sIMPLEk - E-Bike Tuning Modules & Dongles as ready-made products or inexpensive kits

sIMPLEk

Under the name sIMPLEk, various tuning modules and dongles ("sticks") are offered that are unusual in some respects. First of all, it has to be said that the original sIMPLEk tuning tools were delivered in the form of kits for self-assembly. Since a soldering iron had to be used for the assembly, a little tinkering was required, but these tuning solutions were (or are) very reasonably priced. In the meantime, however, both the sIMPLEk modules and the dongles are available in somewhat more expensive "Pro versions" as ready-made products. You no longer need to assemble these yourself; you can attach them directly to the e-bike.

With both the permanently installed sIMPLEk modules and the plug-in sIMPLEk dongles, the 25 km/h speed limit can be completely waived. The tools are available for e-bikes of various brands, e.g. for Bosch, Yamaha, etc. By the way, the sIMPLEk stick was the first tuning dongle where the correct speed could still be read on the display!

The sIMPLEk stick can be activated / deactivated at any time by simply plugging in or removing the stick after installing the appropriate cable set. The sIMPLEk module, on the other hand, is installed in the engine housing and can be activated by means of certain key sequences when the bike is started up.

With both tuning tools (module and stick), the current speed is correctly displayed, but via the second digit of the display and the decimal place - a display of 13.5 km/h would then correspond to 35 km/h in reality, etc.

A real highlight is the sIMPLEk ECOplus Stick - this is an innovative tuning tool that has never existed in this form before. The ECOplus Stick does NOT increase the maximum motor-assisted speed, but extends the range of the e-bike by up to 20 percent! This works by gradually reducing the motor assistance at a constant speed. All sIMPLEk products are Made in Germany.

Three different sIMPLEk solutions

1) sIMPLEk kit

We have the sIMPLEk tuning kit for Bosch e-bike drives (Bosch Gen1, Gen2, Gen3 & Gen4), Impulse (kit with plug coupling, kit without plug coupling), Yamaha, and for Bafang Mid Drive in our range. They all completely remove the speed limit. Caution: Manual dexterity is required here.

2) sIMPLEk stick

The sIMPLEk Stick is the first dongle with correct speed on the e-bike display. It is available for Bosch drives (Bosch Gen1, Gen2, Gen3 & Gen4), as well as for Yamaha (PW, PW-SE, PW-X) and Brose motors. The solutions completely remove the speed limit.

3) sIMPLEk stick ECOplus

The sIMPLEk Stick ECOplus works differently: This tool maximises the range by slowly reducing the motor assistance - while maintaining the same speed. This leads to a maximisation of the range of up to 20%. The speed limit is not shifted in this process. The ECOplus dongle is available for Bosch drives (Bosch Gen1, Gen2, Gen3 & Gen4), as well as for Yamaha (PW, PW-SE, PW-X) and Brose motors.

sIMPLEk Tuning Tools as ready-made products!

sIMPLEk Stick Pro - The sIMPLEk dongle as a finished product

If you don't feel like assembling the sIMPLEk dongle yourself, we recommend the new Pro version. Here, the dongle is delivered completely assembled so that you can connect it directly to the e-bike. Apart from that, the Pro version has all the advantages that you already knew from the original sIMPLEk stick: The speed limit is completely removed and the installation is very simple. The actual speed remains readable, albeit via the second digit and the decimal place of the speed display. As it is a dongle with USB connection, the tuning hardware can be removed within seconds.

Available for the following e-bike drives: Bosch (Bosch Gen1, Gen2, Gen3 & Gen4), Yamaha (PW, PW-SE, PW-X, GIANT SyncDrive), Brose.

sIMPLEk Pro - The sIMPLEk module as a finished product

The popular sIMPLEk tuning module is now also available as a finished product - so you don't have to assemble the "Pro" version yourself before connecting the module to the engine. Otherwise, everything remains the same as with the original sIMPLEk module: The speed limit is completely removed, and after the simple installation, the module is no longer visible from the outside. The real speed remains readable, albeit via the second digit and the decimal place of the speed display.

Available for the following e-bike drives: Bosch (Bosch Gen1, Gen2, Gen3 & Gen4), Bafang, Yamaha (PW, PW-SE, PW-X, GIANT SyncDrive), Brose, Impulse (2.0, EVO, EVO RS) and Shimano.

The sIMPLEk Pro for Bosch Smart System 2022 (BES3) is new. A special version was released in the "Stealth" version. In this version, the maximum speed was limited to 37.5 km/h - this has the advantage that the probability of error messages is extremely low.
