For all your local cycling needs, try the local shop, BG cycles at 48 High Street, Portobello (http://www.bgcycles.co.uk). Proprietor Bernard is supportive of the club and will do his best to source components at fair prices, or deal with your mechanical problems.
Just slightly further away is ACE Bikes, at 101 North High Street, Musselburgh. A new shop, with a good range, and a good attitude – give them a try. They offer Porto-Velo members a 10% discount on all bikes, parts etc. bought in-store, or a 20% voucher to spend in the shop when you order from them online: http://www.shopraleigh.co.uk/
Dr Bike (mechanic from the Bike Station) will be on the Prom, offering bike checks and repairs (free – but donations appreciated), about once a month. For dates, check out: http://www.thebikestation.org.uk/dr-bike/
If you want to take your favourite bike on holiday, you can hire a pro-quality box from an Edinburgh-based firm – go to www.bikeboxhireedinburgh.co.uk and enter freevelo as the code to get free delivery and collection.
Pedal on Parliament promotes safer cycling for all. Its third mass ride from the Meadows to the Scottish Parliament took place on Saturday 26 April 2014. Some of us were there, among thousands of others. For info, go to: http://pedalonparliament.org/.
Also well worth supporting is Spokes, the long established Lothian cycling campaign, which works hard to promote cycling as a means of transport: http://www.spokes.org.uk.
