The Auster is the lightweight sports Helios. It's specified for fast sports or audax riding, it features a drop bar with STI shifters, and the 'Capreo' cassette for a wide but sporty gear range. It also makes an excellent lightweight tourer - definitely the 'grown-up' version.
The Circe Helios is an innovative and versatile tandem that is available in a number of different configurations according to your needs. Sporty or practical; for two adults, or and adult/child, the Helios is a bike the can be adapted to the difffering needs of a large cross section of riders.
Twenty inch wheels are the key to its versatility - allowing the frame to accomodate an adult pilot and a very small stoker - down to as young as five years old (with crank shorteners available for junior stokers).
Twenty inch wheels are also key to this bike's practicality - making for a short, less cumbersome package than most other tandems. This will be much appreciated when it comes to storage and transportation. Great for smaller York houses!
