KHS 6555+E: Precision and Power for Race-Ready Performance
The KHS 6555+E showcases genuine enduro geometry, making it our most robust and capable e-MTB to date. Setting the standard for e-MTB race and trail bikes, the KHS 6555+E offers precise handling, allowing you to navigate every turn confidently and launch off any jump.
Equipped with a FOX Factory Float 36 160mm fork and FOX Float DPS for rear travel, this bike delivers a ride that balances capability and agility, all within a rugged, high-performance race package.
Unmatched Power, Precision, and Versatility for Every Ride
The KHS 6555+E is a meticulously engineered high-performance e-MTB designed for serious riders, featuring a robust 4Bar Horst Link frame with 150mm travel made from durable 6061 aluminum, ensuring both lightweight agility and strength for tackling challenging trails.
The choice of a FOX Float DPS rear shock (210x50mm) with a 3-position Evol adjustment allows for tailored performance, while the FOX Float 36 fork with 160mm travel, Grip Sweep Adjust, and external rebound adjustability provides superior handling and stability on rough terrain.
An FSA Orbit 1.5E zero stack headset enhances steering precision, and the WTB Scraper i30 TCS aluminum rims are tubeless-ready, promoting lower weight and better traction.
The Shimano HB-M7110-B and FH-M7110-B hubs, designed for Boost spacing, ensure a stiffer wheel setup for improved power transfer. Kenda Regolith Pro and Pinner Pro tires were selected for their exceptional grip and durability, essential for varied trail conditions.
The drivetrain features a Shimano XT RD-M8100 rear derailleur and 12-speed Shimano XT shifters for precise and reliable gear changes, complemented by a Shimano CN-M7100 chain and a Shimano FC-EM600 crankset with a 34T chainring for optimal climbing efficiency.
Powering the bike is the Shimano EP-801 motor (36V, 250W, 85Nm), paired with a 36V, 17.5Ah (630Wh) lithium battery, providing ample power and range for long rides. The Shimano CS-M7100 cassette with a 10-51T range ensures versatility across various terrains.
A Kind Shock Rage-I remote-adjustable seatpost allows for on-the-fly height adjustments, enhancing comfort and control. The medium WTB Volt Sport saddle, FSA Grid 1 Riser handlebar, and forged FSA Grid stem contribute to a comfortable and confident riding position.
Finally, the Shimano MT420 4-piston hydraulic disc brakes with 203mm rotors offer reliable stopping power, making the KHS 6555+E a well-rounded choice for riders seeking performance, durability, and versatility in racing and on the trails, all presented in a sleek black finish across three frame sizes: Medium (16.5"), Large (18"), and Extra Large (19.5").
