2002 Rockhopper Will my shimano deore click shifter & brake combo interfere with the brake cutoff? Using bafang m625 or bbshd. options?

to first q, not sure about your shifter - brake cutoffs can be inline mechanical or hydraulics with magnets which are a bit more finicky. newer kits with torque sensing motors you dont really need brake cutoffs. recommend a cyc photon due to this. 2nd question - because the motors chainring replaces the front derailleur grears to do all the work for us, and adds a throttle/display.
