Granville, one of the pioneers of classic cycling, has been offering a wide range of electrically assisted bicycles for several years. These latest generation VAEs stand out not only for their elegant design and ingenious design but also for their manufacturing quality and very careful finishing.
Moreover, the stylistic touch that distinguishes Granville electric bikes has become a trademark of this Belgian company. The new Granville VAEs are instantly recognizable and each bike displays a strong identity.
Without further ado, here is our comparison of the best Granville electric bikes!
The main characteristics of Granville electric bikes
Since its creation in 1929, Granville has used all its know-how to produce bicycles at the cutting edge of technology. Several parameters guide technical choices in terms of design: reliability, comfort, ease of use, performance, etc.
From the fork to the derailleur, including the frame and the engine, the components of Granville bicycles are carefully selected in order to produce bicycles that are elegant, reliable, and efficient.
Note that the electrical systems of Granville electric bikes meet all European standards in force, in particular directive 92/61/EEC and FR EN 15194 standards.
Framework structure
Like all premium electric bike manufacturers, Granville is constantly working 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 does not have a top tube and makes it easier to step over. It is very practical when you have to get on or off the bike, carry a child in the back, wear a fitted suit or dress or simply when you lack flexibility!
The materials are chosen according to the design and behavior that the Belgian manufacturer wishes to give to its VAEs. The frames of the models evaluated in this Granville electric bike comparison are constructed from 6061 aluminum alloy. It is a material offering several advantages in terms of robustness, lightness, responsiveness and comfort.
For the engineers and designers of the Belgian brand, the challenge was not only to optimize the shapes and volumes, but also to integrate the elements of the drive system. Thus, it was necessary to find the best design to integrate the electric motor, the battery, and the transmission system in such a way as to affect neither the robustness of the structure nor the stylistic code which has always distinguished bikes signed Granville.
The use of suitable manufacturing processes (hydroforming, heat treatments, extruding, etc.) made it possible to stiffen the structure while softening certain parts of the frame.
For models equipped with a removable Bosch PowerTube battery, special work has been done to integrate the battery into the downtube in the most optimal way. A careful design including an optimized cutout has made it possible to provide great strength and rigidity to the diagonal tube.
Electric motors
For the design of the drive system of its electric bikes, Granville called on two major renowned manufacturers: Bosch and Promovec.
The German equipment manufacturer Bosch, which no longer needs to be introduced, has great expertise in the field of mobility in general and that of electric micro-mobility in particular. Moreover, it positions itself as a leader in electric motor systems and electronic management solutions for electrically assisted bicycles.
On the models covered in our Granville electric bike review, we find three ranges of original Bosch 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 provides very pleasant handling. The three Bosch e-bike motors are very quiet and are characterized by 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 comparison of Granville electric bikes, has earned them several international awards, including the prestigious “Red Dot Award”.
The range of engines 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 engine has a compact design. It delivers a power of 250 W and a torque of 70 Nm, i.e. performance similar to that of the Bosch Performance Line motor. Like the other motors fitted to Granville electric bikes, the original Promovec motor is integrated into the crankset.
Granville electric bike batteries
The models tested in this Granville electric bike review benefit from some of the most modern Lithium-ion batteries on the market. These are developed exclusively to adapt to 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 luggage rack of the bicycle.
The PowerPack 400 version is installed on the Granville E-Urban Nexus and E-Premium 40 models. Integrated into the frame, it delivers a quantity of energy of approximately 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 a quantity of energy of approximately 500 Wh and offering a capacity of 13.4 Ah.
PowerTubes batteries have similar performance to PowerPacks batteries while being fully removable and slightly longer. These batteries can be mounted in a horizontal or vertical position depending on the architecture of the bike.
The Granville E-Terra electric bike model benefits from an intelligent combination of two PowerTubes 500 batteries (13.4 Ah), one of which is mounted on the frame and the other on the carrier. luggage. This dual battery system provides a quantity of energy of 1000 Wh and helps boost autonomy. Charge and discharge cycles are managed by an intelligent electronic module (GOB). This provides better protection against overheating, undervoltage, overloading, and short circuits.
For the battery of the E-Smooth 50 model, Granville once again turned to the Danish Promovec. This is a high-performance Li-ion battery with a capacity of 11.6 Ah developed in partnership with Panasonic.
The mechanical elements 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.
