Hi guys,
after giving up on fixing my TSDZ2 - that served me well for 4+ years, I'm looking to replace it.
I have been using the old 36v MOTOR with a 48V controller and VLCD 5, no brakes, no throttle.
The bike have a Shimano hub gear, no coaster brake.
The first thing that comes to mind is a TSDZ2B, like
this one.
I'm in the EU and bought the last motor from PSW without problems.
Thought I'd check in with the pros before committing, here goes:
1. As I understand it the main difference with the B-model, except for some reinforced weak-spots, is less resistance when using the bike without motor assist? How much of a difference does this make? I DID find the old one not at all fun without motor assist.
2. The argument from the guy who helped me install the first motor when choosing a 36V motor, replacing the controller with a 48V one, was that this would eliminate need for high cadence to get good motor effect. I remember seeing different opinions on the subject in this thread through the years.
My old battery is not on PSW's webpage anymore. On screenshot from order page it says "48V 12.8AH Li-ion...Made of LG LGGBMH11865.." (SKU: PXL-SH-48128-LG) on the paper specs included it is called LX-B48132 made by Donguan Tongfu Electronics. It still works fine, so I would prefer to keep using it with the new motor.
Should I then get a 48V motor or a 36V one, but again replace the controller - possibly with the same 48V one used with the old one? What makes sense here?
3. How about the VLCD 5 display? Any particular reason to replace it? If so, with what and why?
4. Dito the question of flashing firmware. What would be the benefits to this, if any?
5. How about modifying the motor itself? I seem to remember some replacing the gear, improving heat dissipation etc on the TDSZ2's. Any recommendations?
6. Lastly, how about alternatives? I choose TDSZ2 over Bafang mainly for the torque sensor, but its seems they have models with this feature now, even though the ones I have seen cost quite a bit more. Is there reason to consider alternatives?
Cheers,
