Speedy DUO 2


The speedy Duo 2 "thinks and feels with you". Where there are mobility or route profile barriers for the pure handbiking, the built-in electric motor helps.


The results of the Speedy Duo 2 development give the handbiker powerful motor support and individual setting as needed. Thus, almost every rider can handle longer, uneven paths and steep ascents without hesitation or master everyday life with the least effort, even on days when you are not feeling so good.

The Speedy Duo 2 is based on the Speedy Bike. However, a pivotal additional feature of the speedy Duo 2 is the motor with torque control. With the Speedy Duo 2, the rider has a combination of two devices in one: when the motor is switched off it’s a normal handbike; when the motor is switched on it’s a handbike that supports muscle strength using an electric motor.

Motor support means that the power that the rider applies with the crank revolution is sensed using torque control and motor power is added – whenever necessary. The driver thus receives support from the first second onward, and from stationary position, when setting off in rough terrain or on a gradient. The power that needs to be applied to the crank handle to activate the motor can be determined by the driver themselves using the torque adjustment lever; and the setting can be changed at any time.

Motor torque control also means that support is automatically switched on or off during the journey. For example, when riding on level ground without motor support, the control responds by automatically switching on motor support, as soon as the terrain gets steeper. When riding with the motor on, as soon as rough, bumpy terrain changes to smooth asphalt, or a headwind changes to calm conditions, the control responds by switching the motor off.
