With the Milan, you can take the seat out of the vehicle with a single movement and gain access to the rear swing arm, pulley box or the seat adjustment. If you remove the protective cap from the pulley box, you can easily access the pulley.
If you want to mount it on the rear wheel, you can remove the service flap at the rear using a Velcro fastener without tools and then access the rear derailleur, axle and drive. The best way to do this is to stand the vehicle on two trestles so that you can work comfortably in a chair.
If you want to reach the crankset or the bottom bracket adjustment in the front of the front, it is best to sit relaxed in the Milan on the seat and from there you can reach all parts in the front. So you can e.g. Move the bottom bracket and at the same time check the correct distance on the roller. This is another benefit of the Milan’s oversized entry opening.
