Sporty efficiency

Adopt a sporty riding style and get further as a result – the Tour+ mode makes it possible. The riding mode rewards your slightly higher power input with energy efficiency: if you pedal harder, the drive will give you correspondingly increased support. If things are going easily, you hardly need the support, saving power. This means the battery discharges more slowly. This will extend your ride – and your riding enjoyment.
