FAQ
What are the advantages of this kit over other Bafang BBS-type pedal motors?
The kit with the TSDZ8 motor offers several distinct advantages over the Bafang BBS02. First and foremost, the TSDZ8 is designed to offer significantly more torque, with 110Nm compared to the BBS02’s 80Nm, which translates into better responsiveness and performance, particularly when climbing or on difficult terrain.
In addition, the TSDZ8 incorporates a high-precision torque sensor that adjusts assistance more finely and progressively according to the force exerted on the pedals. This feature ensures a more natural and intuitive riding experience than with the BBS02, which relies more on a rotation sensor to regulate assistance.
What’s more, the TSDZ8 benefits from improved heat management thanks to a design that facilitates heat dissipation, increasing its durability and resistance to prolonged use or demanding conditions. This robustness is enhanced by strong internal components and a larger gearbox, improving the longevity of the motor as a whole.
If you’re looking for a bike electrification system that combines high-performance assistance, advanced technologies and optimized ergonomics for the most enjoyable riding experience, the TSDZ8 kit is a great alternative to the Bafang BBS02.
If you have any further questions about installation, performance or choosing the kit best suited to your needs, our Syklo team will be happy to assist you.
Is the electrification kit easy or complicated to assemble?
The TSDZ8 motor kit has been designed to simplify installation, similar to the TSDZ2(see our tutorial here), on a wide range of bicycles with standard bottom brackets (BSA or JIS). However, depending on the specifics of your frame and the equipment already on your bike, certain adaptations may be necessary. We invite you to consult our compatibility manual , available here. 👍
For those who feel less at ease with bike mechanics, it’s a good idea to call in a specialist. If you choose to buy a kit via Syklo, ask us for a list of partner workshops ready to help you in this process.
Why a torque sensor motor?
The torque sensor analyzes the pressure applied by the rider on the pedals and adapts the electric assistance provided in real time. This type of sensor, renowned for its finesse, offers a more natural and efficient response than cadence or motion sensors(found in kits such as the Bafang BBS). Sensor accuracy may vary according to design and production, but the TSDZ8 kit is renowned for its high precision. Take care not to exert any pressure on the pedals during initial start-up (1 to 2 seconds) to ensure correct sensor calibration.
If you have the slightest doubt about your ability to install the kit correctly, the help of a specialist is recommended. When you buy your kit from Syklo, don’t hesitate to ask us for a list of partner workshops qualified to install it.
How heavy is the battery and how long does it last before needing to be recharged?
Battery weight varies according to the capacity selected, with the 840Wh model weighing in at 4.1 kg. Autonomy is influenced not only by battery capacity, but also by the level of assistance you choose when riding, and usually ranges from 30 to over 100 km per charge. The average consumption of an electrically assisted bicycle (EAB) is estimated at around 7Wh/km. However, thanks to the torque sensor, your energy consumption is optimized, enabling you to make significant savings, easily reducing your energy consumption by 20% compared with a Bafang BBS02, for example.
How fast can my TSDZ8 electrified bike go?
The top speed achievable with the kit is around 45 km/h. However, depending on your bike’s rear cassette, the type of bike (MTB, VTC, Cargo, Gravel) and the size of the chainring mounted on the TSDZ8, you may be able to reach higher speeds…
What accessories are included with the conversion kit and what tools do I need to assemble my bottom bracket motor kit?
The TSDZ8 kit comes with the motor, battery, charger and display of your choice. Your kit also includes all the components you need to assemble it: screws, cables, cranks, clamps and a special wrench for the main nut. However, to ensure proper assembly, you will need the following additional 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 disassembly wrench for your model (available from any bike/sports store),
- Cutting pliers,
- Net brake (available from DIY stores),
- A few extra clamps
Is my bike's electric conversion reversible? Can I remove the kit if necessary?
Yes, the electric conversion of your bike is reversible and the kit can be removed if necessary to go on another bike. That’s the beauty of investing in a kit that can easily grow with your needs.
What is the warranty on the conversion kit?
Our bicycle electrification kit is guaranteed for 24 months from the date of purchase, provided it is used in accordance with the legal power and speed regulations. To prolong the life of your kit and avoid any problems, we recommend that you follow the recommended instructions for use, such as storing it away from humidity, using it at temperatures between -10°C and 40°C, charging the battery regularly, and avoiding use in extreme conditions. In the event of a problem covered by the warranty, our after-sales service will be happy to help you find a quick and efficient solution. For more details, see our terms and conditions here
Is the battery removable and can it be recharged off the bike?
Yes, the battery is removable and can be recharged away from the bike. We recommend using the charger supplied with the kit to ensure optimum charging. To prolong 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, as this can damage the cells. Remember to recharge your battery at least once a month, and never store it flat.
Are there any restrictions on the use of the conversion kit in terms of weight or type of terrain?
The electric motor kit is designed to be used with a maximum load of 150 kg on flat ground, however it is important to check that your bike can support such a load, and to check the bike manufacturer’s specifications for expected weight limits (usually between 100 and 150 kg). The kit can be used on most terrains, but care must be taken on very steep or uneven ground to avoid overheating the motor and battery.
Do you deliver within 24 hours?
We understand that you can’t wait to receive your order, but unfortunately we don’t offer 24-hour delivery. We work with fast delivery services, but our preparation and shipping team can’t match the processing speed of Amazon warehouses.
We have in fact adopted a 4-day working week, as we firmly believe in the importance of a healthy work-life balance. This means that our team is more rested, happier and more efficient when they’re at work, but it can also mean that the time it takes to process your order may be slightly longer than you’re used to.
However, rest assured that we will do our utmost to ship your order as quickly as possible, while ensuring the quality of our products and services. We believe that fast delivery is important, but we also believe that reliable, quality delivery is even more important.
