Z8 motor installation
Step 1: Screw on tray and tray guard
Screw in the 5 small M5 screws using an M4 Allen key. Tighten to 10 N.m.
Step 2: Position the motor
Position the motor in the bottom bracket.
Make sure the motor does not touch the frame (this could interfere with the torque sensor and affect motor durability).
If necessary, add spacers (5 mm washers supplied).
The motor shaft must protrude at least 10 mm to allow the M33.5 mm nut to be screwed on.
Insert screws with spacers into the rear of the mounting plate.
Step 3: Attach the mounting plate
1- Insert the screws with spacers into the back of the mounting plate.
2- Fix the mounting plate to the motor without forcing it, adding a few drops of threadlocker is recommended.
3- Make sure you’ve fitted the right spacers for the size of your bottom bracket. If the spacer on the screw is too long to ensure that the plate fits properly, add a spacer on the chainring side (see step 2).
Step 4: Screw on M33 nut
Screw on the nut by hand, without forcing.
Position your motor upwards. Take care not to pinch the cables and sheaths running under your bottom bracket. If you do, use a shim to tighten the cable or re-route it.)
Then tighten to a minimum torque of 40N.m.
To ensure tightness, you can tighten to the maximum of your strength with the tool, then complete the tightening by using a mallet and tapping hard to complete the tightening with a ¼ turn of the nut(be careful not to twist the other end of the wrench).
Step 5: Screw in the M5 screws
Tighten the 2 M5 screws to a torque of 10N.m.
Take care to use the correct length of screw with a spacer behind the plate.
If the screw stops at the end of its travel without tightening, adjust the thickness of the spacers (on the plate side and behind the plate) or adjust the screw length.
Step 6: Screw on the M33 Locknut
Using the wrench supplied, tighten the M33 locknut to a torque of 10N.m.
If you don’t have room to fit the nut on the thread, make sure you’ve applied threadlocker to the M33 motor nut.
Step 7: Installing the display
Install the display on the handlebar, then tighten the screw without forcing (tightening torque: 0.8N.m).
Position the screen as close as possible to the left handle.
Step 8: Attach the cable to the frame
Adjust the cable length to maintain handlebar rotation range (tip: turn the handlebars all the way to the side opposite the cable, then adjust easily).
Then use cable ties to secure the cable to the frame (take care not to interfere with brake and gear cables and sheaths).
Step 9: Install the speed sensor
Secure the speed sensor with two clamps.
Attach the speed sensor magnet to a spoke, using a flathead screwdriver or pliers to tighten firmly.
Check that you have correctly positioned the magnet on the spoke (the screwdriver recess should be opposite the sensor) and that you have precisely adjusted the position of the magnet in relation to the sensor, ensuring alignment with the arrow drawn on the sensor. The ideal spacing is between 10 and 15mm.
Step 10: Install battery and connect cables
1) Mounting: Align the bracket with the frame inserts and secure with the screws supplied (2 out of 3 are sufficient).
2) Insertion: Slide in the battery and check that it can be easily inserted and removed. Allow sufficient space for manoeuvring.
3) Securing: Lock the battery with the supplied key to prevent theft or accidental detachment.
Good to know: Several configurations are possible depending on your bike, thanks to our mounting solutions.
Connect the battery cable.
Connect the display (large cable with black ferrule) and the speed sensor (cable with yellow ferrule) with their respective cables on the motor side, following the coding (align the arrows on each cable to be connected).
Important information:
Make sure that the cables are well embedded and therefore watertight. Also make sure that the cables are not hanging down or likely to snag, and take the time to add as many cable ties as necessary to keep the cables held tightly against the frame.
Step 11: Fit cranks, pedals and chain
Tighten the M8x14 screws on the cranks (supplied in the kit) very firmly(40 N.m), then fit the pedals (not supplied).
Be sure to respect the direction of the cranks: L for Left and R for Right.
Fit and adjust the chain if necessary; the chainring supplied with the motor is a 44-tooth chainring.
Important information:
Be sure to install the cranks on the correct side by checking the letter engraved near the thread.
“R” (Right) = Right crank
“L” (Left) = Left crank
Reversal can lead to incorrect installation. Take the time to check before installation!

