    Fold up Bikes

    IMO, you are better off taking the balance of the advice given here than opting out and only buying what you can try out pre purchase. Any initial "test" of an ebike will be seductive, making a buying selection based on just that unsound, if into the testing you really need to try several...

    Dummies Guide to eBikes ...

    If my experience is typical then as with most things technical a "Dummies" guide only goes so far in upping one's understanding, typically only being of relevance as a reference after you encounter an "issue".

    Charging an ebike from a leisure battery?

    Again, no great surprise it is all about "energy", your 90 Ah battery holds, well did when the factory tested a sample, 1080 Watt hour, and typically can offer about half of that before getting into seriously damaging territory. [A few years in and probably holding just a fraction of its once...

    Charging an ebike from a leisure battery?

    Something like this kit makes a bit of sense. An evening in the pub probably more. If you are camping near, the Carpenter's Arms at Bransgore do excellent meals with homemade pies, enough energy in those to pedal unassisted a fair way over the Forest.

    Charging an ebike from a leisure battery?

    On exceptionally good days a 10 Watt will get 6 hours of high yield, so that will give you at best, 60 Watt hours of energy. [You will be off cycling or otherwise not there to optimise tracking the sun.] Your 17 Ah 36 volt battery at best stores 17x 36= 612 watts hours. So with 100% efficient...

    Can you fit an after market battery to a bosch equipped bike

    Surely that is to facilitate their further exploitation of their main income stream, their clients?;)

    Walking and biking prioritised in new Highway Code

    Compliance with what we have, seems to be the better target than a rewrite of rules that similarly will not be complied with and as likely bring no "real" penalty or incentive.

    New to e bikes .chargeing question

    Are EV rapid chargers outputting European mains voltages and frequencies to even power the e-bikes mains charger? Genuine question, as I have presently no idea what the standard interface voltage and or frequencies are, and just surprised with Tesla being a big player in EVs, the European mains...

    New to e bikes .chargeing question

    But if carrying your charger you can exploit such charging options as coffee, tea shops and many pubs like Wetherspoons, those that typically offer laptop charging.

    E-bike sales boom despite high prices and confusing rules (and confusing BBC articles)

    Personally, I did not find it confusing in the author was clear enough in being specific where they were writing about. How much value it would be to prospective UK e bike users probably was no part of the writer intensions, but then did it need to be, along with much that is written on foreign...

    General Advice for Bike Choice When Doing a Conversion

    My comment however was very specifically about low speed and when not being ridden.

    General Advice for Bike Choice When Doing a Conversion

    One factor is handling the bike, at low speeds and when not being ridden, and both of these are affected by their centre of gravity, the higher the more negative.

    Rider weight and electric bike performance

    Council recycling centre bike access

    In Covid 19 restriction times, our Hampshire Household Waste Disposal Centres have adopted an appointment based system, rigorously upheld. That arrangement I can understand the logic base. I book my slots on their web site, a bit tedious as popular times are just that "popular" and quickly...

    this is really a big problem. The electric motor touches the brake. Please advise.

    Is it not that the hub can't yet be fixed with the shaft nut, simply because it fouls the calliper on initial offering up? Frame spreading and inserting a spacer washer?

    So... How much should I Dremel this bottom bracket?

    Dare you work a tap in a little further, LINK ? Its lead in section, will bore, true and in line, only where the excess metal you need to ease away is.

    So... How much should I Dremel this bottom bracket?

    Is there any merit in using a cheap, electric drill driven cylinder hone? LINK I would add, it is not a task I have done, but just musing on how I might do it if I needed to. Identifying what needs Dremel attention, if going that route, would be something I would try to resolve before...

    Where are Wisper Bikes Manufactured?

    I feel both the terms "manufactured" and "build" imply far more than the reality of the situation, which surely in this industry is better described as "assembled"?

    Is there a universal mid mount motor standard going to be developed?

    I would like to think some level standardisation or various standards will happen, it has to a large extent in the components of bicycles, they even once standardised on threads.
