Bike hire in Royal Deeside Scotland

Hello

I’m looking for help to find a place where I can hire a road or mountain bike in Royal Deeside, Scotland.

I’m travelling to Scotland to compete in Scottish six days -competition (orienteering). I’ve injured my knee and it looks like I won’t be able to compete due to this injury. I have paid for flights from Finland and for accommodation, so I will go on this trip despite the injury. Instead of orienteering I thought that I could hire a bike because the injury doesn’t prevent me from cycling.

I’m going with few friends who are competing, so my thought is that I could hire a bike near the place where the stage of the competition is taking place. We have a rental car so getting around is easy.

First stage is in Glen Tanar (https://www.scottish6days.com/2017/day-1-glen-tanar)
Second in Balfour Forest (https://www.scottish6days.com/2017/day-2-balfour-forest)
Third in Birsemor Hill (https://www.scottish6days.com/2017/day-3-birsemore-hill)
Fourth in Creag Choinnich (https://www.scottish6days.com/2017/day-4-creag-choinnich)
Fifth in Glen Feardar (https://www.scottish6days.com/2017/day-5-glen-feardar)
We are staying in Glenshee so I could also hire a bike from there.

I really appreciate your help on finding a place where I can hire a road or mountain bike.

Niklas
