Re: Choosing a club

I joined a club 11 miles away for similar reasons. Although I initially drove down with my bike in the car, once I got to know people a bit, I rode my bike down, did most of the club run, then left at a suitable juncture. That occasionally meant doing ride distance + 22 miles, but if I didn't feel u...

Re: Choosing a club

I think you should go for rides with both, and maybe a few others and see which suit you best for your goals & types of cycling.

Re: Printers

You can use a normal vacuum cleaner. I recommend replacing the plastic hose with a rubber one, or getting the sort of hose attachments that copier / printer technicians use. Although I have to admit that I cleaned a printer without replacing the hose, but the printer was on last legs, anyway, so I j...

Re: Posterior Vitreous Detachment, (PVD)

First, I suggest that you call your specialist and ask.

I don't have any medical qualifications, but I wouldn't think that gentle cycling is a problem. That might mean getting off and walking for hills. Personally, I'd be super cautious given that the possible outcome is loss of sight.

Because a disgrace.

Maybe the glue on his haripiece is water soluble :lol: :lol: Or perhaps he's worried about the boatload of hairspray he uses to keep his do in place.

Re: Are Strava heatmaps reliably indicative of general cycling activity?

I don't think that there is a problem with using strava data as an input to local cycle strategy & provision. However, I don't think it should be the main input. Furthermore, it is extremely important to understand the limitations, and make sure to include data from the sort of cyclists represen...

Re: Are Strava heatmaps reliably indicative of general cycling activity?

Ideally you want to minimise the selection bias inherent in something like Strava. There's two alternatives I know of. One is plain and simple old-fashioned traffic counters, which exist for all A roads, many B roads, and a smattering of smaller roads. But possibly more interesting is sensor data f...

Re: How to pay it back

One of the most rewarding things I've done is help out at cycling days for special needs kids, with adapted equipment, such as trikes, recumbents, and hand crank bikes/trikes. The equipment belonged to TrailNet (Thorndon & Great Notley country parks). I've also taken blind stokers out on our chi...

Re: Are Strava heatmaps reliably indicative of general cycling activity?

Wanlock Dod's point about lack of normal distribution is very valid. I had the Glasgow data a couple of years ago and noted that while the correlation was positive, the survey points were very skewed towards to quieter routes. I had parked the correlation as interesting but inconclusive. I received...

Re: Are Strava heatmaps reliably indicative of general cycling activity?

1) I accept that the point about comparing disparate datasets. What I think I have shown is that at a gross level the datasets correlate well. In themselves they tell us nothing about who is cycling, men or women, but as far as I can tell, the Strava demographics and the demographics of the cycling...

Re: Are Strava heatmaps reliably indicative of general cycling activity?

I have some questions, and also would like to point out some possible issues.. Who performed the cycle surveys? DfT and some local authorities do not include cyclists who are not in the main carriageway. Were any segregated facilities included in the comparison? I certainly donæt believe that roadsi...

Re: How to pay it back

Bikeability don't actually make kids wear helmets. In fact National Standards used to say (I haven't been teaching for a few years) that benefits and disadvantages of helmets should be explained, but nothing more than that. Many Bikeability schemes are run by local authorities, however, and they req...

Re: How to pay it back

I was going to suggest either 'Bike it' or 'Go Ride' or both. If you look on BCs site, you can find a local Go Ride club, or if you are interested in a local club, you start Go Ride, there. You could also potentially help one or more schools start after school cycling clubs, maybe in conjunction wit...
