Cycling activities in Luxembourg
The topography's not flat, but those with decent muscles will find Luxembourg City great for biking. The only rental outlet, and it's a good one, is Vélo en Ville. Children's bikes are available (same price as adult bikes), as are toddler seats. Under 26 year olds get a 20% discount (not available on half-day rentals).
An excellent route to start with is the 40km Piste Cyclable du Centre (signposted PC1),which circles the city's outskirts. The Vélo en Ville crew supply a basic B&W map of this route.
