This thread is for the general discussion of the Article 120 Nm update for the Bosch CX and CX Race Announced. Please add to the discussion here.

@Greg Watts I would hope a new Shimano motor would be lighter than 2.7-2.8kg as the current EP801 is just below that. But who knows. The Performance CX can be weaker than the EP801 while still being an efficient motor, can't it? It seems the power output curve is tuned differently. The CX 100...

@Greg Watts Are you sure about those motor characteristics? When testing various motors using garmin power pedals, we find the EP801 ramps up just fine. When riding our test climb, the EP801 gets up the hill with a similar rider input to the Avinox at 65rpm, the CX gen5 needs more rider input...

@Greg Watts How does the Shimano EP801 performance at low cadence, say 60-70 rpm compare to the Bosch CX gen5 and the Avinox M1? Also, do you recon we'll see a new Shimano motor soon?

@Greg Watts Do you know the history of the Forestal range extender? Why did it take so long for it to come out? Did they have to go with a different manufacturer/supplier?

@Greg Watts That's a fine list, I can't see anything wrong at first glance, it covers all the motors used on emtbs it seems. It seems the list formatting doesn't work as intended though. But I question what you go on to write below the list. l could be missing some context, but the PW-CE isn't...

@Greg Watts The peak power of the PW-XM, and PW-X3 for that matter, is just 500w? Are you sure? I don't know the peak power, but it seems low for a motor that is strong at low cadence and doesn't fall off as quickly at higher cadence, like the older models did. Also, there are a few models...

@Greg Watts Good morning, another 50% older today. Can you list all the pedelec motors Yamaha has ever made? I'd like a list/table showing motor name, torque, peak power if available and the year it was launched.

Yeah, it's even using emojis :)

Yeah, I've noticed these LLMs don't do well with this kind of questions, can be the same with photo equipment etc. Just going through its answers quickly I notice some weird errors, but there could be more. On its second attempt, Watts decided to include RM Instinct and Moterra SL, which is...

@Greg Watts Thanks, there are some models missing though, could you include these in your list? https://www.bosch-ebike.com/us/ebikes/mountainbike/light And make the list compact, no extra linespacing or indents that appear to mess up the formatting. Just the list, no elaberation.

@Greg Watts I guess I should have mentioned I want a list with just full suspension emtbs running the SX motor, which now is 60Nm tbw. Just a short list, no need to elaborate.

Hey @Greg Watts , can you list all emtb models using the Bosch SX motor please?

No, not a tabless design. But it seems the m65a has an improved tab design that shortens the path which current travels. A tabless design is more complex, it's more expensive and potentially less safe. Albeit not tabless, the m65a is quite a step up from the LG m58t in every way. Except for...

A solid state battery was initially described as having a Li-metal anode and solid electrolyte. It was imagined reaching a gravimetric energy density of 800 Wh/kg or more. I can see no indication of Donut having built what we initially understood as a solid state battery. The density seems to...
