Answering common questions......

Hopefully the questions below cover most of the common queries people have about the Eos. However, if you can't find an answer, then please ask us directly. If it's a good question, we'll add it to the list!
HOW IS THE EOS DIFFERENT FROM THE HELIOS?

The Eos takes its design cues from the Helios, but, by using a larger wheel size, carbon fork and belt drive options, and generally higher end componentry, has increased appeal for sports and heavy duty touring crews. The frame is also slighly longer than the Helios to facilitate a more stretched position, particularly for taller riders.

WILL WE FIT THE EOS?

Almost certainly! Like the Helios, we designed the Eos to be ‘one size fits nearly all’, however, the Eos has slightly longer top tube and seat tube dimensions. With its telescopic stoker stem and versatile bar options, it’s still suitable for a very wide range of rider sizes, though not for very small children.

If you’re not sure, get in touch with us.

WHAT ARE THE WHEEL SIZE OPTIONS?

The Eos is designed to take both 26″ (ISO 559) and 24″ (ISO 507) wheel sizes. For sports type riding, we recommend the 26″ wheel/tyre with 28mm Conti Gatorskins, and for touring/mixed surface type riding, the 24″ wheel/tyre with the 47mm Schwalbe Marathon. Depending on your usage, there are other options in both sizes.

WHY DID YOU DESIGN YOUR OWN FORK?

We wanted to use carbon for our fork because with careful design it can be light and stiff, yet strong enough for tandem usage.  We also wanted a thru axle design suitable for 26″ road and 24″ touring tyres, that had mountings for mudguards and rack. Not surprisingly, there was nothing available, so we designed our own and worked with a carbon fork specialist to get it manufactured.

YOU ONLY OFFER TWO MODELS, WHAT IF I WANT SOMETHING A BIT DIFFERENT?

We build all our tandems to order in Longstanton, such that, within the bounds of compatibility and availability, we can accommodate any modifications, or even a complete custom spec.
In fact, we enjoy working with customers to achieve a bike that is as ideal as possible for their requirements.

WHAT ARE THE RIDER WEIGHT RECOMMENDATIONS?

We recommend a combined maximum weight for both riders of 170kg. Within this limitation, we recommend that the front rider should not exceed 100kg and the rear 80kg.

CAN I CARRY LUGGAGE ON THE EOS?

The Eos can be fitted with a conventional rear rack for using typical bike panniers and/or rack top bag. The carbon fork is also designed for taking a low rider rack for front panniers.

If more capacity is needed there are a variety of bags that will fit on the Stoker bar or one could use our Atlas trailer.

HOW CAN I TRANSPORT THE EOS?

The Eos can have our Separable system installed, making it suitable for airline friendly one or two case packs.

WHAT ARE THE EOS DIMENSIONS?

With the 26″ wheels the Eos has an overall length of 2330 mm. The wheelbase is 1724mm.

 

DOES THE EOS COME IN ANY OTHER COLOUR THAN GREY?

Although we think the standard Eos matt grey looks very good, we understand that it’s not to everyone’s taste and offer custom paint finishes. Depending on the finish and complexity of the design this is from around £350.
