I live in San Diego county, I recently tested the RadRover 6 Plus on the trail along the coast at Mission Beach. I own a RadRover 5. My impression is limited by the relatively level trail which did not allow me to test the hill climbing ability. However, I rarely, if ever, need more hill climbing power even living near the coast in an area where the coastal hill roads and trails are the norm. I felt that the motor gearing is not as well integrated as on the 5 model, it was noticable to me. The 5 motor gearing is as smooth and silk. I don't like the elimination of the USB port and I don't like the dual display at all. The small display is almost impossible to see in the bright sunlight (it seems to have a dark coating). I don't want to look at two different displays, and do not need any more information, but not being able to see it in the sunlight is a deal breaker for me. I do like the more precise battery indicator, however, I ride my bike 20-30 miles every day and the battery indicator always shows more than half power when I get home so there is really never a reason to care about the reading, the battery is never going to run out in the course of a day. I do pedal most of the time and use pedal assist 1 and 2 mostly and 3 for faster speed. Peddling and conservative pedal assist conserves battery power but still it is unlikely that you will ever use all the battery power in a day's ride unless perhaps you are on the throttle all the time. The hydraulic brakes are effective but so are the disc brakes and will stop the bike the same. The over all feel of the bike int terms of maneuverability and ride is the same. I didn't find anyting compelling about the new 6 Plus, when considering the additional $300 price, which is a testament to the RadRover 5. If both were the same price I would probably buy the 6, however, I don't think I would pay $300 more for the 6 if the 5 was still available. Either way, Rad bikes are awesome, the service is what it should be and more and you can't go wrong with either modle. If you don't already have a Rad then the 6 Plus has to be bought, it will put a smile on your face the first time you get out onto a trail.
