I have collated the results and presented this visually. If you want to add your brands - do it in that thread, this thread can be for discussing the tally.

Tips
• The pie chart is anti-clockwise, Giant first (dark blue) then Avanti (orange).
• In the legend read the first row across Giant, Avanti, Trek, Specialized then the next row, Malvern Star, Repco etc.
The pie chart and brands represent 75% (875) of the all bikes.
Here the top brand percentages overall (of the 1167 bikes)
10.9% Giant
4.88% Avanti
4.37% Trek
3.86% Specialized
3.66% Malvern Star
3.60% Repco
3.17% Apollo
Interesting what does and doesn't match the 'ultimate guide' survey I conducted (that is currently in work).
We should be fair in noting that the tally in the forum has been prone to human error - and may also be skewed - but none-the-less, interesting to see.
