How far can I expect to ride on a single battery charge?
The range for a single battery charge can vary greatly depending on conditions such as the combined weight of the rider and cargo; wind resistance; tyre pressure and tread profile; terrain and elevation changes; road or trail surface; outdoor temperature; maintenance of the E-Bike; and the condition of the battery.
The bar below gives an approximate range. Conditions are categorized as extreme, good and ideal. Extreme conditions typically occur when riding with a heavy load, strong headwinds or excessive climbs.
A 29-inch front wheel and 27.5-inch rear wheel work together to offer superior handling and agility on technical terrain. The updated frameset features new geometry with a shorter rear end and longer reach. New control units include RideControl Go, which is integrated into the top tube, and RideControl Ergo 3, attached to the handlebar near the grip. A new flip chip feature lets you adjust frame geometry for riding style and terrain.
This state-of-the-art aluminum material is made predominantly from 6011 alloy and delivers best-in-class strength-to-weight ratios. The frameset also features unique welding technologies for a high-performance ride quality.
This innovative system combines electric power with human power to produce a smart, natural and powerful E-bike riding experience. It’s an integrated group of technologies that includes our RideControl control unit, EnergyPak battery system and SyncDrive Pro motor.
The new motor is co-developed with Yamaha and optimized for the Reign E+ chassis and Maestro suspension. The compact motor is now lighter (2.7kg) with increased torque output (up to 85Nm) and significantly reduced noise levels.
New handlebar remote can be mounted on the left or right side for a clean cockpit layout depending on your preference. You also have the option to add a second control, giving you another three buttons. The buttons can be configured with the RideControl app to fully customize your controls.
Six smart sensors precisely measure the power being applied to the pedals so the motor can provide just the right amount of assistance to create a natural, powerful riding experience. This helps optimize energy efficiency for both the rider and the battery system.
RideControl Ergo wirelessly connects with the RideControl App so your smart phone can function as a display for ride data and system updates.
Our most advanced E-bike battery system is cleanly integrated within the downtube of the frame.
New top-tube integrated, multi-function on/off button can power on the E-bike quickly and easily. It can also change the motor settings.
Four strategically positioned pivot points and two linkages all work together to create a single floating pivot for the most active, efficient and independent suspension system on the trail.
Integrated Tubeless Wheel System and tire deliver improved efficiency, comfort and control in the most user-friendly and reliable system.
A flip chip lets you change the head tube and seat tube angles, along with the bottom bracket height, to fine-tune the handling. You can choose the low setting for faster, more open terrain, or the high setting for slower, tighter singletrack.
This range extender can boost total capacity by 250Wh. It has all the latest technologies combined with an up-to-date design that fits a select number of bikes. It has smart technology so it automatically turns on when your battery loses power, giving you peace of mind that you can reach your destination.
Available on premium Giant E-Bikes, RideControl Go features a multipurpose button integrated into the top tube. Colored LEDs allow you to switch power modes from the top tube and keep a clean handlebar setup. The lights also display battery level and support mode.
This updated control system features clean buttons that are integrated with the handlebar grips. You can install the three-button control on the left or right side, making it easy to switch power modes. You also have the option of adding a second control on the other side. Using the RideControl App, you can configure it to your own personal preferences.
SyncDrive Pro powered by Yamaha is designed for high-performance E-bike riding. Giant tuned the motor to make it more powerful, producing a performance-oriented riding style. The lightweight, compact SyncDrive Pro motor is used primarily on Giant’s high-performance models.
This all-new technology allows riders to quickly adjust the geometry and choose a rear wheel size (29-inch or 27.5-inch) for their riding style and terrain. It’s available on select Maestro-equipped mountain bikes. The adjustment affects head tube and seat tube angles, bottom bracket height, and rear-wheel size using eccentric flip chip hardware located on the upper rocker arm of the rear suspension.
