I just purchased a 2014 Rambler with a Nexus Hub and Patterson front transmission. I am trying to decide between a BBSHD and a geared hub motor such as the MAC 6t. I live in a hilly part of NY State and would like speed and to be able to pedal at speed (30-35 mph with front fairing on the flat ideally.) I have two other BBSHD bikes and certainly there is greater wear on drive train. At the same time, I don't know how well the MAC 6t will climb our hills.
The BBSHD will sacrifice the Patterson and the hub motor will sacrifice the Nexus.
Any feedback you can offer, I appreciate!
