The Tesoro has a Supernova M99 Mini Pro 45, which has a 16w high beam that I never use. A lot of these lighting specifications come out of European regulations for Class 3 s-pedelecs, which they treat a lot like motor vehicles. Licensed, plated, regulated. The Moterra is an e-MTB (great bike), and when riding after dark in the woods, you can use all the light you can get.
