Avis des clients
Any questions before you saddle up?
What are the advantages of this kit compared to a front- or rear-wheel drive kit?
The TSDZ8 kit is equipped with a mid-drive motor, which provides better weight distribution and a better riding experience compared to front- or rear-wheel motor kits (electric wheel kits). This also means that power delivery is more efficient, which can extend battery life and provide more effective assistance.
The controller is the brain of the system; it manages the motor’s power supply and ensures that everything is working properly. It is this controller that we program at Syklo using our software.
Finally, the control screen lets you view various parameters such as speed, distance traveled, remaining battery life, instantaneous/average/maximum power consumption, and lots of other super-useful information, thanks to our in-house software.
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.
Is the conversion kit easy to install on all types of bikes?
The TSDZ8 kit is designed to be easy to install (tutorial here) on most types of bikes with a standard bottom bracket (BSA or JIS), but there may be differences depending on the frame type and the bike’s existing components. Please read the compatibility guide here carefully 👍
Otherwise, we recommend consulting a professional to install a kit if you’re not confident in your abilities. Buy a kit from Syklo and ask us which workshops we work with.
What is the difference between the TSDZ2B and TSDZ8 engines (and is the TSDZ2B still available)?
The TSDZ2B motor is no longer included in the Urban Explorer kit: it has been replaced by the TSDZ8, which is more robust and significantly easier to repair. On the TSDZ8, the controller is external, removable, and can be replaced more quickly than on the TSDZ2B. The TSDZ8 also offers slightly higher torque and power. We continue to provide support and parts for TSDZ2B kits that are already installed.
Why did you choose the TSDZ8 even though it weighs 1 kg more than the TSDZ2B?
The TSDZ8 weighs about 1 kg more than the TSDZ2B, a choice we fully stand by: we prefer a kit that’s much more reliable over time and can be repaired in just a few minutes. This slight increase in weight is fully offset by our new ultra-compact batteries, which are lighter and easier to fit into any frame, even the narrowest ones. The result: an ideal electrification kit for any setup requiring a high-torque mid-drive motor paired with a discreet battery.
How does the torque sensor work, and how accurate is it?
The torque sensor measures the force the rider applies to the pedals and adjusts the pedal assistance accordingly. The torque sensor is more accurate than speed or rotation sensors (found in Bafang motor kits such as the BBS01), which allows for more natural and efficient pedal assistance. The sensor’s accuracy depends on the model and build quality, but the torque sensor in the TSDZ8 kit is considered highly accurate. Please note: Be sure not to put your feet on the pedals when starting off (for 1 to 2 seconds) to allow the torque sensor to initialize.
Otherwise, we recommend consulting a professional to install a kit if you’re not confident in your abilities. Buy a kit from Syklo and ask us which workshops we work with.
How much does the battery weigh, and how long does it last before it needs to be recharged?
The weight of the battery depends on the capacity you choose; the 250Wh battery weighs 1.5 kg and the 630Wh battery weighs 3.1 kg. Range also depends on the capacity and the level of assistance used, but generally, the battery can last from 30 km to over 100 km per charge. It is estimated that the average energy consumption of an e-bike is around 7Wh/km. Thanks to the Open Source Firmware and Display Expert, you can accurately track your energy consumption and achieve even lower consumption levels (20% savings are easily achievable).
What is the maximum speed my e-bike kit can reach?
The kit’s maximum speed is limited by French and European regulations, which set the limit at 25 km/h. However, with the Expert display, the maximum speed can be adjusted (by entering a password); your e-bike will then be illegal on public roads, and you’ll be able to easily exceed 35 km/h (be aware that this may cause wear and tear on your electric kit: our 24-month warranty will no longer apply).
What accessories are included with the conversion kit, and what tools do I need to install my bottom bracket motor kit?
The TSDZ8 kit comes with the motor, battery, charger, and display you selected. In addition, your kit includes all the components needed for assembly: screws, cables, cranks, cable ties, and a special wrench for the main nut. However, to complete the assembly, you will also need the following tools:
- Allen key sets (2.5 mm / 3 mm / 4 mm / 5 mm / 6 mm),
- Phillips and flathead screwdrivers,
- Torque wrench (optional),
- Crank puller (available from any bike/sports store),
- Bottom bracket removal tool compatible with your model (available at all sports and bike stores),
- Cutting pliers,
- Threadlocker (available at all home improvement stores),
- A few extra clamps
Is the electric conversion on my bike reversible? Can the kit be removed if necessary?
Yes, the electric conversion of your bike is reversible, and the kit can be removed if necessary to install it on another bike. That’s the whole point of investing in a kit that will easily adapt to your changing needs.
How do I configure the different assistance levels from the display screen?
Assistance levels can be configured from the display screen using the buttons in the menu. Detailed setup instructions depend on the display model being used and are included with the kit.
What is the warranty on the conversion kit?
Our bike electrification kit is covered by a 24-month warranty from the date of purchase, provided it is used in accordance with legal regulations regarding power and speed. To extend the life of your kit and avoid any issues, we recommend following the recommended usage guidelines, such as storing it away from moisture, using it at temperatures between -10°C and 40°C, charging the battery regularly, and avoiding use in extreme conditions. If you encounter a problem covered by the warranty, our customer service team is here to help you find a quick and effective solution. For more details, please see our Terms and Conditions here
Is the battery removable, and can it be recharged separately from the bike?
Yes, the battery is removable and can be recharged away from the bike. We recommend using the charger included with the kit to ensure optimal charging. To extend the life of your battery, charge it after each use and store it at a temperature between 10 and 20 °C. Avoid letting the battery discharge completely before recharging it, as this can damage the cells. Be sure to recharge your battery at least once a month and never store it when it’s fully discharged.
Are there any usage restrictions for the conversion kit in terms of weight or terrain type?
The electric motor kit is designed for use with a maximum load of 150 kg on flat ground; however, it is important to verify that your bike can support such a load. Be sure to check the bike manufacturer’s specifications for the intended weight limits (usually between 100 and 150 kg). The kit can be used on most terrains, but precautions should be taken on very steep or rough terrain to prevent the motor and battery from overheating.
Do you offer 24-hour delivery?
We understand that you’re eager to receive your order, but unfortunately we don’t offer 24-hour delivery. We work with express delivery services, but our order fulfillment and shipping team cannot match the processing speed of Amazon’s warehouses.
We have indeed adopted a 4-day workweek because we firmly believe in the importance of a healthy work-life balance. This means our team is more rested, happier, and more productive when they’re at work, but it may also mean that the processing time for your order could be slightly longer than what you’re used to.
However, rest assured that we are doing everything we can to ship your order as quickly as possible, while maintaining the quality of our products and services. We believe that fast delivery is important, but we also believe that reliable, high-quality delivery is even more important.
Thank you for your understanding and trust. If you have any questions or concerns regarding your order, please feel free to contact our customer service team. We’re here to help.
