After years of product conceptualisation and design development we welcome the first ORRO electric bike into their Terra family. Early in the design process the ORRO bike team homed in on gravel riding as the basis for electric development. The aim was to enable everyday cyclists with the ability to take on more mileage and make it easier to tackle tough off-road climbs, such as those in the native South Downs testing ground. Terra E marks a considered entry from ORRO into the empowering world of lightweight electrically assisted bikes.
Seamless Design
Terra E has an integrated design and user experience. Each of the five colour coded power modes are easily selected while riding using a backlit button on the top tube. The clean lines of this lightweight carbon fibre gravel bike belie its electrified nature. A svelte down tube hides the 250-Wh battery of the FSA System HM1. And, with an optional range extender cell which is carried in a bottle cage, the capacity for power can be doubled. A mobile application wirelessly interacts with the system, adding the ability for riders to review battery performance and customise the settings.
Integrated Electric System
In developing a hub motor driven e-bike ORRO have been able to keep the horizontal distance between the pedals, known as 'Q Factor', the same as typical non-electric bikes. This gives Terra E a riding stance and pedalling characteristics that will feel familiar to all cyclists. The frame is designed from the ground up for System HM1 motor and battery units. These components can deliver a maximum 42Nm of torque and a range of around 50 miles. Integrated torque and speed sensors provide natural feeling assistance across each power setting. Complete system weight is 3.98Kg.
