Changes & Improvements New Controller: The BOOSTER PLUS was designed around the new controller, which has an updated control unit that allows for the Booster to accelerate smoother and in a progressive manner and to break stronger and in a shorter distance. So, when the accelerator is pushed, no matter if it is pushed all the way, the acceleration will go slowly to the maximum speed, not sudden as the normal Booster. The maximum speed is still 30 km/h, the torque still 15 Nm. With a design modification, the new controller support solves the wire abrasion issue and allows for the controller to be easily mounted. New Display: The BOOSTER PLUS comes with a new type of display. The aesthetics and the software are updated. The display features a new colored appearance and the software allows the battery level displayed to be more accurate. Also, the new display allows for the speed and cruise control settings to be easily set, showing exactly what you are choosing when setting them. (instructions enclosed). New Rear Wheel: The rear wheel of the BOOSTER PLUS is now more flexible, offering a better adherence and a smoother ride. It is airless but has multiple layers of rubber that allow for the wheel to be softer and stronger. New Charging Port: The BOOSTER PLUS comes with a new charger and an improved charging port, that is not only waterproof but also allows the charger to be inserted in a simpler and safer method, thus protecting the charging pins. Side and Rear Reflectors: The BOOSTER PLUS features 4 side reflectors, 2 on each side, so it can be safer to use and easier to spot in traffic. Thicker Platform: The platform becomes thicker in order to accommodate the side reflectors and to allow the battery removal to be easier. New Motor Cable Tie: The motor cables have a new binding system so that it looks better and also protects the cables from being damaged.
