Santa Cruz Heckler 8.1 CC MX S Kit E-Bike 2021

Let the heckling begin

The mountain biking community will never see eye-to-eye on all things related biking and there will always be differing opinions on the ever-evolving technology and ways of riding that are flooding our trails. So for good measure, Santa Cruz decided to combine various controversial topics and put them into one bike and give it a very fitting name. Introducing the 2021 Santa Cruz Heckler MX, a mid-travel E-MTB with “mullet” wheel sizing and progressive and slack geometry. The 2021 Heckler 8.1 MX features many different changes from its previous versions, including shorter travel, a lighter, faster and more efficient motor and a replaceable battery. With the addition of the mixed wheel size, the geometry of the heckler is now more capable than ever. The headtube angle drops to a slack, 64.6 degrees and the seat tube angle is dropped to 75-degrees for more capability for when the trail points downwards. The Heckler keeps its medium-sized chain stays and 27.5” rear wheel to maintain agility, while the addition of the 29” front wheel adds traction and stability, making for a bike that has the best of both worlds. The MX drops the Heckler’s front and rear travel down to 140mm for a more mid-size bike feel and was given an anti-squat tune for better pedaling efficiency as well as improved suspension performance on technical climbs. The combination of Santa Cruz’s VPP Suspension system, 140mm of travel and a unique suspension tune makes the MX an all-mountain machine designed to send you up technical climbs with grace and boost you down rowdy sections with ease. Santa Cruz gave every build of the 2021 Heckler their premium Carbon CC frame that includes a Shimano 504Wh Integrated battery, Shimano’s new EP7 or EP8 motor and E7000 or EM800 display units. Shimano’s new STEPS EP8 motor is lighter, more powerful, more efficient, quieter, and much smaller in size than the Heckler’s previous versions drive units.

The S-kit build of the 2021 Santa Cruz Heckler MX E-Bike is outfitted with quality components and was built for performance on the trails. First up, a SRAM GX Eagle 12-speed drivetrain, which offers an impressive 10-50 tooth gear range, helps get you up any technical climb. Next, a RockShox Pike Select+, 140mm, 29" Fork paired together with a Fox Float Performance Elite DPS rear shock for a world-class suspension system that was designed to shred mountain terrain with ease. Santa Cruz slapped on their new Di2 Carbon handlebar for a super-strong and lightweight cockpit. Last but not least, RaceFace AR Offset 30 29”/27.5” rims with DT Swiss 370 hubs are paired with premium Maxxis tires for a wheelset and tire combo capable of taking on the rowdiest of trails.
