I recently bought a Radrover and Radcity Step-thru. I also got the 1 Up USA Super Duty bike rack to transport the bikes. All is going well, however I want to get fenders for the Radrover. The step-thru bike came with fenders, so when I clamp down the arms of the bike rack, the arms come down over the rear fender. I put pipe insulation around the piece that touches the fender, but I feel this is less secure than if I clamped it down onto the tires. I like the looks of the Radrover fenders and can use the same technique I use with the Radcity. I’m wondering if it would be more secure to get some other type of fenders that will allow me to clamp the rack arms down on to the tires?
