Circe Cycles Helios Tandem Bike - Duo

The Helios is a compact and light tandem, ideally suited to city and sporting use. A bike that would handle and perform at the highest level, easily fit a wide range of different size people, yet be compact for easy storage and transportation. It works particularly well for commuting, the school run and sporty day rides. People carrying, child transportation, shopping, cycle touring, exercise, sport and just plain old fun, the Helios can do it all.
Your price: SGD$2,850.00

Product Features:

•         It can be fitted with a conventional rear rack for using with typical bike panniers or rack top bag. It also has a mounting point on the head tube that will allow the use of a variety of bags (particularly “Brompton” related bike bags) or baskets. Ideal for shopping or cycle touring and not being attached to the fork or handlebar, there is minimal affect on the steering and handling.
•         For heavier duty load carrying, the rear seat post can be removed and substituted with the dedicated Cargo rack system. This will take two child seats, or any variety of bulkier items across the wide platform rack. There is also the option of a low rider rack system for the front fork.   
•         It can carry up to two children in child seats or with the remarkably low saddle position and the Circe crank shorteners, even a very young child can pedal at the back.
•         With the separable kit, the Helios will fit into a flight case or two conventional luggage, making flying hassle-free on airlines with sports equipment/bicycle restrictions.
•         With narrower tyres and drop bars the Helios makes a remarkably fast tandem.
•         With its low step-over height and easy size adjustment, it is particularly suitable for visually impaired people to cycle together too.
•         Using 20" wheels that offer an unbeatable combination of strength and light weight. It also makes the tandem more compact and manageable. There is a vast range of tyres available from the super light, fast, general use or touring tyres.
•         With the front wheel removed and the handlebar and seat posts quick released off, it will stand upright across the diagonal of the luggage space (rear seats folded) of most small to medium hatch backs. There should be enough room for the front passenger and depending on the rear seat arrangement, might be room for a passenger in the back.
