I’ve converted a few bikes to mid drive 750s/48 volts. I just got my hands on a 2019 Giant fathom for a steal. I want to throw a mid drive 1000watt on her. I’ve come across a few post’s where guys were having issues running these 1000w motors with 52 volt batteries. I believe it was some sort of interface issue with the control screen? Was curious if these issues were still manifesting themselves with the 52 volt batteries? Also, if anyone has any suggestions or things to be aware of regarding this model bike and the conversion, please chime in. Thanks in advance!!! Derek.

Nope no issues with running a 52v 35ah battery and a 60v 45ah battery on a lunacycle BBSHD with the off road programming.
I got the eggrider V2 display which allows you to control quite alot of settings/parameters within the BBSHD controller.


So, if you get an older model BBSHD you might run into troubles.
Look around for US made mid drikve ebike kits there are a few out there besides Bafang/Lunacycle

Ride Safe! :cool:

Did this kit fit? Just looking into doing this on the same bike but looks like the bottom bracket is 79mm wide? Will it work

Been in some bafang facebook s**t, and the eggrider s**t, now the bbshd can be paired with a 72v no problems.

They had some problems 2021 and earlier stock controllers. As far as i have read an am aware now, no worries with a 72v
but a 90v i heard messes with the display currently.

exactly....anything below 2019 seems to fluster the the whole system.
some 2021 models will work with anything up to 72v but as far as i seem them talking about, still with issues.

So yeah, get the right controller for your BBSHD or enquire with the BBSHD, Bafang or eggrider people on facebook that tune these to
beat them up.

I got mine from luna with the hot rod programmed ludicris v2 controller.
