    Wisper DaaHub arrives - what a bike!

    Hi Vectra, there are two sets of silicone shims in the kit, one thicker pair for use on the seat post and a thinner pair for use on the seat post tube. All the best David

    Wisper DaaHub arrives - what a bike!

    No problems Kitchenman The charger weighs 1.2kg I will have an image for you on Monday. Hi Tillson, re the positioning of the DaaHub dock and battery, simplifying matters considerably, our aim was to get the weight of the battery as far underneath the rider and as low in the frame as...

    What a bike!

    Thanks Eddie It is rather special! Unfortunately I am going to have to sell it now as the new SELs are coming in and I need to have a latest demo bike. It is a few months old and has only done a few KM it has a brand new 15.4Ah battery. This is the last of the XCs, I should probably...

    National Electric Show type thing

    I organised and put on The Sustainability Show at the O2 in London four years ago, it took many months of organisation and cost me personally many tens of thousands of £ to put on but that is normal for a first show. The Sustainability Show at The O2 on October 26th, 27th, 28th 2007 The...

    Wisper DaaHub arrives - what a bike!

    And how Oiseaux! I have 2 on the way to the UK for testing, you simply drop out the 15.5mph wheel from an Alpino or DaaHub and fit the 30mph one, I think we can use the same controller, but it would need to be switched from 15.5 to 30. We can only get a 1 year warranty at the moment but are...

    Wisper DaaHub arrives - what a bike!

    Hi NRG, I feel you should maybe try out the DaaHub Dock, mounting system before you condemn it? It is absolutely superb, the battery and mount work so well together it is absolutely amazing, not a rattle to be heard even over rough terrain and so easy to remove and re-install the battery. It...

    Wisper DaaHub arrives - what a bike!

    Thanks Andrew, this is why we chose function over form, although as I say if people prefer the more standard look the superb DaaHub Dock mounting system will enable the battery to be mounted at the back off the seat post. Which is so much more sensible and beneficial to riding characteristics...

    Wisper DaaHub arrives - what a bike!

    Absolutely no problems at al Tim. We have been hammering our test motors now for over a year, getting them to do things that they certainly were not intended for including long climbs at very high current, fast rough descents and high drop offs and we have not had a problem. Next year with the...

    Wisper DaaHub arrives - what a bike!

    Last point re battery positioning. To balance an electric bike it is important to get the weight of the battery as far under the rider as possible. The higher and further back a battery is fitted the worse the bike handles, hence the positioning of batteries on the vast majority of serious...

    Wisper DaaHub arrives - what a bike!

    That's a shame Vectra, do you prefer the seat post position? As soon as I have had a definitive answer from Dapu I will let you know, unfortunately Dick Lai my manager who deals with Dapu is away due to death in his family, but as soon as he get's back next week I will make sure you get your...

    Wisper DaaHub arrives - what a bike!

    Hi Jimod, I am with you, however Anthony and his nutty friends Love off-roading and the ability to chuck their bikes about without the encumbrance of a battery on the frame. TBH when I tried it out for the first time I was seriously surprised at the difference having your battery on your back...

    Wisper DaaHub arrives - what a bike!

    I forgot to say but the 370Wh battery does take up a bit of room and necessitates the brick like looks but it does pack a huge punch and I personally felt it worth compromising aesthetics for added performance. This kit is very quick! Best regards David :)

    The bike can also be riden with the battery off without the need to remove the dock and if the owner wants to get back to his routs then simply unplug the front wheel and slip the original back in. The only difference to the bike handling would be the 1kg dock still attached. If owners are...

    Wisper DaaHub arrives - what a bike!

    Thanks everyone for your considered and constructive comments, I am absolutely delighted that DaaHub has caused a bit of a stir. We have been working in it for 2 years, I would have been so disappointed if it had been received with lack lustre! I understand it is not perfect for everyone and...
