Hey @Sean C. - Not sure how you got on with the new bike hunt, but if you wanted to up the range of your current bike - I just added a secondary battery to my Rize RX and upped the range to >90km pushing haaaarrd. I did a quick write up here...
Making a WIP post as I lost my first lengthy draft :(
Please excuse mistakes - I'll update this as I can.
I was frequently running-out my stock 15Ah battery on the Rize RX 2021 on rides about the city and quickly researched range extension options for the new whip.
Creeping around these forums...
Hey @wanders - you are correct. I ordered from @Jenny Mao and they supplied an alternate connector that is the same fit.
I'm overdue to write up the install and initial thoughts (I wrote out the whole thing, saved it as a draft on here and lost it 😭).
I'll see if I can get the pictures back on...
Hey - I have an RX and just added a 25Ah 52V secondary battery. My battery has a 30Amp BMS and it works fine (2nd battery only, rize original only, & both simultaneously).
