Renting
a Bike When You Get There
A bicycle is a great way to see the city and even get out
into the country-side. This is a great first-day activity
(for multi-day stays) because it gives you a chance to see
the overall view of the area you are staying in. Renting a
bike allows you to cover plenty of ground, yet still remain
immersed in the country's culture instead of racing by on
a bus, and you'll see plenty as you peddle around. You are
also able to go wherever you please, unlike a train or bus
system. Back allies and beach roads are yours for the riding.
Many cities, particularly in Europe, offer bike rental services. These services may be found at private agencies, hostels, hotels or even at train stations. Check your guidebook for availability.
Be careful when riding a bike in some cities. The road systems and traffic patterns will probably be unfamiliar to you. My bicycling rule of thumb is to ride as though you are invisible. Assume that cars won't see you and will probably cut you off and make turns in front of you. A helmet is a good idea if possible. As well, make sure that the bike comes with a lock to avoid theft hassles. If it doesn't have a locking device of some sort, don't bother. A stolen bike is sure to blow your travel budget.
