I'm planning to build my first e-bike but i'm doubting between 2 engines: the TSDZ2 or BBS02B.

I like the idea that when i press harder the TSDZ2 engine will support you more (superman legs). However, as i will be use it daily i have my doubts if it the smartest decision as not the best materials are used for it.

The BBS02B engine is more robust, has more torque but it works with a PAS system. If you don't know any better i believe that in general most people will like it.


What is the best choice, does anyone have experience with both the engines, preferable long-term.


To power the engines, i'm planning to buy the Hailong E-Bike 48V 17.5Ah battery.

BBS02 has many blown controllers as well.

the TSDZ2 is lighter and quieter.

Hello - I am looking at a BBS01 ETM or a TSDZ2 for my latest cargo bike. I am drawn to the TSDZ2 from Woosch but want a larger capacity 17-20AH 48v battery than they currently offer. Any recommendations for a suitable battery preferably bottle cage mount style case? Thanks

The 35E has the best capacity of all cells and life expectantcy if you restrict it to 1c or 3.5a max which means 17.5a max for 5 cells in parallel , following extensive testing of many cells this is the one NASA have opted for to use on there missions, though I think 0.3c is there usage of the cell.

Above 1c the GA is better, typically I'm not bothered about total claimed capacity down to 2.5a discharge but use 3.3v as my min discharge line and compare cells to this line.
