Because they said Harvester would kick in after 150 miles to stay ahead of charging the battery, they also said at reveal that the battery would run aprox 300 miles with extender turned off.
The Harvester kicks in after 150 miles of battery only driving in order to get ahead of the charging for the additional miles. You can select battery only and get 300+ miles of EV only range. It really is the best of both worlds. I would only select To have the Harvester kick in on extreme road...
I would assume the regen level is adjustable like most EV's. MY R1S is my first EV and I love one pedal and have the regen set to high. I have not taken it off-road, but interesting enough my Gen 6 Bronco has a one pedal driving feature for off-road that I use rarely.
Here's hoping by time of launch Rockslide Engineering has developed a set! I had a pair setting in my garage a long time before my reserved Bronco arrived at launch.
I don’t think the width dimensions are correct for the final version. If it is, they are going to have to add clearance lights like on the Bronco Raptor.
