Cube Reaction Race 625 Electric Bike Rider Review

The 2022 Cube Reaction Hybrid Race 625 is one of Cubes flagship Hardtail eMTB models.

With its incredibly strong and well proven Bosch Generation 4 Performance CX motor, 625Wh battery and trail and climb beating Shimano XT 12 speed group set, the new Reaction Hybrid Race is as ready as ever to take you much further in 2022.

Priced at £3,299, this ultra competitive Reaction will be looking to retain its crown as one of the best equipped and highest value bikes to hit the dirt roads this model year and is suitable for almost all riders, from novices looking to build in future scalability, to regular and more skilled riders looking for their next challenge.

Class leading performance and price..

With the newest Generation 4 Bosch Performance CX System and a 625Wh battery pumping out 85Nm of torque, the Cube Reaction Hybrid Race 625 is ready to take you much further in 2022.

As arguably the best value Hard Tail in the range this year, the Race model is the bike to beat both in stores and on the trails this year, especially now that it includes a set of Rockshox Judy Silver 35 forks up front!

Cube Reaction Race 625 Integrated Frame Design

Fully integrated..

Following a major frame design overhaul last year, the new 2022 Reaction Hybrid Race 625 retains its ultra sleek frame lines with fully internal routing for all cables including the routing and frame ports for an optional stealth dropper post.

The Bosch PowerTube 625Wh battery has been mounted inside the frame to further protect it while enhancing the frame aesthetics. The new super glossy finish on this bike really catches the sun out on the trails!

Cube Reaction Race 625 Shimano Deore Brakes & Gears

Brakes & Gears

Cube have spec'd the Reaction Hybrid Race 625 2022 with Shimano's MT420 hydraulic disc brakes.

Only available on the Race model and above, they offer great performance with very easy reach adjustment. Paired with a 203mm discs up front and a 180mm rear they offer plenty of bite and modulation.

The 2022 Cube Reaction Hybrid Pro 625 eBike is equipped with a full Shimano M8100 12-speed group set.

The Shimano setup with their 10-51t rear cassette offers an unparalleled ultra wide ratio range.

This incredibly wide ratio gearing allows riders to not only ascend some of the steepest inclines imaginable, but also doesn't limit top end speed on flat ground. The Rapidfire-Plus shifters are responsive, positive and crisp - allowing you to simply focus on the ride.

Cube Reaction Race 625 Shimano Deore Brakes

4 piston hydraulic brakes offer ultra strong braking force, perfect for long, technical descents.

Cube Reaction Race 625 Shimano Deore XT Rear Mech

12 Speed Shimano XT gearing is straight from the top shelf of the parts store and only found on top end ebikes.

Cube Reaction Race 625 Shimano Deore Trigger Shifters

Shimano SL-M6100 Rapidfire-Plus shifters are smooth and responsive, regardless of load.

Wheels & Tyres

Cube have used their own 29" EX30 factory rims on the 2022 Reaction Hybrid Race, along with Shimano boost hubs. These 30mm wide rims offer an excellent platform for an ever increasing range of extra width off road tyres.

The wider boost hubs improve the bracing angle for the wheel spokes, improving overall wheel strength and stiffness.

Equipped with Schwalbe's large volume 2.6" Smart Sam Active tyres, the 2022 Cube Reaction Hybrid Race is set up perfectly for riders who find themselves frequently switching between tarmac and dirt, performing effortlessly on both.

The innermost section of this hybrid tyre features a continual tread band for low rolling resistance on tarmac and hard packed surfaces, while the shoulders of the tire have wider more aggressive tread to optimise off road grip during cornering and braking.

Cube Reaction Race 625 Schwalbe Smart Sam Tyres

The bottom line..

Every year, the Cube Reaction Hybrid Race 625 is a hugely popular bike and normally one of the very first Cube models to sell out and we expect nothing different for the 2022 version.

Its popularity, along with the rest of the Cube Reaction range is largely due to its high level of specification for its price point and is always popular for any rider of any skill level looking for an every day XC trail bike.

With incredibly keen pricing and a very well thought out spec list, the new Reaction Race will be the bike to beat out on the trails.
