I think you are on the right track using the 48T narrow wide. I just used what I had when installing my mid drive (42T steel chainring) to see how it went and quickly realised I wanted a higher cruising speed without using the two smallest cassette cogs. I did the sums and changed to a flat...

Mine was bought in the middle of 2019 so think is still what anyone is getting now. At the yellow line the chainstays are 70 mm across to the outside edges and look to be symmetrical on that cyclocross frame. Photo is taken from the top (obviously) but also slightly forward. Trying to show that...

This is the only one I ever found. I added the 130mm dimension. Have you seen the TSDZ2 fitting promo video? https://www.youtube.com/watch?v=NveONkinTb4

Looking at those dimensions I would think a BBS01 would bolt straight up so if a standard BBS02 is the same it should fit too.

BBS02 with 100mm spindle would probably be ok. Consider using two straight crank arms to bring the Q factor in as small as possible and center the whole thing according to them using spacers both sides. As little as you can get away with on the right and all the rest on the left.

TSDZ2 probably not. I have two of these and did a quick measure. From the centre line of the BB measure back 3". If the chainstays (outside) are more than 3" across at this point it won't fit as intended. It will need to be offset to the right which is usually detrimental to the chain line, or...

I hope the upcoming 400z Proto gets some EV treatment eventually. Maybe PHEV.

I expect there are 10s of 1000s of these in circulation, particularly in China where the adult population weigh less (per person). Certainly the TSDZ2 hasn't been engineered for weighty westerners who then choose to fit them to full suspension mountain bikes and go do jumps. I'm 6'1" and 13...

Yep. Been ok the last few days. Thanks.

Been happening for over a week but does connect sometimes, like now.

In my 13s3p triangle example earlier I planned it out beforehand as best I could. I wanted to use the pre-formed nickel (with slits) to make the spot welding process less fiddly. In my low amp application I still wanted to have at least two serial connections between each trio of parallel cells...

Despite the oh so regular same old very vocal ones running the TSDZ2 down every chance they get, in certain applications, it is a very convenient easy to like setup. If someone needs to absolutely beat on it, the TSDZ2 is the wrong option. If someone doesn't ride well using the gears, the TSDZ2...

That Malectrics spot welder is the one I bought. It worked fine for me. As an example this is the 18650 (LG MH1 - 3200 mAh) 13s3p triangle shape I made. Bluetooth BMS (~150 x 65 x 12mm) sits along the top where it says 142. You should be able to come up with something in 52V flavour that will...

Play around with this battery shape configurator. https://e4bike.ru/page/battery-shape-configurator?c=41800201404196141480138446336197183

Just weighted my bike (well me then me holding the bike). Difference was 17.8 kg, so just over 39 lbs. Includes mobile phone and lights on the bike, 13s3p shrink wrap battery, but no water. I actually put my batteries together. I've made three. 13s3p in 13x3 oblong configuration. 2nd hand LG...
