Technology

Gearbox

Our gearbox technology eliminates rear wheel gearing. Hardened steel spur gears are protected from the elements within a sealed, lubricated enclosure. Our patent-pending sequential gear change mechanism uses an electric actuator for rapid and consistent shifting performance. Our custom control algorithms ensure a smooth shift every time.

Motor

Our proprietary motor technology is fully integrated with the gearbox, forming a single compact drive unit. Our novel reduction gearing arrangement enables a high torque output, with a very small footprint. Power is then transferred to the rear wheel via a belt or heavy duty chain.



Applications



Mountain

  • Low maintenance - all gears are enclosed away from the elements. Extremely resilient against mud, grit, dust, snow and sand, and as a result hard wearing.
  • Low unsprung mass resulting in improved suspension performance.
  • Wide 480% gear range provides the capability to ride all kinds of terrain.
  • Straight chain line, resulting in less chain wear and longer chain life!
  • No dropped chains. All the benefits of singlespeed but with 8 gears and a motor!
  • No exposed dérailleurs, delicate hangers or brittle cassettes. Less parts susceptible to external damage.
  • Fast & consistent gear shifting, throughout the life of the bike


City

  • Low maintenance - minimal drivetrain cleaning required
  • Fleet bike schemes can benefit from low OPEX.
  • Straight chain line, resulting in less chain wear & longer chain life!
  • Optional silent belt drive, lightweight and clean (no lube/degreaser required).
  • Change gears when stationary and shift multiple gears in one go!
  • Even steps between every gear, making gear changes very predictable.



Last Mile

  • Low OPEX through low maintenance.
  • Transmission designed for higher loads than dérailleur gearing - perfect for hauling heavy cargo.
  • Change gears without pedalling – a particularly handy feature for a loaded cargo bike. Select the best gear before taking off at the traffic lights, or select the appropriate gear for starting on an incline.
  • Smart shifting for the right gear at the right time. No need to train fleet staff in the operation of gear shifting and prevent damage or premature maintenance of the fleet.
  • Reduce fleet greenhouse gas emissions and air pollution by switching to E-Cargo Bikes.
