To transport an Ebike in the rain, you may require considering how full your transporting vehicle is. And then, you may have to get rid of both wheels. In some situations, the saddle needs to go as well. Use a saran/glad wrap cling film for covering the chain area. Don’t forget to stash the frame across the back seat. You also need to bring along the tools that are necessary for reassembling. Another helpful tip is that if the bike frame fits inside the storage or trunk or boot, use that. Also, use fender friendly ebike racks.
