Powerful electrical assist
All HP Velotechnik bicycles and tricycles can be optionally equipped with the powerful and efficient
electrical assist systems, either from
GO SwissDrive or the
STEPS e-drive from Shimano.
Both systems provide support up to a speed of 25 km/h / 15 mph (in the US: 32 km/h / 20 mph)
as well as a start assist up to 6 km/h / 3.5 mph forwards. The GO SwissDrive option furthermore offers
a 3 km/h / 1.8 mph backwards throttle and, especially for users with special needs, the system software can be
customised to low pedalling forces or unbalanced leg power which is shown in the following graphs:
With the start power option, the system support with higher torque on lower pedalling forces.
This helps weaker people to reach their favored speed and climb easily.
With the code "interval" a smooth assist upon unbalanced cadence is being improved.
