Agattu Agattu.. wherefore art thou?

[musicbooks]

Where is the Agattu diamond frame.. 50 cycles?? I wish to be a full member of the e-bike community rather than a whingeing nearly ran...

Thanks Flecc.. Good to see a responsive and dedicated company working in the evening to sort out customer concerns.

I begin to feel almost guilty that my Agattu came so speedily, Tom. If your diamond job is as good, when it comes, I'm quite sure you will feel the wait has been worthwhile. And at least you are missing some are really cold biking weather!

Thanks Tony for your kind words.. I believe the wait will be worth it, and I don't want 50 cycles to rush anything unecessarily including PDI's. We've already had a pedal falling off as it had been misthreaded, a stand that snapped and a pump missing.. so I am happy to wait a few more days if it comes in perfect order and condition.

I'll keep you posted on how I get on when it does finally arrive.

A stand leg snapping is not necessarily a bad thing on this kind of bike with integral stand.

The stand is mounted on a plate welded to the lower rear A frame tube.

If the stand leg were much stronger, the thin lightweight alloy frame tube would be twisted and split, a disastrous occurrence.

This sort of sacrificial engineering design choice is common in many fields, not just bikes. The moral is not to strain the stand leg and/or drop the bike's weight onto it, just resting it on the leg without undue force. It's more than strong enough for the weight of the bike with a carrier load, but with little margin for abuse.

The stand manufacturer, Pletscher of Austria, are a well respected name in the manufacture of these items.

Thanks Flecc ..I didn't suspect a design fault for one second..

Is there anything you DON'T KNOW about e-bikes??

I always respond to this question on any matter by saying, for every one thing I do know, there are an almost infinite number of things I don't.

Reminding myself of that ensures that I never get big-headed about my limited knowledge, and remain aware of how much I depend on others for all the near infinite number of things where my knowledge is lacking.

While I am sure you are right in general terms, Flecc, that wasn't the case with my particular problem. I had hardly used the stand - certainly not roughly in any way being well aware of my weight putting stress on the bike generally. The arm snapped cleanly in half, not while the bike was standing on it, but as I flicked it down to stand the bike. The broken surfaces showed what seemed to be very large crystals over most of it with just a portion round the edges appearing different, I thought less crystaline. I'm no expert of course but I thought that all indicated a casting fault of some sort.

I have been bothered about the way the prop is fitted to the frame as It seems to me to putting hefty stresses on small areas. Do you think one ought to perhaps fit a two armed stand which would not have this problem?

Perhaps it would be better for all concerned, supplier and customer if Derby Cycles could announce an actual date when bikes will be shipped to the UK? Is that so difficult?
Surely they know how production is going, how many of which particular model they are building and when they will be ready.
I would imagine the Derby Cycles pedelec models are built to order rather than being available 'off the peg' as these bikes are not sold in huge numbers, that is understandable.
If that is the case wouldn't it be better if 50cycles said, available to order and stated that on their website rather than "in stock very soon"? This might end the constant speculation.
The fact that no actual photos of the diamond frame Agattu are available from any source other than my Photoshop mockup (see attached image), would suggest none have actually been manufactured yet.

That mock-up is very clever. Nice one

I remember seeing an A2B letter with someone who had the two arm pletscher stand fitted to a lafree with child seat and pram carrier. He swore by it and said it made a huge difference as he could reliably get off the bike and leave his baby in it. These two pronged stands are way more stable. Needless to say i have one on order.........
