I recently bought a Carrera Vengeance ebike on the understanding given by sales and internet information that I could achieve 40 miles plus from a fully charged battery this is not the case and feel so let down with the product as these pointers where the reason I purchased the bike in the first place the most I’ve managed to achieve is 26.3 miles which is far less than is advertised by Halfords the only way 40 plus could be achieved is with a back up battery of which is not offered so as you can tell I am not very happy and feel I have been given false information of which I will look into if I’m not offered a resolve thank you
