David, yes that was me. I took a chance and sent it to the email address in an earlier post. It wasn't current but I got the auto reply with the correct email. Thanks

I have a similar problem. Are the above contact details still good?

Thanks David. I would like to say how impressed I am with the response of Wisper to issues raised. I have experienced this myself and have seen it for others on the forum. I am delighted with my 905, and although I have had a couple of problems, Wisper have always been ready and willing to...

No, I've never dropped the bike. And anyway, it has a guard fitted to protect the derailleur which by consequence would have protected this electrical cable. To be honest I have no idea. It could have been like it since the day I bought the bike for all I know, as this is the first time I have...

Well I have carefully put the cable back together and put extra heatsink around it. Also I have moved the connector around under the controller so I have more slack in the cable to the rear hub. This means the cable can now come straight out of the hub spindle without being strained on the sharp...

It took me a few seconds to understand why that would make any difference. I guess you thought it was a front hub? It is a rear one.

Yes I have contacted Norman. He says that realistically I would need a new motor. I bought my bike from Bristol (atmosphere bikes)

Ok, I'll contact him. Thanks. I bought my bike about 6 months ago

Thanks for the advice. I expect the photo makes it look like these are the thick wires but they are the thin ones (which you say are for sensors) Any idea what this thin red wire does? I guess it is bad that it is broken as it must serve a purpose.

Here is a photo to explain better

I took off my back wheel today to replace the tyre and noticed a problem with the motor cable where it enters the spindle. On the freewheel side (where the cable goes in) I removed the rubber boot from the spindle nut and there is a sort of spring/coil thing on the outside of the cable (to...

This just happened to me as well. Rear tyre, sudden blowout. :(

Well I got to 30 miles and it still had not run out completely. However it was becoming a bit gutless so I am now charging for next week. It seems that I was putting too much emphasis on the indication lights when the motor was active. I don't think it is very clear. When I see a red light with...

Thanks for all the responses and advice everyone. I have bitten the bullet and am in the middle of a distance test where I am going to ride until it is completely flat (even if I have to cycle all on my own to get home) I will post again with my results.

Is this the serial number? (can be seen in attached photo) 260240A0-002 B/E 0015 Second photo shows label on side of battery. Curiously it says 36v when everything I read on the website says they are 37v

Thanks for the feedback. a) Yes, this is a concern. Where is there serial number located on the battery? b) Agreed. I have nothing more to say on this! :-) c) Very little starting/stoping involved. I am definatly putting in input myself.

The point (at least on Wisper bikes) is that they have pedal assist which is independent from the throttle.

I don't use the throttle. 40 ish is more like I'd expect and be happy with. I'd be grateful to get anyone elses experience?

Both on rear wheel. I guess I'll contact the retailer. I do have warranty but didn't really think of it for a couple of spokes which cost pence (well they did last time I bought some) (also the retailer isn't exactly local. Hopefully they'll post them)

I have two broken spokes and have tried LBS and Halfords for spares with no luck. Are these 'special' spokes? Or was I just unlucky and should try more local bike shops?
