Motor core and rotor
The Gen 2 X1 PRO motors are now built with new tooling equipment and QC procedures.
The motor core and rotor are redesigned. Now capable of handling >12krpm>6kW peak reliably.
The hall sensor wire is upgraded with waterproof connectors, eliminating the last weak spot of the X1 PRO motor.
Controller and Display
There were some reliability and firmware issues with the Gen 1 controller, which has been resolved in the latest Gen 1 motor as well.
After a year of hard work and feedback from our early adopters, we're now confident with the Gen 2 36V-72V controller in terms of experience and reliability. It has been a long development process to develop a controller handling up to kW with such a small footprint.
We've been extensively testing and tuning the new controller with eMTB enthusiasts to ensure this new controller is up to the task. We are very confident that our customers will be very happy with the new controller with the new firmware.
As for the display, it is also upgraded internally with the new 36-72V controller batch, ensuring reliability.
Mobile App
A new mobile app will be released in February 2020 on both iOS and Android platforms.
Our first trial of a mobile app (Released last year) was very complicated, and many of our previous customers are finding it difficult to configure the motor.
With the new app, we have a redesigned dashboard that is fully customizable, a map that supports .gpx files and offline maps, a fully functional data logger, and a much more simplified user experience.
Now the settings are much more straightforward and we have also included recommended default settings and tutorials to help you get through the setting process.
The fully customizable app means that you can have a bike that is truly personalized to your riding style and preference.
Components Upgrade
There are multiple component upgrades apart from the controller and motor.
The gearbox is now more refined with the new gear machining profile, and the gearbox noise is reduced by 50% as a result.
The electronics and sensors are now built in so there is no external part that is easy to be damaged.
The freewheel is redesigned as well. There is an increase in teeth number such that the engagement when pedaling is much faster and more direct.
The sprocket at the output shaft is now machined with hardened steel instead of stainless steel which handles 5kW or more extreme power.
Torque Sensor, Bottom Bracket & Crankset
The crank arms are upgraded with CNC aluminum lightweight crank arms.
Meanwhile, the torque sensor is now equipped such that both the torque and cadence signal are collected and processed by the controller to provide a natural feeling of pedal assist.
The torque sensor and controller firmware are tested extensively in the trails and we are proud to achieve comparable response and feel of the Euro-spec (e.g. Brose and Bosch etc.) eMTB in the low power legal mode.
