With French and European market exclusivity, O2feel designs, develops and creates its own batteries in collaboration with its long-term partner Shimano. A technical choice to adapt our batteries to Shimano technology means we can offer you a balanced, intelligent bike.

Why do we develop

our batteries ?

Having control of our product’s technology allows us to remain unrestricted and innovative when it comes to our bike designs: sleek and discreet integration in the frame or saddle tube.

There is also the option of choosing the battery’s power and its weight depending on how the bike is used: leaving on an adventure and want long battery life? Do you have a lighter and compact folding bike? Do you want resistance for heavy loads?

Our teams of electrotechnicians can work directly on your battery in our workshops.

Finally, when your battery comes to the end of its life (at around 80,000 km) it will be processed as we are committed to a recycling and reconditioning network.

O2feel is committed to product durability and safety, and offers a 4-year warranty on its batteries.

of our batteries

Our batteries come with a smart BMS (Battery Management System) that controls the temperature, regulates the charge, discharge and cell balance in order to maintain performance and lifespan.

Originating from the car industry with the very latest format 21700 lithium cell that channels more energy than the previous generation, and a new “honeycomb” installation layout (3D) ensuring a level of reliability never achieved before. With its unique cellular and electronic features, this system has exceptional battery life.

Yes, but you won’t have any assistance. If you use a Di2 system, you can even change gears for a while as this uses less energy. Finally, remember to check your level when you get home at night or in the morning when you arrive at work for example, to pre-empt and avoid running out.

Yes. The assistance stops however there is enough energy remaining (emergency) for the screen to work, as well as the bike lights and Di2 gear changer (depending on the model).

Unfortunately not, at present there is no motor that is capable of recharging a battery by pedalling.
