Looks good, isthd Battery in frame? This is certainly one to watch!On my short list of bikes to build is the Tern Link B7:
Tiny Xiongda rear hub motor (sensored version) with DNP 11-32 freewheel, controller behind seatpost, Magura HS11 on the front, mudguards, battery powered b+m lights, Big Apple Plus and the Tern basket on the front with a softshell battery. For moving more stuff around town I would use a trailer.
