Circe – Helios Electric Steps Complete Tandem

The Helios is now available with the highly regarded Shimano STEPS electric assist. The STEPS motor is neatly fitted to the captains BB with the 11 Ah battery mounted to the downtube.

The system is fully integrated with the 8 speed Alfine hub gear, with the option to have an automatic shifting set by the press of a button. To make sure you can contain that extra power, the Helios STEPS is fitted with Shimano hydraulic disc brakes.

Propelling yourself using your own power is the very essence of cycling. Our load carriers and tandems are designed to transport combinations of luggage and riders that may just require additional help to achieve satisfactory propulsion. An electric assist can provide those much needed extra Watts, that might be the difference between effortless propulsion or perspiration inducing slog.
