There have been no closures in our immediate vicinity but the ads in the Yellow Pages are getting smaller.
The trouble with bike servicing is having the right parts and storage. If you need a part tyhat is not in stock there will be a 48hr delay while the part is sourced. This does not compare favourably with motor garage services which have daily parts deliveries from local factors. Deeper stock of spares would get around this but cost and space often step in the way. Then you have to store the darn bikes whilst the customer who was in a desperate hurry suddenly has a week on holiday and cannot be contacted.
Puncture repairs are a bind as they turn up out of the blue and require that a mechanic stop the job they are on to replace a tube. Then they have to start again on the original job and time is lost so this work is priced high.
Rest assured, workshop repairs are only profitable when a nail comes in and has cash thrown at the parts. A full service is £100 labour and may take two days work once you have cleaned it up, worked out what is bust and ordered the bits, fitted them etc. Consider the mechanic's pay and that seems cheap.
As for mailorder killing the business, tough. Websites are cheap enough to build these days and can be a good sales channel for any IBD. We may not like Wiggle and CRCs pricing but they are a fact of the market and so that is that.
