Firstly - I apoligise for upsetting a few of you with my first remark which was supposed to be humour Then...

Don't all speak at once! Okay - I seem to have cured it, everything taken off except the torque sensing cassette - everything cleaned thoroughly and lubricated with a cycle chain ptfe spray and reassembled. A short 5 mile test ride and the noise seems to have gone. It's been there since March...

Thanks for the reply VFR400, I have probably mixed something up here - pedals are square taper and if you look at the left hand side it has a special tool fitting which to me looks about the same as the Octolink fitting. Its the bearings within this that there is a little play in

Proably a basic question but ... my chainwheel on my 905 torque has been making creaking sounds, the chain itself is fairly new so I took it off, cleaned it and examined the teeth which seemed to be ok. I put it back on but used an old biker trick of reversing it. Out on the road the clicking /...

Hmm - my 905 torque with the 575w battery goes up 1 in 3 hills with no problem and I am a lightweight 15 stone pensioner. Most hills I can get up with level 3 power and VERY rarely have to go to level 4 so I would say there is an issue with the bike as David suggests

My friend who recently bought a Yose rear hub motor asked them to confirm dimensions before purchase, they sent a PDF which confirmed 135mm but when it arrived it was several mm bigger and did not match the PDF in any way. Sorry Yose I think you are pulling the wool over purchasers eyes...

A friend of mine has just gone through this appaling problem with a Yose conversion. Their engineering drawings show 135mm but the spacing required is several mm more. We jacked the alloy frame apart and managed to fit the rear hub in and also managed to fit the disc with the anti rotation...

Thanks Phil for that - pads ordered

Thanks for the link JonathanM - Phil, if they do fit the 905 ok can you post and I'll get some for mine?

I also have a 905 torque but have the larger 575w battery. Its not unusual for me to go nearly 30 miles without dropping a bar but that doesn't mean it will do 120 miles as above its not linear and its not always the same either. Hills plus wind and it drops much quicker

I think the link should be ebikebatteries.co.uk

The battery I have is the 575w/h one, the biggest one is 700 w/h, the indicator bars don't really change at all except for an occasion where I am using max power up a steep hill for a fair distance where it will temporarly drop one bar for a short while. That doesn't happen very often where I...

I have the 905 Torque with the mid size battery. The display shows 4 'bars' or segments and has been pretty accurate it seems and bars drop as you would expect with distance travelled. Two bars come up at about 40 miles or so and I have only seen 1 bar a couple of times but that has appeared at...

For me its flashing lights front and rear, the small cheap rechargable ones for about £10. They last ages and are not too bright but show the bikes position well at some distance. After many years as a motorcyclist and not being seen with a headlamp on all the time I don't want to hear the...

Ooops - didn't spot May - and it's 2019, back to Specsavers for me I guess :-(

Where are you? it would help me if you were somewhere nearby and I guess others :)

Thaks for your advice David - I am very impressed with the bike over about 1000 miles so far, I am very pleased to find such a quick response from you and, I ordered a sidestand about 2pm the other day and it arrived first thing with the postie the following morning. Glad I chose Wisper :)

Just to clear up a point I made at the beginning. The advice to remove the battery if not used for 4 hours was contained in the W108 display manual not in the Wisper manual itself

Thanks guys for the advice, very helpful. David, photos sent as requested :)

Thanks for that 1 You have echoed my thoughts 2 Ditto :)
