Received my RadWagon 4 a week ago and have put just under 200 km on it! I love it. It's a great bike and what has surprised me is how much easier it is to ride with PAS than my RR+ was! The narrower tires really let you pedal as though you were riding a regular bike. Rad did a great job with the center of gravity as well. Makes hauling kids or cargo easy. I usually keep the bike in PAS 0 or 1 and just use throttle for the steep hils whilst peddling. You will LOVE it!
