Got my Wisper 905SE

[pl1974]

I needed more range for my commute (round trip of 35miles), so have taken the plunge and bought a new wisper.

As you may remember, I had bought a second hand one and had a lot of problems with the electrics, I eventually got it sorted, but it was only a 8ah battery, at over 3500 for 14ah, I decided to sell it and buy a new one.

Anyway, only had a very quick ride on it as need to give it the full 12hrs charge, but I have a few questions:

- Does it always function in pedelec mode? Is there a way of switching to pure power i.e. twist and go only? I thought I kept twisting the throttle by accident and then realised it was whenever I pedalled..

- It didn't come with a cycle computer, is that the case with the 2009 model?

- No pump, although I saw the other thread, although not sure what final position is.

- The gears didn't always select properly, I wonder if this is an adjustment issue

I only went about 50 yards down the road and back as was worried about the first charge, so didn't get much chance to have a play with it, I will go back to Stuart at Electric Bike World where I bought it from who seems like a really nice guy, but just wondered if anyone else had experienced similar.

My general impression of the bike is very good, seems to have nice quality components, looks great and the suspension was nice and soft. The big thing for me is the range though, for the trip to work.

Thanks,

Paul

I don't have a 2009 model, but little has changed as far as I know apart from a different battery setup.

It does always function in pedelec mode, but if you select 20% ('Low') on the handlebar box, you'll barely notice it. Unless things have changed it starts in 'Low' by default anyway. If you select 'High' you may well find that's a bit too exuberant for most purposes, unless you're riding on the flat with no obstructions or pedestrians. The throttle over-rides all of this, i.e. you can have power without pedalling if you twist the throttle.

You should be able to unplug the pedelec sensor if you're *really* keen on being twist and go only, but I don't advise that for reasons of warranty, unless you have a chat with the guys at Wisper first.

Don't know about the computer - first I've heard of one not being supplied even with the 2009 model.

No pump at the moment, but the guys at Wisper will send you one on request as soon as they come in. The original (2008 model) was dropped as being of poor quality.

If the gears are not selecting properly this will almost certainly be a tweak required on the cable. There's an adjuster where the cable joins the rear mech. If you're not confident any LBS will adjust it for you as the derailleur is just the same as would be fitted to a non-e bike. Take a look, though, at the protective bar over the derailleur mechanism - I have heard of at least one being bent in transit and fouling the mechanism.

There have been quite a few small changes, I'm suprised you have the power selector as it wasn't on my 2008 model.
An alternative way of disabling pedelec is to slide the sensor disk along the crank spindle away from the sensor, the 2009 model brings the chainring much closer to the frame so this might not be possible now.
I have also had a little trouble getting the gears to work correctly (i.e. perfectly) on the 2009 model, I haven't spent much time setting it up right though. The gears on my 2008 bike worked almost perfectly straight out of the box but the new one seems to insist on skipping a gear somewhere in the range.
My commute is only slightly further and may use less power as most is quite flat. I just take the charger with me to work instead of worrying about the range, that way if I get a problem and it hasn't charged* I have enough left to get me to the other end.

* It's very rare but has happened with both bikes and a 40 mile unpowered cycle to get to work and back before the next charge will not be fun.

It was introduced at the end of 2008, so mine (purchased on 2nd January 2009) has one.

Thanks for the responses.

Setting to low seems fine for the pedelc mode, hardly notice it, but just gives you a little help, the high setting seems a bit abrupt.

Got the gears sorted, just a couple of turns on the cable adjuster and it selects perfectly now.

I had found the saddle uncomfortable, but actually now I've got the tilt right I quite like the 'arm chair' design

No news on the pump and cycle computer yet though.

Have to say overall I'm really pleased with it, really nice and smooth, quiet motor which gives little resistance when not under power and I think it looks great. Looking forward to getting some miles in to see how the range goes - about 5 miles so far and still all green.

Now just hoping for the great service that is raved about from the guys at wisper - hint hint David

Haha! Don't forget that the very best after sales service is the type which is there but which you never need!

Quite....

A note about setting up shimano indexed gears: put the bike onto the seccond smallest sprocket - in this case 6th gear, then adjust the cable tension so it runs absolutely smoothly; this will set the cable tension corectly for all gears.

Managed to get out for a good ride today, I'm now up to around 27 miles, but I have a question about the handlebar power indicator.

The green light has stayed on all the time, but the amber one has been going off for a while now, especially on hills. I assume the battery is getting quite low (meter on battery only shows 1 light ot of four) Does that sound right though, I'm surprised the green stays on?

Thanks,

Paul

 

[Straylight]

Sounds like the amber and green have been wired back to front in the handlebar unit - if you contact Wisper service, I'm sure they'll just send you a replacement.

All the battery indicators do is measure voltage, which naturally dips when the motor is under heavy load - such as on hills. As has been mentioned elsewhere, the only true indication the lights give of the state of the battery is when the bike is at a standstill, and so there is no load on the motor.

 

[pl1974]

Thanks for that, not sure if they are the wrong way round as I'm still going at 35 miles now and I still have a green and a red? I've put it on charge now as not too sure how long to keep going for, I assume there is a low voltage cut out if I went for too long? Thinking about it maybe it is the wrong way round and its just really good range..

Noticed another problem tonight, there was a bit of clicking from where the pedal crank goes through the frame (not sure of proper name for it ) there seems to be a bit of play in it as it will wobble a bit, not sure if it just needs tightening up?

Thanks,

Paul

Try and work out if it's the spindle that's loose or just the crank, the spindle (bottom bracket) can be tightened quite easily but may have faulty bearings. If it's the crank it may tighten and stay there but if it keeps coming loose you'll need a new crank.
Both jobs are fairly simple and the retailler will be able to fix them quickly.

 

[pl1974]

Mussels, thanks. I assume the crank is the arm that the pedal connects to? (Sorry for my ignorance) If so then it definitely isn't that I think its the spindle.

I've been searching and it sounds identical to this

Problem I have is that I bought it from Southampton (I'm near Peterborough). Having had a poor experience from my local supplier previously (no names mentioned )

Anyway, I think I'll email Norman and see what he says.

Thanks,

Paul

New Wisper

Hi Paul

I am delighted you are pleased with the new bike.

Rog and Mussells have given perfect answers for all your original questions, however the click and strange lights would be best put to Norman on service@wisperbikes.com as he will be able to advise and send any parts if necessary.

Re the computer and pump, they are not supplied with the bikes any more as people seemed to prefer to buy their own computer and the pumps we originally supplied were dreadful. After a succession of very poor mini pump trials over the last few months we have at last found one that actually works, although the bike isn't priced with a pump we would be pleased to send you one when they are in stock with our compliments.

All the best David

 

[pl1974]

David,

Many thanks, Norman has come back to me and will talk me through the pedal adjustment and supply a new throttle. Very quick response..

Thanks for the pump, any idea on the timescales? I'll hold off buying one if its imminent, but will pick one up if not.

Pump

Hi Paul

We are getting three pumps in to test hopefully next week, maybe you could let us know what you think, we are loathed to buy 1000 of the things, as we did last time, and discover they are useless!

Pleased to hear Norman is looking after you.

All the best David

If you have one when you come up to mine I'd give a quick appraisal, I've tried a few different ones to compare with.

David,

That sounds great, thanks..

My pleasure Paul, and Mussells I will bring one with me.
