        Does what it says!

        Really brilliant bike so far! been using it for commuting, battery life is really good! Plus delivery was quick!

        Only one downside is the seat battery has to be take with you everywhere as its quick release and anyone can just walk along and take it but other than that amazing little bike!

        Brilliant D21 ebike

        Awesome bike, really pleased. Arrived the next day, perfect service from Vive Scooters!

        Outstanding D21 bike

        So far so good. Excellently built bike and a decent motor which gives plenty enough power to help you zip along. Pedalling is needed but the effort is taken away.
        Love the colour and design and the space saving from the folding functionality.
        Charged the battery once upon receiving the bike and haven’t had to charge it since.
        Great purchase!
