Checkout the Video & Pictures of the Haibike XDURO FS RX
The Haibike Xduro FS RX.
The Haibike frames utilize hydroformed 6061 aluminium tubes to create a bike that is engineered to provide a good fit/geometry and reinforcement in the high stress areas.
Internal frame cable routing is found all over the FS RX. Note the wild shapes of the hydroformed aluminum tubing.
For the US market, the Haibike’s come equipped with a Bosch mid drive 350 watt motor (60 Nm of torque) compared to the 250 watt motors found on their European bikes. Mid drive motors power through the drivetrain of the bike and that enables you to climb the steepest hills by shifting to lower gears. The Bosch system is a very advanced system that uses a torque sensor, cadence sensor (crank speed), and wheel speed sensor that takes measurements 1,000 times per second. With that kind of measurements it can sense when you are going to shift the gears and reduce the motor power to make the shifting smoother.
The FS RX comes equipped with the Bosch Powerpack 400 lithium battery. This is a 36V 11ah (400 watt hour) lithium pack that weighs a surprisingly light 5.5 pounds!
On the left side of the bike there is a key lock at the top of pack.
On the lower left of the battery pack is the on/off button, level of charge indicator, and the charging port for on the bike charging.
The Bosch charger is a little larger than a laptop battery charger and it weighs less than 2 pounds. It can charge the 400 watt hour battery pack to 50% in 1.5 hours and 100% in 3.5 hours.
Removal of the battery pack is easily accomplished by unlocking it with the supplied key.
It is nice to be able to charge and store the battery in your house or work place; especially when it is too hot or cold outside.
The Bosch Powerpack 400 is surprisingly small! This is it next to my iPhone 5.
The Haibike FS RX uses a 4 bar linkage rear suspension system with 120 mm (4.75 in.) of travel. Note how the rear shock is mounted in the seat tube area; wild! The chain pulley is used to route the chain around the suspension design.
Here is the back of the rear suspension linkage and 27.5″ x 2.25″ Schwalbe Nobby Nic rear tire.
The Fox CTD LV shock has 3 different suspension adjustments that can be changed with the blue lever: climbing mode, trail mode, and descend mode. The air pressure can be changed with the valve stem on the left to fit the riding style and rider weight.
This is the Shimano SLX rear derailleur with clutch system to prevent chain slap.
Haibike spec’ed the Shimano M615 hydraulic disc brakes on the RS FX. The rear brake uses a 180mm rotor.
A view of the Haibike FS RX cockpit!
The Bosch Intuvia display is front and center on the handlebar. There are 4 levels of pedal assist (Eco, Tour, Sport, and Turbo) in addition to a no assist option that are adjusted on the left side of the handlebar. The display offers information like: odometer, trip distance, max speed, average speed, trip time, clock, and estimated range! There is a USB port on the side to charge your phone or MP3 player on the go. It is easy to remove the display to take with you when you lock up the bike.
On the left side of the handlebar is the Bosch control pad where you can adjust the pedal assist level (+/- buttons) and the information button will cycle through info on the display: odometer, trip distance, max speed, average speed, trip time, clock, and estimated range. Also, you will see the front Shimano hydraulic disc brake lever and lock on grip.
The front view of the left side of the handlebar. There is a button on the front of the Bosch control pad that is a walk assist button for providing a little assist while walking the bike uphill (steps, etc.).
On the right side you will find the RockShox suspension fork lockout button, the Shimano SLX 10 speed shifter and rear hydraulic disc brake lever, and the lock-on grip.
The front side of the right handlebar.
The FS RX comes equipped with the Rock Shox Reba R with 120mm travel and a lockout option. This fork has a 15mm thru axle for added front wheel stability.
The suspension fork lockout is controlled by the button on the right side of the handlebar. Locking out the fork is handy if you are riding on relatively smooth surfaces and want to maximize your out of the saddle pedaling efficiency.
The air spring of the suspension fork can be adjusted by removing the cap and using a shock pump.
Here is a close up of the front 27.5″ x 2.25″ Schwalbe Nobby Nic tire on the FS RX. It has some good tread for off road riding!
The front Shimano M615 hydraulic disc brake uses a 203 mm rotor for solid stopping power.
The Haibike saddle is narrow and has a racing/performance style to it.
