Looking for recommendations for a good bike shop, in resort if at all possible?

We hired fs 29ers I’ll dig out the name.

Just came back from there. I didn’t hire in the end as my daughter was playing up so didn’t get a pass but spoke to the guys in Planet Bikes who were sound

planet bikes and evolution bikes .. only a few doors away from each other in costa teguise on the beach walk, our room at be-live hotel looked down on the shops , seemed good valve
also seen another 4+ shops in teguise itself doing hire bikes so plenty to choose from

Correction it was Evolution that I spoke to. Some half decent Treks to choose from

I stayed at be live lanzerote and there was a bike hire shop across the road.
