@gemmerbal I spent 12 years riding in and around Dubai....road, MTB and gravel.
It is brutal in Summer, but amazing during the Winter months. Do yourself a favor, DO NOT try riding on the roads alone. Stick to the cycle tracks and some of the outlying areas with a group.
The best introduction I can give you is to Stewart Howison on +971506804528 (Ex Saffa) and owner of Revolution cycles in Dubai. They have a great cycling team called CSD. Cater for all types of riders from weekend warriors to Elites.
