20" 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!

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

Circe Stoker Stem Extension System
The Stoker Stem Extension system (SSES) replaces the standard inner section of the Stoker stem, raising the bars by 135mm. The SSES is particularly useful in situations where the Captain is shorter then the stoker, or, when the stoker likes a more upright riding position. (note - the handlebar is not included)
Helios Front Stand STEPS E6100
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 Helios STEPS E6100 frames.
Weight limit - 50kg
Thudbuster post
The Cane Creek Thudbuster ST G4 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
Freewheel crank
Our freewheel crank is a great option for crews who want some independence in pedalling between the captain and stoker. The most common configuration is to have the freewheel crank fitted to the stoker position, allowing the stoker to stop pedalling independently of the captain. It is also possible to have them fitted in both positions, or just the captain's position. The freewheel crank comes with a 110 BCD double spider which can take rings from 34T. Note that the crank is supplied without rings, bottom bracket or chainguard. If required, we can supply these at additional cost.
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 £200 for an upgrade to an existing bike.
