Circe Thule stand off

The Thule stand off allows the Helios tandem to be fitted to a Thule Proride 591 or 598 bike rack. By adding the stand off the Helios can be easily and securely attached to the rack. The stand off is not required if you have the Helios front stand fitted to your bike, though you will need a strap to secure the front wheel.  

SKS Mudguards

Not essential, but make for a much more pleasant riding experience when it does get wet. These full length guards are made specifically for our bikes, so fit like a glove! Weight: 540 g

Ursus Jumbo Stand

The double-leg, wide stance of this stand means that, even when loaded, your bike will remain upright and stable. It will fit both the Helios and Morpheus, but causes interference with derailleur gears, and can only be fitted to models with a hub gear.

Weight limit - 55kg

Demountable Pedals

The Wellgo  range of demountable pedals provides a great way to quickly remove, or swap around, pedals. Particularly useful on the Helios and Separable Helios, where they quickly make the bikes into a much narrower package for transportation, storage or packing in the suitcase. The range includes includes flatsided, clipless and flat/clipless hybrid style pedals. Supplied with cleats and fitting instructions. Prices range from £50 to £85

Pletscher stand

The Pletscher twin leg stand cleverly folds away to one side allowing it to be used on derailleur geared models. It doesn't have the same wide foot print or high weight limit as the Ursus Jumbo, but is a far neater option for those who just want a way of supporting their Circe while they have a Latte! Weight limit - 25kg Weight 540g

Thudbuster post

The Cane Creek Thudbuster is the Rolls Royce of suspension seat posts. Particularly popular for stokers on the Helios tandem, it can have benefits for the captain on either the Helios or the Morpheus. Either way, it eats the bumps, so you can enjoy the ride! Comes with 27.2 to 30.2 mm shim

Morpheus Stand

If you're looking for maximum stability then the dedicated Morpheus front stand offers exactly that. It is easy to deploy with the stoker in place and folds away neatly without affecting panniers mounted on the Mid rack. It secures simply and securely to the stoker handlebar and bosses on the down tube.

Weight limit - 100kg

Lighting

The various potential uses of Circe bikes often make a hub dynamo lighting system a very useful add-on. We recommend and fit systems using hubs from Son or Shimano combined with different lamp combinations, depending on usage, from Busch and Muller. Prices from around £190 for an upgrade to an existing bike.

Helios Front Stand

The Helios front stand fits to the captains bottom bracket, providing a secure way to support the bike when you have children or luggage on the back. Located at the front, it makes getting the bike on and off the stand easy when loaded. The stand can be retrofitted to any Helios frame. Weight limit - 50kg

Recurve seat

The Recurve seat is fitted as standard to the Morpheus. It's one of the most popular designs of recumbent seat, and is particularly suitable for sociable cycling, providing good location and supreme comfort!
