With thousands of kilometers behind them, the HSD is back with an updated e-bike system, bigger battery and higher carrying capacity. You might not be able to have it all, but can very much have more.

With the advent of Bosch's new gen 3 "Smart System" the HSD gets an overhaul. Better smartphone connectivity with the Flow App, the ability to edit your ride modes, GPS tracking available with the Connect Module and an increased battery size of 545Wh. 75Nm of torque with the updated Performance Line Motor

Upgraded shimano Deore 10 speed gears for better shifting performance

Tested up to 180kg for the maximum total gross weight. 80kg carry capacity for the rear rack, allowing you to carry 1 x 80kg adult or 8 x 10kg dogs (we don't recommend carrying 8 dogs on the back of your HSD).
