wisper 905se

[flecc]

If you do find you'd like the top gear a little higher Frank, the 13 to 34 is readily available at £9.99 each, it's the one I use on my Q and T bikes.

Wiggle normally have them and have one in stock at the moment on this link.

Thanks Flecc,

I'm actually going to order one of those very soon for the kit bike that I am planning to assemble as my Christmas project!

A good run across flat West London to my office will tell me what I need to know about the Wisper's gearing. Like you, I was surprised not to see one of these on there already as it partially negates the objective of the big 52-tooth chainwheel.

You, as always, are absolutly correct Flecc!

However the new 905 range available in early 2008 does not share one component with the original 905e apart from the wheel rims!

Best regards David

A gentleman based at the Sammy Miller Motorcycle Museum, phoned me two days ago offering me one of the remaining original 905e bikes. He said that they were "virtually the same" as the new one and I'd be saving £150 compared to the new model. They had apparently been ordered by the police who had since opted for the new 905se instead.

Salesmen! Don't you just love the way they bend with the wind, changing the message according to the stock!

One reason I'm so interested in Frank's experiences is the extreme reluctance of Wisper to get one of their bikes reviewed. I tried to get them to send a 905e to A to B very many months ago, and when that didn't happen, I encouraged the same for the 905se, but we're still waiting.

I was offered a trial on the 905e, but as I said in another post, I prefer to remain impartial and not test, the Kalhoff being an exception due to it's status in respect of my Lafree support website.

Hi Guys

Just a quick not to keep you up to date.

Firstly sorry about our over enthusiastic salesman, Doug has had a word! We have a few demo models of the original 905e left in stock and although they look like the newer models there have been many changes, hence the lower price.

Please forgive me for using the forum as a sounding post but I find your comments extremely useful and believe me you have all been very instrumental in molding the new range.

The new range of 3 x 905's and the 705 will be here in the UK in March 2008, I am at the factory again in early January to sign them off for mass production.

These bikes will be ready to send to David Henshaw at A to B for testing.

The bikes sent to Germany were not the final specification, we were reluctant to send them but our German partner was very keen to get some in for the summer exhibitions.

The German bikes, for legal reasons were not sent with the the throttle or buttons installed. The UK bikes will have Throttle, on off and de-restrict buttons, mudguards, and rack already fitted, so the set up time for the bike will be dramatically reduced. All you will have to do is fit the handle bars, front quick release wheel and peddles (tools will be included) and you're off.

Among many improvements the rear caliper brakes have been upgraded and the front discs are now Shimano. We are currently sourcing a hinged seat as we agree with Franks comments. We are also still considering the size of the small cog on the rear wheel, 11 tooth seems a tad extrema but we would be interested in your comments Frank.

The computer has also been changed to one that is more easily readable and has a back light for night riding.

The final spec and price list for the 905 range and the 705 will be ready in early January but these are the basic specs at the moment. Any comments or suggestions would be welcome.

Apart from the specs shown below all other items are the same on all models

905se Sport

14a 36v Lithium Polymer battery, 250w motor, front suspension, saddle suspension, front disc brake, sport mudguards, pump, bottle holder, 7 gears. De-restrict and power on / off buttons on handle bars.

905se City

14a 36v Lithium Polymer battery, 250w motor, saddle suspension, (no front suspension) caliper brakes, full PC mudguards, pump, bottle holder, 7 gears, front hub dynamo lighting, rear rack. De-restrict and power on / off buttons on handle bars.

905

8a 36v Lithium Ion (Manganese) battery, 250w motor, one gear, no suspension, caliper brakes, no mudguards, no rack etc.

705e City

8a 36v Lithium Ion (Manganese) battery, 250w motor, saddle suspension, (no front suspension) caliper brakes, full PC mudguards, pump, bottle holder, 7 gears, front hub dynamo lighting, rear rack. De-restrict and power on / off buttons on handle bars.

Thanks for the updates David. I can understand you not wanting to send a bike short of the final spec for review, but really look forward to an independent view on the bike.

11 tooth sprockets are a bit extreme as they wear fast, the tight chain radius also being rather inefficient. On the other hand, Shimano's 7 speed freewheel incorporating an 11 tooth top is a stronger product with better bearings. On a 6 speed like Shimano's Cadet freewheel, the 13 tooth top sprocket is a better choice on wear and efficiency grounds.

Thanks for that Flecc, yes we agree a 13 tooth top sprocket will be best.

Frank another point worth mentioning is the motor from Germany is only 200w and the bike does NOT have quick release front wheel.

Also the comment regarding 905 was correct at the time of asking but we have now amended the specs.

Best regards David

 

[frank9755]

David,

Really? The ebay listing said it was 250W...

Frank

 

[Cyclezee]

I must correct the previous post. The 905se from Germany does have the 13amp battery and the 250w motor not 200w, it is clearly printed on the motor.

John

 

[frank9755]

I've just checked the motor on mine and it says 250W too.
But David should know...!

David, regarding quick release front wheel - if you are thinking of putting one on, you might want to read this first

Exactly Frank, David should know! I have sent you a PM regarding this.

John

 

[Wisper Bikes]

How embarassing!

Yes they are 250w! Standard for Germany not the UK bike.............. oooops!

Thanks for the tip on QR front wheel Frank! We will make the amendment straight away.

Best regards David

 

[frank9755]

That's a pleasure - we don't want any nasty accidents showing up on You-Tube do we!

Now, David, what exactly do all those red and green buttons do? No-one seems to be able to tell me! In particular, which ones would I press if I wanted to go as fast as possible?

Thanks

Frank

 

[BossBob]

LOL

I like that !!

Cheered me up no end after a pretty poor day

Superb!
No, really

Still laffin ......

 

[flecc]

Frank, I'd say press all the green ones and shut your eyes, but whatever you do then, don't forget where the red ones are.
.

 

[frank9755]

If only it were so simple!

I suppose that at least continues the trend for each person to have a different answer for what these mysterious buttons do!

 

[frank9755]

I think I've got it.

If anyone else is confused (and they are!), my understanding is that the red one on the right seems to enable the throttle, the green one on the left derestricts and the red one on the left restricts speed.

The pedelec operation only seems to operate up to the restricted speed.

So, to go fast, you press the red one on the right, then the green one on the left, then twist the throttle!

Frank

 

[Wisper Bikes]

Buttons buttons everywhere!

Hi Frank

You will be delighted to know that the new model only has two buttons one on the left and the the other, you guessed it, is on the right. The right hand button will turn the power on/off and the left de-restrict on/off, however.....

On the model you have the right hand button turns the throttle on/off, the right hand green button turns the de-restrict on/off and the red button turns the power on/off.

If you push them all at once it operates the ejector saddle, so beware!

Best regards David

 

[frank9755]

Thanks David,

I think I scored 1.5 out of three on that test!

Am I right that the de-restrict only works with the throttle, not pedelec? I'm trying to get another mark to get above 50%!

German bikes 250W/UK200W? Ebay

Yes they are 250w! Standard for Germany not the UK bike.............. oooops!

Best regards David

So that means the 250W is only on the 905SE/Germany,
and 905SE/UK only has 200W?

By the way - they are on Ebay again: 330196847924
