TSDZ2 w/ VLCD-6 (Km/h Only) - Torque Sensing Pedal Assist (36-52v / 10-18a / 250-750w)

Tongsheng TSDZ2 w/ VLCD-6 Display - Torque Sensing Pedal Assist Mid Drive E-bike Conversion Kit

     The TSDZ2 Mid Drive Motor - Torque Sensing Pedal Assist: The harder you pedal - the harder the motor works with you. 4 levels of assist provide smoothly integrated power ranging from +36-300%, allowing you to conquer virtually any hill with ease. These kits retrofit most bicycles by replacing the bottom bracket & crankset assembly - to utilize the existing drivetrain & gears for maximum efficiency.

     The VLCD-6 Display - Compact Left Handlebar Mount:The VLCD-6 Display Mounts on the left side of your handlebar and is the smallest of the TSDZ2 Displays. Featuring a power button, and up and down buttons to cycle between the 4 levels of assist. This is a Km/h only display - no MPH option.   

DISPLAY:

     GEAR:

     The stock blue plastic gear is a bit quieter than the metal gear, but if you ride aggressively at maximum power, at low RPM and high gear in hilly areas, or haul a trailer or heavy load, you may want to consider the metal gear. We offer it pre-installed as an upgrade in any of our TSDZ2 Systems.

     SPEED SENSOR:

    The speed sensor attaches to your chain stay, and the spoke magnet screws onto a spoke to provide an accurate speed measurement. You must set the gap between the sensor and the magnet to right around 1/2" (12mm) and set your wheel size from the display. Start with a bigger distance, and then bring it closer just until you get a solid reading. Too close will scramble the reading. This model includes the 'Y' splitter speed sensor with light cables, for optional lights controlled by the display. You can leave the light cable uninstalled if you don't plan to use it. We also have the standard speed sensor without the splitter/light cable (pictured in the second thumbnail above) if needed.

     EXTENSIONS:

    Extensions are available in the parts and accessories section for the speed sensor and VLDC-5 external button panel. We can also make custom length throttles and e-brakes. If you need extensions for every part, please see our 'Trike' Model.

      BICYCLE COMPATIBILITY:

      The TSDZ2 Mid Drive Kits are designed to fit bikes with threaded JIS/BSA bottom brackets. This means a 68mm (2.68 in.) to 73mm (2.87 in.) wide bottom bracket shell (unless you have the 100mm TSDZ2 model, then 100mm is the desired measurement) and 35mm (1.37 in.) inside diameter. Known as JIS or Japanese Industrial Standard, which is very similar to our standard here in the US commonly referred to as "square tapered spindle", ISO/English, BSA, British, or "threaded". More than 95% of bikes with the correct measurement bottom bracket will work without a problem, but keep in mind, after 2012, a lot of higher end and full suspension bikes started utilizing other types of bottom brackets. PF30,  BB30, and Shimano Press Fit 41 BB92 do have adapters on the market to make this motor compatible, but other style bottom brackets not mentioned are incompatible without custom machining.

     INSTALLATION:

     To prepare, you need to have a compatible bare bottom bracket shell. If you are doing a conversion with an existing bicycle, you will have to first unhook the chain from your current chain ring, and uninstall and remove the complete bottom bracket assembly from your bicycle. For the VLCD-6 Display, you will also need to remove your left grip, and possibly more depending on the order of your cockpit setup. Once you are prepped for the install, the steps are as follows:

1. Insert the TSDZ2 axle through the bottom bracket shell of your bicycle, and on the protruding side, slide the TSDZ2 mounting plate over the axle, then secure to the motor housing with the included bolts. If you have a 68mm bottom bracket, use the two included 5mm spacers, if you have a 73mm bottom bracket, you do not need the spacers. Fasten the included TSDZ2 lock ring over the axle, and tighten firmly with the included tongsheng wrench. Now, re-tighten the mounting plate bolts. Keep in mind, if this is a conversion, when putting your chain back on, you may need to add or take off some chain links for proper tension depending on the size of your old chain ring.
2. Slide the VLCD-6 Display over your bicycles left handlebar and tighten down the hardware.
3. Connect the VLCD-6 6 pin cable to the corresponding plug on the motor, connect the power cables from the motor to your battery's discharge cables, and connect the TSDZ2 Speed Sensor cable to the corresponding plug on the motor. Take care not to bend the pins when connecting these.
4. Fasten the Speed Sensor to your bicycle's chain stay with zip ties and secure the Spoke Magnet to your spokes. Ensure that the magnet lines up with the sensor arrow, and that there is a little gap in between them as well. The sensor is very sensitive, and will scramble the reading if the magnet is too close when it spins. Start with a bigger gap, and then bring it closer until you get a solid reading, looking for a final gap of around 1/2" or 12mm. You can also cover up the sensor with a chain stay cover, to additionally hide and protect it, and this will not inhibit the reading, or perhaps you may just have to move it a tad closer if anything.
5. Connect the front/rear light cable to the 'Y' adapter on the speed sensor cable, and run the cables to the front/rear accordingly. Wire them to your lights however you choose.
6. Power on your display/motor, ensure your speed sensor, lights and motor functions are operating correctly. Adjust your settings from the display as needed.

* Note - While TSDZ2 will function without the speed sensor or lights connected, it is highly recommended that you install them as is required by law in some areas.
