Mabman
E*POWAH Elite World Champion
The frame is a steel OS Brand, the private brand of an industry guy that I know. Pretty old school geo and nothing I would want to make into a mtb although that was it's original intent. The price was right...
Not a Bafang but a TSDZ2 running the Open Source Firmware. It's a kit type motor that has a decent torque sensor which Bafang lacks in their kits. My eMTB has the stock version and I have been riding it for the last 3 years. I never considered it for a road type bike until they came out with the firmware that allows for finite adjustment of all parameters primarily the assist levels as I require a natural feeling cadence while spinning on the road. MTB for me is more about just getting it done however you can cadence wise so not as important. Torque sensing is a must either way for a mid drive.
Technically it is a 48v/16A system so it peaks at 768w. However it has 20 levels of assist available and I rarely get up to 500w on the hills and the bike will cruise just fine at 250-300w.
The wheels are a bit unusual in that they are 40c tires mounted on 750d(iameter) rims, I guess you would say in the prototype stage? The overall diameter is 29"es so just that much bigger than 40c/700c. Maybe not the fastest off the line, the e assist pretty much takes care of that anyway, but get up to speed fast enough and maintain momentum much better than my comparable 700c bikes. I ride primarily gravel and it does that pretty well, certainly more entertaining than my mtb for that use.
18ah/864wh 21700 cell battery for the longer rides this bike is capable of.
Not much else special about the parts, just some stuff I had around as well as gathering from online and friends. I've been building custom bikes for myself since the 80's and just can't seem to shake it. It's a pretty fun ride but I have another same size wheel build underway with the front hub motor setup I have been using the last 3 years for any road use. Having some supply issues to get it done but should there eventually.
My plan is to compare the two drives for my use and ride the one I like best and use the other for a loaner.
