OK, that helps. So the Hydra is not all the way there but not bad either?... https://wattwagons.com/products/hydra And which Dengfu frame is that? Custom to Wattwagons?

This isn't a terrible deal... What do you think of the geometry on the E05? https://www.ebay.com/itm/29er-Carbon-E-bike-SRAM-12s-Suspension-Mountain-bike-Bafang-Electric-Bicycle-20/174558544747?hash=item28a480036b:g:KckAAOSwasNdcMlI

That's encouraging. Do you know what crank speed keeps the motor in the sweet spot between max efficiency and sustainable power output when at 52V and using the open-source firmware? I know that's a little bit of a loaded question because ambient temperature affects how much heat can be...

You are correct - 125w is about 125 bpm (aerobic fat burning zone) and roughly 17 mph 185w is about 145 bpm (not anaerobic threshold yet) and about 20 mph I can do a 30 min time trial on my road bike at just under 25 mph with some rolling hills. Just above anaerobic threshold of course. These...

I just punched in my data into a bunch of online cycling speed/watt calculators. It looks like I need to maintain 600w for 31mph (49.6 km/h). If I contribute 125w easily that means I need only 475w from the motor. That is 300% assistance level. Maybe this is the limit of the motor... I don't...

I'm thinking about a new build using a Motobecane 2019 SRAM FORCE1 Disc Brake Reynolds 853 Steel Cross Bike. I would switch out the tires to 700C 40C with low rolling resistance - The motor would be FOS ready from these guys - https://www.electrifybike.com/store/p113/TSDZ2.html#/ Looking...
