What can towing offer your family? The main advantage for towing is that you do some/most of the work for them and you make most/all of the decisions. Towing broadens where you can ride and how far you can ride with your child. As you are making the decisions you can take them into busy environments e.g. traffic that they would otherwise be unsafe in. You can also take them further or onto terrain that they may struggle to bike on their own e.g. up hills.
This provides more riding experiences for families with different aged children and can provide a greater variety of experiences at an earlier age. Your family is more likely to enjoy the riding experience if you are supporting and challenging each rider at their individual riding level and capability.
