  1. As you know I bought this wheel from you – the HUB 8EW. The supplied 2 inch tyre was unsatisfactory due to poor traction and bump absorption.

    With considerable difficulty and some modification to the hub I managed to fit a 2.5 inch tyre. This was better but the controller or the twist grip throttle were most unsatisfactory, doing nothing until half throttle and then coming in with a violent jerk. This was most alarming when using reverse.
    I regard the thumb throttle, which UU could not supply as much better. On a tricycle it is probably not necessary to have reverse, it’s better to have a freewheel so it can be wheeled around without the motor drag fighting you.

    UU motor was unable to supply a wider wheel to the suit desired 3.5 inch tyre, this could not be fitted to the narrow rim. UU was unable to suggest a suitable solution.

    I have rejected the UU HUB 8 EW.for a modified e bike bicycle hub fitted with a 3.50 X 6 inch tyre. Most satisfactory, but bigger than what I want for my lightweight folding “TravelTrike” design. Ideally I would fit a 3.50 X 4 inch tyre, no suitable wheel for this has yet been found.

  2. I am looking for a hub motor wheel for the front of my prototype lightweight disability tricycle. Can you supply it with built in controller, thumb throttle and 36 volt lithium ion 10 amp hour battery in a bicycle drink bottle style container with all appropriate fittings.
    The battery needs to be labelled to indicate the amount of lithium in it to satisfy airline safety requirements.
    Please provide a price delivered to Australia.
    Thank you ,

  6. Hi all. I am a newby here on the forum and am highly interested
    in finding innovative disability aids that helps to
    make disabled life more bearable.

    Have some of you checked out this great little travelling wheelchair that folds and unfolds in 5 seconds and is featherlight enough to take onto train and if so ,
    what do you reckon about it ?

    • Hi Danny, we do have a cooperator who makes quick folding electric wheelchairs. They are easy to take onto trian or plane.

  7. We need to e-bike kit, but the engine must be subject in one arm. I watched without a kit for e-.bike have this engine. However, I see that produce these types of engines. Could you put together a kit for e-bike that includes a motor for holding one arm?

    We need it rather urgently.

    We welcome your comments

    regards

    Best Regards,

    Alessandro Bergamini
