ICE's White ICE Cycle

The White ICE Cycle

We have used our knowledge and expertise in bringing together some of our parts from our current trikes along with a few custom built additions to produce a monster that has the capabilities to go the distance.Here at ICE Trikes we have been given one of our biggest challenges to date; to design and build a cycle capable of conquering the savage conditions and hazardous terrain of Antarctica. Our current ICE trike range was going to make a sound starting point for such a vehicle as it combines stability with an incredibly comfortable riding platform and a dependable frame. However, it was going to require some radical alterations to make it suitable for traversing the extremes of Antarctica’s climate and terrain.

The trike is a tool which will be used by the very capable Maria Leigerstam in her attempt to reach the South Pole. Maria has previously completed such extreme challenges as the Marathon des Sables (5 and half marathons in 6 days through the Sahara desert) and the Siberian Black Ice race (379 miles up Lake Baikal in Siberia). These are two of the toughest races on earth in the two extremes of weather conditions.

Some of the parts which are standard to both our production machines and the Antarctic expedition trike are listed below with the custom designed parts listed below that.

 

Standard Components

ICE Ergo-Flow Mesh Seat

The ICE Ergo-Flow mesh seat utilises the latest in advanced materials to deliver durable comfort and support. The seat frame has been precisely designed and constructed to provide optimum back support. The frame is fitted with an ergonomically designed cover made from breathable fabrics to maximise airflow. Cushioning in the base and side bolsters enhance comfort, and tension in the back can be adjusted. This will give Maria comfort and stability for the 18 hour days she will be putting in on the trike for the duration of her 20 or more day expedition.We have used our knowledge and expertise in bringing together some of our parts from our current trikes along with a few custom built additions to produce a monster that has the capabilities to go the distance.

Steering and Geometry

The trike is fitted with our standard indirect steering for natural and intuitive handling which will remain controlled, predictable and light, even under the difficult undulating surface of Antarctica. The steering system dissipates vibrations and shock before they reach the hands to give a comfortable and safe feel.

 

ICE 4130 Chromoly Steel Cruciform

Aircraft-grade heat-treated 4130 chromoly steel provides ideal qualities for the cruciform: strength, fatigue resistance and vibration absorption. The design exploits these properties to give unique handling characteristics and superior comfort.


Custom Components

ICE Big Back-End

The Back-End has been redesigned from the ground up, incorporating a step-down mid-drive and the ability to hold a 4.8” Surly tyre, giving both the power and grip that will be required is soft snow. It has been constructed from aircraft-grade heat-treated 4130 chromoly steel all hand braised together in our workshops in England. It has been specifically constructed to be able to handle the forces from the extremely low gearing especially at the low temperatures it will be subjected to.

Rack & Rack Extensions

We have taken our tried and tested rack top and sides, and provided an extension rack with support stays to provide extra capacity to hold all of the bags Maria will need on her journey. The rack has undergone rigorous testing and has been proven to hold 100kg+. The large load set out over the back wheel will also have an added benefit of providing the rear tyre with even more traction.

Surley Big Fat Larry Front Tyres

The Larry tyre measures about 4.7˝ wide, a wide tyre was essential to give the float required not to sink into the snow. It also had the benefit of having a suitable tread and grip needed for the soft ground.

Surley Lou Spiked Rear Tyre

ICE Started with a standard Surley Lou which is a 26 x 4.8” rear-specific tryre. The Surley Lou’s tread has tall knobs designed to grind, crawl and claw its way over icy, snowy, wet, loose or otherwise inhospitable terrain. After a lot of testing Maria then added some spikes to the rear wheel to give it far more traction in icy conditions.

Mid-Drive

Starting with a standard mountain bike chain-set we have engineered a mid-drive that will provide an extremely low gear. In addition to this, we have designed heavy duty guards to protect the chain-rings which serve a dual purpose in preventing the chain from dropping off. The mid drive steps the gearing down by 2:1.

ICE Custom Boom

ICE has specifically designed the custom front boom to excel in tough conditions. We chose again to use the heat-treated 4130 chromoly steel for its reliable qualities. A curve has been added to the boom to help improve the circulation to the feet in the cold weather.

YBN Chain

We have selected a heavy duty YBN mountain bike chain. The low gearing of the White Ice Cycle requires the chain to take exceptionally high forces and also, as a result of the mid-drive, it requires 3 complete chains so it was important to pick a chain that could be relied upon.

Custom Gearing and Q-Rings

A Shimano 12-36 9 speed cassette, a 2-1 Mid-Drive Step Down and a Rotor Q Ring chain-set gives a bottom gear of 8.7”. This effectively provides a gear that is twice as easy as a standard mountain bike. The Q rings also help to reduce the negative effects of the dead spot making 1-in-3 gradients effortless.

Hope FatSno Hubs

These specifically designed fat bike hubs are made in England by Hope. They are wider than standard hubs to build up a pair of stronger front wheels which can withstand the extreme conditions of triking in one of the most inhospitable places on earth.
