Hello, I am Dirk, 59 from Brasschaat near Antwerp, Belgium. I have a Stromer ST2 for home -work travel, and a Lapierre esensium 5.2 for my vacations in Calpe, Spain. With the X35 ebikemotion system. I have heard that for the X35 there is a way to speed it up to 30 km/h. I am looking for some information and hope to find it here. I love the bike and for uphill it is now perfect. But when the road goes a bit up and down and the group I ride with goes around 28 a 29 km/h it goes a bit to fast for me. Therefore my search.
