How do you improve on near perfection? It's a good question. Having completely redesigned our Reaction Hybrid frame for 2017 we wanted to eke the maximum possible performance out of its newly tweaked geometry. The answer was to select the very best components, topped off with SRAM's revolutionary 1x12 Eagle transmission. The result is our Rection Hybrid Eagle. There's no better-handling, better-equipped aluminium e-MTB hardtail: fact.


Frame: Our Reaction Hybrid frames were already popular choices with clued-up riders. They knew that our Agile Ride Geometry and huge experience in building e-MTBs translated into a great handling bike. But we knew we could do better, so we went back to the drawing board to create a brand new chassis, incorporating the motor and battery unit into the frame to give the 2017 Reaction Hybrid two key advantages over its predecessor. First, careful positioning of the powerful Bosch drive unit has allowed us to improve the geometry even further anb brings steering and agility to a level that you'll find hard to believe. And second, now there is space for an bottle cage holder in the front triangle.


Features: Bosch's powerful CX drive unit is the Reaction Hybrid Eagle's beating heart, providing up to 75Nm of climb-devouring torque, even for extended periods - and the 500Wh battery is standard, so you've no worries about running out of charge. We harnessed the new geometry's superb handling by speccing Rock Shox's genre-busting RS-1 upside down fork and a set of light DT Swiss CSW AM 2.0 with 2.6in Schwalbe Nobby Nic tyres. And we finished this range-topping bike with SRAM's new 1x12 X01 Eagle transmission. The huge gear range and simple, single control shifting could have been made for e-MTBs…
