Battery on frame or back pack ?

All major brands that sell complete bikes with Bosch or Yamaha  mount the battery on the frame, because it is simpler to implement and allows to propose models "all public"


But for mountain bike, use the battery in a backpack remains in our opinion a much better option in terms of performance.


This will allow you to gain weight on the bike, that usually and place relatively high on the bike, and thus to have a bike more fun to ride.


Our batteries are very light, for example, the model 8.7 a/h is 1.6kg.


That the weight of 1.5l of water, you can simulate this weight by putting 1.5l of water in your bag.


We use and resale classic EVOC bags (CC range) and bags of the same brand with integrated CE back protector (protector range) always better in case of fall.

Equipped with a ANDERSON connector designed to plug of in case of a fall.


We usually disconnect the system for hard downhill parts. (see video)


If you would like a battery on the bike:

Less convinced by this type of fixing, we still developed a quick and aesthetic solution for this type of fixation to be able to attach to very compact batteries type 8.7Ah on frames with little space.


This support works like a bicycle bottel cage but beside a battery, so you can use the door canister, as in the photos below.

We also offer for sale, batteries type bottle, which fixes in places and place your canister door this type of mounting requires a lot of room in the frame, so check that this type of battery is compatible with your frame and with the operation of your rear suspension.


Our battery models are very compact (see table).


In some cases, it can take place above the lower tube or other according to the architecture of your frame.


It is always possible to fix the batteries in a bag that you can make and adapted to the constraints of your frame.


If this type of editing interests you, you can make a small cardboard model to the side of the battery to see if it can fit, and what it can give once positioned.

Warning !


When fix the battery to the frame or you plan to do, check if nothing will touch when the suspensions will be full compressed.


If you have any doubt, deflate your suspensions to check if the available space is actually enought to add a battery.
