The Santa Cruz Heckler SL C S is a lightweight electric mountain bike built for trail riding. It pairs a 150mm VPP suspension frame with Fazua's compact 60Nm mid-drive motor and a 430Wh battery, aiming to deliver natural handling with pedal assistance. The mixed-wheel setup (29-inch front, 27.5-inch rear) and progressive geometry are designed for agility on descents and efficient climbing. Riders who want a nimble eMTB that feels like a regular trail bike will appreciate its low weight and silent motor, though it offers less torque than full-power e-bikes.

Reviewers praise the Heckler SL for its natural trail feel and quiet motor, though some note the higher cost and modest power compared to full-size eMTBs.
The Heckler SL C S is a mid-power electric trail bike. It pairs a Fazua Ride60 compact drive unit with a carbon frame that has 150mm of VPP suspension travel. The bike uses mixed wheel sizes: 29" in front and 27.5" in back.
The Fazua 60 drive unit is described as fluid and silent, with zero drag. It is a lightweight unit, and together with the MX wheel sizing it keeps the handling natural and familiar. The 430 Wh integrated battery is compact and gives the same range as a 630 Wh battery on a full-powered eMTB.
Components include a RockShox Lyrik Select+ fork with 160mm of travel, a SRAM GX Eagle 12-speed drivetrain, SRAM Code R brakes with 200mm rotors, and a OneUp dropper post. Pedals are sold separately.
