Re: Bafang SW102 Bluetooth LCD - OpenSource firmware and mobile app

Why take the risk while there are already 2 sellers negotiating with the manufacturer to flash on production our own bootloader on SW102? One of that sellers is already selling online TSDZ2 and KT-LCD3 flashed with our firmware. Why not trust them? Yes, thats the official way to go! I agree! +1

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

The first might be to use a generic Bluetooth bootloader based on the Nordic NRF SDK that we could give to Topology to preload at the factory, after which we can use Bluetooth to update the firmware. If it s possible, i thinck moving to SW102 will make ppl enjoy ( i hope for, because i don t want t...

Re: New "TSDZ2 Torque Sensor Central Motor"

Don t thinck it s a tsdz2, it look like a bafang or lingbei ...

No informations if it s a torque or just a pas inside .
Seem it s stronger than TSDZ2 as a BBS02 .

There is no other issue for a torque sensored motor exepted with bafang maxdrive, but it s difficult to find a frame with a cool price .

Re: Tsdz2 firmware open souce adapted to vlcd5

ok, you haven t less power, i thinck ( must use a wattmeter to be certain ) but as you use a 29' power is better used . 36v motor have straight use, it s better with open source firmware ( egual marcoq or full open source ) but you have less real torque with it than for example a yamaha or bosh moto...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

ok, it s different, i would ask, is your motor a 0 type ( 48V ) or a 1 type ( 36V ) ? as they all match 4000 rpm but 48V motor need 48 V to match it and 36V motor only need 36V to match 4000 rpm . With 14S battery 36v motor could run at 4000*1.40= 5600 rpm and 48V motor only 4000*14/13= 4300 rpm . t...

Re: Tsdz2 firmware open souce adapted to vlcd5

Look what casinho is saying on the other thread, is wife human power is less than is own, as the motor is using torque ( human power ) and assist is a ration of this, it s normal that someone with less human power can t reach the same power than stronger ppl . must put a stronger ratio asssist lvl o...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

Buba : Regarding motor cadence: as you already know, the nominal voltage on the 36 volt motor should be around 36 volts. If you put anything more or less you effectively change the motors RPM. If you were to put double the voltage it would double the motors RPM. In this case you wish to use a 12S b...
