A city bike is a great alternative for commuters who have quite a journey from their train stop to the office or the classroom. They’re lightweight, fold up to the size that’s comparable to the circumference of an open umbrella and, most importantly, they won’t set you back a lot of cash. If you´re looking for a bike to ride to school or work or if you need a bike to take with you on holidays, a city bike is a great choice. You can also use a folding bicycle if you want to go bike riding for exercise, but be aware that a city bike is not suitable for long trips or for riding in rough terrain. If you´re looking for a bike for trail riding or endurance racing, we advise you to look for a racing bike or mountain bike instead, which you can also find on Kelkoo. If you want a high quality folding bicycle, we recommend a Brompton brand bicycle as they are renowned for their superior products. If a Brompton is too expensive for your budget, there are plenty of bikes for under £100 available from Amazon and eBay.
