I have a new rear cycle carrier -saris bones which fits onto rear bumper and boot of my saloon car.Could not afford the preferred thule with towbar carrier, but the saris looks sturdy enough.It has max weight allowance of 34k, which is ok for my electric bike is about 22k without battery.just to point out have not been on road yet trying it out, but the one concern i have is the weight distribution, with the motor on the rear wheel will this make it dangerously unsteady, just wondered if anybody else has experience of cycle carriers and e-bikes.
