only caps the top-end, not the bottom. I can climb like a banshee until I reach the speed threshold preset in SP-1, -2 and -3.
Conversely, back in early 2010 I tried to have the CA-DP throttle current and I experienced that previously mentioned surging issue
- which for me was not optimum. It could have been operator error, although I was too noob to know for sure. The concept is worthy of reinvestigation.
Setting the Phase Current lower helps prevent excessive use of power at the bottom end and directly translates to extended range.
2WD allows me to trim the Batt/Phase way down because I have two wheels sharing the load; better economy on steep hill climbing – however not as efficient overall compared to a single-wheel system where the rider can optimize their contribution by shifting to lower gears
, and hyper-miling on the flats.
