Look I do agree with all last few posts.. Yes for some ( as I,ve said before) is perfect. Yes it will climb given the criteria mentioned. And to be fair it was infact the Wisper Site itself that started the debate. Google"Wusper Torque" and first thing seen is " A real alternative to Bosch...

Also I notice your Riese and Muller e mtb has Bosch crank drive. Which one is best for climbing David. The Wisper Hub or the Riese Muller ( Bosch ) Crank. ??" In the blurb the Riese Muller mtb is aimed at serious moutain bikers going on challenging rides??

I see all that d8 but lets assume 2 scenarios. A) hub and crank are fitted with identical "nominal" 250w motors/ cintrollers/ pedal sensors.. Owing ti the greater range of ratios available to the motor in the CD it must benefit at some place in its range of use...In this case I,d hazard a guess...

David I never mentioned Wisper Torque, which by the way I have ridden, unfortunately not on steep enough hills or over a,long enough time to give an objective review. I offered to meet up with OP at a severe climb near us both to compare bikes .(Offer still stands. Winnats Pass) The thread...

I,m not asking for favours. I,m pointing out there is a vast amount of " information" and "evidence" contradicting the concepts generally held on here.. Both " screenshots" taken from highly regarded sources.( and different) I,ll post sources, thought it was on heading. ( ebike " an...

O I,m just glad I found the sole enlightened forum dedicated to legal pedelecs. ( bet my smilie doesn't show) Another unenlightened journo... just all over place...

Seems you may well have convinced me, but not everybody sees it that way ???

Think unsprung weight might affect handling a bit... This years Mugen made little if any improvements in battery/ motor...did a fair bit of lightening and Showa developed a single sided ( sort of) front suspension...one side took stresses, other side dampening...lowered weight and unsprung...

Thanks ...

Thinking of new phone so it might be better going same route (??) Any problems with battery usage..( on phone !) Ps Thanks for info.. I tried Nokia , app seemed absolutely fine...but couldn't see screen on move ( or stopped in bright sunlight !) Do you get a track to follow without down...

Think Honda Mugen developed it. ( or paid for it) Its the future...not long before an electric superbike...my money is on ktm tho... KTM freeride E is a right piece of kit. Had a go on one , just superb..

Since getting Ebike found I,m travelling loads further on trails/ tracks, took a wrong turn today, 4 mile detour...fortunately plenty in battery.. Thinking of satnav...with basemaps?? Anybody know anything or got one?? Tried with app for Nokia 625...not really successful !

Impressive, bike and rider.. Wonder what motor/ battery. Racing actually suits regen. If bike/car isn't accelerating, braking or cornering it ain't winning. Bikes in Zero are now most valuable !!

That's pure crazy... Its reckoned both with bikes and cars you have to get over 350bhp/ ton to crack 12 seconds.... Bike looks heavy.. All up 150 k ??? Must be hellish powerful...but looks like its doing it.I,d give him a run...fireblade 7... Tell you when I was impressed, first 100mph lap in...

But only on here could we argue about an argument ??? A good bike... Somewhere I there was a claim about an ebike ( based on push bike presumably) that could do standing quarter in 11 something seconds...now that takes some believing... My Westfield with 2.0 Zetec could just about manage 13...

Only conclusive if you discount a few opinions early on in thread... Later ones made more sense...but interpreting thread is like original argument...open to interpretation depending on what you want to believe...and probably thought in first place...its that momentum thing again...

Read all that...conclusion seemed to be there wasn't one ??? When I worked in industry it was taken as a truth that for higher efficiency...higher voltage..lower current...but more dangerous...but things move on..we didn't have time to debate as in link...needed to get it working yesterday...

What's your bike if not geared hub then Daniel ?? Assuming direct drive ??

Good post... Totally agreed ...every point..

On motor efficiency ...my response was missing point a bit.. Fewer windings/ higher current as almost got to be overall less efficient. Induced internal voltage will be very similar but heat generated / losses will always be worse with equal power ...heat waste is proportional to current...
