Folding / Split Down Features - B2
The B2 is a dual 26 inch wheel bike and so is not the obvious choice as a folding bike. However, it can still be made smaller for transport due to some unique features.

The routine for full splitting and folding the B2 works as follow:-

• Quick release front and rear mudguards if fitted.  These clip on and off in seconds and are light weight.
• Seat is removable with quick release levers.
• Remove the QR rear wheel
• Remove the QR front wheel
• Shorten the boom
• Fold the handlebars down to the front forks
• If this is still not small enough then the B2 has the clever trick of the rear frame section being removable -
• Unclamp the 2 x M6 main frame bolts, unhook the rear derailleur and rear brake cables and remove the rear frame section. (this is only recommended for major journeys but the B2 is unique in being a high racer style bike that can do this).

Frames
ICE bike frames are a combination of Cro Mo steel for the main tube and 7005 Aluminum Alloy for the front boom and rear section. All frames have detail braze ons for cable guides and other mounts as required. Using steel for the main tube gives a strong yet compliant ride adding to the overall comfort.
The front boom and rear section are both made from heat treated aerospace Aluminium alloy for light weight, stiffness and enhanced power transfer from the pedals to the wheels.

Seats Options and Seat Angle Adjustment
The B1 comes as standard with our tubular aluminium seat with mesh fabric cover giving excellent comfort and ventilation. The fabric is laced onto the aluminium seat frame with adjustable straps. The seat is clamped onto the main frame with QR levers and can be removed easily and quickly without tools for transport. The seat angle is quickly adjustable to 5 settings and can be done at the road side in seconds if desired.

The B2 comes as standard with a composite hard shell seat which has a luxurious breathable Ventisit comfort cover as standard and the package is available in a Medium or Large size. The hard shell seat makes it easy to get your feet on the ground with the higher seating position of the dual 26" B2.

The hard shell seat is also available as an optional upgrade on the B1, generally for the more sporty rider.

Rear Suspension - B1 only
Standard on the ICE B1 in heat treated Aluminium the rear suspension gives a superbly comfortable ride by smoothing out any bumps coming up from the rear wheel.
The suspension pivot also has the double function of allowing the simple folding of the swing arm.

Elastomer Springing and Damping - B1
The B1 uses the same well proven suspension system as the Trice Q or T but re-tuned for use on the bike. The benefits of an elastomer over an air shock are:

• Elastomers are lighter in weight than an air shock, as well as resulting in a more compact installation.
• Elastomeric materials provide a natural damping that is ideal for suspension.  There is also no initial stiction (http://en.wikipedia.org/wiki/Stiction) to overcome (often found with more complicated gas or oil damped units., resulting in a more responsive suspension over coarse road surfaces and small bumps.
• Elastomers are zero-maintenance, with no seals to maintain or air pressures to check.
• Using a combination of 2 different compounds and 5 different mounting positions, the suspension can be easily and quickly tuned to accommodate a wide range of body weight, rack loads, and rider’s preference.  The suspension can be adjusted on the road by the rider without the use of tools.

The B1 is shipped with the standard RED elastomer, harder GREEN elastomers are available to order if you are heavier.

If you are setting your bike up with a heavy touring load then we recommend adjusting your suspension correspondingly to get the best results.

Steering Stem
ICE bikes come with a custom highly adjustable light weight handle bar stem which can be set for height and stop angle. Through careful design we have made it reversible to allow simple switching of optional straight or wrap around handlebar styles.
Even the cable lengths remain the same when changing between bar styles!
The stem tilts forward for easy access with an adjustable stop system and simple adjustable friction damping to control pivot stiffness.
Careful cable routing and pivot design allow the stem to be folded right down beside the front forks when the B1 or B2 are folded for transport.

Handlebar Options
Two types of handlebars are available for the B1 and B2 allowing customization to your preferred arm position.
As standard the the bikes come with straight bars giving good clearance to your knees and lower legs in tight maneuvers and a relaxed arm position. These bars also result in a slightly more compact fold.

Alternatively we offer wrap around bars as an optional extra which tend to restrict leg movement in slow very tight turning but give a more straight arm position and a speedy look and feel. Bars can initially be changed from one type to the other without changing cable lengths so experimentation to determine your personal preference only requires 1 extra set of bars. In most cases a test ride with us or at your dealer will quickly confirm your favorite setup.

Under seat steering is not offered on the ICE bike range.

Compact Drive System - B1 only
The ICE B1 uses our unique rear hub and custom 9-32 rear cassette which gives a very practical gear range with the 20" wheel. We then use a road compact front chain set keeping the whole package small and neat with excellent shifting and light weight efficient all derailleur gears.

Custom Hubs
The B1 uses our top quality custom rear disc hub designed for use with our special 9-32 wide range cassette. This hub has 4 simple sealed cartridge bearings and can be dismantled easily if maintenance should be required.

The B1 and B2 use a high quality front hub which matches the rear, again with sealed cartridge bearings. The light weight package is completed with hollow steel QR skewers.

Avid Disc Brakes
The ICE B1 and B2 come with the excellent Avid BB7 mechanical disc brakes front and rear as standard. We experimented with rim brakes on our early prototype bikes but quickly found them to be insufficient in our harsh Cornish riding conditions. Wet weather and heavy braking on down hill stops soon showed that using the rim surface was too unpredictable for confident and safe riding. The SRAM BB7s are well respected and spares are easy to source. They are also simple to adjust for pad wear without the use of tools and maintenance of the cable operation is simple.
