Choose a route, any route. With its all-road capabilities and smooth, natural pedalling support, Roam E+ helps you ride smooth roads, rough roads, bike paths or trails. It’s fun, easy and ready to roll.
Engineered with a lightweight ALUXX aluminium frameset and a new SyncDrive Core motor, Roam E+ is all about versatility.

Comfort and control
63mm suspension fork and wider tyres improve comfort and control on rough roads or paths.
