I haven't been active on this thread since page one much but have been following it with interest. The potential I saw in mid '19 for the M600 seems to finally becoming fulfilled. However there is still a question in my mind at least of the long term reliability of the motor and what Bafang is doing...

Re: Help with specialized fatboy expert fitting hub motor

Looks to me like you should mill the dropout some to get the axle deeper into the dropout. A 10mm rotary burr file would help best but can be done with a dremel tool or round file. Just be careful to be symmetrical about it.

Re: Testing new bbshd fatbike climbing ability in sand

Nice playground. I have similarish sandy terrain to ride on but not as open in the trees here in OR. There is a 5 mile stretch of beach I ride regularly, tide depending, but I get by without a fatbike no problem. In fact I ride 1.5 tires on the beach but usually my 2.3/2.8 combo.

Re: TSDZ2 question

My first conversion was 3 years ago and as I was using mechanical disc brakes I used the TS levers. I did find it useful after awhile to slightly depress one of the levers while shifting that shut down the motor, sort of like a clutch. I decided to go with hydraulic discs two years ago and so the st...

Re: TSDZ2 - topspeed on pure throttle?

42/18 is only a 60" high gear which might get you to what was mentioned depending on how much you weigh. The TSDZ2 is not a good stand alone system for speed but does very well with a higher cadence pedaling input. My 42/11, 110" gear, spun out pedaling does a little over 26mph on level gr...

Re: TSDZ2 main shaft radial play

Basically the stock bearings the bb spindle ride on are crap. There is plenty of info on here about changing them out to better ones if you can sift through the large amount of chatter here about TSDZ2's. However it is a home repair job that not all are going to be willing to undertake.

Hi all. I have just completed 2 builds using the new E10 frame. Picture attached. I can confirm the battery is larger than the one in the M09 and is rated at 816 watts or 17 AH. The battery specification I received stated it uses 21700 cells but unless I open it up, I can't confirm this. The E10 as...

Not an uncommon issue with any of the kit bb drives. I use 42t, the smallest that will fit over the reduction housing, offset chainrings on my TSDZ2 bikes. They don't make any specific ones but you can mod the bolt pattern with a drill to fit the standard spider and some spacers. Will get the chain ...
