I don't change the assist level on my cadence PAS system, I leave it in level 1 all the time, and change the effort required thru gear selection. Would that be the same on a mid drive torque system? Because the other option is the Bafang which is a cadence sensor mid drive, instead of the Tongsheng torque mid drive. i'm looking at a 36v. 250w for either, I don't want or need much power.
when I mean the most out of it I mean the most efficient. mid drives work best with a higher cadence then they are the most effort. Plus you are too it's easier to put out 400 watts if you're spinning 80 rpms then 40 rpms.
You would have to go to the biggest Bafang to get torque sensing. the 1000 or is it the 1200 watt? but their newest one has it. if you can live with the chainlink maybe putting a good sealant in the rear trie or going tubeless would be far easier and cheaper. There is torquer sensing for some Bafang hubs.
but torque sensing is going to be like riding your bike like you did without a motor. I shift all the time to keep my cadence even and I choose the assist level on how my energy level is that day. so I can work harder or easier in the same gear.
