UPDATE! Further to the frequent spoke breakage problem I can report that Wisper and their excellent after sales service, suggested they rebuild the wheel! So with a 1 week turnaround and at no cost to me they have fitted a new rim, spokes and nipples assembled with Spoke Freeze which I am assured will cure the problem. Time will tell. Given that the bike is well over 3 years old I am well impressed with Wisper.

Hello, long time no post, this time I have a major problem with rear wheel spokes breaking on my 705. I am now on my 8th! They started breaking after 18 months from new. Wisper were very good at sending out replacements while under warranty for me to have fitted locally by my excellent local bike shop (Cranked Bikes, Victoria, Cornwall). However it does usually happen when I am miles from home and on tour, so very inconvenient. Twice the broken spoke has caught the derailleur gear flipping it up and locking the wheel so potentially very dangerous. The last time was on the steep hill out of Coverack down on the Lizard with the motor and me on full assist. It is clearly due to the high torque required. Another bike shop locally said it is common on Wispers. In spite of the problems I have had with my 705, squeaky brakes changed to Shimano and electrics faulty connection in the battery control unit, actually I do like it! Wisper have told me the wheels are machine assembled, which they informed me is not ideal!! So what to do? Any suggestions please for a long term fix.

Hi Wisper owners. Another electrical fault, this time on my wife's bike, which I thought may be of use to anyone with the same fault. The charger connection has been intermittent for awhile now and yesterday the only way to make it work was to pull slightly on the cable and plug and hold it like that. So I suspected a poor connection behind the socket and sure enough that was what I found after taking the battery cover apart, see photos. I had to remove the sealant which had set hard, which was the most difficult part, and then tighten up the lock nut which grips the -ve connection tag. All is well now!

After much searching I found the discs for the Avid DB1 DB3 and DB5 fit the Wisper 705 calipers and are available on Ebay here. They seem good quality and price and sent first class. The Wisper pads are 29.8mm wide and Shimano etc are 30.8 and do not fit!

Wisper fault update. New control box from Wisper fitted, cut off the bullet connectors and fitted MT60 3 pole 30 amp gold plated connector available here (thanks Nealh). Big difference, more power and no stoppages, 20 mile trip with some serious Cornish hills and no problems. Incidentally the clicking sound on each rev of the crank also solved by tightening the pedals with spanner and long pipe for extra leverage. Thanks for the help folks!

Thanks David, great support as always.

Nealh, thanks for that recommendation great idea if they will fit in with all the cables otherwise I would solder and heat shrink. Problem before was it was all stuffed in the small space and the control box must get quite warm so very little air circulation. With Wispers legendary support service I hope to have it fixed soon and get up those hills round here!

Thankyou David, I have done that and sent the attached photos which I believe show the fault. I took the cover off the control unit to reveal a narrowly missed potential fire! I have to say I was disappointed to say the least at the quality of the electronic connections in that tiny compartment on an expensive bike. I await a reply from Adrian

As I said it is fully together, simples!

Thank you for the speedy response. I have made sure the connector has not come apart at all but it is a major job disconnecting and electrolubing it, see attached. And its under warranty. I am surprised the connector is in such a vulnerable inaccessible place!

Hi all I am new here and am well impressed by this forum. I bought 2 new Wisper 705SEs at the end of last year for my wife and myself. They were bought online many miles from our Cornwall home, major mistake as warranty repairs have to be done by supplier!! In general they are great but we have had some niggley faults. The first showed up almost immediately on both bikes, that of squeaky noisy brakes. Nothing I could do would cure it so Wisper very efficiently sent out 2 sets of new different discs and pads, which I fitted, and they have cured the problem. It does beg the question why were the bike manufactured with naff brakes? After 550 miles now I have a problem with the intermittent sudden loss of power on one of the bikes which was cured by switching all off and on again. However yesterday the reswitching failed to work but when I twisted the hand throttle there was a grinding strange noise from the control box in front of the battery. I was contemplating a long hilly ride home but when I applied the front brake lever power was restored and I got home. Now was that just a coincidence or is there a linkup? If there is a fault with the control box I have the job of packing it up and sending it back to the online supplier. I am quite capable of fixing things, I changed all the discs and pads so is it a big job fitting a new control box assuming Wisper would supply me with one? Incidentally I attach a photo showing the bikes with the Topeak Trunk Bag DXPs. They are the model that does not have the combined track mounting which will not fit the Wisper carrier so they are attached with the velcro tabs backed up with cable ties. We modified the fold down panniers to clip into the Wisper luggage strap fastenings on the frame. Looking forward to hearing from someone!
