The CO5 is awesome!!!
I purchased this bike 11/26/22 based on the advice of a friend who has been riding his about 6 months now, then purchased another one for his girlfriend a few weeks before I ordered mine. It came packaged very well. I watched the you tube video on the factory this week and am even more impressed. The customer service has been excellent and we were corresponding several times before and after my purchase so I don't understand why others have said they had trouble getting a response. It wasn't to difficult to put together but I took my time to be sure everything was just right. I didn't understand the cover on the charging port and unfortunately I pulled hard and broke it. It is supposed to slide to the side. I again emailed customer service and in a few days I had a new cover arrive in the mail and it was simple to change out. We all took our bikes camping and rode some of the bike trails at a state park. When we hit sand and it started to bog down, a little push on the throttle and it pulled out strong and smooth. As for the battery, no issues so far. I am so happy I picked this one and couldn't be more pleased.
