Convert a full suspension MTB into an E-bike with TSDZ2
HTML-код
- Опубликовано: 14 окт 2024
- I built a 36V 350W TSDZ2 Tongsheng mid drive motor with torqe sensor into this full suspension bike with a 36V 12.5Ah battery. The cost of the conversion was under $500 and I was done within two hours. This motor now has helical gears, so it runs very quietly. If you want to convert your bike yourself, note that it can be fitted in the 68 and 73 mm wide bottom bracket positions.

If you want to offend someone, this one or bafang bbshd? Greetings
Both have advantages. The TSDZ2 has torque sensor, thus the riding experience is very natural. An ideal training partner, the harder you press the pedal, the more assistance it gives. Because of the torque sensor, it is more complicated and more prone to failure. If it's important for you the natural riding experience, the smooth operation, choose it. The BBSHD is a very reliable motor with low maintenance requirement, but a bit too strong for a bike in my opinion. If raw power is important to you, if you want to climb steep hillsides, you can choose the BBSHD, but this performance will require a strong frame and a high-capacity battery. (The more powerful the motor the larger the capacity of the battery is needed so that the battery can withstand the higher current consumption.)
I haven't tried the BBSHD yet, but I had a PAS sensor bike , that's why I say torque sensor drive is better.
So it is not so easy to decide which choice is best for you.
Hello, I was thinking of getting a tsdz2 36v 350w for commuting and would like to know what is your comfortable cruising speed on highest assist? And what chainring are you using?
Hello, I have a bike almost identical to this red Merida with 26" wheels, off-road tires and a 11-tooth smallest rear sprocket. The comfortable cruising speed is about 35-37 km/h with the 42-tooth chainring when the wind is not blowing against me. I have tried the 52-tooth chainring. Without headwinds, it can be maintained at speeds of up to 42-45 km/h, but as I mostly ride on cycle paths, in crowded places and off-road, that was too much for me, so after two months I reverted to 42 sprockets, because they give more torque due to the many stops at the start.
@@mcelec7603 Thank you for your response! I already have a 27.5" mtb with 250w rear hub motor and get 37 km/h top speed on flats. So if the tsdz2 350w will get up to the same speeds comfortably, then I will buy it and fit on to another mtb I have laying around.
Another question, Do I need the same vlcd5 display you have to get to 35-37 km/h? Or will the smaller vlcd6 do the job? I heard you can change the amps on the vlcd5, but not on the vlcd6.
@@topherlou3250 I don't know the vlcd6 display, on vlcd5 the amount of assistance is configurable. On my own bike, the XH-18 display also does not allow you to adjust the strength of the boost except the 4 predefined levels.
@@topherlou3250 You should flash the controller with the custom firmware - then you can select and configure most adjustable things - a better display helps but it is not needed. I own xh-13 and vlcd5 displays
@@mcelec7603 flash your controller with the custom firmware then you can adjust the strength of each boost level (boost 4 isn't even 100% with the stock firmware)
The front derailleur left? What is the reason?
The front derailleur is set to a fixed position because it might help to keep the chain from falling off the front chain ring on the wrong road. I've dismounted it on my own bike, but the chain on the front chain ring sometimes goes off.
Can you use a 52v battery on these 48v motors ?
Since I haven't tried it, I can't give you an exact answer. Supposedly, it can be used, according to some descriptions, the switching transistors of the controller are at least 60V. Of course, without fw modification, the battery level indicator will be inaccurate.

Put some disk brakes on that
Yes, oil disc brakes are almost a must for an e-bike.
