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.

The cable that connects the battery to the bike, from the bag, to the head tube (In red on the photo).

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 / 11.6ah 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, batteries type bottle wuth hard plastic case, which fixes in places and place your bottel cage, this type of mounting requires a lot of space in the frame, so check that this type of battery is compatible with your frame and with the operation of your rear suspension.

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 fixation interests you, you can do a small cardboard model of the battery to see if it can fit.

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.

Also note, a bicycle battery is made up of different cells, which are small batteries that are welded together, so it is important that the pressure exerted on the battery is well distributed if it is attached to the frame.

It is therefore strongly advised not to want to fix the battery with zipcollard or straps to the frame without a rigid support which distributes the constraints such as our aluminum support, this would risk maybe bend the electric mountain bike battery work at the welds and damaging it .
