful, the speedometer display changes 3 times between the software version of the bikespeed-RS and 0 km/h. Now the tuning is in service mode and maintenance as well as software updating can be executed.
Page 12
Please activate the service-mode only for updates on your pedelec! A switched off bikespeed-RS cannot be switched on with the combination for service-mode! After activating the service mode, we recommend switching off the bike without moving it again.

During installation, ensure that the ergonomic principle and functionality of the pedelec are not changed or impaired. The protection class of the bikespeed-RS is IP64. The bikespeed-RS does not require a separate power source. It is supplied with energy from the battery of the pedelec in which the tuning is installed.

If you still have questions, please feel free to contact us at any time. The bikespeed-RS is connected at the top of the cable outlet to the display and stowed away in the frame. A further cable must be routed through the frame down to the motor.

Loosen the lower mounting screw of the battery with a size 4 Allen key and remove the lower cover. Below the cover you will find the connector to the battery. Disconnect it by turning the bayonet lock counterclockwise and then pulling the plug downward. page 18...
Page 19
Loosen the upper fastening screw of the battery. (also with a size 4 Allen key) Pull the battery downwards out of the frame. Then loosen the two screws of the cable cover behind the battery with a Torx T15. Pull the cover out downwards. Note: The photo is rotated by 90°...

Locate the connector to the speed sensor. This is black, round and has a diameter of approx. 5mm. If you cannot find the connector, you can also follow the cable of the speed sensor at the cable inlet on the rear wheel and carefully pull or wiggle it.
Page 21
The connector to the speed sensor is needed at the front of the motor. (see first photo step 5) If this is not the case, you can carefully (!) try to pull the cable forward. If this is not possible, the motor must be loosened or removed.
Page 22
Plug these connectors to the counterparts on the bikespeed-RS. The two longer cables on the bikespeed-RS must be routed through the frame down to the motor. You can see the cable routing by the arrows. A cable puller is required for this step. This is pushed into the frame best from below the motor.
Page 23
Tie the two connectors of the bikespeed-RS to the cable puller and carefully pull it through the frame to the motor. On bikes without rear suspension, the cable routing may be different. Due to the seat post in the frame, the suggested cable path might not be possible.
Page 24
Stow the bikespeed-RS in the frame. You will find sufficient space for this in the direction shown in the photo. Mount the display by snapping it back into the frame at the bottom side, then fold it inside and secure it with the screw.
Page 25
Install the cable cover behind the battery removed in step 4. The cover has a key that must be snapped into the corresponding guide in the battery slot. Make sure to tuck all cables neatly behind the cover during assembly. It might be necessary to turn the slightly thicker Y-connection of the battery cable to the motor and charging socket in a fitting way, so that the cover can be closed neatly.

Hint for disposal Electric and electronic devices that have become waste are called old devices. Owners of such old devices must bring these to recycling facilities, where these are handled and recorded separately from urban solid waste. Old devices must not end up in the household refuse. In fact, they must be collected in special collecting and recycling systems.