What is an electric bike kit?
An electric bike kit is a set of parts that transforms a conventional bike into an electric one. It generally consists of a motor, battery, controller and control screen. The motor can be mounted on the hub of the front or rear wheel, but ideally it will be mounted directly on the crankset (perfect combo: efficiency / maneuverability) and powered by the battery.
The controller is the brain of the system, managing the motor’s power supply and ensuring that everything runs smoothly. At Syklo, we program it using our Open Source Software (OSF).
Last but not least, the control screen lets you view various parameters such as speed, distance covered, remaining battery life, current/average/maximum fuel consumption and lots of other useful information thanks to the OSF.
If you’re looking to convert your bike into a practical and economical means of electric transport, an electric bike kit is an excellent option.Please contact us if you have any questions about installing or configuring the best kit for your bike.

How long do your batteries last?
If you use a 360 Wh battery for your electric bike fitted with a TSDZ2 250W motor, range will depend on various factors. However, you can expect a battery life of between 40 and 70 km, depending on the frequency of assistance, the rider’s weight, weather conditions (wind, cold) and the terrain covered.
The lower battery capacity will also influence the overall weight of the electric bike. By choosing a higher-capacity battery, such as a 540 Wh, you can ensure a longer range (around 100km). However, it’s important to note that larger-capacity batteries will similarly increase the overall weight of your electric bike.
In all cases, our team can help you choose the battery that best suits your needs and your bike. Contact us for more information on our batteries and kits with TSDZ2 motors.

Is your kit Made in France?
Short answer: No.
Long answer: We’ve chosen to concentrate on the design, customization, programming and after-sales/repair of our kits here in France. But let’s face it, what really counts is where the components and raw materials come from. For the moment, we don’t plan to assemble the engine components ourselves, but we’re thinking about it, as the time required is low (around ten minutes) and it would improve our quality control, but we wouldn’t be so quick to talk about Made in France.
Is it legal to electrify a bike in France and Europe?
Yes, electrifying a bike is legal in France and Europe, but there are a few rules to observe. First of all, motor power must be limited to 250 watts, and the maximum speed must not exceed 25 km/h. What’s more, the bike must be equipped with a system that automatically cuts off electric assistance when the cyclist exceeds 25 km/h or stops pedaling. Wearing a helmet is not compulsory, but we strongly recommend it for the cyclist’s safety, as well as the installation of a powerful light and the wearing of a fluorescent vest (top of the class).
Our bike electrification kit meets all legal requirements in terms of motor power, maximum speed and automatic cut-off of electric assistance (the torque sensor automatically detects whether you are pedaling or not). So you can electrify your bike legally and without the risk of a fine.
However, it’s important to note that if you modify the kit to exceed the legal power or speed limits, you risk a fine and your bike will no longer be allowed on public roads. For your own safety and that of other road users, we recommend that you comply with the power and speed limits recommended by law. What’s more, if you modify these parameters (max speed and max power), the 24-month warranty no longer applies.
Our bike electrification kit is designed for moderate use. Any modification of maximum speed, power or intensive use at maximum power risks accelerating the normal wear and tear of motor parts.
What is the electrification kit warranty?
Our bicycle electrification kit is guaranteed for 24 months from the date of purchase. However, it only applies within the limits of use in compliance with the legal rules on power and speed. If you alter these parameters or use the kit intensively at maximum power, this accelerates the normal wear and tear of motor parts, and the warranty will no longer be valid. It is therefore essential to respect the legal limits and use the kit under the right conditions.
We also recommend that you do not allow the battery to discharge completely. Finally, use of the electrification kit in extreme conditions (mountains, sand, snow) may cause premature wear of parts and will not be covered by the warranty. It is therefore important to follow the recommended instructions for use to prolong the life of the kit and avoid any problems. If you have any questions about how to use the kit, please do not hesitate to contact our customer service department for advice and recommendations.
To sum up, here are the points to keep your warranty in force for 24 months, or even better, to exceed 5,000 km in 2 years without major maintenance👍:
- Use in compliance with legal power and speed requirements
- Use of the kit in the right conditions (no intensive off-road use, no loads exceeding 150 kg)
- Store under cover to avoid exposure to moisture.
- No immersion in water or near fire
- Operating temperature from -10°C to 40°C
- Battery storage ideally between 15°C and 25°C
- Monthly 10-15 minute battery charge when not in use
- Do not allow battery to discharge completely (can be programmed via OSF)
- Avoid use in extreme conditions (mountains, heavy rain, sand, snow).
In the event of a problem covered by the warranty, our after-sales service is at your disposal to find a quick and efficient solution (always giving priority to repair rather than replacement).
We’re convinced of the quality of our electrification kit, and we do everything in our power to guarantee the best experience for our customers.
