All together now!
After a bit of puzzling over part of the assembly instructions, here's the finished result. It has seven gears and either zero assistance or five selectable levels of brushless motor support. The model is T1 (trekking, good around the city, too), distinct from the M1 mountain version. I like it!
Convenient to use and good exercise, with no CO2 emissions apart from the production of the food I eat to metabolise and have the energy to pedal it! The electricity comes from the solar panels on our roof.
For the technically minded, 36V, 25km/h max motor support (legal restriction) and an impressive maximum torque of 50N/m.
