What are "ride modes" on the RM2 and how do they work?

There are three ride modes on the Maeving RM2 that affect the top speed of the bike. 

• Ride (1) has a top speed of 45 mph
• Sport (S) has a top speed of 70 mph
• Eco (E) has a top speed of 30 mph

Riding in the restricted modes (1 or E) will reduce the overall energy consumption of the RM2, allowing you to preserve or extend its range.
