Why this e-bike?

  • The ALUXX SL aluminium frame with carbon upper rocker and trunnion mount offers a full 160 mm stroke. Maestro's fully active and powerful responsive suspension is perfectly attentive to the cushioning of unevenness, while not restricting uphill free riding. The front air fork provides 170mm stroke, 10 mm more than the rear structure.
  • The powerful Giant SyncDrive Pro Yamaha Center Engine (80Nm) offers five driving modes with up to 360% support. The energy comes from the innovative Giant EnergyPak Smart 500Wh lithium battery, which is fully integrated and farther down from the bottom tube. When you use the batteries, the 6A quick charger will charge the battery to 60% capacity in just 90 minutes. The wheel frame should be used to secure the battery, allowing you an additional 250Wh for even greater range (this EnergyPak Plus battery will also be available as an optional accessory).
  • The RideControl ONE control unit features powerful ergonomics for switching driving modes, battery status LEDs and a selected driving mode, as well as a walking assist button, assisting the motor to guide the wheel after walking. With Bluetooth, you can use your bike to pair with Giant RideControl, sharing the download to your smartphone (for Android and iOS) - this app will help you receive a host of other useful features such as precise battery status, support in all driving modes according to your preferences, driving logs and fitness features including an analysis of your performance.
  • All Reign E + models are fitted with wide 'plus' rims, which are fitted with tubeless tyres with a width of 2.6" - the ride will be pleasant, fun, safe and less risky. And you cannot miss the telescopic seatpost with handlebar controls.

Giant SyncDrive Sport


Giant SyncDrive 250 W central electric motors are the result of the close cooperation of the Giant with the leader in electric motors - Yamaha, guaranteeing their high quality and reliability.

Despite the compact size, they deliver a high torque of up to 80 Nm, which shows just as soon as you start your ride. Their immediate response is also important – the motor starts running as soon as you begin to pedal. This quick response will not only help you when accelerating, but also truly comes in handy in many steep climbs, when you rely on the e-bike to "pull" you up.

The SyncDrive motors produce proportional and linear support, and their operation is predictable, smooth and quiet, simply a natural boost to your own energy.
