Gazelle is a Dutch bike company and this is their high-end Type 1 E-bike with a Bosch motor (in the pedal/crank area) and Bosch battery. This is the most modern bike there is.
Being a Dutch bike, the seating position is very erect, so all of these bikes are step-through. There is no leg-over version. This is the Large frame, suitable for tall people.
The bike is "chainless", with a Enviolo drive system. Enviolo is a robust, stepless shifting gear hub lets you adjust gearing at the handlebars to get just the gearing you want--without going through the intermediate gears. The drive system uses a Gates CDX belt instead of a chain. Tensioning and lube are not required. The belt quietly does its job and is low maintenance.
