The Thru axle motor exists in two versions: the TC2540 1000W motor and the TC3080 2000W motor


the TC2540 is perfect to electrify your mountain bike with 12x142mm of axis. You can install it until 10 pinions on the motor.


The TC3080 is bigger and more powerful. It accepts 2000W of maximum power, but because its large you can only install 7 pinions in a spacing of 142mm and 10 pinions for 148mm.


We advise you the TC3080 for mountain bike equipped with the BOOST 12x148mm of for those who wants a 2000W configuration.


For 12x142mm we advise you the TC2540 

Vous pourrez visser votre disque de frein au standard 6 trous sur le moteur. Pour les vélos équipés de freins à patins, n'oubliez pas de commander une jante à bords surfacés comme la Mach1 260.

The torque ARM of the through axle motor is require. It's includes with the motor.

You can screw your brake disc with 6 holes on the motor. For bikes equipped with skide brake please don’t forget to command rim with surfaced borders like the Mach1 260.


The OZO 25A is available for both motors, whereas the 35A and 40A controller are only available for the TC3080 motor.

These controllers are pure technology. It integrates high quality electronic component issued of automotive world.

The dual sensored/sensorless sinusoidal cartography can adapt to oriented fields (FOC) will avoid breakdown frequently meet with competitor’s mountain bike.

This controller is the brain of your kit. It will allow you to do whatever you want with your electric bike.

You can drive your bike via the pedal sensor if you want an electric assistance by pedaling or via an accelerator (or both).

You can use board computer (cycle analyst) to set the motorization settings by yourself.

Totally evolutionary: Over time, you can add on your bike multiple functionalities: cycle analyst V2 or V3, 3 positions switch, speed regulator, ON/OFF switch, regeneration, cutout brake, pedal sensor, accelerator…


To drive your motor, you’ll require a pedal sensor or a handle accelerator. Or both in the same time. The pedal sensor (pedelec) allow an assistance while pedaling you pedal, the moror is engaged, you stop pedaling, the motor stop. If you are using the pedal sensor, don’t forget to take in supplement a 3 positions switch and/or a cycle analyst. And you can profit of multiple assistance mod

Please note that the accelerator is really useful pour hill starts and obstacles crossing.

The pedal sensor also call pedelec is a rotation sensor. You are required to pedal to get this assistance.

To be certain to choose the right pedal sensor for you bike, please see a video about this subject or read the manual at the bottom of this page.

Integrated pedal sensor: For chain set housing of squared axis having a minimum 4mm gap between the crank and the frame.

Pedal sensor with magnetic disk: For other bikes which don’t have a minimum gap to install an integrate sensor.


The accelerator can manually dose the power sent to the motor. It can be used alone or with the pedal sensor. We advise you for a mountain bike use. It exists in two versions:

  • Thumb throttle (installed left)

  • Half throttle (installed right)


You’ll have to supply your  thru axle wheel motor kit with a 36V or 48V battery. Every 36V or 48V OZO batteries are compatible with this motor.

The capacity choice is done in function of the wanted autonomy. For example, a 500Wh battery will offer you around 50km (31 mile) of autonomy without forcing the bike to 100km (62 mile) in function of your effort. A 1000Wh battery will offer you the double of autonomy.

The second criteria is to know where do you want to install your battery on your bike. For that

We are proposing you two versions of battery: Box battery and PVC battery.

Offer a protection against humidity, rain, impacts and dust and allow you to lock the battery.

Please verify the dimensions of the battery by going directly on the concerned product sheet.

They are lighter and less costing. But you’ll have to installer it in a backpack or in a cover to assure it protection. Using them in backpack is for electric mountain bike or with electric assistance. Because the bike is lighter so more manageable.


Accelerator : The accelerator will allow you to manually dose from 0 to 100% the motor power.

It can be used alone or in parallel with a pedal sensor.

We offer two types of accelerator: a semi-rotating handle or thumb trigger. Question # 11 of our FAQ will allow you to choose between these two models.

Brake cut-out / regeneration option :

The brake cut-out is not necessary for the proper functioning of your motor but offers additional safety by grounding the system during braking and is strongly recommended if you use a cruise control.

it is in the form of a contact brake handle for bicycles equipped with cable brakes or a magnetic contact or a simple push button for hydraulic brakes.

If you use a direct drive motor, the brake cutoff will activate the regeneration to recharge the battery when braking or downhill.

Cycle analyst :

The controller is wired to receive a cycle analsy V2.4 or V3.

The cycle analyst is a truly board computer, more advanced than other LCD display proposed in 250W and 750W kits or pedal motor.

The cycle analyst displays all the electric data of your motorization and your battery. This will allow you to set your settings and loop your regulation system. To get more information about the cycle analyst please see our tutorial videos and read our utilization notice.

Torque arm : is a stainless steel shaped with a laser to avoid fixation screw loosening of the drive wheel and to don’t ruin the bicycle frame.

The torque arm is essential for freeride kit.

To choose your model for your bike please read the manual on torque arm’s role.

Freeride motor : is compatible with all Shimano and SRAM cassette in 7,8,9 speeds.

So, you can recover the cassette of your original bicycle or buy once with your kit. We will install it of the wheel.

Please note that if you have 7 or 8 speeds, you’ll have to take cassette spacers to adapt it on the motor.

Cruise control : The controller has a connector to plug a speed regulator. Accelerate until the cruising speed you want, then let go the accelerator and the electronic regulates the motor to conserve a constant speed.

Really useful when you are following a group who don’t have the same motors.

Pedal sensor :

If you chose the pedal sensor and you want to get multiple assistance modes, you’ll have to plug the 3 positions switch on the dedicated connector on the controller. The 3 modes are: 30%, 60% and 100% full power. If you have a cycle analyst, you can control by yourself the speed level.


The thru axle is compatible with all the bikes equipped with a back wheel in 12x142mm and 12x148mm.

Please be sure that the installation is possible by verifying that you have a closed frame of 142mm or 148mm.

With a ruler, measure the interior width of your frame (A value). You must get 142mm or 148mm.

Then measure the axis diameter (B value). You must obtain 12
