For someone living in or close to the city centre these are great. For £20 a year, the bikes offer a fairly dependable mode of transport around the city, and a greener, cheaper alternative to the taxi or bus . If you have the app on your phone, you simply enter the code in the bike and it unlocks. There will be an additional charge of you go over 30 mins, but Belfast is that compact I've never had them out for more than 15 mins at a time. The bikes are generally in good working order, though I've used a few that have had small problems. There is a feedback function on the app if you need to report anything. Additionally, the support team (available on the free phone number) are very helpful and pleasant. The bikes themselves are quite simple with 3 gears , stand, lock, bell, lights, parcel basket and easily adjustable seat height. Very handy and enjoyable way to get around the city. For anyone just visiting for a few days, i believe there is an option for shorter hire durations. Also, for anyone apprehensive about the traffic, belfast has become very cycle friendly in the last few years, with cycle lanes throughout many parts of the wider city and 20mph speed limits in the city centre. read more
