Wisper 806

[Bogmonster666]

Hi, after an extensive thread of musings, I am leaning towards a Wisper 806. Want to get people’s experience…so more focussed thread.

I’ll be keeping my crappy old mountain bike with a TSDZ2 for longer rides and when I want some exercise. I like the TSDZ2 ride but not the reliability.

The 806 is for shorter trips. I frequently need to do a ~12 mile round trip with a big hill that’s 16% in places. I’m happy with the hopefully more reliable hub motor and my understanding is that the 806 should get me up such a hill without killing me. Will be getting a cadence sensor version to keep the cost down with the medium capacity battery.

I need to use panniers so hope front ortileb panniers will fit on the rear rack - the hooks will fit with the battery and can mount far enough back to avoid heal strike? Had no issues with heal strike on a tern folder.

What’s people’s experience of out of warranty repairs?

Hopefully this will prove to be a good quality and reliable bike…

Now just need to find cheapest place to buy. Some places do Blue Light Card discount but not @Wisper Bikes. Would be happy with ex-demo but none in stock at the moment. I think the bike is reasonable value when looking at most of the other options but money is tight.

Did you have any reliability problems with your TSDZ2?

Does your bike have problems with climbing hills?

It’s currently in pieces in my conservatory…waiting for a new bare motor as looks like a hall sensor failure, so yes. Have also had to replace a bearing on speed reduction shaft due to water ingress.

It gets me up the hill fine, usually in tour on stock firmware. It does have dual chainrings, struggled a bit before dual chainrings in tour if the battery wasn’t fresh. I went up last time in sport and it died at the top - maybe just coincidence…but probably not. My guess is residual moisture and the extra heat generated by being a bit lazy on late night back from pub….small possibility it’s the controller as struggled to test the hall sensor with independent supply, not enough hands to hold everything reliably and turn the motor shaft but 99% sure it’s a hall sensor. Expecting new bare motor in a day or 2.

I like the TSDZ2 but don’t feel I can rely on it.

That's the cheapest I can find £1444 including the middle 575 Wh battery

If I were you I would just buy more powerful motor. From Woosh if you want to be on legal side or cheaper from PSW.

Did you climb slowly? You might have overheated it.

I don’t need a more powerful motor, I need a more reliable motor and it needs to fit a folder with disc brakes. I was climbing at 6mph at the slowest and that’s about 85rpm and towards the top of the TSDZ2 cadence assist range. 26 inch wheels, 34t chainring, 32t rear cog.

I will not contemplate a non 250w motor. Needs to comply with UK law as much as a kit bike ever can…

The motor windings look fine, no hint of discolouration as I’ve seen on folks who have overheated their TSDZ2. Intermittent fault, motor pulls fine until it doesn’t. Theoretically could be dodgy controller but one of the hall sensors was only reading 2.5v so unless it’s the controller pulling the voltage down on one sensor (and I did try and test with external power source).

I meant more powerful motor. Not necessarily illegal. You can buy 3x more powerful motor from Woosh witch is still legal.

54Vx15A=810W of input power. That is a lot.

Eventually buy a powerful 48V hub motor.

I’m not sure how a more powerful motor solves my current problem of water ingress, crapped out hall switch, inability of current bike to bend in the middle, and annoying v-brakes.

My current motor is powerful enough when it is working. I feel that I’m chancing my luck every time it starts raining. I don’t believe it overheated, I have a suspicion that previous water ingress with heating and cooling have not helped its longevity but hard to know. Could just have been a defective hall switch.

Albeit at a price, the 806 sounds better suited to inclement weather, possibly more reliable design and build quality, bends in the middle and does have disc brakes.

I’m also paranoid about what I think @guerney calls impromptu, permanent folding of the type where the hinge fails or the frame sheers off. It feels like @wisper have had a good record with regards to avoiding catastrophic folding failures.

We have owned one of these for a year.
It’s been so reliable, no warranty issues, lots of unmade roads near us but, it travels over them with ease. I can load this into the boot of our car for holidays, it’s 21 kg . I’ve looked at others but, after a year of heavy use. I’d buy this again.

I bought an ex-demo 806 direct from Wisper (Amp cycles). I'm a bike novice, and the only disappointing thing for me was how badly corroded the spoke nipples and rims were. ~6 months in, I was breaking rear spokes to the point where replacing the rims and spokes was the only option.

The bike is on the train 3 days a week, and it's a heavy beastie to lift on and off, but manageable.

Power wise, it suits my journey just fine. Mind you, 3 miles along the canal and a mile of not particularly hilly road, to Milton Keynes for a bit of an uphill mile to the office is the daily trek. I have to charge the 575 battery every week, as it will just do the 3 days on maximum assist. I push it to a steady 15.6Mph on the gauge all the way though.

I do really like the bike, but I have no experience of others. I'm invested in this and have upgraded to 180/160mm disks with hydraulic levers/calipers. Replaced the default 7 speed shifter, with another Shimano version (just because it suited me better under the handle bars).

Would I still buy it today? It's relatively expensive, but has all round disks - I didn't want V brakes. I would probably test ride a few similar bikes before saying, yes, for sure.

 

[Wisper Bikes]

We used to have corrosion issue on some of our spokes a few years ago, but we have sorted the issue now.

Please PM me with your email and I’ll see whether your bike was one of these.

Thanks for your kind words.

All the best, David
