I’m local
I live among, and ride with the people whose bicycles I service—It's in my best interests to make people happy, and for them to trust me.

Parts & accessories

Practicality and quality—both important
It’s why I carry an inventory of retail parts and accessories for things that you need here and now. I also think it should be fun, so I source out interesting little bits & details to have on hand for when you want to personalize your bike.
- Tires, tubes, pumps, Co2, sealant
- Chains, missing links, lube
- Brakes, cables and housings
- Bottle cages, bottles
- Handlebar tape
- Saddle trunk bags, panniers, racks
- Tools
- Lights
- Cycling gloves
If I don't have it in stock, I can order it.

Testimonials
Deanna T. (Cobourg)
Randy has repaired 2 bikes for me over the past year. Once done, the bikes felt like new again. Gear changing is now smooth and comfortable. Randy has a passion for bikes and cycling and does a great job!
Mike C. (Cobourg)
In addition to his technical know-how, Randy has a couple of rare qualities that make him an excellent bike mechanic; he’s assiduous and diligent. He’ll take care of the bits of your bike you never even knew you had.
Debbie P. (Warkworth)
I have used Randy’s Bike Repair Service for several years and have always found it to be excellent. Just one example, last year I had a malfunction resulting in my front derailleur being ripped off the frame. It was unrepairable – nope. Randy got me back on the road to finish my ride and then took my bike into his shop for the full repair. He reconfigured the front derailleur attachment and was able to repair the damage and have it running smoothly again quickly and efficiently. I highly recommend Randy's bike shop - he can fix anything!
Lydia B. (Port Hope)
I met Randy in June 2022, when he and I worked together to source bicycles. make them road-worthy and available to those who couldn't afford them. Out of this I can heartily say that Randy is extremely knowledgeable about all components that make a bike safe, and he can take a look at your helmet too! Last, but not least, he is thorough, sympathetic and patient. You are in good hands with Randy.
Rich R. (Cobourg)
Just wanted to thank Randy for the great job he did repairing my wife Carol’s bike. I normally do the small adjustments on our bikes, BUT when things get over my head…. I head to the best! and Randy is exactly as he describes himself. He had my Carols bike up and running in no time.
Honestly, if want integrity, professionalism, friendly environment and most importantly your bike fixed correctly!! then Randy is your guy! Thanks again Randy…. See you on the roads
Freda D. (Cobourg)
Randy is both meticulous and thorough which are desirable qualities in a bike mechanic. I'm very happy with the repairs and servicing done on my bike and I always trust Randy to do a great job.
Angie M. (Cobourg)
Randy is the ultimate in friendly professional. I have brought two bikes to Randy's Bike Fix for assistance in fixing and tuning up, with issues ranging from disc brake repair, brake cable reinsertion, and unstable gear shifting. Each time Randy takes care to not only address and fix the problem, but to ensure the entire functioning and appearance of the bike is tip-top! He even explains the process of repair and provides advice for upkeep, and we've gained so much knowledge of bike mechanics as a result. Going above and beyond, Randy's is clearly living his passion and purpose by servicing our community's cycling needs. Thanks Randy!
