Hi folks!
I recently took the plunge and upgraded? from a BBSHD to a GMAC + Baserunner on my Cargo bike. The first thing I notice is while I have significantly more top speed my hill starts are painful specially when loaded with my kid + cargo (roughly 350lbs with bike). Anything over 5% becomes painful and 10%+ is just not possible (if you stop, its impossible to start).
My battery can do 60A peak (52V 18ah Panasonics). What can I do to make hill starts and hill climbing better? My options are:
1. Upgrade to a frankenrunner
2. Upgrade to a bigger battery / BMS to match the frankenrunner max amps (96)
3. Add a geared front hub motor (ideas welcome on which one)
4. All of the above
I'm climbing hills in the SF Bay area (I live in Oakland) all day and don't like being limited by grade. I had no problems with my BBSHD cuz gears but wish to replicate something similar with a hub motor. The BBSHD was nice but 1 chain, 1 derailleur and 1 clutch later I'm done with that setup.
Thanks!
