FAQ

Climbing, corning, holding a tighter line, control on loose surfaces and over rocks and roots, snowy, muddy, rainy conditions…Unless you ride on dry pavement 100% of the time, there are situations where every rider could benefit from AWD.

In truth, companies have been attempting AWD systems on bicycles and motorcycles since the early 1900s. It wasn’t until the mid-1990s that Steve Christini finally perfected the concept and made it commercially viable. Who buys CHRISTINI AWD bikes? US and international bicycle dealers sell CHRISTINI AWD bikes to mountain bike enthusiasts, XC trail riders, long-travel extreme riders, and racers.

Mountain Bike Action, DirtRag, Bicycling, and many others over the years.  Check the media archive for more information.

After a year of continuous riding, you will see only minor gear wear if you continue to lube the spiral gear system. In fact, the AWD system shows significantly less wear than the conventional drive train chain, derailleurs, and cassette. The precision aluminum gearing is hard coated and has the strength of steel for this particular application.

5 years on the frame and 2 years on all drive system parts, including the bearings. Components and fork internals carry the original OEM warranty.

Approximately 1.7 pounds on the hardtail model and 2.3 pounds on the CHRISTINI AWD full suspension models and 5″ FAT with the U-joint assembly.

Between 28 and 31 pounds (with pedals) depending upon the model.

In general, proper lubrication and cleaning are all that are required. Special care should be taken to keep the head tube gears lubricated, clean, and dry. The rear clutch can occasionally be disassembled to ensure continued smooth operation. The CHRISTINI AWD service manual has complete service and cares instructions.

Yes. Christini Technologies holds several US and foreign patents on the unique CHRISTINI AWD system. US patent numbers 6,161,854 and 6,161,855 are two covering the AWD Bicycle and can be viewed at www.uspto.gov. US patent number 6,505,699 covers the AWD motorcycle design. Other US and foreign applications are on file

CHRISTINI AWD has executed licenses in the past for its AWD system. In the future, other manufacturers may also become licensees. CHRISTINI AWD also sells its own brand of AWD bicycles and intends to continue to sell its innovative bikes to establish and grow the market.

The AWD system needs an integrated fork crown and dropout to function.  Therefore, on the FAT bikes, a Ridgid Carbon tube is the logical option.  For the 29ers, we have initially chosen RockShox because of our supplier relationship with SRAM.  CHRISTINI and I will continue to use the forks for technical reasons. In the future, other forks will continue to be evaluated for the CHRISTINI AWD products.

Other than the fork, freewheeling front hub, and integrated headset, any standard component is compatible with the CHRISTINI AWD bikes.

The precision aluminum gearing is hard coated and has the strength of steel for this particular application.

Managing two separate motors requires more complex control systems, which can be challenging to fine-tune for optimal performance and can lead to uneven power distribution between the wheels.

Adding a second motor significantly increases the overall weight of the bike, impacting range and handling. In fact, it can add up to 10lbs to the bike and cause adverse suspension dynamics as the front wheel is very heavy.  This makes the suspension inefficient as well.

In slippery conditions, having two motors can lead to excessive wheel spin, making it difficult to maintain traction.
