Granville, one of the pioneers of the classic bike, has offered for several years a wide range of electric bikes. These latest-generation e-bikes stand out not only for their elegant design and ingenious construction but also for their manufacturing quality and very refined finish.
Moreover, the stylistic touch that distinguishes Granville electric bikes has become a trademark of this Belgian company. The new Granville e-bikes are recognizable among all, and each bike displays a strong identity.
Without further delay, here is our comparison of the best Granville electric bikes!
The main features of Granville electric bikes
Since its creation in 1929, Granville has used all its expertise to produce cutting-edge technology bikes. Several parameters guide technical choices in terms of design: reliability, comfort, ease of use, performance, etc.
From the fork to the derailleur, through the frame and the motor, the components of Granville bikes are carefully selected to produce bikes that are both elegant, reliable, and high-performing.
Note that the electrical systems of Granville electric bikes comply with all current European standards, including directive 92/61/EEC and standards FR EN 15194.
Frame structure
Like all premium electric bike manufacturers, Granville constantly works to improve the design, geometry, and kinematics of its frames.
On most models, it offers two frame versions: a standard version (straight frame) and an “Open” or “Easy Entry” version (open frame). The latter lacks a top tube and makes mounting easier. It proves very practical when you need to get on or off the electric bike, carry a child on the back, wear a fitted suit or a dress, or simply when you lack flexibility!
Materials are chosen based on the design and behavior that the Belgian manufacturer wants to give its electric bikes. The frames of the models evaluated in this Granville electric bike comparison are built from 6061 aluminum alloy. This material offers several advantages in terms of strength, lightness, responsiveness, and comfort.
For the brand’s Belgian engineers and designers, the challenge was not only to optimize shapes and volumes but also to integrate the elements of the drive system. Thus, the best design had to be found to integrate the electric motor, the battery, and the transmission system in a way that would not affect either the robustness of the structure or the stylistic code that has always distinguished Granville-signed bikes.
The use of adapted manufacturing processes (hydroforming, heat treatments, extrusion...) helped to stiffen the structure while softening certain parts of the frame.
For models equipped with a removable Bosch PowerTube battery, special work was done to integrate the battery in the most optimal way into the down tube. A careful design including an optimized cutout provided great strength and rigidity to the down tube.
The electric motors
For the design of the drive system of its electric bikes, Granville called on two renowned major manufacturers: Bosch and Promovec.
The German equipment manufacturer Bosch, well known, has great expertise in the field of mobility in general and electric micro-mobility in particular. Moreover, it positions itself as a leader in electric motorization systems and electronic management solutions for electric bikes.
On the models reviewed in our Granville electric bike review, there are three ranges of Bosch-origin brushless motors:
- The Bosch Active Line motor (250 W; 40 Nm), mounted on the Granville E-Premium 40.
- The Bosch Active Line Plus motor (250 W; 50 Nm), mounted on the Granville E-Urban Nexus.
- The Bosch Performance Line motor (250 W; 65 to 70 Nm), mounted on the Granville E-Terra and the Granville E-Integrated 20.
Each of the drive units is integrated into the crankset, which offers very pleasant handling. The three Bosch motors for electric bike are very quiet and stand out for their low pedaling resistance. They also feature a compact design and proportions perfectly suited to the original style of Granville bikes.
Moreover, this design, which we highlight in our Granville electric bike comparison, has earned them several international awards, including the prestigious “Red Dot Award”.
The range of motorization options offered for Granville electric bikes also includes a brushless motor supplied by the Danish manufacturer Promovec.
Mounted on the Granville E-Smooth 50 model, this latest generation motor features a compact design. It delivers a power of 250 W and a torque of 70 Nm, which are performances similar to those of the Bosch Performance Line motor. Like the other motors equipping Granville electric bikes, the original Promovec motor is integrated into the crankset.
The batteries of Granville electric bikes
The models tested in this Granville electric bike review feature some of the most modern Lithium-ion batteries on the market. These are developed exclusively to fit the characteristics of the drive systems supplied by Bosch and Promovec.
On models equipped with Bosch motors, there are two battery variants: Bosch PowerPacks batteries and Bosch PowerTubes batteries.
PowerPacks batteries are offered in 2 versions: PowerPack 400 and PowerPack 500. They are designed to be mounted on the frame or on the bike's luggage rack.
The PowerPack 400 version is installed on the Granville E-Urban Nexus and E-Premium 40 models. Integrated into the frame, it delivers an energy amount of about 400 Wh and offers a capacity of 11.6 Ah.
As for the Granville E-Integrated 20, it receives a Bosch PowerPack 500 battery delivering an energy amount of about 500 Wh and offering a capacity of 13.4 Ah.
PowerTubes batteries deliver performance similar to PowerPacks batteries while being fully removable and slightly longer. These batteries can be mounted in a horizontal or vertical position depending on the bike's architecture.
The Granville E-Terra electric bike model benefits from a smart combination of two PowerTubes 500 batteries (13.4 Ah), one mounted on the frame and the other on the luggage rack. This dual battery system provides an energy amount of 1000 Wh and allows boosting the range. The charge and discharge cycles are managed by an intelligent electronic module (GOB). This offers better protection against overheating, undervoltage, overcharging, and short circuits.
For the battery of the E-Smooth 50 model, Granville once again turned to the Danish company Promovec. It is a high-performance Li-ion battery with a capacity of 11.6 Ah developed in partnership with Panasonic.
The mechanical components of Granville electric bikes
The products evaluated in this Granville electric bike comparison stand out not only for their authentic design but also for the exceptional quality of their mechanical parts. For the transmission system of Granville electric bikes, there are 7 to 9-speed derailleurs supplied by Shimano.
The range offered by the Japanese equipment manufacturer includes two Altus derailleurs with 7 and 8 speeds, an Alivio derailleur with 9 speeds, an integrated Nexus derailleur with 7 speeds, and an XT derailleur with 9 speeds.
Altus derailleurs are entry-level models that are more suitable for occasional use. With better finishing, the Alivio derailleur is equipped with a bidirectional trigger, making it more pleasant to use. The integrated Nexus 7 derailleur stands out for its well-graded gear range, allowing easy finding of the right cadence.
More sophisticated, the XT derailleur (Deore) is the most complete transmission system offered on Granville bikes. Due to its well-thought-out design and robustness, it is suitable for various types of riding: hiking, trail, cross-country, etc. In fact, it is used on many competitive mountain bike models.
