All very baffling! Do these light weight bikes have decent fork suspension? Even though our forks are cased in magnesium, they add a few kg especially when we add the suspension seat post. All the components on the latest Wisper bikes are aluminium with a few parts in stainless steel. Tyres...

Be carful when comparing weights, a powerful battery can add more than four kilos and there is no rule on whether a bike should be weighed with or without battery and accessories. A fully laden Wisper 905SEL 37V 11Ah is 25.4kg but a 37V 16Ah is 26.3kg. Without battery the same bikes weigh...

Hi Oiseaux, the first lot have just arrived but these are all sold, the next batch will arrive at the end of June. All the best David

I agree Flecc, the bikes are simply different. My suggestion for anyone who is undecided is to try them both. All the best David

Thanks for the clarification Andy, the wheel spin was only a problem when the throttle was being used during start up. Under pedelec only mode the motor comes in now before one revolution. All the best David

Hi Celedep The whole LiFePo4 question is very interesting, we have been testing them off and on for years. We still have two major problems, weight and volume. We tend to go for high quality, high power light weight batteries as this has become a bit of a trade mark for Wisper over the...

In our opinion it is a huge issue NRG, we have been working on it for a while now. The new Japanese Dapu system used on DaaHub, Alpinos and SELs though expensive has no perceivable drag. I think most decent manufacturers of hub drives take drag very seriously. It is important, as many choose...

Love the basket Morag, and the Dog! Please may I have the supplier detail? (for the Basket! :)) Best regards David

Yep, that's the one! All the best John! David

I thought most bikes now had a soft start program that brings in the power over a second or so to avoid wheelies? We have had to put them into our controllers for the three highest power settings. All the best David

There is another variable that does not get much attention. I have just finished negotiation with our battery supplier with respect to warranties. Wisper gets a 30 month warranty, with a 20% maximum drop in voltage after 2 years so we can confidently pass on a 24 month warranty with a...

We have recently had a report form an Alpino rider who has achieved 80 miles from a charge with Volts left in the tank, where as I only get about 30. Ranges are so difficult to pin down and so much depend on so many variables! All the best David

Hi John, welcome to the Forum and thanks for choosing a Wisper! Do you have the Wisper 705 350W, if only we could sell them here! All the best David

Hi Graeme, I too could make a sales pitch to you, however I would simply ask you to try both bikes. Wisper Dundee in Dundonald Street have sold many Alpino's so you would be in good company. They are locally available to look after your free safety check and servicing for years to come...

Hi John Mike Clyde (Wisper main deler Canada) uses an analyst that is made in Canada, I have just ordered four of them two for UK and two for testing at the factory. If you would like to give me your email address dmiall@me.com I would be happy to send your details to him. Best regards...

Hi 289, I thought your test sounded fine! I am surprised it didn't work! I am delighted to read that there is absolutely no drag on the motor. The motor we use on the Alpino, SEL and DaaHub kit is a very fine example of Japanese engineering and one of the reasons we use it is due to the 0...

Put them to the test Ed! But your Pizza may be cold! All the best David

Hi 289, thanks for agreeing to do the test and great idea re your test I will try my bike this afternoon. Yes the 706 and 906 wiring is identical, and it is safe to turn off power whist riding. No problems re reply, just keen to get to the bottom of the issue! All the best David

That's great news! The new 15.4 and now 16Ah batteries are returning great ranges and although electric bikes are heavy at 24/5kg the drag on the Alpino motor is now so small it can hardly be felt. As I mentioned earlier in this thread I simply can't feel it on my bike. I am delighted you...

Thanks Jerry, we should be seeing a few more Dominos following suit. All the best David
