How to pull a mate up a hill?
Hello, I am planning a lunch with friends on a restaurant in the nature and we thought it would be nice to get there by bike. Problem is, the restaurant is on the other side of a hill and a friend of mine will not manage to get there with her own forces, as previous experiences had to teach. The climb is about 5 km (3.5 miles) long, 3 to 7% steepness, 300 meters (1000 feet) of height difference. I am confident to have the required strength to pull her up connecting our bikes with a wire, but I guess it would be extremely dangerous? Any suggestions about adequate equipment, maybe there is something made for children? Of course alternatives like renting a tandem or an electric bike have been considered, but are kept as a last resort because of the costs. Your suggestions are appreciated.
