Zero DS 2014

Zero DS 11.4 range test, because that's the first thing you are going to ask. TL;DR version is that I can ride further on a bicycle, not as fast though.
Baulkham Hills to Wisemans Ferry and return. I went out early so there were no other vehicles (except cyclists) on the road. I stuck to 60kph the 54.5km outbound trip and the display reported 68% remaining and 126.8km range remaining. I did notice on the way there that the regen braking wasn't doing anything, a concern.
On the way back I rode to the posted speed limit and watched the range on the dash drop quickly.
About 1km from home the display was at 27% and the power dropped and my speed was limited to 60kph and kept dropping until 40kph was all the bike would do. The last 26% was useless.
The battery isn't particularly healthy.
