Are you sure you wouldn't be better off with something with a bit more oooomph, the poor old TSDZ2 must be having an asthma attack trying to pull that lot around.
Maybe. It was (is) my first and only motor so far, bought 4 years ago. But more than this would probably be a legal problem in the EU.
Still it supported first the huge rear bags, later the fully loaded trailer, and more recently pulling my GF with a hand held bungy on difficult occasional moments (she has no motor, so all the load on me, and I pull her only when she gets too slow). Granted, pulling two slim persons, two bikes, loaded trailer bags with heavy camping equipment uphill I can do it only at low speeds
Rest of the times the legal restrictions are my limits, not the motor itself.
The only real upgrade since then was a 52T wheelchain, a 11-50T cassette and removing front derailer. Now that I am replacing the blue gear (after 4 years, nylon again), found out and wanted to test what the new firmware could bring to it. And next upgrade/project, as I mentioned, solar power. The battery powers not only the bike but mini fridge, electric blankets, camping lights, phones, laptops, inflatable bed, etc. (I use a 48v - 24v 120W DC - DC converter to power most of the things). I might be pushing it too far, but it works well. and it is modular, so I can keep it as agile or heavy as required.
But honestly speaking, yes, when I bought 2 battery packs (one without cells for the DIY 13s2p) I had already in mind I the option of buying later a second motor kit (same or different depending on the experience) to have both bikes converted. I could move my TSDZ2 to my GF's in the future if you recommend something else for me
