Thank you all to the 14 cyclists who participated in my "Designing by Consensus" social network questionaire.
This survey was to help design a Belt Drive Singlespeed 29er Mountain bike.
Although the survey pool was small, there are some interesting and unexpected findings.
I do not think we have anything close to Homer Simpsons car, so we have a chance to get a good design here.
I am no expert and the data could be considered biased, but this is my take on the results.
If I was to summarise the results, the design criteria would be as follows:
Almost everyone rides in winter or the rain on mostly local trails.
All of you have ridden recently with longest rides of over 50-100miles.
This bicycle has to be belt drive (10/14). 4 people did not answer this question.
Singlespeed (9/14). It was interesting to see 1 person wanting to try singlespeeding.
29er Wheel size (7/14). There is still 26 inch riders out there and 650b is coming.
I still think that 29 inch wheels have a lot of benefits and suit all but the shortest of riders.
Tyre clearance for 2.3 tyres (7/14).
Front suspension (6/14). This was lower than expected, but the results are saying that a design for both rigid and suspension is needed.
In the spirit of social-media and "open-source" a summary of the raw data follows:
What size diametre tyre do you ride?
26 inch 5
27.5 inch 2
29 inch 7
Do you have front suspension?
Front and Rear 2
Not for Winter 4
Not Ever 2
What width tyre do you prefer in summer?
2.1 XC Tyres 4
2.3 AM Tyres 7
