Flyer ushered in a new era with the Uproc 6 in 2020: An integrated battery, sporty geometry and real pedalling qualities should make the massive E-Enduro attractive to a new, sporty target group. Now the successor with a completely new frame and Bosch's Smart System is in the starting blocks.
Like the Uproc 6, the new Uproc Evo:X, the flagship of the Flyer range, is designed for high speeds and extreme terrain, but thanks to a trick in the design, the bike should still be easy to handle. A point of honour at Flyer: Although the bike is fully designed for trail performance, the battery is still removable.

Major update: newly developed frame and chassis
The previous Flyer Enduro Uproc 6 still came with the "old" Bosch system and 625 battery. In order to integrate the new Smart System with 750 battery into the bike, Flyer has completely redeveloped the frame and also revised the battery removal. However, one requirement has remained the same: The Flyer should be an emphatically stiff bike for maximum steering precision, but now there is also talk of the right flex in the right places for good riding comfort. The predecessor was always considered to be very stiff and not very comfortable, so the new bike should be a little better.
The Evo:X takes the wheel mix with 29-inch front and 27.5-inch rear wheels from its predecessor, as well as the 170 millimetres of travel at the front. The progressive four-bar rear suspension now provides 165 millimetres of travel and is said to have been revised specifically for the Evo:X. Incidentally, the battery is now removed from the bottom of the Flyer Uproc Evo:X instead of from the side as on the previous bike. This offers more potential for lightweight construction and gives the designers more freedom in terms of geometry. For this purpose, the motor has also been slightly rotated, which also saves space compared to the conventional motor orientation.
Ready to rumble: The geometry of the Flyer Uproc Evo:X
Flyer's geometry is correspondingly modern and makes good use of the advantages of the rotated motor and the new battery removal. The rear triangle in particular is very short for a Bosch bike with a lot of travel at 445 millimetres. At 480 millimetres in size L, the reach is modern and long, and the moderate stack should also put a lot of pressure on the front downhill and allow the Flyer to hiss through corners. The steering angle of 64.5 degrees and a flip chip for fine-tuning the geometry are state of the art. This allows you to flatten the angle on the Flyer by half a degree if necessary.
But Flyer has also thought about touring riders with the Evo:X. The seat angle is therefore not too extreme at a maximum of 76.9 degrees in the steepest setting. In combination with the long reach and moderate front height, this should result in a comfortable riding position without too much pressure on the hands, even on flatter sections.
The most important geo data at a glance (size L, flat setting)
- Wheelbase: 1270 mm
- Reach: 480 mm
- Stack: 632 mm
- Steering angle: 64 degrees
- Seat angle: 76.2 degrees
- Chainstay length: 445 mm
From 7399 euros: Models and equipment
The Uproc Evo:X will be available in four equipment variants between 7399 and 12499 euros. Even the cheapest model, the 4.10, comes with trail-ready equipment and a full carbon frame. We have had good experiences with the Domain fork, as well as with Shimano's MT520 four-piston brakes. However, despite the price, the deluxe shock without reservoir, the smaller 625 battery and the eleven-speed Deore make the need to save a little visible.
In the middle are the Uproc Evo:X 6:10 and 8:70 for 8199 and 8999 euros. Both come with a Fox 38 fork and 750 battery. However, the 8:70 gets the better performance version of the fork, while the 6:10 has to make do with the cheaper Rhythm. The 12-speed Deore and the MT520 brakes on the 6:10 trump the 8:10 with XT components, and the Float X2 downhill shock is another upgrade over the smaller Float X.
The top-of-the-range 9:50 model then comes with Fox Factory suspension elements, a wireless X01 drivetrain from Sram and XTR brakes. However, there is still some room for improvement on the equipment side. The aluminium Deemax S wheels from Mavic can still be seen as a conscious decision against carbon wheels, but a bike in this price range should already be fitted with Sram's new transmission. Chic: All bikes come with Bosch's sporty combination of mini-remote and system controller, and the Aquila downhill tyres from Onza also made a good first impression on us.
