The US manufacturer Specialized is well known in the e-bike industry for innovation, performance, and outstanding quality of build. It does not come as a surprise to see many ebike manufacturers following their footprint. Specialized equip their ebike fleet with the Brose engines but with a completely redesigned software which deliver a smoother support behaviour and an extremely natural driving experience. Another appealing feature of these engines is the decoupling of the crankshaft and the motor shaft. As a result, there is no pedalling resistance when you ride faster than the maximum supported 25 km/h (without tuning).
There are now several generations of the Specialized engines which have been continuously optimized. The company's most important engines at the moment include the Specialized 1.2 E (50 Nm), which has been optimized for particularly low energy consumption, the more powerful Specialized 1.3 (90 Nm), and the Specialized 2.1 (90 Nm) which is extremely light and has been tailored for e-mountain bikes with a pedalling power of up to 410% for climbing steep hills. The Brose Drive S Mag engines serves as the basis, but it was also equipped with its own software. All Specialized Turbo Levo FSR models have been equipped with this engines since model year 2019.
Specialized Tuning kits that connects into the TCU
At Ebikes Parts and Accessories we have in store a wide range of tuning including the most advanced Specialized tuning on the market. In our Specialized Tuning collection you will find the most advanced and easiest to install tuning on the market so let me introduce them to you one by one. In our personal opinion the SpeedFun Ribelle here really stands out since it connects directly on the TCU and installation does not take more than 1 minute. Furthermore, it retains the accuracy of the speedometer and the distance travelled and thus there is no need to use an external phone app to monitor the correct travelled speed and distance. The SpeedFun Ribelle Specialized is compatible with the Turbo 2.1 and Turbo Full Power System 2.2. It is not compatible with the 1.1 motors such as the SL models.
In comparison, the latest generation of the Levociraptor Gen 3 are compatible with all Specialized motors such as the 1.1, 2.1, and 2.2 (SL series). The Levocirpator Gen 3 comes with Bluetooth connectivity (BT) and an extra app (BLEvo App) that allows you to monitor via you phone the correct travelled speed and distance. Furthermore, the BLEvo app offers several appealing applications such as the 5 options to select speed, barometer, thermometer, crash detection to mention a few.
