Garage Bikes is about 15 minutes from Elland Road so very doable in a lunch hour.
BUT it depends what you’re looking for – it’s more of a workshop that also sells a select few bikes rather than a showroom full of shiny new bikes, so maybe not the best for “tyre kicking”. Lots of nice shiny things to put on your existing bike though.
Also, they’re not open on Wednesdays, so watch out for that.
If you want something mending, or to buy parts, accessories, and tools, or if you happen to be looking for one of the bikes they actually sell, I can’t recommend them highly enough.
Also a wealth of local knowledge if you want to do any riding in the area.
