Heckler Tech


Full carbon frame, VPP suspension and pedal-assist merge to create a platform that feels light and agile yet with the power to make rare rides the norm. Discover what makes Heckler tick.

VPP Kinematics

The 150mm travel lower-link VPP design marries the needs for downhill kicks with efficient pedalling prowess. We tuned it to have lower anti-squat (to sag) than our regular pedal bikes to allow you to keep pedaling (while seated) where normally you’d start standing. The more active suspension while pedaling creates better traction on technical climbs. But once you start mobbing down the trail the lower-link VPP system provides more mid-stroke and bottom out support than most other designs.

CC Frame

CC Carbon Frame

The full CC carbon frame (front and rear triangle) and battery cover is lightweight and bombproof; the geometry is perfect for all-round modern trail riding; and the 150mm-travel lower-link VPP design is the most refined suspension design on any e-MTB. 

Like every Santa Cruz, the Heckler is built for the rigors of true mountain biking. With quality pivot hardware, radial bearings (with lifetime replacement support), simple internal cabling and wiring, clean lines, design and build kits, and a lifetime warranty.

What the Heck

Riders like Danny MacAskill aren’t looking to Heckler for a dumbed-down ride up, or down. The potential to loft them to new heights while pushing their riding to new levels is what excites them most. That’s why we held maneuverability sacrosanct for our first foray into this category, and why Danny asked to do our first proof of concept.

Performance, Reliability, Fully Supported

These are three traits our bikes are legendary for, so when we build a complete bike we always pair our frames with components that are regarded similarly. For the all-important drive unit we used entirely Shimano Steps components - battery, charge port, power button, controllers. This means all parts, service and warranty is available through Shimano and Santa Cruz. Shimano stock e-parts through distributors and retailers the world over, the Shimano E-Tube app can troubleshoot any issues, and there’s already robust retailer training through S-Tec, consumer websites and a network of technical product support teams. 

The Shimano motor and battery, as well as the whole parts spec was carefully chosen for performance, reliability and support.

Shimano STEPS

The 250-watt Shimano Steps E-8000 motor is compact and light (6.34lbs/2.88kg) meaning it helps us build one of the lightest e-MTBs out there.

504wh Integrated Battery

The E-8035 battery is Shimano’s latest integrated battery. It provides 500 watt-hours of power, is lightweight (6.4lbs/2.9kg), is fully removable/replaceable using just a keyless 4mm hex latch and is protected by a Santa Cruz CC carbon battery cover.

Smart Spec

The Shimano STEPS system is also devoid of any large, clumsy displays that are impractical in real mountain biking situations. Moreso, there’s less to go wrong or break in case of an tumble.

We used Shimano’s two compact E-8000 (color) and E-7000 (B&W) displays paired with a E-7000 mode switch to create a simple integrated cockpit. The switch is unobtrusive, intuitive and has the best dropper lever compatibility. The Shimano Steps app can be connected via Bluetooth or plug-in to adjust the power settings of the drive unit. It also allows for powerful management of the assist levels of the three support levels (two preset and one custom mode) of the Eco, Trail and Boost modes. It also provides diagnostic capabilities to troubleshoot any issues you may have.

Santa Cruz Di2 Handlebar

We want the riding experience to come first, so we made the integration of the motor controls seamless by creating our very own Santa Cruz Di2 carbon handlebar. The internal switch wiring (under grip groove and routing holes) results in a clean, tidy cockpit, free of clutter and loose hanging wires. The bar itself is 35mm diameter, 800mm wide, with a 5-degree upsweep and 8-degree backsweep. Moreso, the bar has the same Di2 groove and holes on both sides in case you do wish to further integrate a complete Shimano Di2 drivetrain (or other wiring fixtures). This bar comes stock on Complete Heckler bikes S-level and up, and is available aftermarket.

Reserve DH rim

Reserve rims are already renowned as the strongest, most trusted carbon options for MTBs so it makes sense to use an even beefier version for the Heckler – which will be ridden harder than ever, for longer, more often. It’s paired with a 28-hole Reserve 30 wheel up front and the hubs are all super reliable DT Swiss and Industry9 hubs that have quick engagement and dependable under the kind of loads that are likely when the extra torque of the motor-assist is available. Like all Reserve wheels these have a lifetime warranty.

The Reserve wheelset is standard on the X01 and XX1 build kits but is also available aftermarket.
