• Veleco mobility scooters

    From Harry Bloomfield Esq@21:1/5 to All on Tue Mar 18 10:12:26 2025
    I'm sure some of you, like me, rely upon a mobility scooter to get
    about. I recently bought myself a Class 3, Veleco Gravis, which I am
    absolutely delighted with. Wanting to be able to repair/maintain it
    myself - I then did a search, to see if there was any sort of forum, for support and exchange of information on these scooters, but all I could
    find was a Facebook forum, run by Veleco themselves, with any negative
    comments about the scooters filtered out, along with it seems any
    practical help to DIY. The company almost insist on their engineers
    doing all the work.

    Not happy with this far too tightly moderated, 'closed shop', I have
    just set up an alternative forum, where members can freely share any
    problems, help, and information.

    It's here - https://www.facebook.com/groups/1168046121135899

    Aside from the Polish company Veleco reselling this range, Green Power
    in the UK also sell them, so those owners will be equally welcome. The
    scooters are actually built in China. IMHO they are well designed, and
    well built.

    I have no personal experience with such machines, but often when something
    is imported from China it's possible to dig around on Alibaba and find the original manufacturer - either by recognising the design or by taking it apart and looking for clues internally. You may find they also offer components for sale which is a useful source of spares - for smaller items once you know what you're looking for they can sometimes be found on Aliexpress.

    With a bit more sleuthing you may also find other brands reselling the same models, which means you can share parts and repair information.

    For example, there's a popular knockoff of the Mirka Deros random orbital sander:
    https://www.youtube.com/watch?v=46Ws3Bgp_bA https://www.youtube.com/watch?v=jelEm54OLQw

    which I managed to track down the OEM as:
    https://burley.en.alibaba.com/

    They wouldn't sell me their sander in quantity 1 so I bought the Sealey one (not massively more once VAT and shipping from China was included), but
    parts for their models are available from Aliexpress, so I know where to go to get sanding pads, PCBs etc in future.

    Google Lens is useful for finding rebadge model numbers/ knock-offs for
    spare parts,technical info etc

    That's handy. It looks like many parts are from the Chinese e-bike
    ecosystem, so it shouldn't be difficult to find similar if not identical
    parts. Unlike Western e-bikes it's a pretty open ecosystem - rather than
    using software, communication is often with switches and basic DC voltages
    so you can easily swap out one electrical part for another.

    (in China, there's no hard distinction between pedal e-bike and moped, so
    often the chunkier ebikes are built like mopeds. Once you have an electric moped you can use many of the same parts to make a mobility scooter)

    Given the publicity that dodgy E-bike fires are receiving at the moment,
    maybe the DIY approach isn’t the best.

    My suspicion is that a good chunk of dodgy ebike fires are down to
    mismatched chargers. Many of them use a standard barrel jack, but if you
    plug a charger for a 48V battery into a 36V battery, it'll overcharge the
    cells and cause fireworks. The chargers are typically simple
    constant-voltage constant-current power supplies and the protection is in
    the BMS in the battery. But if you overvolt the BMS you may fry it enough
    to not be able to shut down safely, and then you overcharge the cells and
    they explode.

    In the kind of places where there are fires there may be multiple e-bikes
    (eg the garages for blocks of flats where several people live who do food delivery) and it would be very easy to plug in the wrong charger. Really we need a bit more smarts to prevent that happening. It's not a problem if you own exactly one battery and use the charger that was shipped with it.

    While there are some DIY e-bike builders who are obsessive about balancing
    and reckon (foolishly) they can live without a BMS, I've not seen anything problematic in commercial e-bikes. Not that I've seen them all of course,
    nor analysed failure modes, but from what I've seen 'dodgy e-bikes' seems to
    be a meme that doesn't actually a root cause analysis as to why they are
    dodgy and how they fail.

    There is a UK version of that ebay site, parts seem not to be a problem.
