Storck Team Up With Cosworth On New Electric Bike Project - BikeRadar

Shame about the somewhat dubious stats and figures in that article. 250w? 100Km range? 2Kg battery?

I do like the design of the battery though. There's work to be done here on nicely packaged bottle mount batteries that fit in the main triangle.

The basic bikes are very tasty if expensive. I do like the idea of a really minimal weight and stealthy upgrade to a good hybrid bicycle.

I fear more marketing over substance

Dubious stats ? J, have you ever riden this bike? I don't think reputable companies like Storck or Cosworth would make false claims.....

NRG... There is a very heavy dose of Substance before marketing.

One thing I can tell you is that there will be 1 place for a Pedelec Forum member to come to the Press launch of the new Storck Cosworth bike at the Cosworth F1 engine HQ when we launch the bike. You will get to ride the bike, plus a VIP tour of the Engine building facility and chat with the engineers. We plan to run a competition here soon.

I don't know about the statistics, but if they go half as well as they look I'd love to try one.

The Multitask for me please.

 

[overthehill]

Great to see a development like this taking place in the UK all be it with German bikes. But pound for pound the Alien Aurora would get my vote at present.
With the continued entry of some big players entering the ebike market the future for sophisticated development augers well and should stimulate growth and competition which we will all benefit from.

And I'm sure an online website magazine wouldn't just quote figures straight out of a press release thrown together by a marketing manager.

I think that motor has been mentioned on ES (down at the moment). It's way more than 250w but might well be restricted for the UK market as mentioned in the article. If all you need is 250w, then 4.9Kg is very heavy when the small 250w Bafangs are more like 3Kg. The Bafang BPM, Ezee, BMC motors are all less than 4.9Kg and considerably more than 250w.

2Kg of LiPoly battery gets you 36v5AHr 10s1p with a case. That's possibly what's been done but it's only 5AHr. Which brings us to:-

A typical 250w, 36v10AHr E-Bike gets 30km or so range. A Panasonic system pushes this up to 50Km or so. Half the battery, so half the range is a long way from 100km.

So please excuse me if I take the PR figures with a pinch of salt. And do please set me right with some real world figures. Because at the moment, the figures in that article don't add up.

And like I said, I would welcome a high spec hybrid with a nicely packaged, minimalist, ultra light weight, electric assist package on the market. And/or a beast of a powerful, "off-road" only version.

Back in the real world of Ford prices rather than Bugatti prices, I'd love to see a LiPoly battery package that was as plug'n'play and safe as the typical Li-On or LiFePo battery pack. Except I hate to think what the battery-only price is going to be from Storck.

You can get 100km or more out of a 5ah battery: If your motor only gives assist up to 14mph, then you pedal at 15mph, which is not too difficult for a reasonably fit person on a flat test track or road, then you can go a very long way before your battery is flat.
Like all the other claims, the clue is in the words "up to", which means anything from 0 to 100km.

 

[overlander]

With all the new bikes coming out from large manufacturers maybe just maybe electric bikes are coming of age. One good thing is the big companies bring serious money and R&D budgets. So even if they only enter the market for a few years their developments will push electric bikes on.

But then that's not 100km out of the battery as it's not providing assist! The article claims 100km for the battery which is clearly dubious.... presumably and given a fit enough rider, the range could be 100 miles or more if it's ridden above assist, that's not the same as 100km out of the battery.

To get 100km out of a 10ah battery would see the Wh consumption at 5.76 / mile a very low figure, lower than the very efficient Panasonic system..... A 5ah battery would need consumption to drop to an incredibly low 2.88Wh / mile, you may as well forget assistance and use the bike without the added weight of motor etc.

 

[eddieo]

what an infantile and stupid "toys for the boys" kind of name for a dereastricted and presumably illegal bike "Cosworth" is........... Makes life rather easy for PC plod dont you think? Hello hello hello a cotsworth is it! right your knicked!

Bet you're glad you posted now tappy !!! I like the look of it - and gladly will reserve judgment on performance until reviewed. I seem to remember Cytronex and Gruber being shot down on performance claims ---- your prices seem on par with other top end Ebike producers including topend Kalkoffs. Best of luck !!!!

Thanks, yes. I'm happy to post here and love the debate and views. I have been in the Cycle trade long enough and know what to expect on open forums. I'm sure too that now we have a technical partner in Cosworth, one of the electronic engineers will pop on here at some stage and offer their expertise.

I plan to run a number of reviews and test in the media to give accurate information of their performance. But the bottom line is getting customers on bikes and trying them out. The bikes will do the talking

yes your milage would only limited by your fitness !.these sort of figures only work if they are power only without peddling

 

[TeTs.BiZ]

I've tried it.... and BIG thumbs up to this bike. It rides as well as (and has similar pedelec characteristics to) the Raleigh Dover but is even smoother and more powerful. It is definitely better than the Giant ebikes which I've recently tried and decided against. Rear wheel drive is (in my opinion) the best possible configuration for a powerful ebike. I like the bike a heck of a lot, so good luck Ian. This is one of those bikes that you cannot judge on spec alone, it has to be ridden to be appreciated.. so I would encourage you to get yourself a go.

[Deleted member 4366]

Thats exactly the point i was trying to make: "Range of the battery" is totally meaningless without qualification. Maybe this bike does have a good range with or without pedalling. I hope it does, but I'm sure that the only way that battery will do 100km on its own is if you drop it from a space shuttle. Pehaps you want to make a qualifying statement about the range, Tappy, but I guess not, because all the time we're discussing it, you're getting free promotion (of your product).

Absolutely, if they're as good as you claim they will sell like hot cakes, but until that claimed range is well proven people will remain very skeptical. I'm sure no offence was meant though.

 

[flecc]

No pedelec will ever have a valid range figure to quote, since the human part of the hybrid power is unquantifiable.

I doubt there is much difference between any two e-bikes of a comparable type, the overriding factors of total weight, journey speed and territory nature dwarfing the differences between bike models.

All new entrants to the market are welcome for the competition and choice they bring, and the Storck is as welcome as the other new high-end entrants from Bosch, Siemens, Telefunken et al.
.

 

[NRG]

I somewhat agree Flecc however, battery capacity does vary a bit between similar bike types and it's fairly safe to say battery consumption on average falls between 8 and 16Wh per mile. Now, yes, there are variations outside of those figures that throws a curve ball as our US friends would say but we know the larger battery capacities already available from the likes of Wisper don't make the claimed range in the article.

With a 370Wh typical battery where does that leave us? Answer is short of the claimed range by a fair bit and if we question the battery weight which points to a lower capacity we miss the claimed range by a whopping margin.

I agree about all new bike entrants to the market it's great and welcomed but they need to be believable, devoid of spin and bring something different to the market. Maybe they have achieved the last point only the future will tell.
