We recently moved to the Netherlands and a popular mode of transport is cycling. We also have 2 boys that needs to be transported, so we bought a “bakfiets”. As you can imagine this becomes relatively difficult to pedal (heavy bakfiets + two boys), so I decided to buy some components of Amazon to electrify it. 

Most of these parts are at iteration 3 (or more), but finally everything fits well, and is strong enough to withstand all the bumps in the road.
