    Hello!

    I much prefer my bikes not attracting thieves. Also, we sell mainly to the young at heart with feeble legs. There is only a Woosh logo on the head tube and an EN15194 sticker with our name on it. It does not say I am electric and expensive. we can fit any saddle that you see on another of our...

    Hello!

    she should be OK with the Rambla. It has 5 assist levels and 100NM max at the chainring. Trading torque for revs. At her weight, she should be able to climb pretty steep hills at that sort of revs but still has to change down to gear 3. It has a revoshift so changing gears is pretty quick and...

    Hello!

    it was first on sale before the lockdown and sold out more quickly than we expected. My guess it was due to the Covid effect. The next batch arrives end of August.

    the new Rio MTB's fork: with straight steerer tube.

    Hello!

    seems to me that a Woosh Rambla would suit her well: https://wooshbikes.co.uk/?rambla The bike is very quiet and feels very much like riding a good push bike. The battery is 36V 14AH, she should be able to get 50 miles out of it at her weight.

    Cobalt-free battery leans on nickel for extra energy storage

    I think that the Cobalt question hits the news because of Tesla's deal with the Chinese. Elon Musk attracts so much media attention so journalists amplify anything he said. However, the gist of the deal with the Chinese is to replace cylindrical cells with cheaper prismatic cells - apparently...

    Cobalt-free battery leans on nickel for extra energy storage

    there are a few well proven recipes for Lithium batteries' cathodes without Cobalt like Lithium Iron Phosphate (LFP for LiFePO4), Lithium Nickel Manganese Oxide (LNMO). Tesla is doing a megadeal with Chinese CATL to get their LFP batteries into their cars. Cobalt is used in batteries for...

    Folding ebike - ideally sub £1k

    First week in September. If you intend to pull the folded bike, you will need a bungee cord to keep the folded bike folded. For pulling on a flat surface, you can balance the folded Rambletta on one of its wheels and pull by the saddle because its wheels are not parallel when folded. That's...

    Rear hub questions wooshbikes

    yes, very much so. It's an awesome motor. I use the DWG22C on the new Gran Camino (at sea at the moment).

    The follow on to Power MOSFETs, will most likely be:- "Insulated Gate Bipolar Transistors (IGBTs)

    let's just leave the personality and writing style out of this thread. Andy-Mat started the thread in a perfectly civil manner. Although I disagreed with him about the future of IGBTs in e-bikes, we could still wish one another a good weekend.

    Rear hub questions wooshbikes

    you will need to decide to buy in the UK or abroad. If you buy abroad, the support will likely to come from the forum. Even with the best help from members, I don't think it can compare with direct support from a UK company. You will also have to decide if you want to buy from one source or...

    Recommended ebike not for commuting

    if we still have stock, then it can go out to you the same day by Tuffnells. Best talk to Hatti (01702) 435566.

    Recommended ebike not for commuting

    yes. The piston inside the fluid reservoir has a magnet, the sensor is at the end of a tube parallel to the piston that you see in this picture. The sensor is adjusted with a 7mm wrench. I have now amended the links on the web page, thank you for pointing it out. Bike manual...

    length of lockdown?

    the issue is what our government does to protect the 99.9% of the population. So far, the economic cost runs over £300 billions. It can't afford to spend that much going forward until treatments and vaccines are found. I guess we'll see local lockdowns replacing nationwide lockdown but as long...

    the cells in the 17AH battery in the Rio MTB are Panasonic 3400mAH NCR 18650B. it's lasered into the case. edit the 17.5AH HL battery is made with Samsung 35E. it's difficult to keep the information up to date with so many shipments.

    The follow on to Power MOSFETs, will most likely be:- "Insulated Gate Bipolar Transistors (IGBTs)

    your wattmeter sits between the battery and the storage capacitor. The frequency of the current flowing through it is very small, it may have ripples but the ripples wouldn't be strong enough to create a noticeable impedance due to the coiling. The shunt sits right after the legs of the MOSFETs...

    length of lockdown?

    true but we are here - if you are tested positive by our NHS, what do you think your chances are? 0.5% like in Germany or 15% like in the UK? By the way, someone told me that because they swab your nose and your throat, our government counts it as two tests. I wonder why we don't have statistics...
