Whistle B-Race A5.1 12V 2022 – E-Bike



The Whistle B-Race A5.1 is the new electric mountain bike with an Atala Am80 mid-motor and integrated 500W frame battery for an e-bike with a range of up to 190 km

For the first time, the Whistle brand (which we recall is owned by Atala) is associated with the Am80 e-bike mid-engine and 29″ inch wheel

A combination that will knock out the competition thanks to the performance of this electric mtb that boasts an integrated 500W battery, LCD display, Shimano 12-speed gearbox and lockable fork.
