I don't understand what this has to do with my complaint about the ill effects of the junk bike market. I was complaining that there isn't the chance for R and D, not about what it does to costs. And technology being passed down is again nothing to do with the issue. The issue I raised is the way the market has been distorted by products not fully fit for purpose marketed at very low prices, and the ill effects arising from that.
I've got nothing against the genuine budget end of the market as I've repeatedly made clear. A bike like the Currie Izip can be marketed in the region between £300 and £400, since it's design and tooling costs were written off years ago, it uses a simple low cost steel frame and lead acid batteries.
But when some one presents an alloy bike with full front and rear suspension, hub motor and lithium-ion battery at the same price point, saying it's a quality product, I take issue, for that just is not possible.
In the many posts against my point of view, just about every irrelevance has been raised, but no real answers to the central point I'm making. The genuine budget market has customers, the junk market all too often has victims.
Again, I've said nothing about banning the junk products, though judging from the reactions one would think I had. I'm just trying to convince that this junk product band isn't viable and harms us more than it does us good. But if any of you want to volunteer as potential victims, feel free, it's your money. I'll just continue to try to depress sales of those products and expand appreciation of what good bikes are. Note, not very expensive bikes as some have assumed I'm saying, but good bikes.

Sorry mate I didn't explain myself clearly perhaps - it was only my first paragraph that was strictly in reply to your post. The rest was a general response to other comments on this and other threads.
I totally agree with what you say about the 'junk' end of the market being no good to man nor beast, but realistically anyone who spends ANY money on goods bought 'sight unseen' over the internet without doing full and thorough research first is just asking for trouble IMO.

In the specific case of the Sustain Halley,and I imagine the Synergie Avanti(?) as I believe they're the same bike that we've been discussing here, it's performance has proved more than adequate for my needs so far.
I promised yesterday to post fuller details of my daily commute when I had chance - I have some details that I'll post now:
Monday - battery charged for New Forest Rally.
Distance to work 4.9 miles - first ~3 miles either downhill or flat - last ~2miles a long drag of a climb with 2 short steeper climbs. Managed to ride to the top for the first time.
Return trip via a GP's, Maplins and Tesco ~9 miles - first 5 miles downhill or flat last 4 miles generally climbing with several steeper climbs. I'll provide exact %ages for all the climbs in the next day or so.
Monday evening - not able to charge battery as I didn't have the charger. Buying the bike at the show Sustain had to send it on to me. (It arrived first thing Tuesday morning - Thanks.)
Tuesday - commute to work as described above - 4.9 miles. Down from 5 LED's to 4 LED's on my arrival at work.
Ride home - directly home tonight (didn't have to go shopping for ourselves or my in-laws like last night - 3 x 4 litre bottles of milk and two loaves of bread

) 3 LED's most of the way but the final climb which IS 10% defeated both me and the bike and meant a short walk/push to the top.
Last night the charger had arrived so I was able to charge the battery - took virtually a full charge of 5.5 hours and I did carry out one 'Mod'. I took the chunky off-road tyres off and replaced them with some semi-slick road tyres I had.
Performance riding to work this morning was quieter with less tyre noise and seemed 'sharper'. Whether that was a fully charged battery, road tyres inflated to the max or a combination of both I don't know.
It must be borne in mind that at 106 Kg (17 stone in old money) I am virtually at the maximum specified rider weight, the topography of the area means the next hill is never far away and as I am still recovering from a Stroke back in February my fitness isn't the best then any bike will be tested to the fullest extent.
Hope this info helps feed the pool of info and not fan the flames further
Regards
