I started out, convinced we would buy 2 Radcity's, then tried the Aventon Pace 500 ... made the Rad's feel like tanks ... then tried the new Espins, which were even better than the Aventon 500 in my, and my wife's opinions.
I was told by Kevin the owner of Ride1up, that the ride1up 500 and 700 reviews would be published in December. Bobby, the owner of Phatride in Scottsdale, where we tested the RadCity's and new, 2019 Espin Sport and Flow, said the EBR review of them will be posted soon also. They are really nice bikes, but recently raised the price to $1,799
I'll post a link to my review of them after this comment.
Lots of good choices coming, and for me, Rad's are no longer on my radar. Ride1up and Espin are way ahead in look and feel, performance, value and ride quality IMO.
