At Eurobike, TOUR was already able to take an exclusive look at the new iAerolight from BH Bikes, and now the Basque manufacturer is presenting the motorised competition racer to the world public. The unusual concept comes with a specially developed motor and is designed to cover up to 180 kilometres.

E-road bikes sometimes have a difficult time. As the typical speeds on the road are usually above 25 km/h and therefore above the maximum permitted speed, motorised racing bikes are still a niche product despite the e-boom. BH Bikes shows courage with the new iAerolight and gives its aerodynamic competition racer a mid-motor.

The second generation of the BH 2EXMAG delivers 250 watts with a maximum torque of 65 Newton metres. With the battery integrated into the down tube, the Basque bike manufacturer promises a maximum range of 130 kilometres. With an additional battery, which is inserted into the bottle cage on the seat tube, up to 180 kilometres should be possible. The four support levels can be selected via an integrated button on the stem. The riding modes can be customised via an app.

By way of comparison, the HPR50 engine from the Bavarian manufacturer TQ, which is used in the Pinarello Nytro E The Mahle X-20, which Rose has installed, delivers a maximum torque of 50 Newton metres and can travel up to 100 kilometres. The Mahle X-20, which Rose Reveal Plus provides support over the same distance with a maximum of 55 Newton metres.
