    Electric Canal Boats…the perfect EV ?

    BYD Seagull, the cheap electric car the USA almost got

    Most BYD vehicles seem to double in price as soon as they leave China ,….and that is before any tarrifs or taxes ! With no “tarrif” the proposed price in Australoa is reported to be $31,000 Au , and undoubtedly that would be for the 30 kWh base spec model before sales tax etc. ..whilst i...

    1 Group has more voltage sag

    Hmm ?, it certainly seems that you may have one or more bad cells in that group, which can only get worse ! What warranty came with the battery ?..at only 16 months you should not be seeing this type of issue, ..BUT,..20,000 km must mean how many charge cycles ?.. that may invalidate any...

    Just use a decent bike trailer behind an Ebike. ,! or a commercial cargo Ebike ( how much cargo do you need to carry ?) Why do you need a “tilting” 3 wheel design when you already have that feature on a 2 wheel bicycle ? The carver need to tilt because of the higher speeds it is designed for...
