Highlights
Faster and lighter: the race motor
The "Bosch Performance Line CX Race" is 150 grams lighter and offers support of up to 400% in Race mode. Compared to the "Performance Line CX" with 340%, this is 60% additional support. This means you are even faster on the road and one step ahead of the competition.
Stable, more stable, most stable
Experience a particularly direct riding experience thanks to the extra-stiff frame: the high-strength carbon ensures perfectly balanced frame rigidity.
Integrated controller
The controller with LED display integrated in the top tube gives you full control of your e-bike - without any frills or distractions.
Carefree connectivity
Thanks to the GPS "ConnectModule" and smartphone connections, you can track each of your tours. You also benefit from increased theft protection by locking your e-bike, triggering an alarm in the event of unwanted movements or tracking every movement via GPS.
A chassis for the roughest terrain
Flyer has developed the kinematics of the full-suspension chassis especially for its e-bikes. The 165 mm suspension travel provides a great deal of safety and allows you to master even the roughest terrain.
Cleverly combined wheels
The combination of 29-inch front and 27.5-inch rear wheels combines the advantages of both wheel sizes: The larger front wheel ensures the best rollover behavior and optimum grip. The more compact rear wheel allows you to ride agilely and dynamically.
Uproc EVO:X
Comfortably up the mountain, at high speed down the mountain: The Uproc EVO:X is your perfect E-Enduro mountain bike. It combines uncompromising power and riding fun. Its chassis is consistently designed for enduro use. The frame is extra-stiff - and still offers you the necessary flex in the right places. The minimalist design with wireless controller and display in the top tube is also perfectly thought out.

#TheNewFast - Performance Line CX Race Limited Edition
Features at a glance
Exclusive Race mode
The riding mode specially developed for eMTB racing impresses with energetic, direct support - with 400 percent of your pedal power.
85 Newton meters
Extremely fast acceleration after tight bends and obstacles gives you the decisive competitive edge.
Powerful design
The Performance Line CX Race in graphite gray impresses with its sporty, confident look.
Hill start assist
Start off more easily on steep terrain: put your foot on the pedal and hold down the minus button.
Functions and details
The best of both worlds
EMTB+ mode combines the precise controllability of eMTB mode with the full power of Race mode and bridges the gap between the two modes.
Exclusive Race mode
Race mode has been specially developed for use in eMTB races and is available exclusively for the Performance Line CX Race. The riding mode gets you up to top speed quickly and supports you with its full power up to maximum speed - for the decisive seconds in the battle for the best time. The Extended Boost known from eMTB mode is also available in Race mode - but with an even longer boost. It is ideal for quickly overcoming large boulders and complex root passages. A precise riding technique is required to control the energetic response and power of Race mode. It was developed with the expertise of successful eBike athletes.
85 Newton meters of powerful acceleration
The maximum torque of the Performance Line CX Race of up to 85 Newton meters enables rapid acceleration - from a standing start, after extremely demanding sections and obstacles, tight bends or hairpin bends. The power of pedaling is immediately converted into propulsion. Even at high pedalling frequencies of more than 120 revolutions per minute, the powerful motor provides powerful support. Sporty riding over long distances and fast sprints are possible - ideal conditions for best times on demanding routes.
Low weight and compact design
The Performance Line CX Race weighs just 2.7 kg. The low weight contributes to a lower overall weight of the eBike - ideal for more control uphill and downhill, fun on jumps and easier negotiation of carrying and pushing passages. The integration into a sporty, slim frame geometry optimizes handling and ensures agile handling.
Sporty design
The housing of the Performance Line CX Race has a high-quality graphite grey finish and stands out visually from other drive units thanks to its logo and accent colors. The slim design and the special surface finish underline the robust, sporty and strong character of the drive unit.
Hill hold on sporty routes
The Hill Hold function of the smart push assist prevents your eBike from rolling back unintentionally when pushing on extremely steep slopes and impassable passages. This means you can push your eMTB much more easily and make faster progress on strenuous and tedious climbs on foot. In extremely tight and steep bends, you can use Hill Hold to move the eMTB in a controlled manner, for example.
Push assist or hill start assist
Press and hold the minus button and start pedaling: Thanks to the smart pushing aid, you can push your eBike more easily. The integrated Hill Hold function also prevents your eBike from rolling back unintentionally. Put your foot on the pedal and hold down the minus button: With the hill start assist, you can start off in a relaxed manner - even on steep terrain.

LED indicators
LEDs use different colors to indicate the riding mode as well as the battery charge level in 10 % steps.
Connected in the smart system
The System Controller makes your eBike smart – and is the interface for software updates.
Built into the top tube
