Cargo bikes are for carrying ... CARGO! But, you say "bikes can't carry heavy and awkwardly shaped things?". That's where you'd be wrong.
If you’re looking to get small children around from A to B and you can’t fit them on your regular bike, there are loads of options out there! Or if you’re running a small business providing last mile delivery services and you need to get light cargo from A to B, it’s definitely worth considering a cargo trike.
