Bottom line
The Küat Piston ION is an e-bike platform hitch rack that supports up to two 100lb bikes on a 2" hitch receiver (80lb for RVs). Experts consider this rack a top-tier choice for owners of heavy e-bikes. This Piston ION accommodates wheelbases up to 57", wheels from 18" to 29", and tires up to 4.8". Off-road use reduces the weight limit to 50lb per tray. Testers praise the Piston ION's exceptional engineering and build quality, but it's heavy as a result.BikeRide finds and shows you the best prices of the bikes you want to buy.
